NOAA's latest U.S. temperature dataset reveals that over last 20 years (including 1996), May temperatures have been on a cooling trend: a -0.8°F/century trend.
In addition, the same dataset for 12-month periods ending May shows a cooling trend over 19 years. That trend is a -0.4°F/century.
Regardless if one refers to these climate temperature dynamics as a 'pause,' a 'stall,' a 'hiatus,' or a 'plateau,' it was not expected - no alarmist hypothesis or theory-based scenario predicted this outcome.
Note: Temperature trends are for the continental U.S. The official climate agency source of trends and chart.
Today's climate-doomsday cult celebrities and global warming alarmists continue to deny the truth about past extreme weather and natural disasters that took place well before atmospheric CO2 surpassed 350ppm...now combine that with current stable of IPCC-favored scientists who deny that the previous generation of scientists were predicting global cooling...and what do you get?...a fringe group representing a tiny slice of the world populace...a slice of fanaticism in total denial of the existence and power of natural climate change...past, present and in the future...they're *Deniers 'R' Us*, no?.....
IPCC Scientists' Favorite "Climate Science" Movies
There are past periods of extreme weather and severe natural disasters that just stand out as examples of strange climate activity and weird 'earthly' behavior.
The decade of the 1970s is one such period of bizarre, freaky and dangerous weather that prompted serious scientific discussions regarding global climate change at the time.
And the most discussed condition of climate change that had the focus of scientists and government experts?
Below is a list of early 1970's weather (and other natural disaster) events and links to multiple articles about the most popular climate change hypothesis at the time.
And these adjacent movie posters?
Pure Hollywood, utilizing anti-science propaganda masquerading as possible climate catastrophic conditions from global warming.
And try guessing the audience that embraces the gutter of such doomsday garbage - of course, you aren't surprised are you?
Winter can be sooo cruel...especially for scientists who have long immersed themselves in the pile of manure that CO2 CAGW hysteria represents...good news, though!...NASA and James Hansen have a fallback position...namely, the previous climate hysteria predictions they and the press were pushing on Congress and the public.....

This updated NOAA U.S. temperature map is a stark reminder of the incredibly cold climate that northern and eastern areas of the US have recently experienced. The bitter cold, in particular, impacted those regions east of the Mississippi River, with states butting up against Canada taking the brunt.
It's also a reminder of those predictions by NASA experts and computer models, as promulgated during 1988 congressional testimony, that accelerated global warming would significantly impact the U.S., with many "experts" then claiming our future was one of warmer winters and no snow.
More to that point is the adjacent chart of US Nov/Dec/Jan temperatures (28 years) and trends since that 1988 testimony. It represents the following 8 states: Wisconsin, Michigan, Ohio, Pennsylvania, New York, Vermont, New Hampshire and Maine (all these states are east of the Mississippi and share a border with Canada).
To summarize the chart essentials:
1. Winter temperatures (Nov/Dec/Jan) exhibit a strong variability (the blue columns). Clearly, increasing atmospheric CO2 levels during this period has not caused ever-warmer winters.
2. Many of the winters are below the 1988 average of 27.58°F, including the winters of 2014 and 2015. (see blue dashed line)
3. Despite the very warm winter of 2002, the overall warming trend (orange curves) of winter temperatures has collapsed to a cooling trend of -5.7°F. There is no escaping the obvious NOAA empirical evidence that greenhouse gases are not producing the predicted accelerated warming.
4. The 10-year average winter temperature (the green curve) peaked in 2007 from a low experienced in 1989. Without any doubt, those few very exceptional warm winters (5 of the 28 winter datapoints) have definitely moved the average up. With that said, since 2007 it has declined slightly.
Is the U.S. just a rare anomaly where a cooling winter trend, not warming, is happening? Unfortunately, for the public and CAGW-scientists, regions with cooling trends are becoming more common.
Additional current empirical evidence that CO2 does not cause dangerous "warming" winters:
Note: Source of dataset for 8-state winter temperature chart produced by Excel. Using Excel calculated the 8-state winter months average; the 10-year trends and averages that begin with year 1988 on the chart used U.S. winter (Nov/Jan/Dec) temperature data starting with November 1979.The 1988 blue-diamond column on chart represents year of James Hansen global warming testimony.
Powerful and wealthy elites, global warming alarmists and climate-doomsday cult'sters' often make statements like..."it is indisputable, global warming is unequivocal"...but here's the problem...that is an exceptionally misleading, anti-science piece of propaganda that should never be tolerated...even NOAA's empirical evidence shows the lie of that type of statement.....

In previous articles, evidence was presented that much of the globe has not warmed since year 2000 - areas such as regions of the world's ocean, the lower atmosphere and major regions of the U.S.
However, if global warming is "unequivocal" from CO2 emissions and other greenhouse gases as claimed, then how is it possible that major components and areas of the world are not warming?
As it turns out, where one actually measures temperature change is a huge factor whether the end result is "global" warming or not.
Simply put, as all climate scientists agree, urban/metro and airport areas are robustly warmer than surrounding areas, during both the daylight and night hours. And, as it turns out, they are warming at multiple times greater rate than rural regions.
They are not warmer because of more CO2 and methane. They are warmer because they have more people, cars, schools, stores, restaurants, planes, trucks, buses, trains, factories, concrete, asphalt, buildings, parking lots and etc.
And because of some very incredibly shortsighted decisions, the majority of climate stations are now located in the urban/airport areas, with most of the rural stations being eliminated. Thus, there now exists a built in bias impacting global warming calculations, which heat-up the actual climate reality.
How big is that bias impact? That's what the adjacent graph helps to reveal.
Take Reagan National Airport in the Washington DC metro. It's warming at an astounding +14.6F degrees per century pace over the last 15 years. Now compare that to a rural area about 170 miles west of DC, in the very northwest part of Maryland. (This portion of the country is called the Allegheny Plateau region a NOAA/NCDC designated climate division). It's cooling at a -3.1°F per century rate.
An 18 degree warming rate difference within a 3-hour journey? CO2 is not responsible for that.
So, why do the U.S. politicos, elites and media believe the world is "unequivocally" warming?
Because they live and work in highly urbanized areas that have the necessary attributes that cause a positive temperature feedback - often referred to as the Urban Heat Island effect (UHI). They are oblivious to the fact most of the world's populace does not live in these concrete-cocoon heat traps and are not experiencing ludicrous warming where the wealthy and powerful congregate.
Again, examine the above chart. Urban/airport warming locations (Reagan Natl, Dulles, Richmond and Baltimore) exhibit fast "global" warming growth. The two highly populated states (Virginia & Maryland) surrounding these urban regions show more moderate warming. And nearby rural areas (the Appalachia Mountain and Allegheny Plateau areas of Maryland) actually have cooled over the last 15 years.
Importantly, the rural areas' temperature cooling are more in line with the entire continental US climate, as shown.
Why does the U.S. exhibit an overall cooling trend for the last 15 years? Obviously, geographically, the U.S. has a much greater abundance of rural areas, similar to the Allegheny Plateau region, than urban/airport complexes. In fact, it is claimed over 90% of the U.S. is considered rural.
Memo to Republicans: For discussions and debates about climate change, use only official weather/climate station thermometer datasets located in rural regions and/or from satellites. Urban/airport thermometers do not measure temperature change from CO2/GHG climate change - they measure temperature change produced by the concrete-cocoon urbanization. Demand that NOAA/NASA/EPA primarily report satellite/rural temperature changes as a leading indicator for potential greenhouse gas influences. Dismiss with contempt those global warming calculations that are quoted which include the hot airport/urban thermometers.
Note: Source for urban and regional 15-year annual temperature datasets. Above Excel chart only shows per century linear trends calculated by Excel, not the annual datapoints. For the chart, adjusted y-axis to better fit all trends on a single viewable image for the article.
Do you recall when climate "experts" told us it's was all about physics...that increasing CO2 atmospheric CO2 levels would absolutely produce perilous, breakneck accelerating climate temps...they said it was all "consensus" science and, btw, it's the physics, stupid...ooops, those pesky and stubborn facts strike again.....

Clearly, over the last 30 years when CO2 emissions and other greenhouse gases were skyrocketing, temperature trends here in the U.S. were significantly decelerating.
The deceleration of temperature warming is also seen in the major satellite measurements and the global land and sea observations, although not as pronounced as what took place in the continental U.S.
When the correlation is calculated for the chart's temperature trends and the average CO2 levels for each time period, the result is a -0.93 with a r2 of +0.86. That puts it in the universe of almost a perfect inverse (negative) correlation - higher CO2 levels seemingly drives temperatures to deceleration and cooling.
We say 'seemingly.' First, it pays to remember that trends are not predictions and don't go on forever - they change. Second, today's negative correlation could go positive in the not too distant future. And of course, third, whether it's positive or negative correlation it does not prove cause.
With those caveats stated, it is absolutely true that the consensus "physics" is not supported by the actual empirical climate evidence over more recent years. Also, the "clear and present danger" of global warming for the U.S. is a generous mix of hysteria, myth and fiction. Science factual truth is not in this mainstream mix it would appear.
Note: Using Excel and the U.S. temperature dataset from this source, one can calculate the monthly temperature anomalies from the absolute temperatures (used the 1901-2000 baseline for each month); Excel's slope function will then provide the trends for each time period; and then Excel can plot the resulting trend columns. This is the annual CO2 dataset used to calculate each period's average CO2 level. Don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
Remember when those NASA/NOAA climate experts predicted a rapidly dangerous warming for Americans?...based on the last 15 years, coastal urban elites just might consider moving to fly-over-country where cooling rules...their dedication to the absurd beloved precautionary principle certainly seems to dictate this simple precaution.....
As this NOAA/NCDC regional climate map reveals, the vast majority of the continental U.S. has not warmed for the last 15 calendar years.
Specifically, for the entire continental U.S, the 2000-2014 calendar span has seen a -2.7°F/century cooling while 7 of the 9 climate regions had cooling or temperature trend stability.
However, there are two regions of the U.S. that have experienced warming trends - on the east and west coasts.
It is highly doubtful that global CO2 emissions would only affect these two geographic areas and not "global warm" the rest of the country. Objectively, it's more likely that there are other micro-regional climatic and human factors involved for the specific coastal state warmings.
Since 1997, the continental U.S. suffers from a significant cooling trend, per NOAA...will CO2 emissions be able to save us from the looming next ice age?.....
(click on image to enlarge)
As NOAA is now reporting, the U.S. is in the midst of an extended cooling trend - 18 years and counting.
According to the IPCC and 97% of all "expert" climate scientists, the explosive growth of CO2 emissions and other trace greenhouse gases should have caused accelerated warming, not cooling.
The cooling trend is at a -1.9°F per century for the last 18 years. And since the end of the 20th century, the cooling has accelerated to a -3.5°F trend/century (years 1999 thru 2014) . That would be a doubling-down on 'Ooops', so to speak.
2014 the "hottest" U.S. year ever meme? Nope, didn't happen. In fact, this past year turned out to be the 5th coolest during that 18-year period.
Here is an interesting task for any CO2-centric global warming/climate change alarmist:
Identify from the 1980-1990's a single NOAA/NCDC/NASA climate expert on the taxpayer dole, at that time, who publicly stated this was a likely result. And the billion-dollar+ government-funded climate model(s) that actually predicted this very inconvenient climate cooling outcome.
In front of cameras, a hot and sweaty James Hansen of NASA gave his famous global warmingEOTWAWKItestimony...lucky for the rest of us, this climate "expert" was spectacularly wrong.....
(click on graph to enlarge)
During a hot June 1988, NASA's James Hansen provided a provocative, stage-crafted testimony to the U.S. Senate.
His message? The world of 1988 was the hottest ever, since the 1800's, and it was due to humans' fossil fuel CO2 emissions; and more importantly, global warming would continue its upward path, rapidly getting worse and then becoming a threat to civilization unless CO2 emissions were constrained - i.e. reduced significantly.
Why his EOTWAWKI message? Because the modern crystal ball - his computer climate model simulations - told him so.
This chart plots the global temperatures using the most advanced, costly climate measuring technology provided to the scientific community by the American taxpayer. The empirical measurement evidence over the last 26.5 years since his testimony tells a different story than what Hansen predicted.
What do the satellites say? This state-of-the-art measurement technology ignores crystal ball predictions by experts and instead objectively reports that over the last 18 years "global warming" has been a non-issue. Despite record amounts of greenhouse gases being spewed into the atmosphere, global warming has not accelerated and has not become a threat.
How bad were Hansen's computer model predictions?
In his testimony, he spoke of causation between global warming and CO2 emissions - the more CO2 released, the greater and faster temps will rise. Yet, over the last 18 years, the world has experienced a very tiny cooling trend, per the satellites. And the "causation"? Well...ahem...calculating the statistical correlation between global temperatures and CO2 ppm levels over the last 18 years produces a negative correlation, with a r2 of 0.0004.
Dr. Hansen does deserve credit however. The first 8.5 years after his testimony, satellites measured the global warming trend at a +1.22°C increase by 2100AD. And the r2 for temperatures and CO2 was 0.21 (note to climatologists of alarmism persuasion: one does not want to make predictions of catastrophe with this statistical attribute level).
The conclusion? The end of the global warming 'EOTWAWKI' as we know it, no? Damn those stubborn facts!
In the previous 'C3' article, we looked at U.S. temperatures since 1988 when a NASA climate expert in U.S. senate testimony made predictions of near-future catastrophic climate change and, of course, dangerous global warming.
As the article documented, temperatures in the U.S. have essentially been at a standstill over the last 10+ years, and catastrophic climate change (with its millions of IPCC predicted "climate refugees") is nowhere to be found.
The end result is the undeniable evidence that America's climate records are non-consistent with the well publicized climate expert climate predictions, and also with the billion dollar super-computer models that experts and mainstream journalists claim to be climate-omniscient.
It begs the question: Is the non-consistent climate reality in the U.S. also found in other parts of the world?
Turns out that the UK climate records, as represented by the Central England Temperature (CET) dataset, reveals the same expert abject failures and non-consistency with model simulations. "Rapid" and "dangerous" accelerated warming hasn't taken place there either.
Unlike the continental U.S., with its abundance of micro and regional climates, the small island area of Great Britain affords less climate variety yet produces similar warming/cooling trends over the recent past.
Like the U.S. dataset plots, the CET dataset is for the full 26 years (312 months through Nov. 2014) since late 1988 when both UK and U.S. catastrophic climate proponents initiated their public fearmongering campaign - the year of James Hansen's scare-testimony.
The adjacent UK chart depicts both the plots for 60-month temperature and CO2 averages. Clearly, the predicted rise in temperature due to higher CO2 levels has not happened - this is not consistent with any climate model simulation that the experts tout.
With a r2 of 0.00 between monthly CO2 and temperatures values, the UK climate records also confirm the legitimate dismissal of the argument that CO2 acts as a "control knob" - some type of global temperature thermostat that UN elite bureaucrats and national politicians thought they could just dial for a desired climate.
And that "warming" trend for the last 13 years that just scares-the-poopie out of UK's elites? A -4.8°C per century...yep, a significant cooling trend.
In summary, the combined CET and U.S. climate records add to the empirical evidence disproving the hyperbole for CO2-caused disastrous global warming and catastrophic climate change. In reality the hyperbole is without any scientific validation.
Damn those stubborn facts.

The mainstream media's current du jour "climate science" claim is that 2014 is headed towards being the world's "warmest" year, ever.
Unfortunately, for the media that pushes the hysterical, that claim is actually without statistical merit, since the uncertainty error bars are large. In statistical terms, there's a darn good chance it's not the warmest year.
Then there is the jumbo elephant in the press room that "journalists" flat-out don't acknowledge, let alone report: the state-of-the-art climate satellite technology completely undercuts the world's "warmest year" hype.
And then there is the whole issue of where exactly is all this "dangerous," "out-of-control" warming taking place. For example, is it happening here in the U.S.?
Based on the multitude of anti-science, exaggerated "warmest-year-ever" paragraphs being produced by American reporters, one would think the good citizens of the U.S. are in the midst of the civilization-ending climate-fry.
But, as usual, the empirical evidence reveals the absolute distortions the media fabricates, per the latest U.S. climate records from NOAA.
Case in point: the adjacent graph is a plot for the last 26 years (312 months) of U.S. temperatures through November 2014 - since 1988. The red curve is a 60-month average that clearly indicates "global warming" in the U.S. has gone AWOL for at least a decade - on 'hiatus,' so to speak.
Then there is the 60-month plot of CO2 emissions (black dots), which obviously tells a different story then the press fabrication that the "rapid" global warming we are "suffering" from is a direct result of human CO2 emissions.
Hmmm...clearly temperatures do not react to CO2 as those crack science reporters "report."
This NOAA empirical evidence is unequivocal and indisputable, yet the mainstream media refuses to inform the American public of these most basic climate record facts.
So why did we pick 1988 as a starting point for this analysis?
Back in the summer of 1988, NASA had its climate expert, James Hansen, testify before the U.S. Senate. In his testimony, he predicted that across the world temperatures would rise dangerously due to human's increasing CO2 emissions.
As a result of the accelerating temperatures, Hansen foretold of major climate catastrophes that would plague the U.S. and the world within 20 some years, if business-as-usual CO2 emissions were not curtailed.
It's now 26 years later, and as the above graph depicts, global warming has stalled; CO2 emissions have not been curtailed in the least. And for the U.S. (look closely at the graph), continental temperatures actually experienced a cooling trend stretching over a decade.
The dramatic climate change disasters that NASA and Hansen predicted? Not even close to happening.
And those are the stubborn facts - much to the chagrin of the UN bureaucrats, national government elites and mainstream hacks journalists.

Note: US temperature dataset can be downloaded from here. NOAA/NCDC reports absolute temperatures and these can be converted to anomalies using the 1901-2000 baseline averages that NOAA provides.
As decades of climate-doomsday cult 'AGW' propaganda have made abundantly clear, the world is supposedly endangered from rising human CO2 emissions...that produces a corresponding rapid and accelerarting global warming...which then results in CAGW hell for civilization...unfortunately for the IPCC (and alarmists), their own empirical evidence refutes the hypothesis and eviscerates the entire concept that CO2 is some sort of "control knob" thermostat for Mother Earth....
(click on chart to enlarge)
Simply stated, the climate reality facts do not bode well for those who still promulgate that Earth's environment is in 'crash & burn' mode from human CO2 emissions.
Whether it is the unanimous opinion by scientists regarding the 18-year "global warming" pause; or the last 9 years for the complete lack of major hurricanes; or the inexplicable and surprisingly thick Antarctic sea ice; or the boring global sea level rise that is a tiny fraction of coastal-swamping magnitude; or food crops exploding with record production; or multiple other climate signals - it is now blatantly obvious the current edition of the AGW hypothesis is highly suspect.
Not only is the AGW hypothesis invalidated by close to twenty years of empirical evidence, the CO2 as a "control knob" concept has been shed of any practical merit.
This has been discussed multiple times at 'C3' over recent years. Now, stepping back a few decades, during a 1988 Congressional staged testimony - conspiracy to mislead comes to mind - the top NASA climate expert predicted that 'business as usual' CO2 emissions would cause rapid and accelerated global warming.
Eventually, building on that 1988 performance, other climate experts developed a hypothesis that CO2 acted as the proverbial control-knob thermostat for the global temperature.
But in reality, is that even remotely accurate?
The above reality chart of empirical evidence affirms what the IPCC truly does not want to discuss: the "control-knob" concept is literally a myth.
The chart plots two-year temperature changes since 1988, with the respective two-year CO2 changes (ppm). It has been 26 years since that testimony-performance, thus there are 13 two-periods plotted on the chart. In addition, the linear trend for the HadCRUT4 gold-standard temperature dataset and NOAA's CO2 dataset are shown moving in opposite directions.
There is no doubt. The increasing CO2 changes are not producing the requisite increasing temperature changes, as predicted. Visually, the correlation between the two appears very lame, at best. The actual r2 is a meager 0.12 - yes, that's two plus decades of statistical nothingness.
Conclusion: Those stubborn climate facts are not kind to the ever-fading, CO2-induced global warming hypothesis. Climate change is always happening but it is highly unlikely that the miniscule trace-gas CO2 is a major driver (sure, a minor player, but not one that controls the world's fate). Time for policymakers to abandon the control-knob myth and instead focus on adaption preparation for all types of climate change.
Additional global and regional temperature charts exhibiting the lack of CO2 influence.
Note: The chart plots and linear trends were created using Excel, and the HadCRUT4 dataset and NOAA CO2 dataset. The plots cover discrete two-year periods, starting with October 1988. The CO2 change is scaled to one-tenth of actual (so that temp changes are visually apparent). Hey, don't know how to chart the above in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
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.
Note: Temperature dataset and CO2 dataset used to produce Excel charts and 2nd order fitted trend of the trends. Excel's slope function was used to caluclate each period's trend, then multipled by 1200 to produce a per century trend. Hey, don't know how to chart in Excel?

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.
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.

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.....

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..."

A combination of fanatical green activists and wealthy crony-capitalists has produced a strong influence over the Obama administration and its climate policies/regulations ...Democrats in Congress have also been bought off...unfortunately for the American public, these corrupting motivations lead the government and bureaucrats down policy paths that ignore climate history and its science.....

"What's the weather tomorrow?" 'Been, there, done that'
"What will the climate be 10 years from now?" 'Been there, done that.'
Regardless of human activities and human CO2 emissions, the climate and weather have a strong, built-in natural rhythm that takes place, relentlessly.
The scientific evidence is unequivocal about this: the global climate repeats itself.
The adjacent chart plots the scientific empirical evidence - the globe naturally cycles through periods of extreme cooling and warming. And as the evidence reveals, the Obama/Kerry climate-porn duo exist during a period of cooling, not the extreme accelerating global warming that they claim.
For context, the chart extends back to the 1850s, with major peaks in the global warming trend identified with the president occupying the Oval Office at the time.
Note that the highest peaks (ie. dangerous and rapid global warming) took place prior to 1950 and the modern era's industrial/consumer CO2 emissions. Note also that after peaks were reached, the climate naturally repeated its cooling phase - every single freaking time.
And because presidents and Democrats during those times did not deny the natural cyclical peaks and valleys of the global climate, they did not end up making fools of themselves by claiming that CO2 'vapors' had given the world a fever from a runaway, tipping point warming.
By understanding the nature of the 'been there, done that' climate, past politicians did not hysterically succumb to the likes of today's anti-science charlatans advocating the deindustrialization of America, and the hypocritical snake-oil cronies wanting to steal from the American taxpayers' wallet.
Put another way, past politicians accepted those stubborn facts of empirical science, no matter how inconvenient.
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.
Note1: My bad. Found dumb error on original chart. Now corrected. No corrections to above text required.
Note2: NOAA U.S. temperature dataset and Excel used to produce above chart. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
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.

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

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

Prior to the immense post-WWII consumer/industrial CO2 emissions, the world was warming, which peaked in the year 1944 (see chart).
The total pre-modern temperature increase to an identified peak (Sept. 1944) was +0.55°C, using the 12-month mean for year 1850 as the starting point.
Since the end of 1944 though, the modern era warming only added another +0.40°C on top of the 1944 peak, based on the high point for the rolling 12-month average, which was reached in mid-1998 (Aug. 1998).
With all the doom and gloom of global warming alarmism, this unexpected truth of modern global warming being less than the pre-modern era is an indicator that man-made catastrophe is not just around the corner. And this good news comes to us from the IPCC's own gold-standard for temperature observations - the UK's HadCRUT4 global dataset.
Also, the above chart of the 12-month means clearly shows a climate that moves from cooling to warming phases, and then back - a natural oscillation that 'catastrophic global warming' skeptics have long discussed, while being dismissed by the IPCC and its cohorts.
Keeping the observed oscillation in mind, the last significant warming ended with a peak in 1998 (the peak during 2010 was a very close second) and temperatures have since paused. Recently, this natural climate oscillation has been identified (by none other than the premier science journal Nature) as a potential cause of the 'Pause' that is generating such befuddlement for the "consensus" climate experts.
Not only has there been a very noticeable pause, since late 2001 there has been an actual cooling of global temperatures, which is noted on the chart with a light blue text box. As for the 12-month 2013 mean, it represents a slight temperature drop of -0.09°C since the 1998 peak (another case of those-stubborn-facts).
Understand, this chart does not explain the amount of any given warming/cooling that is due to either nature or humans, respectively. Nor does it tell us how long the 'Pause' will last or which direction temperatures will take after the stall. Some experts say temperatures will surely fall, while others claim that warming is hiding in the ocean deeps just waiting to climb out - your choice as to which view is correct.
The chart does suggest however that unpredictable temperature movements and climate change will happen regardless of CO2 levels and any human actions.
Finally, many CAGW alarmists predict that global temperatures will jump some 6 degrees by year 2100AD with a doubling of CO2. This chart's axes have been set to provide that context. Per the empirical history since 1850 and the recent global cooling, the 2100AD temp is much more likely to reflect the established +0.47°C per century trend...one thinks.
For those sharp-eyed readers, the chart title has slightly different temperature increase numbers than this article's text. The chart increases are based on the year-end that the peak temperatures took place; the increases used in the text are based on the actual month/year the 12-month mean peak happened.
Note: Excel was used to calculate the 12-month rolling means and plot the data. Used the HadCRUT4 dataset; the post-1958 CO2 dataset; and the pre-1958 CO2 dataset (divided annual ppm levels by 12). Don't know how to chart in Excel? It's easy. Go here to learn how.
Poll after poll clearly indicates that Americans do not believe the Obama administration's anti-science claims (bogus?) regarding climate change and global warming.
Most Americans understand the day-to-day climate reality, thus they handily reject the climate hysteria and gutter-smears that both Obama and John Kerry feel compelled to utter.
As this accompanying chart reveals, global temperature change has decelerated and is now in negative (ie, global cooling) territory - the pink dot denotes current climate reality during the Obama administration.
This empirical evidence from the UK's climate research agency is the gold-standard, utilized by the UN's IPCC.
The red curve is a plot of 5-year "acceleration" (or lack thereof) presented as 5-year per century trend data-points (based on 60-month linear trends calculated for each month since 1850). The black plot represents a simple 10-year moving average of the 60-month data-points.
Why 5 years? Reality: The Obama administration has occupied the White House for the last 5 years.
What does the chart establish? Reality: Since a peak of warming "acceleration" during the second Bush administration, the short-term global warming trend has collapsed during Obama's term. Indeed, short-term global cooling is the current scientific fact.
How does the current short-term trend compare to previous administrations? Reality: During the modern era since 1950, Democrat administrations under Carter and Clinton reached the greatest warming accelerations (respectively, a 7.8°C/century trend during 1980 and a 8.4°C/century during 1998).
For comparisons sake, those 5-year acceleration peaks exceeding 5.0°C/century have been labeled on the chart with their respective White House occupants. And note, the greatest global warming short-term accelerations took place prior to 1950, plus being prior to the large influx of post-WWII consumer/industrial CO2 emissions.
When should a future president and the public become concerned about global warming caused climate change? Reality: When warming finally exceeds the unprecedented per century trend rate (11.5°C) previously reached during the Rutherford Hayes administration (1877-1881), for an extended period (say, 2 years as a minimum).
Again, the pink dot on the chart tells the climate science reality: Per the empirical evidence, the recent White House anti-science climate change comments are blatantly false, without any scientific merit, and are deserving of multiple Pinocchio badges.
More climate science reality: Those modern global and regional temperature charts that don't lie.

And now NOAA has just released their U.S. dataset update, which reveals that U.S. winters (November, December, January), over the last 20 years, have cooled at a -2.5°F per century rate. The adjacent NOAA/NCDC web site chart depicts that cooling trend.
As this NOAA dataset suggests, the reason for worse winter weather in the U.S. is likely a cooling climate change that has followed the previous modern warming - a natural climate response.
Again, 'those-stubborn-facts' that are so inconvenient for politicians.
The empirical evidence is indisputable and unequivocal.
The continental U.S. has been cooling (-6.5°F/century rate) over the last 15 years, per NOAA. This can no longer be denied by the scientific community and the politicians fanatically pushing the anti-science claim that dangerous and rapid global warming is taking place, due to human CO2 emissions.
This chart plots the most recent monthly U.S. temperatures through January 2014, including the simple 36-month moving average of CO2 atmospheric levels over the last 180 months.
While "global warming" activists/proponents focus on superficial, short-term cherry-picks of the "hottest ________" (just fill in the blank with 'day', 'week', 'month', 'quarter', 'year', etc. to mimic a typical fanatic's cherry-picking spiel), those stubborn climate facts, which are critical, remain simple: the entire globe has experienced a long warming 'pause' and America's climate has been on a cooling trend over that same time span.
Scientists are unable to explain this 'standstill' using the "consensus" AGW hypothesis, and any discussions of the 'inconvenient' U.S. cooling trend are entirely avoided by politicians, climate agency scientists/bureaucrats and other warming advocates.
The observed current U.S. cooling trend is not a prediction, but it does indicate that the continental landmass is affected by powerful, non-CO2 greenhouse gas factors that may continue for the near future.
Note: Chart's linear trend is calculated using monthly absolute temperature values. If using anomalies instead, based on monthly averages from 1901 to 2000 base period, the per century cooling trend is -2.4°F.

The HadCRUT4 global temperature dataset for 2013 was just published. On review of the released annual temperature averages that the UK experts calculated, the calendar year 2013 global temp was cooler than the 1998 mark.
So, during that 15 years of massive human CO2 emissions, the fearsome "runaway" warming was not so much. In fact, after the spewing of some 450 gigatons of fossil fuel emissions the temperature needle hasn't budged, it's actually lower in 2013.
The UK's findings match what other climate experts have found and are now debating the cause. This 'Pause' (aka 'The Hiatus') in global warming has even been noted in Congressional testimony as a matter of official record.
"The biggest mystery in climate science today may have begun, unbeknownst to anybody at the time, with a subtle weakening of the tropical trade winds blowing across the Pacific Ocean in late 1997...Average global temperatures hit a record high in 1998 — and then the warming stalled....But the pause has persisted, sparking a minor crisis of confidence in the field. Although there have been jumps and dips, average atmospheric temperatures have risen little since 1998, in seeming defiance of projections of climate models and the ever-increasing emissions of greenhouse gases."

It was noted previously that the continental U.S. has been cooling over the last 16 years, at a rate of minus 3.8°F per century rate. This was not predicted by any U.S. climate scientist, nor by NOAA, nor by NASA and certainly not by the political technocrats at the UN's IPCC.
As the NOAA/NCDC climate record reveals, the breadbasket areas of American have been cooling for a longer period - 17 years. The above images reflect the empirical evidence for the primary U.S. corn growing areas., which is cooling at a minus 4.0°F/century rate.
The other major 3 crop regions all show similar type of cooling rates over the last 17 years ending 2013. (see: soybean temperatures, map; spring wheat temperatures, map; and winter wheat temperatures, map)
If this cooling trend were to continue, it would spell disaster for the world's hungry. Let's hope 'the pause' in global warming does not last much longer since it unfortunately seems to project a cooling regime over the U.S.
Central England Temperatures (click images to enlarge)
Recent mainstream press articles, plus those on the blogosphere, indicate a growing concern for a soon-to-come global cooling period, that some are even referring to as a potential mini-ice age. This sudden turn of events is entirely counter to all the "expert" consensus and IPCC predictions that claimed runaway global warming was civilization's greatest threat.
The impetus for the new publicized fears of cooling comes from the indisputable empirical evidence that global warming is suffering a non-predicted 'hiatus' (i.e. warming is stalled, paused, stopped, etc.) these last 15+ years. Combine that pause with the additional empirical evidence of solar activity being at a minimum and major ocean oscillations being in non-warming phases and that combo spells t-r-o-u-b-l-e.
One region of the world that may already be experiencing the impacts of a global cooling phase is The Midlands of central England.
The above charts are plots of the Central England (CE) Temperature record. The left chart plots the annual dataset (light green) back to inception, 1659AD. The maroon curve is a simple 25-year average of the annual temperatures. The chart also includes a plot of a 25-year average of annual CO2 atmospheric levels.
Obviously, the CE region has had a high degree of climate temperature variability over the records 355 years, coupled with an observed warming trend generated with the rebounding from the depths of the Little Ice Age (LIA).
Starting in the early 1700s, there are signs the warning rebound was beginning, but it wasn't until the late 1800's that one can discern a strong post-LIA warming trend that ushers in the modern era. This positive spike of temperatures was well before the huge CO2 consumer/industrial emissions of the late 20th century.
Actually, using the 25-year moving average curve, one can see 3 distinct periods of recovery from the LIA. By the end of 2013, the 25-year average appears to reach its peak - the "warmest" ever.
However, by zooming in on the last 25 years since 1988 a different story is told - a climate cooling story.
The chart on the right is a plot of CE temperatures since 1988 - yes, the same year that climate scientists warned us that we were at global warming's death door. The chart's red and grey curves are 3-year averages and a linear trend line has been added (dark green).
Clearly, as this plot of modern temperatures reveals, for 25 years the CE region has had a slight cooling trend. This trend would produce an overall cooling of +0.53°C by 2100AD, if it were to monotonously continue (it won't). Adding to the consensus "expert" woes, any observed relationship between temperatures and CO2 levels is non-existent, if not a negative correlation over the last 2.5 decades.
If huge emissions of CO2 are not driving temperature increases, then the apparent cooling must be a function of more powerful forces, such as described in this latest peer-reviewed study. With that said, all empirical evidence points to the fact that climate science remains unsettled and that the CO2-centric CAGW hypothesis is essentially without clothes.
Since the significant global impact of the 1997-98 Super El Nino, the overall U.S. has experienced a 16-year cooling trend of -3.8°F per century.
Lengthy cooling trends are also seen at the 14, 12, 10 and 8 year marks for the continental U.S.
(Side bar: NOAA calculates the 2-year per century cooling trend at a -293°F, yet they calculate a 6-year warming trend at +26.9°F. How's this? Well, both calculations are impacted immensely by the outlier hot year of 2012. These two calculated figures represent a cautionary tale to using trends less than 10 years, and that no trend ever represents a prediction.)
The above map (click on to enlarge) depicts temperature trends for each state within the continental U.S., since the Super El Niño years - the last 16 years.
As clearly shown, the vast majority of states (77%) have experienced a long-term cooling. The huge global emissions of CO2 has not produced any global warming across a great swath of America.
A suggestion: The GOP/Republican politicians in Washington wanting to address the Democrats' climate change hysteria may want to laser focus their attentions on those states that are the warming exceptions. For these 11 states, it would be of scientific benefit to understand how they managed to be such extreme "warming" exceptions - a detailed, objective, 3rd party forensic audit of the temperature dataset for each warming state would seem to be in order, at a minimum.
Source of temperature trends. Additional regional temperature charts/maps.
If human CO2 causes indisputable, relentless, unequivocal, unprecedented, accelerating and tipping point catastrophic global warming, then why is the U.S. cooling over the last 15 years?
Indeed, the "experts" have been unable to scientifically explain why there has been a 'hiatus' or 'pause' in global warning, let alone the cooling trends experienced in various parts of the world. That doesn't mean the scientists are not speculating as hard as possible as to why - so far, they have conjured up 7 reasons they never mentioned prior to the global warming going AWOL.
When a rational, believable and testable hypothesis finally does arrive maybe it will be able to explain the decadal temperature changes the U.S. has experienced since 1895.
The above chart plots the NOAA/NCDC U.S. dataset decade-end temperature changes, including the change over the 10-year period ending 2013. Stating the perfectly obvious, the infamous consensus experts' "unequivocal" warming is anything but. In spite of massive human CO2 emissions, a recent state of cooling changes dominate in the U.S. (see last two blue columns).
Another interesting point that the chart reveals is that the largest decadal temperature increase did not occur during the modern late 20th century, or 21st century for that matter. The biggest increase took place during the decade of the 1930s.
The chart also has a plot of new human CO2 emissions for each decade. For example, the decades ending 1999 and 2009 had new emission totals of 234 billion tons and 286 billion tons, respectively. (Note: The early decades were estimated using CO2 information from here; for years 1965 and later, CO2 emissions are from this source.)
Unfortunately for the climate science consensus experts, this latest release of NOAA temperature data confirms that they are essentially clueless when it comes to predicting regional and global temperature changes. Likewise, it also confirms that one of the scientists' favorite concepts - that human CO2 emissions are similar to a world "control knob" or thermostat for climate temperatures - is simply idiotic, not even plausible.
Finally, this additional empirical evidence firms up the growing belief that the CO2-centric AGW hypothesis is an anachronism, now deserving to be placed on the ash heap of failed pop-culture science. Maybe it will still fly on cable's Discovery Channel but in the realm of hard-truth scientific endeavors it's a failed religion.
This top plot of satellite global temperatures is scientifically unequivocal (click on to enlarge):
The actual empirical evidence from state-of-the-art measurement technology reveals a global warming spike during the late 1990's (due to the Super El Nino), but after that, essentially zilch.
Thus, for the last 20 years (240 months) the global warming trend of +0.52°C by 2100AD is 'climate insignificant' - a trend that climate scientists certainly don't get excited about.
And when one examines the last 17-years, the satellite global temperature trend becomes slightly less than zero (i.e. global cooling). As a prominent climate alarmist scientist determined recently in a peer reviewed paper:
“There is a lot of noise in the climate system and it is quite possible that the noise can mask the effects of man-made carbon dioxide for a period of time. However if the slope is zero for 17 years, then we cannot blame noise any more but we have to face the facts that we humans do not affect the climate to any great extent.”
The bottom plot of global temperatures confirms the atrocious climate predictions of the IPCC "expert" climate models. This is irrefutable evidence that the consensus climate models can't predict squat and should not be relied upon by policymakers.
Finally, it is well established that Obama and his administration are serial pathological liars (sounds harsh but it is undeniable). This is not only true in the health care and Obamacare policy arena, but is also a common denominator in their climate change alarmist claims.
The irrefutable, unequivocal, non-global warming trend continues.
As these graphs reveal, the latest NOAA temperature dataset, through August 31, 2013, confirms that the U.S. and its major crop regions are experiencing a cooling trend. (click on graphs to enlarge)
Note, this has taken place despite the largest 15-year production of human CO2 emissions, ever. Contrary to every single IPCC and U.S. climate model.
Update clarification: The above plots from the NOAA web site are based on moving 12-month periods ending in August (each 12-month period starts with a year's September temperature and ends with the following year's August temperature).
It has been noted by others that the MSNBC news outlet and the OFA (Occupy / Obamaites) crowd are not the sharpest knives in the drawer, so to speak.
Fighting climate change, supposedly due to global warming / cooling / warming, is an idiot's Don Quixote obsession, especially since climate change is constantly happening, naturally.
And as this actual result happened at the MSNBC/OFA event, it provides proof that the public is a lot smarter than the activists.....my god, Chris Matthews et al. are truly pathetic, no?
Honestly, it just makes you wonder if MSNBC personnel are stupendously stupid or pathological liars or just need to fanatically obsessively agree with Obama despite the current climate reality - cooling.
The latest IPCC climate "expert" hypothesis that global warming causes everything, including the recent global cooling, has been verified by NOAA's up-to-date temperature dataset - through March 2013, it would definitely appear that the previous 15-year global warming caused the subsequent 180-month global cooling while atmospheric CO2 levels still remained completely irrelevant
Note: Above chart uses the NCDC global dataset published through March 2013. The left two columns (CO2 & temperature) represent the 15 years (180 months) ending March 1998, the right two columns represent the 15 years ending March 2013.
While left-leaning U.S. politicians, bureaucrats and the partisan mainstream press continue to push the silly catastrophic AGW hysteria from human CO2 emissions, a significant cooling trend (per NOAA) across a critically important global breadbasket continues - if the latest 15-year global cooling trend persists, crop yields will suffer immensely
As has been well documented, global warming has gone AWOL and in some regions of the world, global cooling trends have materialized, which scientists across the world are starting to express concern with.
In the key crop regions of the U.S., there has been an extended cooling trend that persists despite the immense human CO2 emissions released over the last two decades. The above four NOAA charts depict those cooling trends across the a wide swath of American agricultural production. These charts represent the main American corn, soybean, spring and winter wheat growing areas.
What the huge U.S. breadbasket needs at this point is a few years of some good old fashioned global warming that will reverse the potential devastation a mass cooling would deliver to crop yields.
Unfortunately, though, it appears nature is not delivering what the American farmers and ranchers need this spring.
100% of climate scientists now agree that accelerating global warming has robustly stalled- the IPCC's gold-standard UK HadCRUT global temperature dataset confirms what skeptical scientists have long publicly discussed
There no longer is any serious debate of the non-existence of dangerous, accelerating global warming from human CO2 emissions - literally, from all current climate empirical evidence, it does not exist.
In the scientific real world though, there is an abundance of peer reviewed, solid scientific evidence pointing conclusively to a future of both moderate temperature and climate change.
As the above chart reveals, atmospheric CO2 levels have constantly increased since 1990 - see recent CO2 charts here.
In contrast, the IPCC's gold-standard global dataset (above chart) confirms temperatures have stalled since 1998 - actually, they have slightly cooled at a -0.08 degrees/century trend.
The chart's solid blue curve is a simple three year moving average of non-scary global temperature change that current political elites conveniently ignores and the MSM refuses to report.
Current global temperatures are significantly below NASA's climate model and "expert" predictions - note the dotted red line on chart.
All the major climate agency computer models, based on human CO2 emissions, have failed spectacularly.
Modern weather disasters (e.g., blizzards, tropical storms, etc.) portrayed by political elites and MSM "reporters" as caused by "climate change" are the exactly the same bad weather disasters that took place during earlier periods of low atmospheric CO2.
The United Nations IPCC climate agency has a gold-standard dataset used since 2007 to make global climate predictions - the HadCRUT3 gold-standard confirms that the predicted dangerous global warming is non-existent, and unequivocally, that CO2 is not the world's thermostat
Taxpayer-funded climate scientists and ideologue politicians have continuously predicted that the globe will suffer from dangerous global warming; and they claimed that human CO2 emissions acted as the world's climate thermostat.
As the adjacent chart reveals, the IPCC's own temperature gold-standard (HadCRUT3) refutes the "experts" and "elites" hysterical, anti-science prognostications:
#1. The global temperature dataset clearly indicates that the world has exhibited a slight global cooling trend since the spike in temps from the super El Niño of 1997/98. That's 180 months (15 years) of non-dangerous global warming.
#2. The chart's thin black line is a plot of the monthly changes in CO2 levels. The correlation between monthly temperature and CO2 changes ranges from slim to none - this supposed thermostat relation of CO2 to temperatures has a ludicrously low R2 of 0.01. CO2 is not only not a "thermostat," it's likely not even a major climate forcing, per the actual data.
#3. While global temperatures have been slightly cooling, the global changes in monthly CO2 levels have been slightly increasing (note smooth grey curve - a 2nd order fit).
#4. Simply stated, this actual IPCC gold-standard empirical evidence robustly refutes all the anti-science predictions/claims of climate "experts" and alarmist "elites."
And, as we are currently witnessing, the green-sharia, anti-human fanatics are now having to do some serious crawling-back from their previous anti-CO2 agenda and bogus-science blinders to the climate reality.
Taxpayers have spent billions on CO2-driven climate model "science," which the empirical evidence now suggests was like pouring money down a rat-hole....the abysmal prediction failure of CO2-centric models is simply fact - are there actual scientific models that can replace this current wasteland of biased AGW climate research?
As major mainstreamnewsoutlets are starting to report, global warming has essentially disappeared, replaced with a slight cooling trend in recent years. Taxpayer-funded climate scientists are finally being forced to go on record stating the obvious - their global warming predictions were incorrect.
Their favorite euphemism to describe what is happening is that global warming is at a "standstill." Even the most infamous climate reality denier has started using that terminology to describe a decade of non-existent warming - he can't quite yet bring himself to say global cooling.
Three of the above charts (top-left, top-right and bottom-left) represent the state-of-the-art models used by the "consensus" climate experts. As seen, all three have been spectacularly wrong through the end of 2012.
These three models (World Climate Research Programme, NASA-GISS and the IPCC) are CO2-centric climate models - global warming and climate change are primarily driven by levels of atmospheric CO2. As a result, they have long predicted dangerous and accelerating global warming for Earth's atmosphere, oceans and land surfaces - and it bears repeating, they have been spectacularly wrong.
The majority of scientists now agree that these "consensus" science models are flawed (at least 97% of scientists would agree ;-) and are incapable of accurately predicting global temperatures. Thus, newer models based on non-CO2 drivers of climate are starting to see the light of day, so-to-speak.
One such newer model is represented by the bottom-right chart above. This model appears to have better global temperature prediction capabilities, which also happens to verify that CO2 is not the principal climate driver, as scientists on the taxpayer dole claim (and misrepresent).
The UK's HadCRUT3 global temperature dataset has been the IPCC's gold-standard for its political-agenda "science" reports - unfortunately for the IPCC, the HadCRUT dataset also confirms the disappearance of global warming, replaced by a very slight cooling trend
It is estimated some 440 gigtons of human CO2 emissions have been produced over the last 15 years, in contrast to the estimated 330+ tons during the previous 15-year period ending 1997.
Further, it was estimated by the consensus "experts" that a large increase in human emissions over the last 15 years would bring the world hellish warming. It has not happened.
The climate scientists and their associated climate agencies were immensely wrong, as the adjacent chart indicates.
As can be seen, over the first 15-period, prior to 1998, there was a strong warming trend (+1.4 degrees per century). As a result, the experts said human CO2 was the cause. They then emphatically predicted that this warming trend would continue and even accelerate. But it didn't - instead it decelerated.
As the chart depicts, the last 15 years ending 2012 has seen a very slight decline in temperatures, wiping out the strong positive warming trend completely. This small cooling trend in surface temperatures is also supported by the satellite observations of the atmosphere. The global warming was wiped out even though total human CO2 emmisions were a third larger - 110 billion tons more than prior 15-year span.
This empirical evidence has become so convincing that the cooling deniers are even starting to eat that awful tasting, proverbial crow (here and here).
In the meantime, they debate amongst themselves about how befuddled they are concerning the lack of warming, obviously confirming what skeptics knew all the time - their bizarre anti-CO2 phobia and rigid consensus constraints have long blinded them to scientific truth.
Long-term climate change is represented by 30-year changes in a climate variable, one being temperature change...whether 30-year temperature change is due to humans (ie, human CO2) can be ascertained readily by examining the changes in the NASA's global temperature dataset
The adjacent chart is not one likely to be publicized by the green-sharia scientists at NASA's GISS; nor will "journalists" at the NY Times and Washington Post report on it. To do so would make them apostates to the anti-CO2 religion jihad.
Regardless, the empirical temperature observations that NASA documents clearly indicates that the monotonous increase in atmospheric CO2 levels have had little impact on long-term (30 years) temperature change.
As the chart depicts, 30-year temperature changes resemble a sine wave (oscillation) that has nothing to do with human CO2 - instead, that sine wave pattern is natural, and easily overwhelms any CO2 impact.
Since the "consensus" global warming has disappeared "unexpectedly," how long before the World Wildlife Fund (WWF) and other green-sharia outlets start claiming that recent global cooling is the result of human CO2 emissions?

As documented by previous temperature charts, the global atmospheric temperatures have been on a declining trend over the last 15 years. The adjacent chart depicts similar results with a change: instead of CO2 levels (ppm), this chart shows the recent human CO2 emissions in gigatons.
Since 1983 (30 years), there have been two distinct phases of global temperatures.
On the right side of this chart, the last 15 years had human CO2 emissions released into the atmosphere increasing by over 100 billion tons. However, instead of an acceleration of the predicted atmospheric warming, the prior 15-year trend was reversed - a new global cooling trend was established.
This is clear empirical evidence of the spectacularly wrong prediction by the environmental organizations' green-sharia "experts" and the IPCC's "scientists."
1. Human CO2 emissions are not a global temperature "thermostat"
2. The current AGW hypothesis is severely weak, at best
3. Any regional/local surface warming experienced is obviously not a result of the actual cooling global atmosphere...thus, must be due to other factors (hmmm....fabrication of warming temperatures anyone?)
4. Billions to trillions have been wasted by governments, industries and consumers to avert a predicted, slam-dunk warming from a failed greens' hypothesis
5. If this global atmospheric cooling trend persists much longer, the greens and the MSM "journalists" will pirouette 180 degrees and claim human CO2 causes cooling (and climate change)
The 2012 year-end satellite measurements continue to be cruel to the IPCC's green-sharia scientists - this UN agency has long predicted huge atmospheric global warming from CO2 emissions .....yet in reality, global cooling currently dominates
(click on images to enlarge)
The above chart is the plot (Figure 1) of satellite atmospheric temperature measurements provided by RSS, plus CO2 measurements from NOAA (data sources).
Clearly, as CO2 levels have monotonously increased over the last 17-years (why 17?), global temperatures have not increased with any significance. By year 2100, this "warming" trend would produce a projected increase of one-third of a single degree - rather insignificant and hardly noticeable.
The UN's IPCC's catastrophic global warming (CAGW) hypothesis, which the vast majority of empirical-based scientists now reject, demands that ever increasing atmospheric CO2 levels cause the atmosphere to rapidly warm. This accelerated, man-made atmosphere warming would then significantly warm the globe's oceans and land surfaces, quickly making Earth inhospitable from incredibly high temperatures and horrific climate change disasters.
Contrary to the United Nation's "science" though, global temperatures have morphed over the last 30 years from a warming trend to a cooling trend despite the huge increase in CO2 levels.
This next set of temperature plots (Figures 2, 3, 4 and 5) depict the global atmosphere temperatures and CO2 levels over four different time periods. These plots, plus the 17-year chart, formulate an empirical reality that refutes the UN's non-empirical CAGW hypothesis:
1. Atmospheric CO2 levels have increased relentlessly over the last 30 years
2. For all time periods, the average atmospheric CO2 levels have exceeded the supposedly "safe" 350 parts-per-million (ppm)
3. As figure #2 shows, there is a modest global warming trend evident over 30 years
4. Figure #2 also reveals that most of the global warming took place prior to 1999
5. Since 2003 1993, the 20-year plot (figure #3) has a smaller warming trend - less than 1.0 degree by year 2100
6. The 15-year and 10-year charts (figures #4 and 5) have no warming trend, proving that a very slight atmospheric global cooling has dominated since the late 20th century
7. 2012 global temperatures are well below previous highs over the last 30 years.
8. The 17-year plot (figure #1), which is favored by some CAGW scientists, confirms that global atmospheric warming has been robustly insignificant, contrary to their own predictions
Conclusions: Per the actual satellite empirical evidence, global atmospheric temperatures have been cooling over the last 15 years despite the IPCC "consensus" predictions that global warming would have to be produced if CO2 levels exceeded the 350 ppm level. Global cooling has now dominated for a significantly extended period, which demonstrably proves that CO2 is not a "global thermostat" as claimed by many of the UN's green-sharia scientists. (Note: linear trend representations are not predictions.)
Likewise, claims that global warming is "rapid," "accelerating," "irrefutable," "unprecedented," "incontrovertible," and/or "irreversible" are outright known falsehoods.
Finally, any journalist, scientist, politician or bureaucrat using such terminology to describe global temperatures is an unequivocal liar - that is the simple, empirical truth.
The HadCRUT global temperature dataset (Sept. 2012) was recently published - this is the dataset used in the most recent IPCC report and it currently shows that global warming from CO2 emissions is essentially non-existent
(click on image to enlarge)
Over the last 180 months (15 years) the atmospheric CO2 levels have continued to increase at a rapid pace, but the globe (land and ocean) has cooled during that same time.
For the 15-year period ending September 30, 2012, the world experienced a very slight cooling trend of -0.12°C per century.
In contrast, for the 15-year period ending September 1997, the globe was warming at a +1.18°C pace.
The IPCC predicted that global warming would result from increased atmospheric CO2 levels - however, since the beginning of the 1997 Super El Nino, global cooling has been the result
(click on image to enlarge)
The RSS satellite global temperature measurements indicate that the 1997-98 Super El Niño started from the low of April 1997. From that point, and all the way through July 2012, the global atmosphere has cooled - a total of 184 months. This cooling trend took place during a significant increase of atmospheric CO2 levels.
This slight cooling trend is opposite of what the IPCC (and NASA's James Hansen) predicted for global temperatures.
The IPCC prediction of rapid global warming is based on the hypothesis that human CO2 emissions would increase atmospheric CO2 greenhouse gas levels; the increase of greenhouse gases would allow more radiated heat to be retained; the retained heat would warm the atmosphere; and, the atmosphere would then warm the world's oceans and land surfaces. Such predicted warming would set in motion a "runaway tipping point" that would produce catastrophic climate disasters and a doomsday for civilization.
Instead, as the adjacent chart indicates, the lower atmosphere since 1997 (per the RSS satellite measurements) has actually been exhibiting a cooling trend, versus the the obvious warming trend for the January 1980 to April 1997 period (red curve on chart).
Like the RSS dataset, the HadCRUT global temperatures also exhibit almost the same warming/cooling dichotomy. What is very apparent in both datasets is that the '97-98 Super El Niño shifted temperatures up to a new level, which then global temperatures resumed their normal variation around. Subsequent to this temperature range shift, growing CO2 emissions have not caused the long predicted "global warming."
#1. Satellite measurements reveal both a modest global warming and very slight global cooling period since 1980.
#2. Levels of atmospheric CO2 appear to have no consistent influence on global temperatures since 1980.
#3. Global warming is not "irrefutable," "unequivocal," "rapidly increasing," "accelerating," "incontrovertible," "indisputable," "unquestionable" nor "unprecedented." It's quite the opposite of all these qualifiers.
#4. Any IPCC scientist, climate researcher, academic, government bureaucrat, journalist and pundit who states and/or implies that any 'qualifier' in point #3 is the 'truth,' is, quite honestly, a serious liar. The empirical evidence is the scientific truth, not a person's blatant verbal misrepresentation.
#5. Politicians and celebrities who state and/or imply that any 'qualifier' in point #3 is the 'truth' is at best, stuck-on-stupid. Unfortunately, that seems to be the dominating characteristic of individuals involved in the political, sports and entertainment worlds. (Although, with politicians it may not be the case of being stupid, instead it may be more of a case of being criminally corrupt in order to enrich himself via "green" projects - think Solyndra.)
#6. As the satellite data show, the hot summer in the U.S. was not a result of global warming (as suggested by many covered by points #5 and #6) since global atmospheric temperatures during May, June and July were not extreme nor unusual.
A high climate sensitivity to growing human CO2 emissions is absolutely essential to the catastrophic anthropogenic global warming (CAGW or AGW) hypothesis - the climate empirical evidence refutes the high sensitivity claim though
(click image to enlarge)
In climate science reality, the actual global temperature observations over the last 15 years do not support the catastrophic anthropogenic global warming (CAGW) hypothesis.
Central to the CAGW hypothesis is that increasing human CO2 emissions will raise atmospheric levels of this greenhouse gas. Subsequent to the atmospheric CO2 increase, global warming will automatically and consistently increase.
Once the globe starts warming, the AGW hypothesis states that a high climate sensitivity to CO2 will initiate a dangerous positive feedback loop: the rising temperatures will increase water evaporation; the powerful atmospheric greenhouse gas water vapor will then increase; then global temperatures will increase even more, the melting of ice sheets occurs; thus, less solar energy will be reflected into space; and global temperatures will then increase even more; and etc., etc.
This powerful and relentless positive feedback loop will produce unequivocal, robust, significant, unprecedented, irrefutable, rapid and accelerating global warming. At least that is what every "expert" climate model based on the CAGW hypothesis predicted.
But did the above prediction/scenario/forecast happen? Nope, not even close. In fact, the opposite happened.
The adjacent chart depicts the last 30 years of increasing CO2 levels and global temperature trends. This actual climate evidence is sliced into two time periods: the 15 years ending July 1997 and the 15 years ending July 2012. The real world evidence reveals the following:
1. The far right column (grey) shows that CO2 levels were increasing at a 147 ppm per century rate by the end of July 1997. Actual CO2 levels were at the 364 ppm mark.
2. For the 15 years ending 1997, global temperatures were increasing at +1.08°C per century trend (red column).
3. Since July 1997, the growth of CO2 levels has increased to a 197 ppm per century trend, and now stands at the 395 ppm mark.
4. After 30 years of increasing human CO2 emissions and faster growing atmospheric CO2 levels, the last 15 years have witnessed the previous global warming morph into a global cooling tend (blue column) at a -0.24°C per century trend.
Conclusions: The climate scientist and climate models that have long predicted catastrophic global warming from CO2 emissions are proven to be undeniably incorrect. The AGW hypothesis does not reflect climate reality. The actual empirical evidence proves the CAGW hypothesis to be irretrievably wrong. The climate sensitivity to CO2 levels is, at best, tiny. The natural forces of the climate will produce negative feedbacks that completely overwhelm the hypothetical CAGW positive feedback loop. Thus, while CO2 emissions will likely induce a slight warming, the natural climatic forces will dictate and dominate our climate future.
Finally, any "science" association, journalist, politician, celebrity, weatherperson, bureaucrat and pundit who says that dangerous global warming is happening, is unequivocal, is rapid, is irrefutable, is unprecedented, is robust, is significant and is accelerating can only be one thing: he or she is a pathological liar.
HadCRUT is the IPCC's gold-standard for measuring global temperatures - over last 15 years (180 months) the globe has cooled with a -0.24C per century trend, not warmed as predicted
(click image to enlarge)
HadCRUT released their latest global temperature dataset today, which confirmed what both NOAA and NASA reported earlier this month - that global temps declined during July 2012.
In addition, the plot of the HadCRUT and CO2 data for the last 15 years, through July 2012, is very revealing.
Contrary to what the mainstream press reports and exaggerates about
"global warming," the world has actually been in a stable-to-cooling
phase since the El Nino temperature spike of 1997/98.
Of course, if the NYTimes or WAPO or CNN or CBS or the AP were ever to report the actual cooling trend over the last 15 years (despite the massive amounts of human CO2 emissions) this would establish that they have been grossly misleading the public for years about consensus "global warming."
And as the press fully realize, the public that primarily relies on traditional media outlets are extremely gullible with little intellectual curiosity. Thus the media gets away with hysterical fear-mongering, half-truths and deceptions.
Conclusion: Long story short - human CO2 emissions are not causing rapid, accelerating global warming, per the IPCC's favored HadCRUT temperature dataset. Over the last 15 years, global temperatures have been relatively stable, with a slight global cooling trend being exhibited. All the IPCC's and NOAA's climate experts, their climate models and the professional doomsayers have been absolutely wrong about their catastrophic climate predictions, for over a decade now - and not a single mainstream press outlet reports this. Solid advice to gullible: don't believe anything the mainstream press outlets "report."
