The answers: Nope; Nope; Nope; Nope; and Nope...and the questions: "Does CO2 regulate global temperatures?"; "Does CO2 perform as global warming control knob?"; "Does CO2 act like the world's thermostat?"; "Does CO2 cause rapid and dangerous global warming?"; and, "Does CO2 produce accelerating global temps?" - the recent satellite empirical evidence provides the answers, much to the chagrin of the climate-doomsday cult proponents.....

This chart plots the global warming trends versus CO2 growth trends over a wide variety of time periods (last 30 years through the last 10 years, as of 10/31/2014).
As one can easily discern, while CO2 growth is exploding up, global temperature trends are collapsing over the same time.
In essence, the warming temperature trends have decelerated into cooling trends.
Visually, it is clear that modern CO2 growth has affected temperatures contrary to the predictions of the IPCC and AGW alarmists. In fact, the correlation between the CO2 and temp trends is negative.
Simply put, the trace gas CO2 does not regulate temperature; it does not act like a control knob or thermostat; and the greater growth in CO2 levels has not caused accelerated, dangerous warming.
Those are the stubborn facts. And it does not matter how many IPCC climate "experts" claim that CO2 is a 'control knob' or how many computer virtual simulations predict future dangerous temperatures based on CO2 being a 'regulator.' The climate reality of satellite empirical evidence falsifies those wildly speculative claims.
And it's not just the satellite empirical evidence that reveals the ongoing CO2/temperature disconnect.

Well...er...be happy, unless the long-term global temperature deceleration continues into a miserable and dangerous global cooling situation...as the GISS (NASA) empirical evidence indicates, CO2-caused "catastrophic" global warming is an absolute non-issue..... (click on below chart to enlarge)
What happens when one plots the GISS global temperature and CO2 trends for the long-term periods ending September 30, 1999 and September 30, 2014?
Yes, one gets the above two charts, revealing interesting, empirical climate science truths, such as:
1. The chart on the left (for periods ending Sept. 1999) reveals an acceleration of global warming trends, while the CO2 growth trends (see black dotted curve) across periods were fairly stable.
2. The chart on the right (for periods ending Sept. 2014) reveals a deceleration of global temperature change that over the 'last 10 years' reached a very slight global cooling status; yet, as can be seen, the CO2 growth trend was accelerating, reaching a rate robustly greater than those periods ending in 1999.
3. Other than a single datapoint (blue column), all the long-term temperature trends for the left chart exhibit warming greater than 1.5 degrees per century; in contrast, the majority of trends (blue columns) for the right chart are below 1.5 degree per century, despite faster CO2 growth and the associated higher atmospheric CO2 levels.
4. Rapid, dangerous, scary, undeniable, indisputable, irreversible, accelerating and catastrophic global warming claims made by various politicians, scientists, bureaucrats, celebrities and "journalists" are unequivocal lies. Long-term global temperature trends below 2 degrees (and going lower) are clearly the opposite of those widely-used, deceptive descriptors.
5. If it was not obvious before, CO2 is not a global "control knob" nor some type of "planet thermostat" - CO2 does not have much, if any, influence on temperature trends.
6. Confirming what climate skeptics (often called "deniers" for denigration purposes) have been stating for the last several decades, the climate changes constantly, primarily from natural forces. As a result, global temperature trends change frequently, exhibiting both cooling and warming modes across time spans.
We call it 'natural' climate change and ancient and historical climate records are replete with it. It happens often and, my goodness, it can be really extreme.
Now some caveats. The charts display a wide variety of temperature trends - they are not predictions for the future. They represent a snapshot in time and can change quickly.
One cannot conclude from the right chart that global temperatures will continue to decelerate into a glacial freezer. That would be exactly the same mistake that the climate "experts" made with the chart on the left - concluding that the temperature trends would just keep accelerating until hellish warmth would end-civilization-as-we-know-it.
And, these two charts cannot be used to claim that humans have no influence on global temperatures. Besides emissions of greenhouse gases, humans are constantly changing their environment which does have an impact (e.g. turning a corn field into an asphalt parking lot or massive deforestation in the world's major tropical rainforests or laying down a carpet of black soot on ice sheets).
Putting aside any further caveats, as an added bonus, the charts can be used to identify climate-liars. These are personalities and organizations that would never publish temperature charts as seen here. Instead, they resort to visual or verbal representations that today, or this month, or this year was the 'warmest' ever. This is not only the worst kind of cherry-picking, it is also incredibly lame.
Since the Little Ice Age (LIA), the world has been warming. It will continue to do so. Thus, we are going to keep experiencing warm(er) and warm(est) events - it's a no-brainer due to natural warming rebound. It will only stop happening when the world enters another mini ice age or worse. Those are the stubborn facts, which essentially makes CO2's trivial influence irrelevant.
When one hears the 'warmest' or 'warmer' refrains, that is when it becomes apparent one is in the company of a climate deception-meister.
Finally, let's all hope the global temperature deceleration shown on the right-most chart stops before it gets really ugly.

The well documented 'pause' for the global warming trend over the last 15+ years has generated over 50 hypothetical science explanations...the latest cloud coverage analysis appears to be a better explanation.....

Greenhouse gases, including CO2, looking less and less the major drivers of global temperatures and climate change.
When objective (non-IPCC) science research is done, without the political agenda, Earth's climate seems dominated by natural forces.
From 1950 to 1987 a strong relationship existed between the El Nino Southern Oscillation (ENSO) and HadCRUT4 global average temperature anomaly, interrupted occasionally by volcanic eruptions. After 1987 the relationship diverged, with temperature anomaly increasing more than expected, but was re-established after 1997 at an offset of ~0.48°C higher. The period of increased warming from 1987 to 1997 loosely coincided with the divergence of the global average temperature anomalies over land, which are derived from observation station recordings, and the global average anomalies in sea surface temperatures. Land-based temperatures averaged 0.04°C below sea temperatures for the period 1950 to 1987 but after 1997 averaged 0.41°C above sea temperatures. The increase in the global average temperature anomaly and the divergence of land and sea surface temperatures also coincided with two significant changes in global average cloud cover. Total cloud cover decreased during the period from 1987 to 1997 and, for most of the remainder of the period from 1984 to 2009, decreases in low-level cloud were accompanied by increases in middle and upper level cloud. These changes can be found in both global average cloud cover and in each of the six 30°C-latitude bands. The impact of these changes in cloud cover can account for the variations in HadCRUT4 global average temperature anomalies and the divergence between land and sea temperatures.
The EU elites and bureaucrats continue to beclown themselves...they are now going to pursue CO2 emission reductions that will accomplish zilch for the climate....
(click on image to enlarge)
The EU members have just agreed to reducing, by 2030AD, their own CO2 emissions by 40% based on 1990 levels (4.5 billion CO2 tonnes in 1990), for the next 17 years (including 2014, until the end of 2030).
That would simply average out to a 106 million tonne reduction per year. The result by end of 2030 would be 1.8 billion less tonnes emitted by EU countries, per year - assuming they can force every single EU country to comply (stop it! no laughing).
For context, the EU since 1990 has reduced their annual CO2 emissions by 598 million tonnes, total. That is an average of 26 million tonnes per year of reduction success since the end of 1990 - a fraction of the 106 million tonne per year reduction average needed for the next 17 years.
What would be the impact on global temperatures if the EU could wave a wand and immediately reduce their current emissions by 1.8 billion tonnes/year?
Absolutely NOTHING....their reduction plans essentially have an unmeasurable yearly impact of global temperatures (i.e. 'unmeasurable' not being at least a 2 decimal point degree (C) decrease/increase, for example, -0.01, -0.02, +0.01, +0.01 and etc.).
The basic arithmetic of CO2's past impact on global temperatures can be determined utilizing the standard 3rd party estimates of total global temperature increase and total CO2 emissions from 1850 on.
Using the historical CO2 emission and temp records, since 1850 global temperatures have increased by 0.00000000000061°C per CO2 tonne emitted (assuming the climate-doomsday alarmists' claims that all warming is due to CO2 and that all human emissions remain in the atmosphere from hundreds to thousands of years).
As can be seen with the above depiction of the 'C3' CO2/temperature estimator, the total reduction of 1.8 billions tonnes of CO2 emissions will have absolutely no yearly measurable impact on global temperatures (top panel of depiction).
(The various arithmetic calculations are not difficult, however they are tedious. So instead, one can use this simple 'C3' estimation tool to broadly estimate the impact of CO2 reductions/avoidance (or additions) on global temps.)
Since an immediate 1.8 billion tonne annual reduction is not possible, but a 106 million tonne reduction/year over the next 37 years (including 2014 through the end of 2050) could possibly be accomplished, what is the temperature impact with that scenario?
Again, absolutely no measurable impact on global temperatures (bottom panel of depiction). That's zero impact after 37 years of avoiding 106 million emission tonnes/year.
And by now you are probably asking yourself just how many years the EU has to reduce their CO2 emissions by 106 million tonnes per year for a measurable impact to be produced (i.e. -0.01 degree change)?
Approximately 165 years from end of 2013! But wait...there's more absurdity...if they're reducing CO2 emissions by 106 million tonnes per year, the EU finally gets to zero CO2 emissions by year 2056 (43 years from end of 2013 - currently, the EU emissions per year are about 3.9 billion tonnes per year).
Well, it means the EU won't ever reach the 165 year mark in CO2 reductions to achieve a -0.01 degree impact. And two, over the next 43 years, despite the 106 million tonnes/year reduction, the EU will still emit another 74.5 billion tonnes in total. That translates into a global temperature impact of +0.04.
On top of this obvious futility from the EU's newest CO2 moral posturing, the other countries of the world will just keep emitting CO2, completely wiping out any reduction the EU achieves. Simply put, no one gives a flying f*#k what the EU does any longer - not Russia, not China, not India, not Brazil nor any other nation on the cusp of climbing out of economic poverty.
Even if other major emitters were to go along with the EU's preening, they will simply ignore their CO2 promises to protect their economies and their citizens. And what will the EU do do enforce their moral superiority? Hmmm...think Russia's wars with the Ukraine and Georgia or think Iran and nuclear weapons - yep, you're right, in diplomatic-speak, the EU can't and won't do squat.
The EU's latest CO2 self-righteousness is as worthless as used toilet paper and everyone knows it.
Update: Another way to view the proposed 2030 impact of the new EU's CO2 reduction scheme.
If the EU's existing CO2 reduction achievements since 1990 continued through 2030, total EU emissions would be 63.1 giga-tonnes.That would produce a global temp increase of +0.039.
If the proposed 40% CO2 emission reduction by 2030 can be achieved, total emissions from 2014 through 2030 would 50.3 giga-tonnes. And that would produce a +0.031 increase.
It would seem the EU's plans to spend directly/indirectly billions-to-trillions of Euros to reduce global temps, by maybe only 8-thousandths of a degree, is tantamount to collective insanity by the elites.
Note: Global temperature source; historical and modern CO2 emission tonnes used by the 'C3' estimator tool. This tool is a quick and dirty means to calculate CO2's impact on temperatures. More information here.
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.....
(click on chart to enlarge)
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.
Science "journalists" who promulgate climate change hysteria have been recently pushing the fearmongering of the "hottest" year meme (or "warmest" if you prefer), which is essentially a lie...apparently, both the world's food crops and the public are simply now ignoring the proclamations of these chicken little, climate-cult doomsday criers.....
(click on image to enlarge)
The science is undeniable: the majority of plant life, including major agricultural crops, prosper under climatic conditions that are warmer and enriched with CO2.
Despite the recent significant pause in the global warming trend, world temperatures still creep up, always presenting opportunities for fearmongering-style reporting.
Yet the global warming doomsday prognostications of these "reporters" never materialize - even the International Red Cross report is not so blind to the climate "disaster" reality.
And as this adjacent U.S. Department of Agriculture (USDA) chart clearly documents, the world's major food crops produce greater bounty as the climate warms.
On the chart, superimposed is the latest NASA/GISS two-year average temperature on the chart, which indicates the slow creep of global warming. As greenhouse growers have known for over 100 years, a plant's productivity increases with a warmer climate environment.
It would seem that corn, wheat, rice and soybeans are no different than other plants.
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.
We've been told by the climate experts that increases in atmospheric CO2 levels will cause Earth to warm rapidly and dangerously, to the point where civilization's existence was threatened...but what if these "experts" were completely wrong and there is actual empirical evidence to prove them wrong?....
(click on chart to enlarge)
Well, the NOAA empirical evidence from their global temperature dataset indicates that longer term changes in atmospheric CO2 levels are definitely not producing anywhere near the expected long-term changes in global temps, as predicted.
Indeed, "wrong" is likely an understatement.
As a result, the experts' CO2-induced CAGW IPCC hypothesis is revealed for its true nature - basically, a hypothetical nothing-burger.
Let's be clear: the actual NOAA empirical evidence, from the global temperature climate instrumental records, does not support the hypothesis that long-term changes in atmospheric CO2 levels produce rapid accelerating, dangerous global temperature changes.
The adjacent graph of 10-year CO2 change plots, and concurrent 10-year change in NOAA global temperatures, is unequivocal: there is no correlation between the two, unless one wants to argue that a r2 of 0.08 somehow indicates a strong relationship.
The chart includes a 60-month average (purple) curve of the 10-year temp changes; likewise there is a similar average curve (dark grey) for the 10-year CO2 changes. Obviously, these curves show no relationship and essentially are now moving in opposing directions. The purple curve (temps) reflects a pattern of climate ups and downs, while the grey curve (CO2) since 1960 suggests an exponential growth situation.
In addition, it has been noted on the chart when extreme 10-year temperature changes have taken place - those rare increasing/decreasing temp changes that equal or exceed +0.6/-0.6°C. There have been 8 such events, 6 of which took place prior to 1960 (see light-yellow boxes on chart).
Hmm...what's that you say?...growing human CO2 emissions have caused a greater frequency of extreme climate incidents during the modern era? Ahem...a definitive 'Nope!' will suffice at this point.
In summary, if long-term changes in atmospheric (ppm) CO2 levels caused long-term changes in global temperatures, then the chart would have plots of the two principal change datasets tracking each other - in reality though, they're demonstrably different.
The NOAA empirical evidence strongly undercuts the CAGW hypothesis and, btw, demonstrates for the related hypothesis (which states that CO2 acts as a climate thermostat/control knob) is laughable nonsense.
Does all of the above indicate that human emissions have zero influence of global temperature changes? In fact, it does not indicate that; instead, it indicates that the CAGW hypothesis is without factual merit and that the climate sensitivity to CO2 is likely significantly lower than the IPCC "experts" proposed.
With all that said, the data strongly suggest, at best, a rather trivial CO2-influence on longer-term temperature change and its being indisputably non-dangerous.
Note: Temperature dataset; CO2 datasets. Excel was used to calculate 10-yr changes (ie. differences); to calculate r2 using the slope 'correl' function; and to produce plots and 60-mth average curves. To calculate a 10-yr. temp. change example: subtract the August 2004 temp. anomaly from the August 2104 anomaly. The same subtraction method is used to calculate 10-yr. CO2 level (ppm) changes. Starting with January 1890, the 10-yr chg. calculations can be made for each subsequent month, resulting in 1,496 'decadal' datapoints (NOAA monthly dataset commences at January 1880). 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.
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.....
(click on to enlarge)
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..."

Another spectacular climate model & "expert" prediction failure...the abysmal predictions generated out of billion-dollar climate models are well documented...predictions for water levels of the Great Lakes are no better....
(click on chart to enlarge)
The vicious combination of climate "experts" driven by a political-alarmist agenda and the indisputably incompetent climate models has long misled the taxpaying public and policymakers.
As the NOAA chart of the Great Lakes on the left clearly indicates, water levels are above the long-term averages. The predicted "tipping point" water level reduction from global warming and climate change is AWOL.
The frequent and spectacular prediction failures of the computer simulations and experts has been widely noted in the past.
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.
As the world's populace nutrition improves, according tothe experts at Food and Agriculture Organization (FAO) of the United Nations, the IPCC with its built-in political agenda to demonize CO2 and global warming, reports the opposite...lying is no longer even an art form for the fear-mongers of global warming and climate change catastrophe fantasies...it's blatant and brazen.....
(click on to enlarge)
The experts now estimate that the number of undernourished has decreased some 17%, from 1990 to 2103 - approximately 165 million less. Yet for the IPCC's 2014 AR5 report, they report an increase of 75 million.
There is no scientific reason, nor objective rationale for the IPCC misleading policymakers and the public so egregiously.
"Rather than using up-to-date FAO data showing a steady decline in undernourishment during a period of increasing temperatures (which they either were aware of or ought to have been aware of), the IPCC chose to feature an increase in an obsolete data set that had been previously highlighted in an “policy-relevant monograph” cited by IPCC. IPCC coyly described this earlier dataset as “provisional”...Why didn’t IPCC clearly report the long-term decline in undernourishment during a period of temperature increase. This is information that is relevant to policy-makers. And, in particular, why did IPCC highlight a supposed increase in “provisional” data (more precisely now long obsolete data) when the increase changed to a decrease in the up-to-date version of the data?...It’s hard to think of a good reason."
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.
Hey, not that anyone is keeping close track of when Obama will depart from the White House, and gee whiz, not that anyone keeps track of the global warming and climate exaggerations emanating from his administration...this stuff just seems to happen, ya' know...why should anyone care when the empirical and scientific evidence is totally ignored by elected Democrat officials?...go figure!, racist, denier, fellow citizen, comrade....
(click on chart to enlarge)
The current occupant of the Oval Office has now been there 66 full months. The adjacent temperature trends depict the first full 65 months of his administration, through June 2014 (July 2014 anomalies not yet available).
Simply stated, since Obama's tenure began, both U.S. and global temperatures have experienced a cooling trend - not the dangerous, rapid global warming from CO2 that he and other Democrats brazenly predicted, and still speak of like the crazy old uncle in the attic.
In addition, this administration continues to be robustly confused about modern extreme weather events and how they compare to what took place earlier in the 20th century.
Okay, it's 2,024 days checked off and only 899 days to go. Wouldn't it be great if President Obama just decided to go out in style with the truth that Americans now abundantly know (and desire from their leaders) versus pushing indefensible lies that aren't supported by any empirical evidence? Oh well...we can wish for utopia, no?
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.....
(click on graph to enlarge)
"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.....

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.

An analysis of NOAA's U.S. temperature dataset confirms the existence of fake climate warming that overstates actual warming by considerable amount...documentation and surprising revelations support the growing concerns by critics that U.S. climate scientists are driven by a non-science agenda.....
(click on image to enlarge)
Government bureaucrats and scientists have not exactly gone out of their way to publicize the growing use of estimated temperatures, instead of reality - actual temperature measurements.
For good reason.
Based on an examination by independent analysts, after 1990 the U.S. climate agencies chose to start replacing real-world measurements with entirely fabricated (i.e. "estimated") numbers.
Per the top chart on the left, utilization of estimated temperatures is now approaching 40%.
So, what's the problem with using NOAA's fake temperatures instead of real-world temperature measurements?
The bottom graph on the left explains the problem. The estimated temperatures produce a much greater warming trend then the actual temperature measurements.
By using estimates, government officials are able to claim bogus climate warming statistics in order to advance the scary talking points of catastrophic global warming and extreme climate change.
Deception is as simple as that, yet can be effective propaganda.
'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.

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.

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.

The UN's IPCC claim that large modern consumer/industrial CO2 emissions are causing maximum temperatures to increase across the globe proves to be without any empirical and scientific merit.....NOAA's NCDC division documents U.S. maximum temperatures are exhibiting a declining trend, not catastrophic "global warming"...
The adjacent chart is a fairly simple plot of the 20 hottest U.S. months, with the corresponding atmospheric CO2 level (black dots) for the respective month.
As the latest NOAA empirical dataset clearly indicates:
===> The hottest U.S. months took place during the 1930s, a very low CO2 period
===> The huge growth of atmospheric CO2 levels after 1949 did not produce the predicted increase of catastrophic, ever higher temperatures
===> The average maximum record temperature prior to 1950 (the 10 highest months of 1895-1949) was higher than the average maximum record temperature post 1950 (the 10 highest months of 1950-2014)
===> Despite the massive human CO2 emissions, maximum temperatures reveal a cooling trend of highs since 1950
This NOAA factual evidence for the continental U.S. confirms what has previously reported for maximum temperatures across the globe.

Has modern human CO2 emissions caused unprecedented, irreversible and accelerating global warming? Convincingly not, per an analysis of UK's gold-standard climate research dataset...certainly, a very inconvenient climate 'FactCheck'.....
(click on image to enlarge)
Regarding claims of "irreversible" and "accelerating" global warming, the scientific empirical evidence (analysis of monthly measurements) comparisons is indisputable: over the last 15+ years, global warming has gone AWOL, which the climate "experts" are mystified about.
Ergo, modern global warming has been in a non-accelerating state, a status reversal taking place since the late 1990's.
Here and here, the scientific evidence from NOAA, when analyzed from a 5-year climate change viewpoint, clearly shows that both modern U.S. and world-wide warming are not "unprecedented" when compared to earlier 20th century periods.
Moving on to a different perspective, the adjacent chart documents that modern atmospheric CO2 levels growth was approximately 6 times greater than during that of the pre-1950 period.
Yet, this immense growth of modern emissions barely produced an uptick in 10-year global warming averages, when compared to a similar time span for the pre-1950s. This is the undeniable result of an analysis of the UK's HadCRUT4 global climate record dataset.
The difference between the two period's 10-year average increase was a trivial +0.1°C - that's well within the range of what natural climate variation could explain. If HadCRUT3 datapoints were used instead, the difference shrinks to +0.05°C.
These differences are meaningless; of no material, meaningful climate consequence; and, totally undeserving of the label "unprecedented."
Climate Change FactCheck Summation: Analyzing 1,853 datapoints of moving 10-year average global temperatures establishes there is no significant empirical evidence from the gold-standard HadCRUT4 climate records that would even suggest that modern-era warming deserves the "unprecedented" designation. Simply stated, scientists and politicians utilizing that adjective are intentionally being deceptive in order to solely advance a political agenda. Likewise, the deceptive use of the descriptors "accelerating" and "irreversible" are also not supported by any scientific evidence.
Additional information regarding the chart:
From a 10-year average global temperature low, established during November 1976, the modern warming period spanned 410 months, ending during December 2010 when the 10-year average peak occurred.
The pre-1950 (prior to the huge 'modern' consumer/industrial CO2 emissions) 10-year average temperature peaked during May 1945. Creating a similar 410-month span, establishes April 1912 as pre-1950 low point for this apple-to-apple comparison.
The atmospheric CO2 level (ppm) growth amounts depicted by the chart are based on these two 410-month periods.

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.”

The political agenda of "global warming" is so important to government-sponsored scientists that massive fabrication of temperature warming is required to convince policymakers and the media.
The latest analysis (see graph) reveals the extent to which this temperature fabrication goes.
Although the actual climate records' empirical evidence shows essentially a flat temperature trend for the U.S. since 1985, NOAA has added warming "adjustments" to the historical empirical database to create a false warming trend of 1.5°F per century.
As this analysis indicates, consensus corruption of empirical science by U.S. scientists is active and robust, done with a seemingly obvious intent to deceive.
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.

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?

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.
If wild-assed guesses and purposeful doomsday, fear-mongering claims are the "new science" gold standard, then Obama's 'National Climate Assessment' report must be a winner, no?.....well, it's at least deserving of 5-Pinoccio gold stars for anti-science propaganda...

The 2014 climate-doomsday assessment report recently issued by the White House and Democrat cronies has not been well received by actual climate scientists.
The report is a compilation of every scary climate prophecy imaginable, most of which are highly speculative with little, if any, likelihood of happening.
Ahem.....yes, Virginia, you are more likely of being struck by lightening exactly between the eyeballs than suffering through any of the Democrats' climate doomsday scenarios.
Besides the White House's extreme scare-mongering, the report's credibility is also D.O.A. due to its blatant falsehood regarding "CO2-caused" warming of the globe and the U.S.
===> "The government’s newest national assessment of climate change declares that increased global warming is affecting every part of the United States."
From a vast array of empirical reports (here and here), recent research and widely disseminated media reports, it has been well verified that the "expert" predicted accelerating freight train of dangerous global warming has been stopped cold in its tracks.
Obama's assessment: it completely ignores this major climate reality that so dramatically differs from the previous global warming alarmism speculations.
And the actual scientific truth about global temperature change is not difficult to determine, since all it takes to analyze temperatures is to download the NOAA/NASA satellite temperature datasets and then plot the measurements using Microsoft Excel.
That is what has been done in producing the accompanying charts.
The top graph plots the changes in tropical oceans (a latitude range of -20 to +20); the tropical atmosphere (a latitude range of -20 to +20); and the continental U.S.
Obviously, since 1996, the last 18 years has witnessed its normal wide variation in temperature swings but the overall linear trends are cooling for all three datasets, NOT WARMING as predicted.
The bottom chart represents the moving 5-year averages of all three of the same datasets, plus the moving 5-year average of atmospheric CO2 levels (ppm). Clearly, the huge growth in CO2 levels has had zero global warming impact on the 5-year temperature change over the last 18 years, contrary to the Democrats' "consensus" predictions.
This actual empirical evidence devastates the White House claim that Earth is becoming Venus-like, where CO2 causes the tropical atmosphere to develop incredible hotspots, which then produces a boiling-off of sea water, starting with the tropical oceans. As can be seen here, this is the entire "scientific" basis of the Democrats' extreme climate change, doomsday predictions.
Doomsday predictions that do not comport with any known climate reality on Earth (again, view above graphs).
Unfortunately, reality has not kept this White House from misleading Americans on a wide range of issues, including Obamacare; the Benghazi terrorism attack; the IRS politicization; the NSA's illegal spying on Americans; the Operation 'Fast & Furious' fiasco; and etc.
Thus, Obama's climate assessment report utilizes the same lie-at-all-costs tactics as the previous instances. This report is just another attempt to bamboozle the public.
"5 reasons voters don’t believe the White House about global warming: OVERREACH, HYPOCRISY, AGENDA-DRIVEN, UNILATERAL, NOT CREDIBLE" - that's how the Washington Post assesses Obama's assessment.
And of course, when this latest fear-report fails to convince the public, the liberals' anti-science approach will then embrace other tried and true "professional" tactics - like this.
Note: Yes, you too can do your own empirical analysis - download datasets used in Excel to produce above charts, linear trends and moving averages. Btw, U.S. April anomaly used was an estimate (included in the download). Hey, don't know how to chart in Excel? It's easy. Go here to learn how.
The adjacent image represents a temperature reconstruction from the Greenland ice sheet boreholes. The image was included in a peer reviewed paper that was published in 1998, which is approximately the same time the infamous 'hockey stick' graph was produced.
Although this paper confirmed the findings of a massive amount of previous research that the Medieval Warming generated higher temperatures than the current warming, the IPCC instead conferred star status to the statistically-tortured 'hockey stick' graph, which showed the previous warming to be less than the current era, and then was subsequently found to be without credible merit - a statistical travesty.
Why did the IPCC go with the unproven, statistical abomination that quickly smeared (irreparably?) the reputation of climate science?
"Christy’s assessment, when combined with the UEA emails, provides substantial insight into how this hockey stick travesty occurred. My main unanswered question is: How did Michael Mann become a Lead Author on the TAR? He received his Ph.D. in 1998, and presumably he was nominated or selected before the ink was dry on his Ph.D. It is my suspicion that the U.S. did not nominate Mann (why would they nominate someone for this chapter without a Ph.D.?)...Instead, I suspect that the IPCC Bureau selected Mann; it seems that someone (John Houghton?) was enamored of the hockey stick and wanted to see it featured prominently in the TAR."

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.....

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...

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.

Like the UN, the IPCC is a political organization that seemingly has a primary objective of misleading the public and policymakers about climate science. Another example of such behavior is.....

The empirical evidence and peer reviewed research is indisputable - essential food production has dramatically improved while CO2 levels and global temperatures increased.
Those are the stubborn facts that the adjacent chart reveals as unequivocal.
Yet, because of the political-driven agenda the IPCC pursues, their latest report states that the world's food production would be more "secure" if CO2 emissions were reduced. Hmm...the exact opposite of known scientific fact.
"There, it can be seen that enriching the air with CO2 almost always leads to significant increases in the photosynthetic rates and biomass production of all of the world's major food crops. And as for the highly-unlikely increase in global temperature that the world's climate alarmists predict to result from projected increases in the air's CO2 content, there are also many studies that reveal the positive consequences of warming for agriculture in Earth's cooler high-latitude regions, such as the recent study of Meng et al. (2014) dealing with maize production in the northern reaches of China. And there is also the significant body of work that reveals that as the atmosphere's CO2 concentration rises, the various temperatures at which different plants photosynthesize most proficiently rise right along with it..."
"Yet the primary efforts of both of these entities [Ed. the UN's IPCC and the UNFCCC] have been, and continue to be, directed against that which is most needed to produce the required amount food, as they both argue for reductions in anthropogenic CO2 emissions, which comprise much of the aerial "food" that sustains all of our food crops."
Truth be told, the headline of this post is not an IPCC quote but obviously it represents what the IPCC is attempting to convince the public of, and unfortunately, the real-world, objective science does not support it in the least.
Summary: The IPCC's fundamental lies continue to establish the blatant anti-science which permeates the entire UN's climate "research" reporting - it's propaganda spin all the way down.
