If CO2-induced climate change is defined as extreme weather disasters, then recent years are proving to be a bust...likewise, the much feared rapid and ferocious global warming predicted - from CO2, of course - has turned into an insignificant pussy cat, per the GISS/NASA climate records.....

By year 2050, how much warmer will it be?
As the climate "experts" and $billion$ computer models have proven decisively, they are completely clueless when it comes to predicting future global temperatures.
Fifteen years ago, this graph's red curve, representing temperature trends, was tracking right along with the CO2 grey curve - such that, as of the end of September 1999, the 10-year temp trend was on a 2050AD warming pace of +1.1ºC.
But as the adjacent chart now reveals, by end of September 2014, that previous +1.1ºC trend has changed to a -0.03ºC cooling trend despite the continuous acceleration of atmospheric CO2 levels. A powerful testament to the overwhelming significance of natural climate change that far exceeds the influence of of a trace gas such as CO2.
And remember, not a single IPCC or NASA/GISS "expert" predicted this outcome - just the opposite in fact.
As the graph's red plot depicts, global warming trends have been on a deceleration path for an extended period, indicating a strong likelihood that global warming by 2050 will be nowhere close to he current official predictions.
Did we mention 'pussy cat' warming yet?
Obviously, the "settled" science of slam-dunk global warming is in shambles. And natural climate change made it so, much to the chagrin of those elites pushing "consensus" anthropogenic dogma.
Without doubt, in the scheme of urgent, priority issues facing the nation - global warming ain't one of them, which the American public already knows and reflects.
The climate-doomsday cult has long stated that coastal areas of the world are being swamped by accelerating sea rise due to rapid "global warming"...fortunately, skeptics of global warming alarmism have been proven right by the latest empirical research....
EU researchers analyzed multi-mission satellite records in a new study and determined the following:
1. A huge bulge in the Western Pacific is responsible for much of the past "global" sea rise.
2. Since 2002, sea level rise has greatly decelerated.
3. Globally, on average, sea levels are currently increasing at a 2.31 mm/year rate (that's a 3.2 inches by year 2050 rate).
This research confirms what other scientists have already recently found by analyzing tide gauge records around the world.
For example, a group of scientists examined sea level rise around the North Sea. What they discovered was an absence of evidence confirming the doomsday predictions of soon-to-be submerged coasts.
==> "Based on their analysis of all the available data, the four researchers determined that "linear long-term trends in the Inner North Sea (1.6 mm/yr) are similar to global trends (1.7 mm/yr) but smaller in the English Channel (1.2 mm/yr)." And they report that "although the recent rates of sea level rise were high, there is no evidence yet that sea level rise has accelerated over the last decades in the North Sea region.""
A 1.7mm/year increase converts to a 2.16 inch rise by 2050AD and for the English Channel, 1.2mm/yr equals 1.8 inches by 2050.
Conclusion: Ahhh...those damnable stubborn facts. By 2100, and certainly 2050, the North Sea coastline (and others across the globe) will retain its majestic beauty, still existing as it is known today. Thus, proposed trillion dollar tax hikes and higher price schemes for fossil fuel usage are a total waste since lower cost adaption techniques can be effectively implemented to deal with the such meager rises the world likely faces.
Climate change, as represented by global cooling and global warming trends, is in a constant flux...the IPCC's gold-standard temperature dataset provides the empirical proof that a natural cycle of ups and downs is the reality - past, present & future.....
(click on graph to enlarge)
How much global warming (or cooling) will take place by 2050AD?
The flat-out, scientific truth is that nobody really knows. Not the IPCC. Not the climate models. Not the experts. And certainly not the green crony-facilitators, Naomi Klein and Bill McKibben (fyi...crony Al Gore just loves them to death.)
This chart plotting the IPCC's gold-standard (HC4) of global temperature trends, of past and present, reveals why it is so incredibly difficult to predict climate change, be it of short or long-term nature. Climate change is constantly happening - going from one warming acceleration to the next cooling acceleration extreme, rather rapidly.
And note, this takes place regardless of atmospheric CO2 levels (see black curve), and associated human CO2 emissions. Clearly, the skyrocketing CO2 levels since the 1950's are not responsible for such wide variance in temperature trends, since they can even be observed a century before.
In fact, based on a visual inspection, one could surmise that climate change extreme trends have lessened since the modern increase of CO2 levels.
As can be seen, shorter cooling/warming trends have been highly variable from the very start of recording instrumentally-measured "global" temperatures. The light red (12-mth) and green (60-mth) plots readily show this.
So, when did the greatest acceleration of warming trends take place? Amazingly, all the warming spikes that matched or equaled ±20°C took place (see yellow-tinted boxes) prior to the last 40 years of massive human CO2 emissions.
Regarding the 10, 20 and 30-year climate change variability, there is no question that the wild and natural extremes of the short-term always return to a rather mundane long-term variability. The dark blue, cyan and bright red plots indicate long-term climate change that is...well...pretty mundane.
Compared to a 12-month climate change extreme trend of +25.0°C reached in 1878, the 30-year trend extreme only reached a maximum of +0.72°C (during 2003) and has now been reduced to a August 2014 30-year trend of 0.61°C - and relative to the 1940's, that's a trend only eight-hundredths of a degree greater.
Conclusion: Climate change never stops. Whether short-term or long-term, global temperature trends constantly accelerate/decelerate. Human CO2 emissions have nothing to do with this extreme variability - it is a natural phenomenon that is chaotic, totally unpredictable and unstoppable. The climate change indicated by today's temperature trends is insignificantly different than the past climate change. And those are the stubborn facts.
Note: Linear temperature trends do not represent predictions (any trend today can be drastically different in the future). Excel's slope function was used to calculate the moving trends for each time span (by month) and to plot them. To calculate the trends by 2050AD, the derived slope for each month and each time-span trend was multiplied by 424 months (after August 2014, there are only 424 full months until January 1, 2050AD). HadCRUT4 global dataset and CO2 (ppm) datasets used for chart can be found here.
Ahhh, those stubborn facts...it's now been two decades+ that the public has been warned about the existing dangerous and rapidly accelerating global temperatures...a warming that was supposed to produce catastrophic doomsday climate changes...except it hasn't happened, which the gold-standard of global surface temperatures document.....
(click on chart to enlarge)
Has two-decades worth of cumulative CO2 growth in the atmosphere caused the "experts'" predicted dangerous and rapidly accelerating global warming?
That's the straight-forward question.
And the straight-forward answer is?
Well, despite all that CO2 growth, global warming has slowed to a creep on the Earth's surface, and in the atmosphere, global warming has flat-lined.
Using the IPCC's gold-standard global surface dataset (the UK's HadCRUT4), this chart plots the cumulative growth in temperature along with NOAA's reported cumulative growth in atmospheric CO2 levels (ppm).
For CO2 (grey curve), there is a clear and consistent upward growth of CO2 levels - unrelenting would be an apt description. In contrast, global temperatures are all over the map, with highs and low being constantly...er, variable.
The end results over the 20 years ending August 2014 are fairly obvious:
The visual relationship between CO2 and global temperatures appears to be very weak; in fact, statistically the r2 is 0.19, which can be interpreted as being close to a zilch relationship.
Per both the 2nd order fitted trend (blue curve) and the 36-month moving average (red curve), the deceleration of the global warming trend and a plateauing can easily be seen.
Over the 20 years, there have been exceptional warm(-est!) months/years, often followed by exceptional cool months/years.
And since September 1994, the exhibited warming trend amounts to a measly increase of a non-doomsday +0.38°C by year 2050AD.
How easy is it to say, three times quickly?: catastrophe-climate-doomsday-cult-is-discredited.
So, does all the above empirical evidence mean that human CO2 has no impact on global temperatures? Nope. Does it mean the world will no longer warm? Does it mean humans don't have an impact on continuous natural climate change? Nope. Does it mean that the world should quit trying to be energy and carbon efficient? Not at all.
What it does mean, though, is that the public and the policymakers were greatly deceived by the "consensus" science and computer models that loudly declared (and btw, still do) imminent disasters and doomsday global warming.
As the current climate conditions now indicate a slow, creeping climate change scenario, it provides policymakers and the public the luxury of time to continue moving to a more carbon-efficient economy, thus improving the environment without needlessly sacrificing quality of life and living standards.
In summary, it's another case of those stubborn facts: the empirical evidence does not lie; but computer models and "experts" do.
Note: Download HC4 and CO2 datasets. Excel used to make calculations, trends and chart. The chart covers 240 monthly records, starting with Sept. 1994. For this graph, both the temperature and CO2 datapoints were set to zero; then the cumulative changes for both were plotted each month - does not affect linear trends when done this way.
Every time there is a forest fire (ie wildfire) global warming alarmists, like a pack of Pavlov's dogs, start hysterically howling that human CO2 caused the recent incendiary event...while at the same time claiming their predictions of increasing wildfire damage from CO2-warming are coming true...however, like always, the empirical evidence proves the alarmists are without scientific portfolio.....
(click on graph to enlarge)
Let's cut to the chase - are human CO2 emissions causing an increase in U.S. forest acreage being decimated by flames?
The adjacent chart is a plot of U.S. wildfire acreage going back to 1926, through the end of 2013. The green curve represents acres burnt (in millions).
In addition, the chart includes the plot of lumber harvested (billion board-feet) from U.S. forests and atmospheric CO2 levels over the same approximate time span. The brown curve is the lumber harvest; the grey curve is CO2 (ppm).
What does the chart indicate?
Wildfire acreage burnt collapsed after the 1930s. Not only did this collapse coincide with a growth of atmospheric CO2 levels from human CO2 emissions, the huge decrease in acres burnt took place when the harvesting of lumber from U.S. forests grew massively.
Then, as the total amount of harvested lumber declined and reached a significantly lower level - due to new environmental regulations - the number of acres burnt each year started to incrementally increase during the 1990's.
Intuitively this makes sense. As the dead and disease-infected trees started to pile up from lack of harvesting due to environmentalist concerns and government regulations, the U.S. forests became wildfire tinderboxes, easily set off by lightening and human carelessness - the law of unintended consequences from passionate 'green' policies strikes again.
Per the statistical relationships, both board-feet harvested and CO2 levels have an inverse correlation (-0.6 and -0.5, respectively) with the acreage scorched, across the entire time span.
Conclusion: It's always dangerous to draw firm conclusions from just statistics, but the empirical evidence strongly suggests that both lumbering and higher CO2 levels makes for less wildfires. The record clearly shows that wildfire damage over the last two decades are not unprecedented, and it remains well below the horrendous amount of acres burned during the early 20th century. For policymakers, the sanest recommendation towards improving U.S. forest health is to increase the amount of allowed lumbering, thus thinning forests of tinderbox materials; plus, to recognize any future CO2 increases as a potential contributor to healthy forest growth.
Note: The wildfire acreage burned during years 1926-1959 and the lumber board-feet harvested came from this congressional testimony by scientific forestry expert; post 1959 data from this government agency site. CO2 datasets found here. The chart's right axis represents both atmospheric CO2 levels and harevested board-feet. For the latter, the largest number at the top, '1300', reads as 13 billion board-feet; for CO2, it would read 1,300 ppm.
The consistent failure of the IPCC's climate models is widely recognized by the scientific experts...the models inability to predict future climate scenarios accurately is partly a result of thousands of key failures, including their being unable to simulate the asymmetry of ENSO....
Besides the current crop of IPCC climate models failing due to their being CO2-centric, the models also suffer failure from the thousands of sub-simulations they are required to perform.
It is known that there exists a major asymmetry of the El Niños versus the La Niñas. If climate models can't accurately simulate this asymmetric relationship it makes for poor global climate predictions.
Scientists published a recent study to determine the success of modeling the ENSO asymmetry - the results were not encouraging.
===> "With respect to their findings, Zhang and Sun report the following: (1) "the underestimate of observed positive ENSO asymmetry measured by skewness is still a common problem in CMIP5 coupled models," (2) "all the models are also found to have a weaker ENSO asymmetry than observations," (3) "CMIP5 coupled models have a significant cold bias in the mean sea surface temperature," (4-6) "biases in zonal wind stress, precipitation and subsurface temperatures ... are also too symmetrical with respect to ENSO phases," (7) "sea surface temperature warm anomalies over the far eastern Pacific are found to be weaker in the coupled models than in observations," (8) "most models also have a weaker subsurface temperature warm anomaly over the eastern Pacific," (9) "most models have a weaker precipitation asymmetry over the eastern Pacific," (10) "most AMIP models have a stronger time-mean zonal wind over the equatorial central and eastern Pacific," and (11) they "underestimate the observed positive skewness of zonal winds in the central Pacific.""
Conclusion: The multi-billion $$ climate models have proven time and again that they are incapable of predicting future climate with any level of accuracy. Policymakers would be best served by completely ignoring the computer simulations as they poorly match the empirical observations of the global and regional climates. However, the models still hold value for the researchers, but that is their only benefit.
Even the most die hard, green climate scientist who spouts CO2 catastrophe hysteria does not really believe in the unicorn of climate mythology - the mythical CO2 'control knob' - an anti-science myth pushed by the likes of Al Gore, Bill McKibben, Obama and scientist Leo DiCaprio...and there is a very substantial reason why scientists don't believe it...all the empirical evidence easily refutes its existence.....

Climate scientists who are not of the payroll of 'Big Green' NGOs, nor dependent on government research grants, find it much easier to speak out against the utter nonsense and myths of anti-CO2 activists and the slimy crony-greens.
An example: As climate scientist Judith Curry indicates, there is no basis for a magical 'knob' that would allow today's politicians and bureaucrats to dial-in a desired climate outcome for next month, or the next year, or the next decade, or the next century.
The facts, simply stated: There is no science, no computer model, nor any available mechanism(s) that would allow today's humans to tweak CO2 emissions a certain way in order to produce a future climate of specific attributes by, say, 2050.
It's what is referred to as, "no frakking way."
The inner circle of establishment climate science knows this, yet due to political agenda reasons, they are forced to deliver lip service to the ludicrous 'knob' analogies.
The massive failure of billion$ climate models and the ongoing 17+ year pause in global warming provide the necessary and vivid testimonials to the fallacy of a climate thermostat knob, whether controlling natural and/or human CO2 emissions.
In addition, there is the latest empirical evidence that completely invalidates the 'knob' assertion.
This adjacent plot of 5-year temperature change versus 5-year atmospheric CO2 level change is based on the most recent empirical evidence published by the government's GISS/NASA scientists (and they happen to be some of the largest proponents of chicken little global warming calamities).
This empirical science published by NASA is undeniable, and most alarmist scientists accept, although grudgingly - the relationship between changes in atmospheric CO2 levels and changes in temperature are, at best, significantly lame weak.
Indeed, the two dataset plots reveal zero relationship with a correlation that produces a r2 barely above zero. A non-existent relationship from 1880 to the end of August 2014,
Look at the green and red fitted trends. Obviously, the green CO2 trend exhibits rapid, accelerating and even exponential growth after 1950. And the global temps? The red temperature trend depicts very little growth in temperature change, and currently exhibits a deceleration that climate models and "experts" never predicted.
In fact, one could surmise that the temperature changes reflect a natural cycle of ups/downs (ie. a pattern), which the accelerating CO2 growth has absolutely zero influence on.
Ergo, the 'control knob' proposition has the same likelihood of reality as those space alien abductions one reads about, Big Foot enrolling at Univ. of Washington, Congress balancing the budget, or Earth developing a climate of "boiling" oceans.
Which is why at least 97% of actual climate scientists categorically reject this particular brand of Hollywood anti-science fantasy.
And yes, one can be a member of the 97% who believe humans have a warming influence on climate, and yet, still completely reject the existence of this particular mythical CO2 unicorn.
Note: Temperature dataset; CO2 datasets. Excel was used to calculate 5-yr changes (ie. differences); and to produce plots and 6th order polynomials. To calculate a 5-yr. temp. change example: subtract the August 2009 temp. anomaly from the August 2104 anomaly. The same subtraction method used to calculate 5-yr. CO2 level (ppm) changes. Starting with January 1885, the 5-yr chg. calculations can be made for each subsequent month (GISS/NASA monthly dataset commences at January 1880).
Climate "scientists" on the government dole claim that CO2 emission regulation will allow bureaucrats to tweak the world's climate...thus, "scientists" will provide the world's governing class with a means to "dial in" the Earth's desired temperature with a CO2 "climate control" knob...but as it turns out, it's an indisputable shiteload of fantasy bordering on delusional.....
(click on chart to enlarge)
Delusional fantasies? Pretty strong stuff one might say.
Oh well, let's review just six actual climate science facts to make the case.
===>First, we know that these same scientists don't even know where over 50% of CO2 emissions disappear to...
===>Second, we know (and these same scientists know) that the global temperature change response to CO2 has declined significantly - opposite of the IPCC's "consensus expert" predictions...
===>Third, we know that these same scientists have been predicting rapid, continuous, accelerating dangerous global warming for decades but it hasn't happened...
===>Fourth, since it is agreed by 97% of all climate scientists that global warming has essentially stopped for 17+ years (only the fringe quacks disavow this), these same bureaucrat/academia scientists have come up with an overflowing cornucopia of reasons why, which reveal absolutely zero consensus...
===>Fifth, we know that the $billion$ super computer climate models used by these same scientists are fatally flawed, thus absolutely worthless regarding future global and regional climate predictions...
===>Finally, as this accompanying chart of the empirical evidence indicates, while the per cent change in cumulative CO2 emissions dropped in a quasi-continuous pattern since 1979, the RSS annual global temperatures anomalies instead follow an opposite increasing trend.
Simply put, all the above scientific evidence falsifies the entire concept of a CO2 "control knob" for the world's climate.
Yet these on-the-dole scientists keep promoting this delusional, all-powerful climate "knob" fantasy at the major expense of not only the taxpayer pockets, but also the gargantuan expense of sound climate policy-making being derailed from the track of common sense and rationality.
Ahh...those stubborn facts just always seem to muck up the climate delusional dreams and nightmares of so many knob-fanatics and control-freaks.
Note: From this multiple dataset, an estimate of total human CO2 emissions from 1751 to 2013 can be calculated. Since the RSS satellite monthly dataset only goes back to 1979, the chart plots the annual per cent change in cumulative CO2 emissions since 1979 (starting with the calculated cumulative emissions from 1751-1979). The RSS plot represents the 12-month (year-end) average anomalies. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
The climate science is indisputable...the known physics requires that each tonne of new CO2 emissions will have a smaller impact than the previous tonne...there is no escaping the actual logarithmic relationship between atmospheric CO2 and global warming.....
(click on to enlarge)
The known climate science of global warming is not a mystery. It is well documented climate physics that just about every scientist agrees with. And for the layperson, it's not terribly difficult to confirm.
3. A spreadsheet to make the necessary calculations and then plot the outcome.
These items were used to produce the adjacent chart. Five different time periods were chosen, then the warming (degree C) per CO2 tonne was calculated for each time period.
The resulting datapoints were then plotted and connected with a fitted trend (6th order).
Clearly, this actual climate science empirical evidence substantiates the known climate physics.
With this confirmation, one could assume that all warming since 1850 was due to human CO2 emissions, but then the logical conclusion is cast in concrete science - CO2's impact is shrinking towards zero, as observed, and likely will have even a smaller global warming impact in the future.
Note: The chart's fitted trend provides a sense of direction in the past but it has unreliable predictive qualities (if any). Why 1950-2013? Because the IPCC claims human CO2 is principal cause of warming since 1950. Why 1988-2013? Because in 1988, NASA's James Hansen testified that CO2 warming was accelerating and dangerous (it's been neither). Why 1997-2013? Because, it's been approximately 17 years with the 'paused' global warming. The 1850-2014 period assumes 17.5 gigatonnes of CO2 for first 7 months of 2014. Used 12-month HadCRUT averages to calculate deg/tonne.
For Democrats, green-fascists, liberals, leftists, progressives, socialists and all the various big government types, objective, non-agenda science is the enemy ... especially when it comes to climate science empirical evidence ... those stubborn facts can be sooo cruel.....

Adjacent are the top 5 reasons the global warming hysteria has failed.
They are called empirical evidence - datasets of temperature observations confirming there has been no statistically significant warming for over 15+ years.
The "consensus" "experts" and billion dollar computer climate models predicted that human CO2 emissions would generate accelerating, catastrophic global warming.
All politicians, bureaucrats and scientists are prone to ludicrous exaggerations, lame mistruths and outright lies as techniques to frighten and push the general public towards accepting an agenda...and leftists, socialists, marxists, progressives and liberals are really exceptional talents in this art of public deception...some very recent climate-liar examples:
"Climate change is the most consequential, urgent, sweeping collection of challenges we face" (Hillary Clinton)..."confronting climate change” is “a duty or responsibility laid down in scriptures" (John Kerry)...“Climate change is so much more consequential than ISIS ever was" (Leading Democrat consultant)...“we are not very far” from the point where climate change should be declared an international public health emergency" (UN's Christiana Figueres).....
(click on to enlarge)
Any political success that is achieved by deceit, hyperbole and hysteria always requires a sacrifice of the empirical evidence and unbiased science.
Yet it is scientific facts and methodologies that ultimately win...it follows that the public can only be mislead for so long.
Despite the extremist hyperbole and doomsday-cult scenario hysteria, the science of climate change is rather mundane, from a long-term view: it gets cold and, OMG!, then it gets hot, with some periods of in-between. Climate change is constantly in play; and humans can no more stop its chaotic version of ebbs and flows, let alone ever controlling a single cloud, thunderstorm, hurricane or tornado.
This chart, from the science journal New Scientist, is a prime exhibit of real-world scientific evidence that reveals how inconsequential today's climate change is compared to all previous climate change.
From the chart, it is clear that extreme climate change is a constant; there have been much higher and lower temperatures in the past; modern climate temperatures are not excessive in the least; and, the purported human-induced, "dangerous" modern temperature warming is only a fraction of past natural increases.
We say purported, because our existence is taking place during a global cooling phase (look at chart closely and note the pale blue areas) which is rather long-in-the-tooth, and at some point would normally rebound to warmer temperatures, just naturally. Indeed, the entire warming since the Little Ice Age is likely to be predominantly a natural response to the prior millenniums of extended cooling.
As the chart's inset clarifies, the modern warming since the end of 1949 has been very modest, being completely within the bounds of previous ancient and geological warmings that have been identified by empirical science.
And the "tipping point" warming has become even more modest during the 21st century:
The atmosphere has not experienced statistically significant warming since March 1996.
The oceans have not experienced statistically significant warming since August 1994.
The globe has not experienced statistically significant warming since November 1996.
Memo to GOP elites: Do not just passively accept the climate-liars' exaggerations, hyperbole and factual misrepresentations. The public wants the science facts; they want evidence that challenges the mindless, ludicrous fear-mongering. Crush the Democrats' hysteria with the real science; and denigrate their junk science predictions generated from the failed computer climate models. Facilitate the flow of scientific empirical evidence and debate - hmm...it's called educating the public, eh?
The 'climate panic' industry has long predicted that growth in atmospheric CO2 would produce rapid and dangerous global warming acceleration...but NASA's GISS climate research unit pretty much slams that alarmist myth to the mat with empirical evidence...
(click on chart to enlarge)
The CAGW global warming hypothesis is rather straightforward: increasing atmospheric CO2 would warm the world in an accelerating, out-of-control manner.
For the adjacent chart, that indeed would be the case, if we pretended the green curve represented global temperature and the red curve atmospheric CO2.
But it's just the opposite in reality.
As the chart depicts over 12 different time periods (all ending July 2014), reality is that while CO2 levels keep increasing over time, the long-term temperature warming trend (the red curve) is not rapidly accelerating towards a tipping point of climate catastrophe.
What about shorter-term? (Okay, okay we won't mention this inconvenient fact.)
Well, note the 3-year period mark. Over the last 3 years, the CO2 level has increased by 7ppm and the warming acceleration "spiked" at 3.8°C per century. To put that "acceleration" in historical context, during July 1915 the global warming trend had a real spike...a 15.4°C per century spike without any meaningful increase of CO2 over the prior 3 years.
Conclusion: It is clear from the NASA/GISS empirical evidence that warming acceleration trends are not highly correlated with ever greater atmospheric increases of CO2. The claimed CAGW impact from the growing accumulation of human CO2 emissions in the atmosphere appears to be temperature-trivial. From the evidence, one can also conclude that not even GISS can manufacture a temperature dataset that reveals runaway warming, let alone their fabled catastrophic "boiling oceans" prediction. Dang, those stubborn facts.
Note: Monthly GISS temperature dataset source. All chart time periods end as of July 2014. Used Excel to calculate trends utilizing the built-in slope function; plots created by Excel. Monthly CO2 levels estimated from a combination of source-1 and source-2. Interpreting the chart: for example, over the 60-year period ending July 2014, CO2 ppm increased by 86 and the GISS per century warming trend for the last 60 years was 1.3°C.
Obama and his ilk fervently believe the South Pole is melting, soon to drown America's coast lines with a rising sea level...or, maybe Democrats are just pathological liars determined to scare Americans into voting for even bigger government...regardless, both the scientists and satellites document how wrong the liberal-left-greens are.....
(click on graph to enlarge)
Science is based on research and empirical evidence, not on speculative guesses or those "likely" predictions from computer simulations.
Over the last few decades, the IPCC and its computer climate models have speculated that Antarctica was melting due to all the human CO2 emissions released into the atmosphere.
CO2 emissions that were producing accelerating and dangerous global warming that was being "amplified" across the South Pole.
Democrats, the mainstream media and green progressives have continuously repeated these flimsy, fear-mongering predictions as science "truth," representing the mythical "consensus." Yet, they conveniently ignore the actual hard empirical evidence and real scientific research that the American public has paid for.
Case in point:The South Pole
A brand new peer-reviewed research study conducted by MIT scientists confirm what NASA's satellites have documented (see adjacent chart) - Antarctica is cooling. Ahem...those inconvenient stubborn facts just hurt, no?
"By contrast, the eastern Antarctic and Antarctic plateau have cooled, primarily in summer, with warming over the Antarctic Peninsula [C3 Ed: approximately 4% of Antarctica land mass]...Moreover, sea-ice extent around Antarctica has modestly increased.....In other words, the authors find that most of the Antarctic continent has cooled, rather than just the Southern Ocean..."
Note: Chart plots and trends produced using Excel. South Pole temperature anomaly dataset source (since inception date used). CO2 dataset source.
CAGW alarmists can no longer deny the physics and the inconvenient climate empirical records...the feared trace gas CO2 is proving to be a toothless boogieman...tipping point global warming is off the agenda due to ever lower CO2 sensitivity.....
(click on graph to enlarge)
WUWT had a recent article regarding the continuous diminishing impact of CO2 on global temperatures.
The indisputable physics of climate science states that for every molecule of CO2 added to the atmosphere, that molecule will have a smaller impact than the one before it.
This diminishing return of CO2 is a well known logarithmic function, as described here.
This most recent article elaborates even further on the ever-sooner trivial CO2 influence, which the author summarizes in this manner:
===>"The committed Nations by their actions alone, whatever the costs they incurred to themselves, might only ever effect virtually undetectable reductions of World temperature. So it is clear that all the minor but extremely expensive attempts by the few convinced Western nations at the limitation of their own CO2 emissions will be inconsequential and futile."
A visualization of the diminishing CO2 impact is revealed by the adjacent top graph. Its plot is a simple ratio of total temperature change divided by atmospheric CO2 (ppm) change since January 1850.
As the graph clearly depicts, the ratio declines in the direction of zero as the growing total of added CO2 produces less and less global warming. Ergo, the climate's sensitivity to CO2 emission is shrinking, constantly.
The bottom graph is the same ratio but only for the shorter period, dating from January 1950 to June 2014. Obviously, the huge increase of atmospheric CO2 from the modern period's industrial/consumer engine has indeed produced a diminishing impact on global temperatures.
This is the empirical evidence that the IPCC and CAGW alarmists never want to talk about as it provides the proof that human CO2 emissions will not be causing massive climate calamities. Yes...those same scary catastrophes always being portrayed by the 97% "consensus" Hollywood science and the robustly gullible mainstream press.
Note: Using January 1850 as the base temperature anomaly and CO2 level month, the total change for both parameters was calculated for each subsequent month. Then for each subsequent month, the total temperature change from the base month was divided by the total CO2 ppm change - a ratio, maybe best described as the amount of temperature change produced by a molecule of CO2. The HadCRUT4 monthly global dataset was used for numerator calculations; denominator calculated from the combined CO2 datasets found here and here.
There's a dirty little secret about the major CO2 emission reductions Obama's EPA is proposing...cutting CO2 emissions will have an impact of just about squat on global temperatures and the EPA is hiding that inconvenient factoid.....
(click image to enlarge)
To the numbers:
===> The EPA is proposing a 30% reduction of power plant CO2 emissions from 2005 levels
===> The reductions are expected to reduce U.S. economic growth by some $2 trillion
===> Consumers of electricity can expect their rates to increase by 10% per year
===> The CO2 regulations will likely reduce employment by 600,000, plus make U.S. manufacturing (huge consumers of electricity) even less competitive
===> Finally, per an expert computer analysis of the CO2 reductions, based on the known physics of climate science, the expected global temperature increase by 2100AD will be smaller, by an immeasurable, undetectable, trivial 0.02 degree, and that's rounded up.
The chart tells the factual story.
The IPCC is predicting global temperatures to be about 16°C by 2100. And with the EPA reductions? They still expect global temperatures to be about 16 degrees (15.98°).
And if global temperatures exceed the IPCC prediction and climb to 18 or 20 degrees by 2100, what then will be the EPA reduction impact? Still squat, since the global temperature averted will not change from 0.02°C.
What could make this 'squat' result even more embarrassingly bad for Americans? The evil CO2 twins, China and India.
While the U.S. has reduced its emissions by 7% over the last 5 years, China and India have increased theirs a combined 32%. The EPA enforced CO2 reduction will not only make Americans poorer, any global warming reduction will be completely wiped out and vastly exceeded by other nation's (America's global competitors) huge CO2 increases.
Talk about freaking and amazingly stupid bureaucrats gone wild.
Even the progressive liberal New Republic recognizes the non-existent temperature impact of the Democrats' CO2 regulations on global warming:
"The goal of these regulations is not to stop global warming, but to prove to the international community that the U.S. is ready to pay additional costs to combat climate change."
To summarize: The Democratic Party and Obama are using EPA bureaucrats to deliver a meaningless symbolic "climate change" message to foreign elites, purposefully sacrificing and harming American labor, consumers and businesses. To top it off, Obama's regulations ultimately produces no climate benefit or global warming reduction.
A combination of fanatical green activists and wealthy crony-capitalists has produced a strong influence over the Obama administration and its climate policies/regulations ...Democrats in Congress have also been bought off...unfortunately for the American public, these corrupting motivations lead the government and bureaucrats down policy paths that ignore climate history and its science.....

"What's the weather tomorrow?" 'Been, there, done that'
"What will the climate be 10 years from now?" 'Been there, done that.'
Regardless of human activities and human CO2 emissions, the climate and weather have a strong, built-in natural rhythm that takes place, relentlessly.
The scientific evidence is unequivocal about this: the global climate repeats itself.
The adjacent chart plots the scientific empirical evidence - the globe naturally cycles through periods of extreme cooling and warming. And as the evidence reveals, the Obama/Kerry climate-porn duo exist during a period of cooling, not the extreme accelerating global warming that they claim.
For context, the chart extends back to the 1850s, with major peaks in the global warming trend identified with the president occupying the Oval Office at the time.
Note that the highest peaks (ie. dangerous and rapid global warming) took place prior to 1950 and the modern era's industrial/consumer CO2 emissions. Note also that after peaks were reached, the climate naturally repeated its cooling phase - every single freaking time.
And because presidents and Democrats during those times did not deny the natural cyclical peaks and valleys of the global climate, they did not end up making fools of themselves by claiming that CO2 'vapors' had given the world a fever from a runaway, tipping point warming.
By understanding the nature of the 'been there, done that' climate, past politicians did not hysterically succumb to the likes of today's anti-science charlatans advocating the deindustrialization of America, and the hypocritical snake-oil cronies wanting to steal from the American taxpayers' wallet.
Put another way, past politicians accepted those stubborn facts of empirical science, no matter how inconvenient.
Leftists, progressives, Democrats, liberals, socialists, crony-capitalists, communists, politicians, UN bureaucrats, crony-scientists, mainstream journalists and Hollywood celebrities are acknowledged as the world's climate-porn stars, as well as being in dire need of a basic manual titled 'Climate for Dummies'...their statements regarding global warming and climate change continue to be living proof that stuck-on-stupid and cluelessness are in a constant battle to dominate the leftward thinking brain.....
Without going through a complete litany of embarrassing and moronic left-wing climate change comments by the "elites," several from the past few weeks truly stand out:
===> "The planet is running a fever and there are no emergency rooms" - Democrat Senator Markey from Massachusetts
===>"We no longer need storms or hurricanes to produce flooding - it is becoming an everyday occurrence" - Anne Burchard, the Sierra Club
===> "It's kind of like telling a little girl who's trying to run across a busy street to catch a school bus to go for it, knowing there's a substantial chance that she'll be killed." - MIT professor Kerry Emanuel regarding critics of his opinion that catastrophic global warming disasters are today's climate
===> "It’s time for climate-change deniers to face reality’ – ‘They’re fiddling while the planet burns" - NY Daily News editorial page
===>"MSNBC segment claims that climate change could make a real ‘Sharknado’ happen" - a Comcast-owned Obama propaganda outlet
===>"And this, to me, is the most important film [Sharknado 2] ever made about climate change. There is no film, TV thing, special anything, more important than this film." - Actor, Judah Friedlander
===> "A new report says redheads might one day be extinct...when climate change brings an end to cool mist, the climate for red hair will also disappear." - Diane Sawyer, a TV "journalist", U.S. ABC News
===>"NYU Professor: Solve climate change by making people smaller" - S. Matthew Liao, instructor of bioethics at New York University
===>"Weather is not climate, you willfully ignorant fucksticks.” - obviously, the very "professional" CNN reporter, Bill Weir
Now, climate change comments like these have been part and parcel nonsense from the left-wing nutcases for over 100 years. As can be readily seen here, climate calamities are the 'forever' essential fear-mongering tactics used by elites and disaster-whσres to convince the public. (Additional crazed quotes from the "elites".)
More importantly, these common anti-science fear tactics are completely divorced from current climate science reality, as the empirical records demonstrate (here, here, here,here and here).
So, are the catastrophe rantings and hate emanating from liberal, progressive Democrats a result of some combination of incredible ignorance and stupendous stupidity regarding climate science?
If so, then maybe a book titled 'Climate for Dummies' would be a welcome science reading assignment for left-wing malnourished brains. Needless to say, said book should include a chapter on the science of temperature trends, made as simple as possible for those addicted to global warming calamity-porn.
Our contribution to the book will be the adjacent "Warming" Speedometer, which is a very simple visual aid to help liberal/progressive/Democrats put those really, really hard concepts of per century temperature trends into a proper context. (click on speedometer to enlarge)
For example, this simple decile infographic displays the entire range of 10-year global warming/cooling trends in per century terms since 1860. What could a climate-porn elite learn from this simple visual aid? (And help them from sounding like an uninformed idiot...)
the lowest per century trend (based on 120-month calculations) was reached during 1887
the highest per century trend was reached in 1983
the June 2014 per century trend falls into bottom half of deciles
the June 2014 trend is actually a global cooling trend
that some 31 years after the 1983 peak of 4.3°C warming trend, the temperature trend collapsed to a -0.1°C per century cooling trend.
Conclusions that a progressive/leftist elite might be able to reach from the simple "warming" speedometer of actual empirical evidence?
Hmm...let's see...that the approximate 1.5 trillion tonnes of human CO2 emissions (since the industrial age began) has not given Earth an accelerating fever that is causing the planet to burn - that's an unavoidable, rational and informed assessment of climate reality. And also that the world's modern climate, through June 2014, experienced a wide range of temperature trends (which are similar to the historical and ancient natural climate gyrations).
But as many have discovered to their dismay, empirical science means that liberal Democrats actually have to connect-the-dots, which apparently the climate-porn disorder prevents.
Note: Highest temperature trends (per century, based on 120-month calculations) for each decile noted on Speedometer (bottom decile also has lowest listed).

The IPCC's climate models have been noteworthy for their unfettered pattern of prediction failure, misleading policymakers and taxpayers alike regarding global warming...predictably, the pattern of failure continues in 2014.....
(click on graph to enlarge)
Multi-billions have been invested into climate science, with a special emphasis on climate models.
Despite the massive expenditures, the climate models utilized by the IPCC continue to be ginormous failures for the purpose of prediction.
The adjacent chart depicts this continuing pattern of failure by comparing the 3-year average of observed temperatures (HadCRUT4) versus the output of state-of-the-art CMIP5 models. The dataset plots reflect the most current values through June 2014.
The chart is also a testament to the unmitigated disaster of basing computer models almost exclusively on the influence of trace atmospheric gas CO2 instead of the natural climate cycles and oscillations that dominate the world of climate reality.
Climate change alarministas claim that modern human CO2 emissions are causing hotter temperatures around the world and the U.S...extreme global warming with blistering temperatures is their rallying cry but is it true?...Nope...it's another case of 'those stubborn facts'.....
(click on top or bottom chart to enlarge)
Of course, the CAGW argument has been (and continues to be) that huge CO2 emissions have produced extremely hot weather records during the 1980's, 90's and the 21st century, so far. But is it true?
Well, as pointed out earlier this year, the feared global warming is not producing the proclaimed hotter temperature records across the world.
And for the U.S.? NOAA confirms the same through June 2014. It is empirically true that the climate alarministas fear-mongering about record-setting extremes are without merit.
Case in point. This collection of charts depict NOAA's climate record frequency for maximum monthly temperatures across the contiguous U.S.
Figure #1 is the record of the 5% hottest months since 1980 in the U.S. Out of 409 months (34+ years), these 20 months represent the extreme. (The light blue data-points are the climate records since 1980 for all charts.)
Figure #2 is the 409-month record starting in 1920. These are the extreme 5% hottest months in the U.S. prior to the 1960s. (The dull red data-points are the climate records since 1920 for all charts.)
Figure #3 reveals that there have been zero months in the U.S. since 1980 that have had over 90 degree monthly averages. In contrast, the 1930's had two. In addition, for the period prior to 1980, there have been 57 months that averaged over 85 degrees while the period since 1980 there have been only 54.
Figure #4 plots the 60 hottest months for the two periods. Clearly, the pre-modern era produced hotter monthly records. These top 60 month plots represent the extreme 14.3% of each respective period.
For CO2 context, total global CO2 emissions are listed for each period (past and modern) on figures #1 and #2. The modern era emission tonnes are higher by a factor of 5+.
The evidence could not be clearer. Huge CO2 emissions, and higher atmospheric CO2 levels, do not correlate with a greater frequency of higher monthly maximum temperature records. This is indisputable.
Does this mean there won't be new record maximum temperatures set in the future? No, it does not. But, with that said, it is highly probable that future maximum records and their frequency have absolutely zero to do with greater CO2 emissions.

The frigid tropical hotspot continues to be a massive embarrassment to the CAGW faithful, and more importantly, the climate modelers...their prediction of a runaway tipping point in the atmosphere that would produce Venus-like temperatures is a classic example of herd-style failure by the consensus algorithms....
(click on chart to enlarge)
Two recent studies demonstrate the absolute futility of policymakers listening to climate modelers (and their billion dollar climate models) who continually predict climate calamities - a prediction record with zero successes.
The first peer reviewed study determines that today's climate models will never be able to predict the climate. Essentially, climate models assume linear climate relationships yet the real-world climate is non-linear and chaotic - defying intermediate and long-term predictive "expertise" with predictable regularity.
The second study clearly documents the abysmal prediction failure foisted on the public and politicians by the climate modelers. The climate models have long predicted a tropical hotspot in the atmosphere due to CO2 emissions; but actual scientific research reveals that the feared, mythical, runaway "tipping point" hotspot remains non-existent.
The hotspot tipping point, per the climate modelers, is supposedly in the process of turning Earth's atmosphere into a Venus replica, making Earth uninhabitable. But is that realistically happening?
The adjacent chart provides the indisputable, empirical evidence to answer that question unequivocally - NO!
The chart's red column is the Venus atmosphere's temperature at the 10km altitude. A conservative estimated temperature is still an incredibly hot 350°C.
In contrast, the chart's dark blueish columns show the Earth's atmosphere at the same altitude is an incredibly frigid temperature of minus 75C degrees. Yes, our tropical atmosphere is some 425 degrees colder.
Ahem....what freaking Venus-like tropical hotspot?! IT DOES NOT EXIST.
Of course, the climate moderlers stuck-on-stupid-Venus, don't mention this amazingly obvious climate fact. Instead, they focus on how Earth's tropical atomosphere is "accelerating" towards a Venus-like hotspot tipping point.
Accelerating? Barely creeping at a glacial pace would be more accurate.
Examine the chart closely. Since the beginning of the 1980's, humanity has poured some 860 billion CO2 tonnes into the atmosphere; atmospheric CO2 levels keep climbing (see yellow boxes); yet, the average tropical atmospheric temperature has essentially not budged (see red dotted baseline) over 3+ decades of modern consumer/industrial human emissions.
The solution to climate science reality and better policy? 'TRUST NO ONE CLIMATE MODEL' should be stamped on every CO2-centric climate model prediction and report that is handed to politicians and policymakers.
Then this type of anti-science insanity preached by the climate modelers would finally be D.O.A., never again to poison a public scientific debate with "runaway" catastrophic climate absurdities.
Note: Source of approximate 10km Venus temperature; source of approximate Earth's troposphere temperature; source of approximate tropical latitude troposphere temperatures; source of lower tropical atmosphere temperature change since 1979; source of total CO2 emission tonnes since 1979; source of peak CO2 ppm levels for each decade.
Depending on which climate alarmist "expert" you listen to, be it Al Gore, Tom Steyer, Obama, John Holdren or Michael Mann, each claims that the U.S. is suffering from CO2-caused extreme climate change...big problem though, NOAA empirical measurements of precipitation (snow and rainfall) prove those claims are nothing but blatant, political anti-science liesfalsehoods exaggerations.....
(click on chart to enlarge)
A prior 'C3' article documented the current normality of extreme drought across the globe.
With that said, the western U.S. is currently experiencing a very bad drought. If it's the start of another 200-year mega-drought, which plagued the area prior to the 1700's, there will be some very serious problems.
But for the entire U.S., NOAA reports that recent precipitation levels are normal - extreme high or low precipitation levels are not the norm.
The chart on the left is a plot of NOAA monthly measurements of precipitation since 1895, through June 2014. (NOAA dataset source) The black dots represent the moving 5-year (60-month) average of atmospheric CO2 levels.
The dark blue curve is the simple 60-month moving average of precipitation; the red line denotes the average monthly rainfall over the 1,434 months. As can be seen, the moving average is just about parked on top of the overall average - the declared current climate extremes purported by alarmists do not exist for the U.S.(nor for the globe as the prior article pointed out).
The total lack of precipitation extremes over the last 15+ years is completely counter to the CO2-based CAGW hypothesis that alarmists believe in fervently.
And what about other climate change "extremes" they hypothesize - well, the charts tell the real science story.
On this article's chart, the past extremes have been denoted (see color dots). Clearly, weather extremes can happen on a monthly basis, but they are rare, with no apparent association to CO2. Extended extreme precipitation levels over decades are literally non-existent in the NOAA climate record database.
Those Stubborn Facts: U.S. climate extremes of excess/minimal precipitation (rainfall and snow) are not evident in the recent climate record. The alarmist hypothesis that human CO2 causes modern precipitation extremes does not hold water, so to speak.
The latest research is conclusive, and confirms previous studies from multiple authors.
===>"The absence of trends in normalized disaster burden indicators appears to be largely consistent with the absence of trends in extreme weather events. This conclusion is more qualitative for the number of people killed. As a consequence, vulnerability is also largely stable over the period of analysis."
H/T: Roger Pielke Jr
For most CAGW skeptics, this finding is not a surprise since skeptics tend to be much more knowledgeable about past weather disasters. Previous weather disasters from the early 20th century were worse in many cases, and fully documented by the mainstream press at the time.
Conclusion: Recent weather events cannot be attributed to human CO2 emissions, nor the ongoing climate change that world is experiencing. In addition, modern climate change has not revealed itself to be "extreme." Thus, no correlation between disasters and the more recent non-extreme climate change.

Per the empirical measurement evidence published by NASA, the last 15 years of temperature change is not much different than earlier, pre-modern climate change...tepid to lukewarm is about the most alarmist description that fits the CO2 doomsday-cult hysteria.....
(click on chart to enlarge)
As almost everyone (alarmists and skeptics) agrees, climate change is continuous, accompanied by associated temperature changes. Based on the common measurement techniques utilized, over the last two decades the globe has warmed.
However, with that said, the last 15 years of global warming has really not been too impressive - so unimpressive, that scientists are debatingspeculating what happened to it.
In fact, when examining the moving 15-year temperature changes over the last two decades, the NASA research indicates (despite the gigantic modern human CO2 emissions) that pre-1950 global temperature changes were greater.
Yes, you read that right. When examining absolute 15-year changes in temperature, our modern warming doesn't quite measure-up to earlier warming.
The adjacent chart plots 15-year (180-month) absolute temperature changes (i.e. differences) of the two decades 1924-1944 (starting July 1924, ending June 1944); and plots the 180-month temperature changes of the two decades from July 1994 to June 2014.
As the chart indicates, both periods have similarities, but the greatest long-term global warming took place prior to 1950. The linear trends on the charts denote the continuing acceleration of 15-year warming (red straight line) for the pre-1950 era, versus the decelerating trend of our current times (green straight line), as reported by NASA scientists.
And, as can be observed, both the long-term warming and cooling extremes were greater during the pre-1950 decades. Confirming the pre-1950 weather/climate extremes is rather easy - just read the headlines from that era.
Conclusion: Modern climate and temperature change is somewhat tepid when compared to the natural extreme changes during the 1930s and 1940s. It would seem that human CO2 emissions are not causing unprecedented, accelerating extremes in modern weather and climate over recent 15-year spans, and may actually be dampening the extremes when compared to the past.
Note: The above chart is comparing the 2 decades ending June 1944 versus the 2 decades ending June 2014 - both periods exhibit identifiable warming.

'Climate Depot' recently highlighted a ludicrous NY Daily News editorial that is the typical fear-mongering pushed by establishment elites, eargerly published by the mainstream press in regards to global warming and climate change...the editorial's commentary of "while the planet is burning" is an opinion held by a bunch of spoiled, wealthy cronies who have served their country dishonorably by ruining the American dream for future generations and, btw, continue to propose self-serving polices that will make themselves even richer...hmmm..., or instead, maybe they really are just a bunch of scientific illiterate elites who can't be bothered with those inconvenient facts, no?.....
(click on images to enlarge)
As the above paragraph suggests, it's easy to throw out rhetorical bombast in response to over-the-top CAGW doomsday B.S. - especially if the bombast is directed at wealthy elites' galactically-sized hypocrisy and crony-capitalist climate change endeavors.
By now, per the recent polling of Americans (here and here), you'd guess that the GWNs would finally forsake the rhetorical excesses as being a spectacular failed public relations campaign, but apparently not, if the NY Daily News is any indication.
Putting the bombast aside, let's continue with the analysis of those inconvenient global warming and climate change facts.
Recently, 'C3' published a few articles about the actual temperature change experienced across the globe. The key word is 'change.'
When specific temperature 'change' is examined, does it exhibit characteristics deserving of the establishment elites' commonly used fear-mongering qualifiers? Those are qualifiers meant to scare purposefully, such as: accelerating, abrupt, unequivocal, irreversible, rapid, dangerous, indisputable, irrefutable, incontrovertible and etc. Or, as in the case of the wordy wordsmith elites at the NY Daily News, "while the planet burns."
The above chart on the left (Fig. A) is from this 'C3' article, which examines the 6-month absolute temperature changes derived from the state-of-the-art satellite measurement technology. Clearly, the empirical 6-month temperature changes since 1979 do not exhibit characteristics equal to the fear-monger qualifiers, let alone the hysterical, anti-science bullshît of "planet burning."
But wait.....what if the planet really was burning, per the elites' propaganda? What would accelerating, dangerous and unequivocal temperature change look like?
Well, that would be the fabricated 6-month change chart on the right (Fig. B). Using the same time period since 1979, the temperature changes plotted represent the simulated monthly temperature anomalies increasing every single month by just a tiny amount. As a result, the 6-month temperature change curve becomes a fevered-planet exponential.
That's the face of frightening global warming - an exponential precursor to the figurative "burning planet." But the real world intrudes as Fig. A is not that precursor - NOT EVEN CLOSE.
(Tip: If the actual climate temperatures ever produced a similar exponential 6-month, or a 36-month, a 60-month, a 120-month or a 180-month temperature change chart as Fig. B, then it's time for all good skeptics to move their petro-dollar funded haciendas to tropical Antarctica.)
Now, obviously, the two above charts look entirely different. And if the climate is producing accelerating, abrupt, unequivocal, irreversible, rapid, dangerous, indisputable, irrefutable and incontrovertible global warming (i.e. "planet burning") then the 6-month change chart on the right would be reality.
But the chart on the right is not reality - the chart on the left is, which presents a fairly constant up/down of temperature change, essentially negating opposing extremes. That's how the natural climate works in regards to both short-term and long-term temperature changes.
BTW, speaking of lack of extremes...to reinforce what climate reality truly is, depending on your preferred temperature dataset, there has been a non-extreme, slight global cooling trend, from a minimum of 9+ years to 17+ years . This is not some hidden science artifact that only the climate guru-clerics know about. This has been widely discussed in peer-reviewed journals and blogs for the last few years.
Despite the overwhelming empirical evidence, the establishment's elites and mainstream media continue to publish "burning planet" falsehoods. Being completely divorced from the known climate science facts has (thank goodness) seriously undercut their credibility and trustworthiness.
Conclusions: One, the world is not "burning," with all the empirical science pointing to a globe that is experiencing a very, very modest warmingcoolingwarming cooling. Two, "liar, liar, pants on fire" doesn't quite describe the anti-science, the anti-empirical denialism, the overall dishonesty and crony-malfeasance the elites and wealthy pursue to enrich themselves by impoverishing the rest of the world.
The over-the-top predictions of catastrophic climate disaster from proponents of CAGW have become a public relations disaster for the establishment science community...the constant hyperbole about extreme climate change due to abrupt, accelerating and unequivocal global warming turns out to be without empirical, scientific merit, as the UK's recognized gold-standard global temperature dataset confirms....
(click on image to enlarge)
The lack of major hurricanes making direct landfall on the continental U.S. over the last 8+ years is a classic example of extreme climate change not happening as predicted.
Now, add to that the complete disappearance of statistically significant global warming - for the UK's HadCRUT4 there has been no statistically significant warming since October 1996; and for the RSS global atmosphere dataset, it has been since November 1992 - and one then begins to wonder about the incompetence of elite science.
The absence of climate significant warming by itself pretty much confirms that extreme climate change is a non-issue, deserving little priority and resources.
But, there is another view of extreme climate change that can be examined to ascertain whether it has become a modern era problem or not. This can be accomplished by examining simple 10-year absolute change events for global temperatures, both positive and negative.
By identifying the largest 20 warming events and 20 largest cooling events since 1850, the most extreme 2% of temperature swings can be placed in chronological significance. (This identification is best done with the IPCC's gold-standard, the UK's HadCRUT4 monthly dataset, which stretches back to 1850.)
The charts above provide the identification of these extreme, outlier temperature swings. (The May 2014 HC4 dataset contains 1,973 monthly observations from which 1,853 moving 10-year absolute change calculations can be derived.)
As is evident from the empirical data, the vast majority of extreme temperature swings (both warming and cooling) occur prior to 1960. Also, the charts' purple linear trend lines indicate that the extremes are shrinking (getting smaller, if you prefer) over time.
Conclusion: Human CO2 emissions have not caused the predicted abrupt, accelerating and unequivocal global warming during the modern era, as all of the above scientific evidence attests. In addition, the lack of extreme climate change disasters and shrinking temperature swings, in relation to the past, actually indicate there may be an inverse relationship with growing CO2 emissions and atmospheric levels.
Now that would truly be mind-boggling, and help explain why "consensus" scientists are so befuddled and at a loss. Of course, stranger things have happened, such as the recent admission by consensus establishment science that they have been horribly wrong (for three decades, yikes!) about dietary cholesterol and saturated fat causing heart disease.
However, with all the above stated, this does not mean that climate change is not happening; that human activities have no influence on weather and climate; nor that global warming won't occur in the near future.
Note: UK's HadCRUT4 2014 satellite dataset used in Excel to calculate 10-year absolute (i.e. arithmetic difference) temperature changes and linear trends for above charts. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
Are humans turning Earth into another Venus, an inhabitable planet with temperatures hotter than your Weber grill on the 4th of July? Well...when the empirical dots are connected the scary Venus fate for Earth goes poof....
(click on chart to enlarge)
In a previous post, empirical observations documented the lack of both short-term and long-term warming of the atmosphere.
Another approach to assessing the atmosphere's temperature change is to examine the 10-year changes in the lower troposphere. The graph on the left plots such changes.
Using a satellite dataset that contains 426 monthly temperature measurements, 306 moving 10-year changes can be calculated. This graph plots those 306 data-points (the proverbial 'dots'), plus the cumulative growth in CO2 levels over the same period.
Visually, it is obvious the 10-year temperature changes were dominated by increasing values up till the early 2000's. After that, the 10-year changes decreased consistently, turning from positive to negative. The graph depicts the global atmosphere actually cooling over recent time.
The long increase in 10-year temperature change, and then its subsequent decrease, is confirmed by both the 3-year simple average curve (aqua) and the fitted trend curve (6th order polynomial).
The pale green curve (another fitted trend curve, 6th order) represents the unabated, relentless cumulative growth of atmospheric CO2 levels.
Conclusion: Earth is not turning into Venus. The experts' predictions that human CO2 emissions would turn Earth's atmosphere into a simmering Venus lookalike, resulting in "boiling" oceans, is now substantiated as a crackpot, global warming bogosity - pure anti-science alarmism that was promulgated by establishment science.
Does the above mean that Earth's atmosphere will never warm again? Nope, it will indeed continue to have phases of warming and cooling just as it did in the past, sans Venus conditions, though.....because that is what climates do, just naturally.
Note: RSS June 2014 satellite dataset used in Excel to calculate 10-year temperature changes. fitted trends and 3-year average in the above chart. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
The just releasedBP Statistical Review includes an updated historical record of CO2 emissions across the world, through 2013.
While China's CO2 emissions have almost tripled since the Kyoto Protocol of 1997, the U.S. emissions have decreased about 2%.
That U.S. reduction actually is superior to all the world's major regions and entities, as identified by the BP research report. This U.S. reduction (see adjacent chart) took place even though the U.S. was one of the few countries not to sign the 'Protocol.'
With that said, any CO2 emission reduction by the U.S. is being immediately offset by the huge increases happening in other parts of the world. As a result, neither U.S. citizens, nor the world's, are benefiting from any U.S. CO2 reduction efforts.
To make the U.S. CO2 reduction aspirations even more bleak, if America could slash its emissions by 50% for each of the next 85 years, the net impact on global temperatures by 2100AD, at best, might be all of a measly -0.09°C.
That type of impact would require U.S. emissions to drop by some 3 billion metric tonnes per year, which based on today's technology, would likely amount to at least an annual $1 trillion expense (assumes a ludicrously low $400 per tonne cost to immediately replace all the lost fossil fuel utilization, needed new infrastructure, replacement transportation vehicles and g*d knows what else to survive).
Whether its impact is viewed from a short-term or long-term perspective, the CO2 trace gas has had little, if any, influence on the atmosphere's temperatures...satellite measurements provide the proof that the CO2-causes-global-warming hypothesis is not climate reality..... (follow up article is here)
(click on chart to enlarge)
It has been predicted by the climate "experts" that human CO2 emissions would cause the world's atmosphere to warm dangerously, producing catastrophic, world-ending climate disasters.
Some 30+ years later, the advanced satellites circling the globe, 24/7, provide the empirical evidence that the "expert" predictions were of no substance, nor merit.
The adjoining graph is a plot of short-term temperature changes since 1979, along with the cumulative growth of atmospheric CO2 levels. Specifically, the 6-month temperature changes show little, if any, impact from the continuous growth of the atmospheric trace gas, CO2. [Clarification: chart's temperature plot is a moving, full 6-month temperature difference calculated from global RSS monthly anomalies, currently 426 anomalies in dataset]
In fact, the overall trend (aqua line) of 6-month changes is actually negative - an indication that abrupt, accelerating dangerous global warming of the atmosphere is non-existent. [Clarification: Aqua line is a linear trend produced by Excel]
Now, that is the short-term. What about the long-term?
A recent study by a group of pro-catastrophic global warming scientists1 determined that the human CO2 warming influence on atmosphere temperatures would be obvious over 17-years of satellite measurements. These are the scientists who claim we have experienced catastrophic global warming, with world climate disasters being imminent.
And what has happened, over this long-term span specified by these scientists?
Over the last 204 months (that's 17 years through June 2014), the atmosphere temperatures have actually exhibited a global cooling trend, not warming. The per century trend is only a -0.36°C. Despite this small number, it still represents a cooling trend, opposite of consensus predictions.
Whether short or long-term, the state-of-the-art empirical satellite evidence is not only obvious, it is both climate and statistically significant: CO2 emissions have not had a significant influence (warming or cooling) on atmospheric temperatures.For objective science, this means that the CO2-centric anthropogenic global warming hypothesis is essentially invalidated, as it is currently understood.

Previously, using NOAA climate records, past U.S. warming (“global”) in the U.S. was compared to the modern U.S. warming...both warming periods were essentially the same despite the massive human CO2 emissions during the modern era…now an analysis of NOAA global temperatures reveals the same outcome…ah, those stubborn facts.....
(click on chart to enlarge)
The gigantic consumer/industrial CO2 emissions during the modern era are claimed by “consensus” climate scientists to have caused rapid, accelerating, unprecedented dangerous warming, never experienced by humans before. But is this claim really true? Does climate reality support the catastrophic climate change hyperbole?
Nope. But you be the judge.
If CO2 emissions really matter, then their impact should be robustly apparent when analyzing long-term 5-year global climate warming averages. Simply stated, the differential impact from the gargantuan, modern CO2 emissions on global 5-year average warming should be significantly greater than pre-modern, natural warming for 5-year averages.
But that’s not the climate reality. Surprised?
As the adjacent graph of NOAA empirical evidence (5-year averages) reveals, the alarmists’ hyperbolic claims are without any scientific merit. The amount of modern warming (red dots) is nearly identical to the earlier 20th century warming (blue dots) that took place in the absence of large CO2 emissions.
In fact, the 381-month periods plotted in the graph have the earlier period warming to be just slightly higher (+0.01°C) than the modern warming.
To simplify, that’s totally contrary to what the UN’ IPCC and the major US and UK climate agencies have claimed and still widely promulgate.
For those more interested in the details of the chart’s plots, we move to a more complete description below…to the details!
Why was a 381-month (31.75 years) period chosen? Simple. Prior to 1950, the 5-year moving average of global temperatures peaked during October 1944. That peak was reached over a span of 381 months, from the starting trough low point of the 5-year average that occurred during February 1913. Voila, 381 months.
The modern 5-year average peak happened during January 2007. Working backwards to create a similar 381-month span, the start month for the modern period span is May 1975.
In order to produce a visual apple-to-apple comparison of the amount of warming for the two periods, the prior period’s 5-year averages were offset to start at the exactly same point as the modern warming period (‘offsetting’ the datapoints does not affect the slope of the earlier period’s warming trend, nor the amount of warming).
Although it is difficult to discern visually, as stated before, the earlier (pre-1950) 20th century warming actually was higher – a miniscule +0.01 degree higher, but still higher. That’s a freaking amazing outcome since all “experts” claim the modern era global warming was “unprecedented” and “unnatural.”
So what happens when the period span is changed to 300 months (25 years), using the same peak months as before (October 1944 and January 2007)?
It swings in favor of the modern span of warming – by incredibly the same amount of +0.01°C.
And if we used a 35-year comparison instead? OMG, modern warming just went berserk, clocking an unbelievable, higher modern warming of…wait for it…+0.07°C degree. (/sarc off)
And what if the comparison’s NOAA-benchmark was the trough-to-peak warming span of November 1976 to January 2007, a 363-month span (30.25 years)? Compared to a similar 363-month period, working backwards from October 1944, the modern warming was only +0.06°C higher, which is smaller than the error bars of a standard thermometer measurement.
Yep, no matter how one slices and dices the 5-year average warming amounts, the modern era’s warming represents an increase not even one-tenth of a degree greater than the pre-1950 warming – it is not only a statistically worthless difference, it is completely climate insignificant.
What’s the essential point here?
Those stubborn facts: Well, the amount of trough-to-peak modern warming is almost identical to the amount of pre-1950 trough-to-peak warming, which is clear indication that the modern warming was likely due to the same natural influences, regardless of the amount of human CO2 emissions.
Certainly, one can’t conclude that CO2 does not have some role during warming periods, but NOAA’s empirical science research indicates it is ‘best practice’ science to conclude that the vast majority of modern warming was a result of non-human reasons.
As wise old people would say: “it’s the same old, same old.”

This is also true for the continental U.S. temperatures during the 21st century, though, with an obvious difference. As the adjacent chart reveals, the U.S. temperatures exhibit an actual cooling trend - actually opposite of the rapid, dangerous, "scorching" climate that the White House and some propagandistsliars journalists report.
Based on moving 5-year averages of U.S. monthly temperature anomalies, America's continental climate is currently cooling at a minus 1.2°F per century rate.
It's just another case of 'those stubborn facts' being mighty inconvenient.

Mother Jones magazine and Chris Mooney provide further proof that the alarmism of greens and the fringe left/progressive/liberal extreme of American politics is a cornucopia of anti-science, falsehoods and misrepresentation...Catastrophic Global Warming Derangement Syndrome (CGWDS) victims have become a national embarrassment and tragedy, no?.....
(click on top images left #1 & right #2 to enlarge)
(click on bottom images left #3 & right #4 to enlarge)
Actual climate science and empirical evidence has long been the enemy of the green/left/Democrat consortium being funded by Obama's crony-donor billionaire friends. A classic example of their littering the editing floor with scientific truth can be found in this recentMother Jones article.
The top/left 'image #1' comes straight from the 'MJ' article and it immediately sets off one's B.S. detector.
Vast portions of the U.S. have just made it through a brutal winter and a cold, wet spring, yet Mother Jones is talking global warming "scorching"? In fact, after 30 years of gigantic CO2 emissions, the first four months of 2014 temperatures in the U.S. were, on average, -0.26 degree lower than those of January, February, March and April during 1984.
Yep, 30 years later the U.S. was cooler - as pseudo-journalist Chris Mooney would say: "It's about our scarcely recognizable present"
In determining where this Mother Jones pile of B.S. was leading, a closer scrutiny of the 'image #1' reveals that it is a temperature map for the last 22 years.
Whoa, 22 years!? WTF?
Honestly, what objective, impartial person interested in the empirical-based science would pick a 22-year snapshot as the sole climate representation of the U.S. with no other context? What major publication would publish such a temperature map without at least also showing what has happened to U.S temperatures since 1996?
Can you quickly say "amazingly, ludicrous, cherry-picking misinformation" three times in a row? It's safe to say Chris Mooney and Mother Jones can.
So, what would cause those brainy "elites," who suffer from an obvious CGWDS affliction, to basically misrepresent the climate as it is being experienced today, but instead focus on a specific 22-year period? Why not present the readers with multiple-period maps and graphs that provides a contextual full picture of reality?
Well, image #2 (top/right) provides the ready answer to their ludicrous cherry-picking deception.
Turns out that the 22-year period ending March 2014 had the highest per century rate of U.S. warming when analyzing multiple time periods. Yet, as the American public is well aware, the previous U.S. warming trend that generated that unique 22-year peak has since morphed into a cooling phase since 1996 - ahem...now look at all those negative blue bars in image #2 starting with the last 18 years.
Adding even more proof that the U.S. is not suffering from "scorching" global warming deception, images #3 and #4 reveal NOAA's climate reality for 1992 (22 years ago) and 2014, respectively.
How about that! NOAA, the principal U.S. climate research agency, reports that the U.S. recently experienced an actual cooler climate than that of 1992 (22 years ago).
Gee, why would Chris Mooney and Mother Jones leave important empirical evidence context like this out of their "scorching" article? Hmmm...makes one wonder if they purposefully want their readers to think they are liars; or maybe they think the readers of 'MJ' are just incredibly gullible and/or common sense stupid. Who knows?
For additional scientific context missing in the Mooney climate-doomsday article, go here, here, here, here and here.
Oh...and those "Seven Scary Facts About The Global Left & Greens":
1. they start with the initial bullshÎt;
2. then they sprinkle some more bullshÎt here and there and everywhere;
3. they advance their agenda by rapidly accelerating the bullshÎt spreading with over-the-top hyperbole;
4. they then deny their bullshÎttÎng when all the scary predictions fail;
5. then they claim they were misunderstood and really did not mean their previous bullshÎt to be literal;
6. they then introduce multiple new theories as to why some new bullshÎt should be believed, ignoring the fact all their previous bullshÎt was completely wrong;
and #7, hey, they finally state that you're a racist, Gaia-hating, homophobic, paid-by-the-Koch-brothers denier if you no longer believe all of their anti-science, doomsday bullshÎt.
Indeed, it's never ending CGWDS bullshÎt combined with crazy-person denial - similar to the famed Black Knight's relentless denial, despite his obvious and indisputable shortcomings.
The huge failure of "expert" climate science goes all the way back to the IPCC's genesis: its 1990 predictions provide the 99.9% proof that their global warming fear-mongering is without scientific merit.....
(click on chart to enlarge)
Climate reality and actual evidence-based science has completely eviscerated the global warming claims of the IPCC's "scientists" and those in the "consensus" choir.
Recent climate change predictions produced by the latest bleeding-edge computer models have proven to be spectacularly wrong.
Longer-term proof that the IPCC (and its climate-doomsday religion acolytes) is provided by the original "expert" predictions that were first published back in 1990. That proof is clearly obvious from the accompanying chart.
Simply stated: the IPCC predicted that if human emissions of CO2 kept growing in a business-as-usual (BAU) manner, the world would experience a high likelihood of global warming acceleration - to a per century rate of 2.8°C.
Instead, as the chart depicts, global warming since 1990 has achieved only a 1.4°C per century rate, per the global-wide 24/7 measurements of satellites. Yet the BAU growth of human emission tonnes actually accelerated to a 13.2% annual rate for the 10 years ending 2013. Those are the stubborn facts that are indisputable, unequivocal and irrefutable.
This cataclysmic failure of orthodoxy, green religion-based, climate-science-doomsday predictions is now being referred to as one of science's biggest mysteries - a confirmation of 99.9% proof one could surmise, and the public reportedly agrees with.
And let's not forget the proof that the doomsday climate scientists are confirming their own spectacular prediction failures with the recent plethora of excuses.
Whether the "experts" are the IPCC's climate models or associated scientists, their climate predictions for Northern Hemisphere snow extent, i.e., square kilometer coverage, have been robustly wrong...
(click on chart to enlarge)
The IPCC has become globally infamous for their atrocious climate change, global warming predictions (read brief summary).
There are multiple examples of the up-to-date empirical evidence confirming that the IPCC's doomsday climate predictions are without merit - here, here, here and here are just a few examples.
And at the close of March 2014, it is now possible to compare the latest empirical evidence versus the IPCC "expert" prediction that human CO2 emissions would severely reduce snow coverage across the Northern Hemisphere during winter months (December, January, February and March).
As this accompanying chart obviously indicates, snow extent has actually increased over the short term (see 3-year average curve); and since the beginning of the dataset, winter snows have ranged within a narrow band.
During any given year's winter, there are periods of extremely large snow extent, soon to be followed by low extremes. This natural variation occurs despite the growing surge of CO2 emissions, as denoted by the methodically increasing black step-curve.
For many regions of the Northern Hemisphere, the past several winters since 2007 have witnessed brutal winters of extreme snow and cold, which the upsurge of the chart's 3-year average curve corroborates. As additional corraboration, there is the actual global sea ice growth that also mocks the "expert" IPCC predictions.

Latest peer reviewed research determines that recent sea level rise along the coasts of northern Europe and the English Channel are within historical bounds experienced during the 19th and earlier 20th century periods.
Per the scientists from Australia, France, Germany, the Netherlands and the United Kingdom, the actual empirical evidence points to a potential sea level rise by 2050 AD of 2.1 inches for the North Sea coast and 1.6 inches for the English Channel.
"In light of the findings of the international team of scientists participating in this significant study, it would appear that there is nothing unusual, unnatural or unprecedented about the rate of sea level rise throughout both the North Sea and the rest of the Global Ocean over the entire CO2-emitting course of the Industrial Revolution."
In summary, this study does not support the irrational, unsubstantiated current claims and predictions of sea level increases made by prominent GWN's who rely on projections from the discredited climate models. The recent and past sea level increase facts reveal the totally absurd and irresponsible, anti-science speculations of 36 to 120 inch rise for coastal waters.
What happens when you compare the empirical evidence of climate reality versus the predictions of government-funded climate models?.....how do you spell Q-U-A-C-K....
(click on chart to enlarge)
One does not have to be a rocket scientist to recognize the global warming prediction quackery that constantly flows from the taxpayer-funded, government sanctioned, computer climate models.
The adjacent chart, produced by a non-rocket scientist, is yet more proof of the quack climate model "science" that policymakers have been forced to rely on. Charitably, policymakers would make better decisions if instead they relied on flipping a coin or a visit to their local astrologer with a crystal ball.
The chart specifically compares state-of-the-art climate model temperature output for the U.S. corn belt region versus NOAA's climate network system (USHCN).
Simply put, climate models don't do reality, since forever.
Amazingly, over the shorter term, the global warming predictions for the U.S. breadbasket have been even worse, in fact, astoundingly atrocious - instead of warming, growing areas have cooled considerably.
Solution: Until climate models are verified as being capable of somewhat accurate forecasts (predictions, scenarios, etc.), policymakers and taxpayers should completely ignore any climate simulation output that is a result of today's computer models. This should also apply to mainstream journalists, but, let's be honest here, they're too incredibly lazy and gullible to distinguish between empirical evidence and agenda-driven prediction fantasies, no?
The distinctive global warmings during the modern era and the Medieval Period share similar causes - our solar system's sun, per China's climate scholars...
(click on image to enlarge)
Researchers around the globe continue to build on the mountain of scientific evidence that the Medieval Period had warmer temperatures than the modern era.
And the evidence for a powerful solar influence on temperatures and climate change is substantial and growing.
====> "Here we present[Editor: Chinese scientists] decadally-resolved, alkenone-based, temperature records from two lakes on the northern Tibetan Plateau. Characterized by marked temperature variability, our records provide evidence that temperatures during the MWP were slightly higher than the modern period in this region. Further, our temperature reconstructions, within age uncertainty, can be well correlated with solar irradiance changes, suggesting a possible link between solar forcing and natural climate variability, at least on the northern Tibetan Plateau."
Ahhh.....those stubborn facts. The "consensus" climate science "experts" have been constantly bedeviled by the empirical climate reality, such as this...
(click on chart to enlarge)
NOAA's empirical evidence does not lie, nor deny. Over the last 205 months (Feb. 1, 1997 thru Feb. 28, 2014), the continental U.S. has cooled at a per century rate of -0.96°C.
This has taken place despite the assurance of almost every taxpayer-funded climate scientist that the exact opposite would happen.
They told us that their powerful and sophisticated computer climate models could accurately predict what future climate conditions we would experience.
Except they were spectacularly wrong from day one; and yet, they kept spending multi-billions of taxpayer funds by throwing it down this failed climate research rabbit hole.
Why were the "experts" and the computer simulations so, so wrong?
From a recent essay about this gigantic and embarrassing failure by government scientists, we learn:
"Realities about climate models are much more prosaic. They don’t and can’t work because data, knowledge of atmospheric, oceanographic, and extraterrestrial mechanisms, and computer capacity are all totally inadequate. Computer climate models are a waste of time and money...Inadequacies are confirmed by the complete failure of all forecasts, predictions, projections, prognostications, or whatever they call them."
On average, it's been estimated that a plastic bag weighs 32.5 grams (for the record, a typical grocery store plastic bag weighs only 5 grams). And its been estimated that a plastic bag at the average weight represents about 200 grams of CO2 (when accounting for the plastic bag's production and eventual incineration).
As a result, via simple multiplication, those 100 billion plastic bags equal 20 trillion grams of CO2, which converts to 20 million metric tonnes of CO2.
Sooo.....what's the plastic bag impact on global warming from 20 million tonnes/year of CO2 over the next 20 years?
Well, it's squat, too. There is no warming impact, which makes the Democrats' claim more anti-science propaganda of the quackery sort.
Banning plastic bags due to their climate change impact is sheer nonsense, but banning them for other environmental reasons is a whole 'nuther issue.
The global warming impact calculation can be accomplished with the 'C3' simple estimator found here and just enter the CO2 tonnes amount desired. (Note: The image above is only a replica of the real tool.)
For comparison purposes, the 'C3' estimator replica above also reveals what would happen to "global warming" if the entire U.S. economy shuts down for one year, eliminating some 5.8 billion tonnes of CO2 emissions from fossil fuel combustion - again, it's a global warming nothing-burger.
These smiling Democrat senators recently held a "climate change" sleepover at the Capitol that was a rather blatant attempt to please their billionaire-crony donors.
Instead of accomplishing anything meaningful, the low-watt Democrats justifiably received a heavy round of mockery from all sorts of Americans.
The Democrats' climate science has now been in quack mode for an extended period.
An example of the economic harm imposed by this type of anti-science quackery was a legislative victory for the Democrat-controlled U.S. Senate during 2007 when the "Energy Independence and Security Act" was passed. This 'Act' effectively banned the future purchase of incandescent light bulbs by Americans.
Since the beginning of 2014, those desired, cheap light bulbs have been difficult to find. And it's completely due to the quack anti-science that Democrats believe.
This fanatical belief had them convinced that America's light bulbs were causing global warming, and the only way to save the planet was to declare war on Americans favorite lighting source.
Thus, they have forced every American to buy more expensive lighting replacements instead of the old, reliably pleasing and inexpensive incandescent technology.
Democrats did this in the name of "science." But as was the case with their recent anti-science climate-pajama party, factual science was pretty much AWOL in the war on light bulbs.
So, what does the indisputable, factual science tell us about the global warming impact of keeping incandescent light bulbs out of the hands of Americans?
Simply put: It is squat - there is zero impact by doing so.
The science is actually pretty straightforward. First, Americans buy some 2 billion bulbs per year. Per the EPA, if each incandescent bulb purchased were replaced instead with an energy efficient CFL bulb purchase, it would reduce CO2 emissions by 0.0382 metric tonnes. So, two billion bulbs per year times 0.0382 tonnes totals to a yearly CO2 reduction of 76,400,000 tonnes.
Sounds impressive, no?
Well, in the scheme of things that are climate significant, it's not. As the real science dictates, by the end of the next 20 years the yearly CO2 reduction of 76 million plus tonnes will have zero impact on global temperatures. (And that's to the second decimal place.)
Let's do the math (or you can just use this 'C3' estimator whose replica is displayed below the Democrats' photo-op image): We know from the empirical evidence that since 1850 the Earth has warmed a +0.85 Celsius degree while humans have emitted approximately 1.4 trillion tonnes of CO2. As a result, to warm the Earth +0.01°C about 16.5 billion tonnes of human new CO2 emissions would be required.
How's that figure compare to the tonnes saved over 20 years by replacing 40 billion light bulbs? (BTW, it's highly likely there a lot fewer than 40 billion to be replaced.) All those incandescent light bulb CO2 savings would amount to only one-tenth the required 16+ billion tonnes.
And that then means all the CO2 savings would amount to no measurable global temperature impact. Hmmm...did we say 'squat' yet?
Just to add the appropriate emphasis to what the past 164 years of empirical science tell us, the 'C3' estimator replica above also reveals what would happen to "global warming" if the entire U.S. economy shuts down for one year, eliminating some 5.8 billion tonnes of CO2 emissions from fossil fuel combustion - again, it's a nothing-significant outcome for the climate.
That's a climate factcheck.
Unfortunately, despite this real climate science, Democrats will continue to demagogue the climate change issue for their billionaire donor-cronies, based entirely on the quack anti-science position that reducing current U.S. CO2 emissions would actually accomplish anything of climate-impact substance.
Per NOAA's published annual mean temperatures, the modern warming trend for the U.S., since the beginning of 1950, amounts to an increase of 1.35°C by century end.
But this modern trend is just +0.36° higher than the trend that existed from 1895 to 1949. For the records, that existing pre-consumer/industrial CO2 trend was already at a significant +0.99°C, by year 2100.
Based on the official climate empirical evidence, as the adjacent chart depicts, this recent measly trend increase (a third of a single degree) of climate change (i.e. U.S. warming) is claimed by IPCC scientists to be a result of the modern, gigantic global emissions approximating over 1.2 trillion tonnes since the end of 1949
Yet, the prior period to the modern era experienced a climate change trend that was equivalent to a 1-degree change. Essentially, a built-in, long-term trend some 3-times larger than the additional modern trend increase.
And this larger, pre-modern, in-the-pipeline warming trend took place when human CO2 emissions were a fraction of the modern era's - literally, one-tenth the amount of emissions (see chart).
Then there is the whole embarrassing issue of the great climate science mystery, which includes the U.S. climate records. During the last 17 years that span from February 1997 through February 2014, the continental U.S. actually cooled at a per century rate of -1.0°C (per NOAA's monthly anomalies).
Now what does all this empirical evidence mean?
Well, obviously, the pre-1950 climate change was significantly greater than that of the modern era. Again, obviously, the modern U.S. climate change has been way over-hyped by politicians and government scientists when put into a historical perspective, as above.
Then there is the indisputable NOAA fact that the last 17 years have witnessed a general cooling for the U.S., which, obviously, is at substantial odds with the "consensus" climate scientists predictions and the IPCC's "expert" computer models.
When combining all this very obvious evidence, one can fairly surmise that either global warming is not very "global" or that human CO2 emissions are not a very powerful influence on the Earth's climate or institutional, orthodoxy climate science has failed, badly - or maybe it's a lot of all three.
"Consensus" scientists have responded by producing multiple speculative reasons as to why the disappearance of global warming has occurred, without any convincing success.
In contrast, objective researchers have chosen to reexamine the actual empirical measurement evidence to determine if the "consensus" estimate was realistic, and if not, what a more accurate estimate would be for climate sensitivity.
As this article describes, new scientific studies have recently been published, strongly indicating that both a long-term and short-term sensitivities are significantly lower than the failed assumptions of the IPCC.
The new research, depending on the time-frame chosen, indicates empirically-based climate sensitivity ranging from +1.0°C to +2.9°C.
Using the above 'C3' tool to estimate different global warming outcomes dependent of climate sensitivity chosen, it can be determined that if this century's climate sensitivity is closer to the '+1.5' the new studies suggest, then the global temperature impact would be a very modest +0.52°C - clearly, not the over-the-top +6 or more degree possibilities tossed about by many "consensus" scientists.

An analysis of satellite temperature dataset, through February 2014, identifies only two 5-year periods having significant warming and five periods that exhibit either zero warming or cooling.....the consensus experts' predicted reaction, by the climate, to a surge of human CO2 emissions is not supported by empirical evidence
(click on chart to enlarge)
The adjacent chart clearly depicts the lack of the predicted global warming since the decade of the 1990s.
Utilizing a straight-forward, empirical analysis of the RSS satellite temperature dataset reveals a rather tenuous (non-existent?) relationship between global atmospheric warming and CO2 emissions.
As the chart suggests, a brief global warming spike has morphed into an extended global cooling phase, which the consensus experts have identified as 'the mysterious global-warming hiatus'; plus being forced to trot-out a wild variety of excuses as to why their AGW predictions have failed.
Unfortunately, the GWNs, and their compatriots in the green climate-doomsday-is-near cult, continue to reject the actual scientific empirical evidence, such as the above chart.

Another new study by climate "experts" produces even more speculation as to why the modern global warming 'Pause' has unexpectedly happened ... in the meantime, per NOAA.......
(click on chart to enlarge)
(click on chart to enlarge)
The never predicted 'Pause' has no equal as the chart on the left begins to suggest. This chart is a plot of total temperature anomaly differences (i.e. total monthly change, month by month) since February 1998 through December 2013.
NOAA's year-end 2013 published monthly temperature dataset has identified February 1998 as the highest temperature anomaly month ever. And as the chart indicates, for the subsequent 190 months, that 1998 peak was never topped, despite an average 29.5 billion new tons of CO2 emissions per year over that time span.
Since the modern era beginning with the 1950s, that 190-month stretch is the longest uninterrupted "pause" - simply, this is unprecedented since the era of vast consumer/industrial CO2 emissions commenced.
In contrast, the earlier 190-month period ending February 1998 experienced an almost continuous climb of higher and higher temperature changes, culminating in the early 1998 peak.
This steady climb was supposedly the sole result of the growth of new CO2 emissions (this periods emissions actually averaged some 30% less than the subsequent 190-month period ending in 2013).
Thinking the pre-1998 warming phase was of permanent nature, not transient, the consensus climate "experts," and their sophisticated climate models, predicted this steady warming trend would just drone on year after year, as far as the mind could speculate.
And like so many experts in so many other science fields, the IPCC climate wonks were wrong, spectacularly. It now stands at 190 months of prediction failure!
Surprised? If yes, review previous of 'those-stubborn-facts' charts here and here.
Note: How calculations were done: For the 190 months ending December 2013 (left chart), the February 1998 anomaly was the base point. The anomaly difference from this base was calculated for each subsequent month. No calculated difference during the 190 months was greater than -0.0001. Similar difference calculations were made for the 190-month period ending February 1998 (see rightmost chart), with that period's base point being April 1982.

Proponents of the CAGW gloom and doom disaster scenarios often say that we need to "connect the dots" to understand how CO2 emissions are causing dangerous "accelerated" global warming.
Of course, these alarmists hope no one will actually "connect the dots," which is the almost guaranteed case for mainstream science journalists, TV pundits, politicians and Hollywood celebrities - those icons of mental laziness and politically correct thinking.
But what happens when one does actually connect-the-dots?
Well, the real world climate reality is then discovered: global warming has stalled and global cooling trends are appearing (see the UK and the US), confirmed by the scientific empirical evidence.
This adjacent chart for the global temperature trends (using the HC4 temperature dataset published by the UK's premier climate research agency) provides compelling evidence that human CO2 emissions are not producing disastrous global warming trends.
As the chart reveals, today's per century trends are dominated by cooling for the different time periods; today's trends are multiple times below prior period, historical highs; the 5, 8 and 10-year trends are definitely below the average modern trend (1950 through 2013); and all the trends are significantly less than those reached 15 years ago (see black dotted lines for year-end 1998 trend levels).
As an aside, in the future, as the 15-year trend moves further and further from the persistent temperature impacts of 1997 and 1998, it too will likely become a negative trend.
None of today's trends even approach the IPCC's predicted trend range of 2 to 6 degrees (C) per century that its "experts" and climate models told us long ago were being experienced (unfortunately, they mistook the natural climate's super El Niño's huge impact during 1997/98 as confirmation of CO2-induced warming).
As readily apparent, because of natural climate feedback forces, yesterday's over-hyped accelerated warming (eg, 1998) can quickly reverse course, delivering robust deceleration and even global cooling.
And that's what one learns from the empirical climate science when the "dots" are truly connected.
More of that connect-the-dot style of climate science reality: modern global and regional temperature charts.

Over recent decades, there have been many false claims, misrepresentations and untruths regarding climate change and global warming.
Unfortunately, these deceptions are commonly void of any empirical merit, pernicious in nature and stubbornly deep-seated, often held dear by the world's establishment elites. Typical of false claims held dear include: global warming is "accelerating"; "runaway" global warming is at a "tipping point"; and that the greenhouse gas CO2 is a "control knob" or "thermostat" for Earth's climate.
With an air of authority and trust, agenda-driven, white-coat scientists can make these fictions sound entirely plausible, especially to the incredibly gullible establishment elites. However, these falsehoods rarely can survive even the simplest climate 'factchecks,' which apparently are beyond the intellectual capabilities of most elites.
Case in point, examine the accompanying chart carefully. (click on to enlarge)
Using the UK's HadCRUT4 global temperature dataset and NOAA's datasets for CO2, one can plot the per century warming/cooling trends on a monthly basis going back to 1850. Utilizing the easy-to-use plotting and calculation tools of Microsoft's Excel, it is simple to compare the empirical temperature trends of climate reality with the growth of atmospheric CO2 levels.
What do these empirical climate records actually reveal?
===> That acceleration of cooling and warming happen with great frequency, then always followed with an inevitable deceleration - "accelerating" warming (nor cooling) persists
===> That the different period cooling/warming trends exist in narrow to wider bands over the total instrumental temperature record
===> That the 10-year trends (cyan) have a narrower ban than the 5-year trends (purple); the 5-year trends have a narrower band than the 3-year trends (green); the 3-year trends have a narrower band than the 2-year trends (blue); and finally, the 2-year trends have a narrower band than the 12-month (one year, red) band
===> The 1-year trends (moving 12-month) reach the greatest extremes, with excesses coming close to either a cooling trend of minus 80 degrees per century or a plus 80 degrees warming trend per century - amazingly, within a few years of each other
===> The greatest warming (acceleration) trends ever recorded took place during the 1870s; the largest cooling trends occurred during the late 1870s and early 1880s.
===> The highest 10-year warming trend (briefly at 4.14°C/century) happened in 1983, well in advance of the highest CO2 atmospheric levels achieved during the 1990s and the 2000s
===> The 2013 year-end per century trends (note the color arrows on chart's right axis) are well below previous warming trends
===> Although the 1-year moving trends in the distant past have approached both extremely high and cold temperature rates, the natural climate reactions then produced reversing course corrections (i.e. nature responds to extremes by avoiding long-term "runaway" and "tipping point" conditions)
===> The future climate will continiue to exhibit high natural acceleration and deceleration for both cooling and warming, guaranteed
===> The continuous growth of cumulative CO2 emissions over the entire span since 1850 has likely zero correlation with the constant acceleration/deceleration of natural climate temperature trends - CO2's impact on the trends is demonstrably minimal
===> The immense increase of CO2 levels (110ppm) since 1850 has not produced any trend peak, nor trough, during the post-WWII era that could be even remotely construed as "unprecedented" or "runaway" or a "tipping point" condition (with the possible exception being the 1-year cooling trend trough reached during the 1970s)
===> Simply put (which is blatantly obvious from the empirical evidence), human CO2 emissions or total CO2 atmospheric levels are not the "control knob"/"thermostat" that the white-coat, agenda-driven scientists say they can manipulate to manage the globe's temperatures.
Prior to the immense post-WWII consumer/industrial CO2 emissions, the world was warming, which peaked in the year 1944 (see chart).
The total pre-modern temperature increase to an identified peak (Sept. 1944) was +0.55°C, using the 12-month mean for year 1850 as the starting point.
Since the end of 1944 though, the modern era warming only added another +0.40°C on top of the 1944 peak, based on the high point for the rolling 12-month average, which was reached in mid-1998 (Aug. 1998).
With all the doom and gloom of global warming alarmism, this unexpected truth of modern global warming being less than the pre-modern era is an indicator that man-made catastrophe is not just around the corner. And this good news comes to us from the IPCC's own gold-standard for temperature observations - the UK's HadCRUT4 global dataset.
Also, the above chart of the 12-month means clearly shows a climate that moves from cooling to warming phases, and then back - a natural oscillation that 'catastrophic global warming' skeptics have long discussed, while being dismissed by the IPCC and its cohorts.
Keeping the observed oscillation in mind, the last significant warming ended with a peak in 1998 (the peak during 2010 was a very close second) and temperatures have since paused. Recently, this natural climate oscillation has been identified (by none other than the premier science journal Nature) as a potential cause of the 'Pause' that is generating such befuddlement for the "consensus" climate experts.
Not only has there been a very noticeable pause, since late 2001 there has been an actual cooling of global temperatures, which is noted on the chart with a light blue text box. As for the 12-month 2013 mean, it represents a slight temperature drop of -0.09°C since the 1998 peak (another case of those-stubborn-facts).
Understand, this chart does not explain the amount of any given warming/cooling that is due to either nature or humans, respectively. Nor does it tell us how long the 'Pause' will last or which direction temperatures will take after the stall. Some experts say temperatures will surely fall, while others claim that warming is hiding in the ocean deeps just waiting to climb out - your choice as to which view is correct.
The chart does suggest however that unpredictable temperature movements and climate change will happen regardless of CO2 levels and any human actions.
Finally, many CAGW alarmists predict that global temperatures will jump some 6 degrees by year 2100AD with a doubling of CO2. This chart's axes have been set to provide that context. Per the empirical history since 1850 and the recent global cooling, the 2100AD temp is much more likely to reflect the established +0.47°C per century trend...one thinks.
For those sharp-eyed readers, the chart title has slightly different temperature increase numbers than this article's text. The chart increases are based on the year-end that the peak temperatures took place; the increases used in the text are based on the actual month/year the 12-month mean peak happened.
Note: Excel was used to calculate the 12-month rolling means and plot the data. Used the HadCRUT4 dataset; the post-1958 CO2 dataset; and the pre-1958 CO2 dataset (divided annual ppm levels by 12). Don't know how to chart in Excel? It's easy. Go here to learn how.
Other IPCC consensus "experts" are wildly throwing around a hodgepodge of reasons that at last count was up to eight. Take your pick.
One reason definitely not on the table for discussion by climate reality deniers resisters is the obvious one: increasing CO2 levels are having little impact on global temperatures, which means that nature's normal climate forces overwhelm any CO2 influence. For the consensus scientists to open this can-of-worms would be the death knell of the AGW hypothesis - scientists driven by greed and the limelight do not willingly eviscerate the golden ox that has produced multi-billions for research grants and scientific studies.
Yet, when scientists examine the empirical temperature measurement datasets, it becomes readily apparent that changes in CO2 levels are not generating the expected changes in global temperatures, as predicted by the immensely powerful and sophisticated (and incredibly costly) climate models.
This obvious climate reality is portrayed in the above chart. Literally, 3-year changes in CO2 levels have no correlation with 3-year changes in global temperatures for the IPCC's modern era, starting with 1950. Simply put, one does not have to be a rocket scientist, nor a climate scientist, to ascertain that the CO2-centric AGW hypothesis is severely dysfunctional.
Eventually, global warming phase will return, as it always has in the past, but the climate models' prediction outcomes (and credibility) will likely be even worse, if that is even possible.
Poll after poll clearly indicates that Americans do not believe the Obama administration's anti-science claims (bogus?) regarding climate change and global warming.
Most Americans understand the day-to-day climate reality, thus they handily reject the climate hysteria and gutter-smears that both Obama and John Kerry feel compelled to utter.
As this accompanying chart reveals, global temperature change has decelerated and is now in negative (ie, global cooling) territory - the pink dot denotes current climate reality during the Obama administration.
This empirical evidence from the UK's climate research agency is the gold-standard, utilized by the UN's IPCC.
The red curve is a plot of 5-year "acceleration" (or lack thereof) presented as 5-year per century trend data-points (based on 60-month linear trends calculated for each month since 1850). The black plot represents a simple 10-year moving average of the 60-month data-points.
Why 5 years? Reality: The Obama administration has occupied the White House for the last 5 years.
What does the chart establish? Reality: Since a peak of warming "acceleration" during the second Bush administration, the short-term global warming trend has collapsed during Obama's term. Indeed, short-term global cooling is the current scientific fact.
How does the current short-term trend compare to previous administrations? Reality: During the modern era since 1950, Democrat administrations under Carter and Clinton reached the greatest warming accelerations (respectively, a 7.8°C/century trend during 1980 and a 8.4°C/century during 1998).
For comparisons sake, those 5-year acceleration peaks exceeding 5.0°C/century have been labeled on the chart with their respective White House occupants. And note, the greatest global warming short-term accelerations took place prior to 1950, plus being prior to the large influx of post-WWII consumer/industrial CO2 emissions.
When should a future president and the public become concerned about global warming caused climate change? Reality: When warming finally exceeds the unprecedented per century trend rate (11.5°C) previously reached during the Rutherford Hayes administration (1877-1881), for an extended period (say, 2 years as a minimum).
Again, the pink dot on the chart tells the climate science reality: Per the empirical evidence, the recent White House anti-science climate change comments are blatantly false, without any scientific merit, and are deserving of multiple Pinocchio badges.
More climate science reality: Those modern global and regional temperature charts that don't lie.
