We've said it before...climate models can't predict squat...current scenarios of global climate temperatures and level of temp change already reveal a massive failure...policymakers and taxpayers should completely disregard the virtual computer simulations of climate doomsday proposed by UN's IPCC.....

This is not brain surgery. This is not rocket science. This is not nuclear physics.
Climate science fiction: For the last 10 year-period, the UN's IPCC climate models predicted greenhouse global warming equaling a per century trend of 1.7°C.
Climate fact: The globe warmed at only a +0.2°C/century trend. In other words, global warming has stalled, paused, or if one prefers, in a hiatus condition.
Simply put, the computer simulations programmed by CAGW alarmists produced virtual global warming 8 times greater than climate reality.
This spectacular failure by models (developed by the "consensus" experts) is well documented. And as of this date, there are over 50+excuses reasons by these "experts" as to why their billion-dollar climate simulations have turned out to be worthless for policymakers.

For multiple decades, we've been warned by the elites and "experts" that extreme climate change is at our collective doorstep...severe record-setting weather events a common occurrence...CO2 emissions and other greenhouse gases wreaking untold devastation & havoc...climate refugees swamping interior safe havens...and yet, at the end of 2014 the feared devastation, calamities and climate extreme records were still far and few between after 1990.....

The above map depicts the greatest extremes of temperatures recorded and officially recognized as being legit by the World Meteorological Organization (WMO), a UN agency.
The WMO has been an avid participant pushing the climate disaster/catastrophe claims associated with the anthropogenic global warming political agenda. In conflict with their apparent agenda, the WMO happens to be responsible for determining the official records for extreme weather events across the globe.
Ironically, this proponent of CO2-caused weather extremes has officially documented the paucity thereof since the 1990s.
It was during the 1980s that the major national climate agencies and the UN began promulgating the idea that climate catastrophes and extremes were abundant, due to the growing levels of trace atmospheric CO2 emissions. The principal claim being the trace GHGs is causing an evermore hotter world, about to go from calamities to civilization cataclysm.
And as time wore on, the WMO and other "experts" were wrong - it just hasn't happened.
Examine the map closely and it will be noted that the 'newest' hemisphere/continent hot temperature record took place way back in 1978 - it's now 37 years later and we're all still waiting for those new temp extreme records.
One could conclude that the WMO's own official records have not been kind to the global warming scare. Amazingly, the same can be said for many other official weather extremes that the WMO keeps a tally of.
As can be seen, there are many climate records from the past that took place well before the 1990s. We are now into the 15th year of the 21st century and those predicted extremes remain a rare breed.
This should not come as a surprise though. Indeed, the world has suffered from incredible weather extremes, most of which were experienced prior to large GHG emissions due to natural climate and weather patterns.
With that said, earthly records are made to be broken - they always are. However, CO2 and other trace gases do not guarantee new records...but nature does, which the record books are filled with.
Cautionary note to world's elites and climate experts: Over the last 25 years, the world has witnessed multiple times more failed predictions of climate extremes than all the new record-setting weather events - a genuine exhibition of requisite humility may be due.

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.
According to the IPCC, GHG's are well beyond the business-as-usual scenario that James Hansen and NASA identified as leading to global warming "hell" ... big problem with that though.....

This IPCC AR5 SPM chart reveals some very interesting information about greenhouse gases. The chart plots GHG group emissions over the period from 1970-2010. (chart source)
The adjacent 'C3' chart, re-plots the same information using a simple column representation, plus depicting the fitted trend growth for each GHG group's emissions.
Some key points:
1. From 1970 to 2000, total GHG emissions grew by 1.3% per year.
2. Over the period of 2000-2010, that growth increased to 2.2% per year - a robust 70% growth in the annual rate.
3. Total GHG emissions jumped significantly from 2000-2010, to a historical record, with the combined CO2 emission groups being the principal contributors.
5. Methane emissions essentially stalled over 20 years but then started to increase over the last period.
6.Fluorinated gases (hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride), which are supposed to be reduced under the terms of the Kyoto protocol, have increased by 8x since 1970 but still only represent less than one-tenth of one percent of all GHG emissions.
7. Although the growth rate of CO2 emissions from fossil fuels slowed a bit from 1980 to 1990, it's growth started accelerating during the 90's.
8. The combination of CO2 fossil fuels emissions and CO2 emissions from deforestation, forest fires and peat burning have grown from 72% of all GHG emissions in 1970 to 76% of all GHG emissions.
Clearly, and unequivocally, the GHG emissions have not only sustained the business-as-usual (BAU) growth path that so concerns prominent advocates of climate alarmism, but over the last 10 year period the 'BAU' scenario levels for the demonized CO2 have jumped significantly (see top 3 charts on this page)
A little history: The BAU greenhouse gas emissions path was made famous by NASA's James Hansen, whose 1988 Senate testimony introduced the public to the dangerous and accelerating global warming potential of Scenario 'A'. This scenario was determined/computed to be a direct result of not reducing/restraining the GHGs emissions, especially fossil fuel CO2.
From a famous 1988 peer reviewed article by Hansen et al.:
"We define three trace gas scenarios to provide an indication of how the predicted climate trend depends upon trace gas growth rates. Scenario 'A' assumes that growth rates of trace gas emissions typical of the 1970s and 1980s will continue indefinitely; the assumed annual growth averages about 1.5% of current emissions, so the net greenhouse forcing increases exponentially. Scenario 'B' has decreasing trace gas growth rates, such that the annual increase of the greenhouse climate forcing remains approximately constant at the present level. Scenario 'C' drastically reduces trace gas growth between 1990 and 2000 such that the greenhouse climate forcing ceases to increase after 2000."
Switching from that history to the present, as the IPCC documents in the latest AR5 SPM (WGIII), we are living in the emission scenario of unrestrained growth - growth beyond the feared 1988 'BAU'. Hansen defined unrestrained BAU growth of GHGs as 1.5% per year, and now the IPCC reports it's growing at a 2.2% per annum rate.
In the opinion of climate alarmist advocates, this feared 'Beyond-BAU' growth means that radiative forcings (watts per square meter) will dramatically increase, resulting in out-of-control warming, multiple positive feedback loops and ever greater and more frequent climate/weather catastrophes.
And these alarmist opinions are due to the very costly and "sophisticated" IPCC/climate agencies computer crystal balls model simulations - dominated by said CO2 and other trace GHG emissions - that have proven to be such unreliable prediction tools. Recall that those climate model temperature prediction 'Ooopsies' are a major embarrassing problem plaguing the current reliance of climate science on unproven virtual simulations.
Just to add a little more context to the 'Beyond-BAU' fears of accelerating CO2 emissions, there is this article:
"Annual carbon dioxide emissions showed a strong  rise of 2.5% on 2013 levels, putting the total emitted this year on track for 40bn tonnes. That means the global ‘carbon budget’, calculated as the total governments can afford to emit without pushing temperatures higher than 2C above pre-industrial levels, is likely to be used up within just one generation, or in thirty years from now."
Finally, in the IPCC's own AR5 SPM words:
"Total anthropogenic GHG emissions have continued to increase over 1970 to 2010 with larger absolute decadal increases toward the end of this period. Despite a growing number of climate change mitigation policies, annual GHG emissions grew on average by 1.0 gigatonne carbon dioxide equivalent (GtCO2eq) (2.2 %) per year from 2000 to 2010 compared to 0.4 GtCO2eq (1.3 %) per year from 1970 to 2000. Total anthropogenic GHG emissions were the highest in human history from 2000 to 2010 and reached 49 (±4.5) GtCO2eq/yr in 2010.".....
"Without additional efforts to reduce GHG emissions beyond those in place today, emissions growth is expectedto persist driven by growth in global population and economic activities. Baseline scenarios, those without additional mitigation, result in global mean surface temperature increases in 2100 from 3.7 °C to 4.8 °C compared to pre-industrial levels."
Conclusion: The alarmist science community and the IPCC's worst case GHG scenarios have been attained. Yet global temperatures (i.e. accelerated warming) have not responded accordingly. As one could surmise..."something is rotten in the state of computer climate science."
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.

Note: UK CET monthly temperature dataset can be downloaded from here.

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.

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!

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? It's easy to produce charts - you can do it too! Go here to learn how.
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.
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.
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.
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..."

Another IPCC climate model prediction fails the ultimate test...it's confirmed that the computer simulations of increased flooding did not materialize...and human CO2 emissions do not cause more and bigger floods.....
(click on image for source)
The supposed extreme climate change caused by human CO2 emissions is not producing the predicted increase of intensity and frequency of regional flooding.
A new study conducted by experts comes to an unsettling truth: the consensus climate science of the IPCC, CAGW alarmists and computer models has been spectacularly wrong.
"In a massive review of the subject conducted by a team of seventeen researchers hailing from eleven different countries, i.e., Kundzewicz et al. (2013), we learn the following: (1) "no gauge-based evidence has been found for a climate-driven, globally widespread change in the magnitude/frequency of floods during the last decades," (2) "there is low confidence in projections of changes in fluvial floods, due to limited evidence and because the causes of regional changes are complex," (3) "considerable uncertainty remains in the projections of changes in flood magnitude and frequency," (4) increases in global flood disaster losses reported over the last few decades "may be attributed to improvements in reporting, population increase and urbanization in flood-prone areas, increase of property value and degraded awareness about natural risks (due to less natural lifestyle)," (5) "the linkages between enhanced greenhouse forcing and flood phenomena are highly complex and, up to the present, it has not been possible to describe the connections well, either by empirical analysis or by the use of models," and (6) "the problem of flood losses is mostly about what we do on or to the landscape," which they say "will be the case for decades to come.""
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.
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.
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.

The huge failure of "expert" climate science goes all the way back to the IPCC's genesis: its 1990 predictions provide the 99.9% proof that their global warming fear-mongering is without scientific merit.....
(click on chart to enlarge)
Climate reality and actual evidence-based science has completely eviscerated the global warming claims of the IPCC's "scientists" and those in the "consensus" choir.
Recent climate change predictions produced by the latest bleeding-edge computer models have proven to be spectacularly wrong.
Longer-term proof that the IPCC (and its climate-doomsday religion acolytes) is provided by the original "expert" predictions that were first published back in 1990. That proof is clearly obvious from the accompanying chart.
Simply stated: the IPCC predicted that if human emissions of CO2 kept growing in a business-as-usual (BAU) manner, the world would experience a high likelihood of global warming acceleration - to a per century rate of 2.8°C.
Instead, as the chart depicts, global warming since 1990 has achieved only a 1.4°C per century rate, per the global-wide 24/7 measurements of satellites. Yet the BAU growth of human emission tonnes actually accelerated to a 13.2% annual rate for the 10 years ending 2013. Those are the stubborn facts that are indisputable, unequivocal and irrefutable.
This cataclysmic failure of orthodoxy, green religion-based, climate-science-doomsday predictions is now being referred to as one of science's biggest mysteries - a confirmation of 99.9% proof one could surmise, and the public reportedly agrees with.
And let's not forget the proof that the doomsday climate scientists are confirming their own spectacular prediction failures with the recent plethora of excuses.
Whether the "experts" are the IPCC's climate models or associated scientists, their climate predictions for Northern Hemisphere snow extent, i.e., square kilometer coverage, have been robustly wrong...
(click on chart to enlarge)
The IPCC has become globally infamous for their atrocious climate change, global warming predictions (read brief summary).
There are multiple examples of the up-to-date empirical evidence confirming that the IPCC's doomsday climate predictions are without merit - here, here, here and here are just a few examples.
And at the close of March 2014, it is now possible to compare the latest empirical evidence versus the IPCC "expert" prediction that human CO2 emissions would severely reduce snow coverage across the Northern Hemisphere during winter months (December, January, February and March).
As this accompanying chart obviously indicates, snow extent has actually increased over the short term (see 3-year average curve); and since the beginning of the dataset, winter snows have ranged within a narrow band.
During any given year's winter, there are periods of extremely large snow extent, soon to be followed by low extremes. This natural variation occurs despite the growing surge of CO2 emissions, as denoted by the methodically increasing black step-curve.
For many regions of the Northern Hemisphere, the past several winters since 2007 have witnessed brutal winters of extreme snow and cold, which the upsurge of the chart's 3-year average curve corroborates. As additional corraboration, there is the actual global sea ice growth that also mocks the "expert" IPCC predictions.

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.

Other IPCC consensus "experts" are wildly throwing around a hodgepodge of reasons that at last count was up to eight. Take your pick.
One reason definitely not on the table for discussion by climate reality deniers resisters is the obvious one: increasing CO2 levels are having little impact on global temperatures, which means that nature's normal climate forces overwhelm any CO2 influence. For the consensus scientists to open this can-of-worms would be the death knell of the AGW hypothesis - scientists driven by greed and the limelight do not willingly eviscerate the golden ox that has produced multi-billions for research grants and scientific studies.
Yet, when scientists examine the empirical temperature measurement datasets, it becomes readily apparent that changes in CO2 levels are not generating the expected changes in global temperatures, as predicted by the immensely powerful and sophisticated (and incredibly costly) climate models.
This obvious climate reality is portrayed in the above chart. Literally, 3-year changes in CO2 levels have no correlation with 3-year changes in global temperatures for the IPCC's modern era, starting with 1950. Simply put, one does not have to be a rocket scientist, nor a climate scientist, to ascertain that the CO2-centric AGW hypothesis is severely dysfunctional.
Eventually, global warming phase will return, as it always has in the past, but the climate models' prediction outcomes (and credibility) will likely be even worse, if that is even possible.
Poll after poll clearly indicates that Americans do not believe the Obama administration's anti-science claims (bogus?) regarding climate change and global warming.
Most Americans understand the day-to-day climate reality, thus they handily reject the climate hysteria and gutter-smears that both Obama and John Kerry feel compelled to utter.
As this accompanying chart reveals, global temperature change has decelerated and is now in negative (ie, global cooling) territory - the pink dot denotes current climate reality during the Obama administration.
This empirical evidence from the UK's climate research agency is the gold-standard, utilized by the UN's IPCC.
The red curve is a plot of 5-year "acceleration" (or lack thereof) presented as 5-year per century trend data-points (based on 60-month linear trends calculated for each month since 1850). The black plot represents a simple 10-year moving average of the 60-month data-points.
Why 5 years? Reality: The Obama administration has occupied the White House for the last 5 years.
What does the chart establish? Reality: Since a peak of warming "acceleration" during the second Bush administration, the short-term global warming trend has collapsed during Obama's term. Indeed, short-term global cooling is the current scientific fact.
How does the current short-term trend compare to previous administrations? Reality: During the modern era since 1950, Democrat administrations under Carter and Clinton reached the greatest warming accelerations (respectively, a 7.8°C/century trend during 1980 and a 8.4°C/century during 1998).
For comparisons sake, those 5-year acceleration peaks exceeding 5.0°C/century have been labeled on the chart with their respective White House occupants. And note, the greatest global warming short-term accelerations took place prior to 1950, plus being prior to the large influx of post-WWII consumer/industrial CO2 emissions.
When should a future president and the public become concerned about global warming caused climate change? Reality: When warming finally exceeds the unprecedented per century trend rate (11.5°C) previously reached during the Rutherford Hayes administration (1877-1881), for an extended period (say, 2 years as a minimum).
Again, the pink dot on the chart tells the climate science reality: Per the empirical evidence, the recent White House anti-science climate change comments are blatantly false, without any scientific merit, and are deserving of multiple Pinocchio badges.
More climate science reality: Those modern global and regional temperature charts that don't lie.

Scientists associated with the UN's IPCC predicted that the huge consumer/industrial emissions of the modern era would cause not only "unprecedented" global warming but also dangerous "runaway" warming, which would then produce "tipping point" climate change.
The climate science consensus today is that these speculative climate forecasts, based on flawed computer models, did not happen and expert analysis of the gold-standard of temperature datasets (the UK's global HadCRUT4) confirms it.
As this adjacent chart reveals, modern warming increases over the last 60 years don't even match the warming increases of the prior 60-year period, when earlier human emissions were just a fraction of contemporary amounts. (The vast difference of increases for atmospheric CO2 levels, between the two 60-year periods, is depicted on the chart - an 18ppm increase for the earlier period versus an 82ppm increase for the modern 60-year period.)
The climate science fact that huge modern CO2 emissions did not generate the expected runaway warming over the long-term, nor even over the shorter-term, now has the establishment science journals questioning the obvious - how was the IPCC so wrong?
And this empirical evidence refutation of conventional climate science has become so glaring, that even the traditional mainstream press is finally taking notice that something is truly amiss regarding the IPCC's climate science orthodoxy.
IPCC scientists assume that human CO2 emissions will continue to accumulate in the atmosphere, remaining anywhere from hundreds to thousands of years.
This assumption is a cornerstone of the AGW hypothesis. The cumulative CO2 growth causes global warming that accelerates (they hypothesize) to a condition of "runaway" temperature increases via positive feedbacks, leading to catastrophic "tipping point" climate change.
To simplify, the CO2-centric AGW hypothesis, and climate models, assume that every additional emission molecule of atmospheric CO2 will accelerate the global warming, to the point of no return. Thus, each new tonne (metric) of CO2 will boost the acceleration via a theoretical positive feedback amplification.
But does the empirical evidence actually indicate that is indeed what is taking place?
Using a combination of the NOAA annual global temperature dataset and two sources of global CO2 emissions from fossil fuels, it can be determined how each new tonne of CO2 emissions is "accelerating" temperatures, or not.
This article's chart provides the answer. As can be observed, each new CO2 emission molecule added to the climate has a smaller and small impact, the opposite of the AGW hypothesis. In 1941, the degree increase per tonne hit a peak. Since then, the impact of each tonne has decreased, significantly - currently it stands at +0.00000000000021°C/tonne.
The AGW hypothesis does not account for this ever smaller impact of CO2. Possibly this is the reason for the "consensus" unexpected global warming 'hiatus', which the IPCC scientists are still at a loss to explain.
If this tiny impact stays constant over the next 30 years, and the growth rate of CO2 emissions over the last 15 years remains the same for the next 30 years (another trillion tonnes emitted), the potential increase of global temperatures will barely be +0.2°C (two-tenths of a degree) by year 2044. And if each tonne's impact continues to shrink, as the evidence suggests, so will the temperature increase shrink.
Now, adding to this miserably low warming influence of CO2 is the recent admission by establishment climate science that natural climatic forces have a powerful say in the trend of global temperatures, regardless of human CO2 emissions. As the Nature science journal indicates, currently, and for the near future, a natural PDO cooling phase may dominate.
More on the above 'C3' chart. Specifically, it plots a ratio of 30-year NOAA temperature changes to the cumulative amount of CO2 tonnes emitted up to that point. For example, the 1941 ratio has a numerator of +0.59°C (30-year annual temperature change) and a denominator of 165 billion CO2 tonnes (the cumulative amount emitted from 1880 through 1941). This ratio calculation is made for each year, starting with 1910 (30 years after 1880).
The ratio allows for depicting visually the influence of all those previous CO2 emissions on moving 30-year climate periods. The chart's additional green and light blue curves simply provide a smoothed sense of direction of the fossil fuel emission influence.
Summary: The observed shrinking of CO2's influence on global warming does not bode well for the future longevity of the AGW hypothesis. Per the well known and documented CO2 physics, this outcome should not be a surprise. It's just another case of 'those stubborn facts' in science.
There is an enduring myth that global temperatures are accelerating, produced by ever greater amounts of human CO2 emissions released into the atmosphere. The myth is popularized by anti-science propagandists, who are either driven by political agendas or irrational fears.
The myth facilitators actually claim that the world is currently experiencing rapid and dangerous global warming. This ludicrous claim is completely counter to all known empirical, scientific evidence.
At least 97% of climate scientists would not make this claim, since it is well established that global temps have stalled for 16+ years, and even the most pro-AGW scientists are now admitting that the lack of warming is likely due to natural forces.
The enduring myth of "accelerating" is a leftover from earlier IPCC climate reports and the original AGW hypothesis that speculated greater levels of atmospheric CO2 would generate "runaway" global warming leading to a catastrophic "tipping point" climate change. That's how 'AGW' turned into 'CAGW'.
Well, neither has happened, which the indisputable and unequivocal evidence is clear about.
The above chart plots the changing 3-year linear trend slopes using monthly observations going back to 1850 (this is the HadCRUT4 dataset from the UK climate research agency - it is the only global dataset going back that far).
The plot clearly shows that temperatures will achieve short-term accelerations, both cooling and warming. The evidence also shows that any acceleration is a temporary phenomenon that then is reversed. The greatest period of accelerating warming took place during the late 1870s when a short-lived +23.4°C per century pace was reached.
The greatest acceleration for the modern era was reached in 1998 (+17.5°C per century rate), some 6 degrees below the earlier record a 100+ years before. The 1998 peak was a direct result of natural climate forces, the super El Nino of 1997-1998.
The chart also includes a 3-year average plot of atmospheric CO2 levels, which reflects a never-ceasing growth (exception being WWII years).
Obviously, to the eye, the level of CO2 has no relationship with "accelerating" cooling or warming. The statistical correlation between CO2 and acceleration level is barely above zero - an indicator that the agenda-driven myth has absolutely no empirical legs, so-to-speak.
Finally, the chart has a 120-period (10-year) average of the 3-year per century trends of acceleration/deceleration. This dark curve has a black circle around the 2013 endpoint. Simply put, accelerating, rapid warming is not happening presently (but rest assured, it will happen in the future, just like it has in the past - and that's what natural climate change does, no human CO2 required).
Recently, the world's major climate agencies published their year-end empirical datasets for global temperatures.
How does actual climate reality compare with the IPCC's 2013 proclamation that their "extremely likely" predictions of global temperatures? With 95% certainty, embarrassingly bad. (click on chart to enlarge)
The chart on the left is a plot of the IPCC's RCP4.5 model output versus the climate reality, as represented by the UK's HadCRUT4 global monthly temperature dataset. The bright red and blue curves are simple 3-year moving averages that visually removes all the monthly gyrations.
It is clear that the IPCC's state-of-the-art 2013 climate models start diverging from climate reality around the 1995 period. And the divergence continues to widen to the point where one could conclude that any future output will be extremely unlikely to be of any value to policymakers.
Put another way, these billion-dollar, taxpayer-funded super-computer model simulations have performed atrociously, and are entirely worthless at predicting future climate scenarios.
How did this happen?
While the IPCC's associated climate "experts" are going through their own set of mental gyrations to explain the abysmal climate model and AGW hypothesis performances, two scientists explain how this failure was produced - article number one and article number two.
If you are curious as to the 'whys' of IPCC climate consensus failure, these articles are a must read. For those short on time, though, in a nutshell a compiled summary of reasons for failure:
natural climate variability ignorance
de-emphasis of large uncertainty
dogmatic co2-AGW orthodoxy
Until the above are adequately addressed and fixed, the probability that climate models will predict with accuracy that policymakers can actually rely on is extremely unlikely, with 99.9% certainty.
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.
The 2013 climate reality has been a harsh mistress to those cult doomsday scientists and proponents who constantly embarrass themselves by denying the actual climate evidence.
While this latest "global warming" PR nightmare exposes the absurdity of the doomsday cult science, the new IPCC climate report ('AR5') continues to promulgate the doomsday, anti-science scenarios for the news media. Yet, this latest report has quietly moderated the long IPCC tradition of climate reality denial.
Analyzing the IPCC's latest publication details found deep inside the the AR5 report (which the mainstream media always fails to read), the IPCC has been forced to lower their global warming temperature predictions "projections."
Essentially, the IPCC's long denial of non-catastrophic warming has been mugged by climate change reality.
The above chart (click to enlarge) depicts the robust and significant lowering of the IPCC's predictions regarding human CO2-induced global warming. Despite being forced to drop their medium assessment down to a a rather low +1.7°C per century trend, the actual empirical evidence, from both the land/sea surface and satellite atmospheric observations, indicates that the IPCC will again be forced in the future to lower their predictions projections even further.
Due to the climate reality of observed per century trends, ranging from 0.0 to +1.1°C, the next ratchet down by the IPCC may be in the 1.25°C per century realm.
Unfortunately, for many years the IPCC has successfully practiced climate reality denial, with the gleeful support of mainstream science "journalists" who just love their climate disaster porn. No longer, though, it would seem.
The climate change realists are now forcing objective scientific analysis on both the climate-doomsday, anti-CO2 cultists and the big government funded scientists who promote that fringe anti-science agenda. It's a welcome change - the global audience is finally learning the truth about the real climate change and the actual lackluster global warming.
The IPCC's catastrophic AGW (CAGW) hypothesis is based on the prediction that human CO2 emissions would produce a "hotspot" in the atmosphere above the tropics. This hotspot was identified by the IPCC as the penultimate evidence that global warming was accelerating, causing a "tipping point" cascade of catastrophic events.
The projected hotspot over the tropics was expected to stretch from the 5km mark to as high as 15km, with the hottest portion being from 8-12km. The temperatures in this specific area were supposed to rise 1.2 to 1.5 times faster than surface temperatures, due to positive feedback loop produced by the CO2-induced warming.
Big problem though. As this chart of the lower troposphere (over the tropic latitudes) documents, NASA satellites are unable to locate this mysterious, runaway "hotspot" (AGW "signature" and/or "fingerprint") that the IPCC and global warming alarmists have long predicted. This despite NASA satellites having 100% coverage over the entire tropical troposphere, including the critical water vapor areas of the lower and mid-troposphere.
In fact, this specific area of the troposphere has only warmed a fraction of the IPCC's predictions, turning the "hotspot" into the embarrassing "AWOLspot." Additionally, this means that the feared AGW positive feedback loop went kaput, or it never really existed, except in the "consensus" hive mind of the alarmist-science collective.
Additional chart info: the red-dotted curve is a basic 36-month moving average; the green curve is 6th order fitted trend of monthly measurements; and the grey area represents the cumulative per cent growth of atmospheric CO2 levels. (Since satellite monitoring of atmospheric temperatures began, the cumulative growth of CO2 ppm levels has been over 18%.)
Per this satellite empirical evidence, the existing linear temperature trend of the low-troposphere tropic latitudes is ludicrously small, indicating that 2100AD temperatures may only increase by +0.6°C (necessary warning: trends are not predictions, don't go there). For the mid-troposphere tropics, the trend is even lower, +0.3°C. Compare those low trend rates with the modest warming trend of the entire atmosphere: +1.2°C by 2100AD.
And the comparison to the surface temps? NASA/GISS has a linear trend for the same time period projecting an outcome of +1.3°C by 2100AD.
Yep, you read that correctly. The tropical hotspot trends are lower than the global atmospheric trend and the global surface trend - a magnificent and spectacular fail of IPCC climate "science."
The simple, indisputable, scientific summary after 35 years of empirical evidence: The tropical, runaway hotspot did not happen in spite of massive amounts of CO2 emissions released into the atmosphere; ergo, the IPCC was wrong, again; the billion-dollar climate model predictions were wrong, again; alarmist, agenda-driven scientists' claims of climate doomsday were wrong, again; and, the fanatical anti-CO2 green lobby was wrong, as always.

The IPCC's climate science has long claimed that human CO2 emissions are producing an accelerated global warming, with a "runaway" warming trend, which is then being amplified in the north and south polar extremes. This dangerous warming is, of course, causing the ice sheets to melt, unleashing catastrophic sea level rise, and thus swamping coastal regions and low-lying islands, as we speak!
Hmmm.....despite over 845 billion tons of human CO2 emissions being added to the biosphere since 1978, that predicted dangerous warming, and associated catastrophes, have yet to materialize.
A BIG-TIME FAIL, no? As many are now saying, a rather robust and very significant embarrassment for all of the "consensus" involved: including the IPCC, the United Nations' science "experts," the governing elites and bureaucrats.
This huge fail is amplified because the South Pole region that includes Antarctica has done the opposite - literally a cooling temperature trend over the last 35 years.
NASA's satellites have now been measuring global temperatures for a full 35 years (420 months through November 2013), including the Antarctic. The above chart documents the measured southern polar region temperatures.
As can be seen, there has been a cooling trend - granted, a very tiny -0.04°C/century, but it remains far removed from the IPCC's unicorn science of "amplified" and dangerous polar warming.
And not only has it not warmed, the Antarctic sea ice has grown to a record amount.
Well, you might now be wondering if that imminent, catastrophic Antarctica ice sheets melting and collapse are still imminent...as predicted. Nope. Eating a huge amount of that cooling crow, the IPCC has recently labeled that outcome as "extremely unlikely".....Ooops!!
In summary, those stubborn facts that are the archenemy of climate change alarmists are without mercy - after 35 years of high tech measurements, the South Pole region has nada, zilch, goose egg, naught, aught, nil, nix, nothing, null, zero, zip and zippo warming. Nuff said.
Simply put, the IPCC's climate models and experts are unable to predict cloud formation and coverage, which makes accurately predicting climate conditions an impossible task.
As a result, the models have huge problems with predicting actual polar sea ice coverage and albedo characteristics - a continuing major fail that shreds the IPCC's creditability as a reliable source for climate fearmongering prognostications.
This latest study confirms that the state-of-the-art climate models have proven to be no better at predicting Arctic clouds and sea ice than their grossly inaccurate predecessors.
And as these plots (source) of polar sea ice indicate, the global sea ice area and extent exhibit an increasing trend that is the polar opposite of the IPCC's those fabled "expert" predictions.(bad pun intended)
It is now an indisputable fact that the IPCC's "dangerous", "accelerating" and "tipping point" global warming has gone completely AWOL. This has been well documented empirically, as this temperature chart through October 2013 reveals.
Does this now mean global warming is kaput, in permanent hibernation? Nope.
But it does mean that the IPCC's climate scientists were wrong about future global warming, and that the consensus is now changing due to actual climate reality.
Serious discussions about global cooling have become the reality, much to the chagrin of climate "experts" and IPCC cohorts who have wasted multi-billions on the global warming hysteria.
The scientific pivot to cooling confirms what many have thought and said over the last few decades: human CO2 emissions do have a warming influence on global temperatures but, with that said, it is a minor factor that is easily overwhelmed by both solar/cosmic and natural earthly forces. Apparently, the CO2 impact is so weak it is unable to stop this unexpected (by the IPCC) cooling momentum that could wreak havoc on agriculture and economies.
The adjacent plot (click on chart to enlarge) of global HadCRUT October temperature anomalies from two different periods clearly documents the minor impact of human CO2 emissions.
The IPCC claims that since 1950 global temperatures have been driven by the massive human CO2 emissions. Yet when one examines the October temperature records, it is found that the last 64 years of global warming (1950-2013) is very similar to the global warming pattern for the 64-year period ending in 1949.
The chart's two ten-year moving average curves for the respective periods indicate a similarity that is striking, especially considering that modern human CO2 emissions are many multiples larger than the pre-1950 emissions. Adding to that similarity is the fact that the linear trends for October temperatures are almost the same - only an 18/100ths difference if both trends were extended out the 87 years to October 2100AD.
Indeed, a portion of that small linear trend difference might be due to human CO2 emissions; or, then again, it might be due to the vast urbanization effect over the last 60+ years; or due to the large deforestation that's taken place; or, maybe it's entirely due to the serial fabrication of global warming by the world's climate agencies; or it's even possible that the post-1950 warming was entirely a natural phenomenon - the same as the prior 64-year period experience.
Climate reality and the IPCC's predictions often wildly diverge. The well understood reason for this divergence is simply a result of the UN's political agenda, pushed aggressively by its bureaucrats and sponsored "scientists".
An example of its agenda science is shown in the adjacent plot of actual sea level rise versus 2100AD predictions. (click plot to enlarge)
At the bottom of the chart is the plot of actual sea level rise calculated by Colorado University using satellite measurements. Per this empirical evidence, the sea level trend since 1992 suggest that oceans will rise some 11 inches by 2100AD.
An 11" rise by century-end is definitely not a catastrophe and certainly an outcome that humans can adapt to/cope with. And clearly, it represents a 2100AD level substantially below the IPCC's predicted 24" rise.
The IPCC's prediction not only does not comport with climate reality, other expert research indicates that sea level rise by 2100AD will amount to only a 4-6" increase. Two recent studies, one by NOAA and another by China's experts, represent 'those stubborn facts' that are continually undermining the IPCC prediction fantasies.
When assessing future climate forecasts, it's best to remember that the IPCC's "scientific" reports are climate exaggerations produced by their mandated UN political agenda. Climate science reality is an entirely different animal, though.
Not only have the IPCC climate models performed poorly on a global basis, their predictive skill capability on important regional climates approach being abysmal also.
As this new peer reviewed study concludes, the models being used to predict sea surface temperatures for the tropical Pacific have produced results that have standard deviations of some 200% stronger versus observed measurements since the Super El Niño of 1997/98. Not good. Confirms previous studies of climate models.
Essentially, the demonstrably large failures of both global and regional climate models represent a systemic failure created by those consensus "experts."
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.
Steve McIntyre analyzed the Southern Hemisphere historical temperature information contained in the recent IPCC AR5 report and documents an amazing discovery.
Extreme, absurd cherry-picking that defies objective, impartial science.
In essence, the IPCC's representation of Southern Hemisphere temperature changes is biased with unrelated Northern Hemisphere paleo-temperature datasets; the IPCC ignores established, widely accepted Southern datasets such as Antarctica's ice core evidence, as displayed here (click on image to enlarge).
Not only does the IPCC avoid utilization of the the inconvenient Vostok ice core temperatures that reveal the Medieval Warming period for the Southern latitudes, they chose to use Northern datasets that have been widely criticized for being error-filled and massively manipulated via questionable, non-standard statistical techniques.
Like previous IPCC reports, the AR5 edition obviously shares the agenda-science traits of absurd cherry-picking, gross misrepresentations and ludicrous fabrications, which confirms the accusations that green-alarmists have completely corrupted climate science.
Note: As the chart depicts, the polar region of the Southern Hemisphere has exhibited an overall cooling trend over the last 5,000 years, with multiple peaks and valleys. This persistent cooling trend is also evident from the Greenland ice core dataset. While the polar regions share many temperature change similarities, their warming/cooling phases occur during different years/decades with different amplitude - i.e., narrowly speaking, perfect synchronization of polar climates does not exist.
First, a generic wind stress definition is in order.
surface roughness (i.e., turbulence) as measured by satellite technology, is
referred to as 'wind stress' in climate models. In plain-speak, it is sea surface turbulence, obviously
driven by wind speed and direction, in addition to being impacted by atmospheric density/pressures, sea surface
temperatures, sea buoyancy and currents. Wind stress affects the air-sea heat exchange,
as well as the mixing of carbon/heat stored in the deeper parts of oceans. Wind
stress also has impacts on cloud cover, ocean current circulations and sea ice
In essence, wind stress is a powerful and critical elemental
influence on the world's climate. Thus, to forecast future climate conditions
with any sort of accuracy, it is absolutely necessary to be able to accurately simulate
As this latest peer reviewed scientific research reveals,
all climate "experts" and the IPCC's climate models remain unable to
accurately simulate wind stress on their massively expensive, sophisticated,
complex computer models.
As has been noted by publications across the world, the new IPCC AR5 report confirms that the past catastrophic global warming alarmism, relentlessly pushed by the IPCC community, is essentially without scientific merit.
From the editors of the Nature journal comes this scathing comment about the new report:
"Scientists cannot say with any certainty what rate of warming might be expected, or what effects humanity might want to prepare for, hedge against or avoid at all costs. Despite decades of research funded by taxpayers to the tune of billions of dollars, we are no more certain about the impact of man-made greenhouse gases than we were in 1990, or even in 1979 when the National Academy of Sciences estimated the effect of a doubling of carbon dioxide to be "near 3 degrees C with a probable error of plus or minus 1.5 degrees C."
And of course, there is the amazing admission in the 'AR5' report that those soon-to-be, just-around-the-corner climate disasters, that were repeated ad nausem over the last two decades, are no longer on-the-table, so to speak.
And adding to the IPCC's misery, the latest scientific empirical evidence is not kind. The alarmist hypothesis that human CO2 emissions are similar to a furnace's "thermostat" or a "control-knob" has proven also to be a pseudo-science claim, which actual scientists now consider an embarrassment best forgotten.
Regarding that "thermostat" claim, the above plot of the satellite temperature dataset confirms that even 3-year CO2 changes have apparently zero impact on on 3-year changes. (As previously noted, the last 15 years of global temperature change has revealed a zero impact from changing monthly CO2 levels during that period.)
This chart also includes a plot of human CO2 emissions in gigatons since 1981. Clearly, the gigantic-sized annual emissions are not affecting temperature change, as measured by the satellites. With that said, the exhibited increasing 3-year change of atmospheric CO2 levels may indeed be a result of growing tonnage of human emissions.
In summary, the IPCC's alarmism climate "science" has been torpedoed by its own report and admissions, as well as being completely undermined by the actual empirical evidence. This has not only been recently recognized by the mainstream press, but now the major scientific journals supporting the "consensus" view have finally taken note.
Note: Datasets plotted in this Excel chart can be located here. The temperature and atmospheric CO2 level plots represent 36-month (3-year) changes (e.g. subtract the September 2010 temperature anomaly from the September 2013 anomaly). The dark black, grey and bright red curves are second order polynomial fitted trends produced by Excel - they are not predictions, but they do indicate the current direction the trends are taking.
New research discovers ancient tree stumps that existed under an Alaskan glacier for thousands of years.
The retreating glacier confirms that climate temperatures were much warmer from at least the Minoan period to the Medieval era.
At some point, the climate became cooler and the actual trees were snapped at the stump level, then buried in the glacier's ice for centuries. Finally, the stumps were revealed as the climate returned to warmer temperatures in the rebound from the Little Ice Age.
This actual climate evidence is corroborated by the empirical ice core dataset from Greenland. As the ice core empirical evidence depicts, the ancient periods of the Minoans, Romans and the Medieval era were warmer than the present.
This Greenland evidence also reveals that temperatures have been in an overall cooling phase for the last some 3,500 years, which eventually led to the global glaciers' growth that ultimately would bury trees and forests, such as Alaska's Mendenhall glacier described in this article.
This new research adds to the mountain of empirical evidence and studies that refutes the IPCC's claim that modern temperatures (i.e., global warming) are "unprecedented".
Hmmm...the IPCC climate "science" always seems to be contradicted by those stubborn facts, no?
The principal reason they did not address the temperature empirical evidence, as represented in this plot of the data, is that any rational and objective explanation completely undercuts the shaky foundations of the CO2-AGW hypothesis.
The plotted data clearly shows that the previous modern global warming has shrunk to an insignificant per century rate, and may continue to decrease over the near future. This occurs while the levels and growth of atmospheric CO2 continue a relentless climb.
It has been widely noted across the entire blogosphere
(and even the mainstream
press outlets) that the IPCC AR5 summary report avoided the very uncomfortable
truth that modern global warming has gone literally AWOL over the last 15+ years, and the associated
IPCC climate models' spectacular failure to predict
this non-global warming environment.
Understandably, the IPCC's political bureaucrats don't
want to shine a light on their previously claimed "irreversible",
"incontrovertible", "irrefutable", "unequivocal",
"indisputable", "relentless", "dangerous" and
"accelerating" CO2-warming that has turned into the unprecedented
The IPCC's lack of analysis regarding this 15-year
"pause" was replaced with an attempt to obscure the current temperature reality with a laughable decadal
analysis. 'C3' previously
commented on the lameness of the IPCC's decadal 'smoke and mirrors' as did others
The IPCC's decadal approach to relied on 'decadal means.'
There are other approaches, including analyzing decade-end
temperatures, decadal-trends as shown
here or by examining the moving 10-year (decadal) periods.
(click on image to enlarge, sources for HC4 and CO2 data)
In this article, we look at the moving decadal spans
since January 1, 1950 through August 2013 (the IPCC states that at least 50% of
the warming is due to anthropogenic reasons over this 764-month period) versus
the previous 764-month period (May 1, 1886 through December 1949) that the IPCC
infers was dominated by natural climate forces.
From the two 764-month periods, it is possible to
generate 645 moving 10-year average data points for both the modern era and the earlier 20th century period. The
above two charts plot the moing decadal data points for both periods.
Per an examination of the 10-year moving averages for
each time span, there are several points of interest, including:
the vast differences between the two period's absolute CO2 levels and growth
rates, the warming characteristics of the two periods are more alike than
ten-year curves, and their respective 2nd order fits, visually share similar
characteristics such that one could easily and safely conclude that the modern warming was simply a repeat of the
earlier period's warming (note: recall,
the IPCC states that the earlier warming was not due to anthropogenic reasons).
10-year moving average curves reveal that both the earlier and modern periods
experienced a cooling phase, then a significant warming phase prior to leveling
out to a plateau (a 'hiatus') close to the end.
warming phase during the modern era was 417 months in duration; the early 20th
century period had a warming phase of 397 months (only a 20-month difference).
on 10-year moving averages, the earlier warming period produced a +0.75°C per century trend, which is not that terribly
different than the modern warming of a 1.16°C per century trend.
modern warming were to revert to the earlier warming trend (after the "hiatus"), by year 2100AD
global temperatures would increase by +0.65°C. In contrast, a continuation of
the modern warming trend would produce an increase of +0.99°C, just one-third
of a degree greater.
comparing the differences between the lowest to highest 10-year average
temperature for each warming period, the modern change was less than one-tenth
modern era's CO2 level absolute increase and linear trend growth were both
approximately 5 times greater than the earlier periods respective values.
the earlier period's degree change per ppm was over 3 times greater than that
experienced during the modern warming.
Obviously, this type of decadal analysis reveals an
abundance of similarities shared by the two 20th century warming periods. In
fact, this analysis makes it clear that over 50% of the modern global warming
could be a direct result of the same natural climate forces that warmed the world
prior to the 1950s.
This analysis also directly contradicts the IPCC's
anti-science terminology ("irreversible", "incontrovertible",
"irrefutable", "unequivocal", "indisputable",
"relentless", "dangerous", "accelerating" and
"unprecedented") used to
describe the modern era of warming. Simply put, none of these descriptors are
accurate - they are without any empirical scientific merit.
Unsaid in this analysis (and the IPCC's) is that portion
of modern warming associated with anthropogenic factors is not exclusively due
to CO2 and other greenhouse gases. Other anthropogenic forces causing increases
includes a wide spectrum of land-use issues, black soot pollution, 'slash and
burn' deforestation practices, the urban heat island (UHI) effect, poorly sited
climate/weather stations, the egregious fabrication
of modern global warming by governmental climate agencies and other factors.
Finally, this decadal analysis reveals the absolute known
physics of CO2-induced warming: per the actual physics, it has been established
that the climate response (i.e. global temperatures) is logarithmic.
This means that the earlier rises of atmospheric levels (ppm) of CO2 have
a much greater impact on the climate than the later CO2 increases (ppm).
As the charts detail, the CO2 impact on temperature
degrees was 3 times greater during the early warming than the modern warming
(+0.23°C per CO2 ppm
versus +0.007°C per
CO2 ppm). This confirms the actual climate science physics, while at the same time pretty much
demolishing the fears of the totally speculative, failed and unsubstantiated
"positive feedback" physics that alarmists continue to rely on.
The prediction failure rate of the IPCC and global warming alarmists has simply been astounding.
It is highly certain, at least a 95% certainty, that there has never been an organization so inept at predictions.
The latest prediction failure is one that states that as the earth warms, the world's peatlands would release their sequestered CO2. This release would then unleash a climate positive feedback, thus warming the world even further.
As this new study discovered, per the empirical evidence, as the earth warmed, even more CO2 was sequestered in the peatlands - the direct opposite of the IPCC alarmist community prediction. Absolutely zilch positve feedback took place
In a nutshell, the "policymaker community" is the bureaucracy-engine that is responsible for all the lies designed to mislead the public, journalists and elected officials. To accomplish this, the IPCC bureaucracy utilizes "decision-based evidence making", which is explained in this short video. (video source)
The well documented lack of global warming over the last 15+ years has proven to be a major problem for the latest IPCC AR5 report.
In prior reports, the IPCC has utilized short-term warming as proof that greenhouse gases were the cause, and supposedly proved climate model accuracy. But in this report, the IPCC dismisses the latest 15-year period as being too short to rely on.
Despite this dismissal, the IPCC AR5 report does make an attempt to explain why global warming went AWOL. One of the reasons they state is that global warming decided to dive into the ocean depths where it is currently hiding (and somehow also escaped original detection).
The "hiding" excuse has been picked up by mainstream science journalists without their doing any due diligence on the veracity of the IPCC statement or at least reviewing the actual empirical evidence.
"It’s clear science journalists need some help. The IPCC are saying “The ocean ate my global warming” and most environment reporters just cut-n-paste this excuse — they fall for the breathtaking joules-to-the-22nd-figures — not realizing they convert to a mere 0.07C over nearly 50 years (as if we could measure the average temperature of the global oceans to a hundredth of a degree!). Worse, the warming we do find is so small, it supports the skeptical calculations, not the IPCC’s ones."
A number of experts have analyzed the "global-warming-is-hiding" claim and found it to be, at best, laughable. To add to the bogosity, the IPCC and other serial climate-change exaggerators have attempted to hide the real impact of global warming on the oceans by using a 'gazillion-bazillion' Joules to portray the gain in ocean heat.
A common way they have expressed the effect is to state that it has increased by an approximate 2.0*1023Joules (or, 200,000,000,000,000,000,000,000 Joules). But when converted to actual temperature warming, that number, with all those zeros, equates to about a total of +0.06°C to +0.07°C increase since 1955.
Laughable, no? This level of warming is barely even measurable and irrefutably indicates that CO2 emissions have barely impacted the top 2000 meters of the oceans.
The adjacent three graphs (click to enlarge) depict the warming that has occurred in degrees, as well as Joules. For more information about these charts, done by experts, go here, here and here.
And their work is confirmed by no less than NOAA:
"For the upper 700m, the increase in heat content was 16 x 1022 J since 1961. This is consistent with the comparison by Roemmich and Gilson (2009) of Argo data with the global temperature time-series of Levitus et al (2005), finding a warming of the 0 - 2000 m ocean by 0.06°C since the (pre-XBT) early 1960's."
In addition, the list of articles addressing the IPCC's gross misrepresentation of ocean warming (the "hiding" bogosity) is growing: read here, here, here, here and here.
Note: A 'gazillion-bazillion' is not recognized as a real number. FWIW, a number with 23 zeros does fall between the 'sextillion' and 'septillion' nomenclature. 'Gazillion-bazillion' sounds better though.
Al Gore has often revealed a fundamental dishonesty about catastrophic global warming and climate change disasters. His fantasies have an unfortunate high correlation with absurd disaster movies.
Recently, he became the laughing stock in the science community with his bogus claim of a new hurricane 'Category 6' measurement being added.
That claim was quickly debunked, and now the new IPCC report (AR5) has essentially debunked most of the hysterical climate disaster claims made by Gore et al.
Per climate scientist Judith Curry's analysis of the IPCC's new AR5 report and confirming what others have found:
"But the real issue is this. The IPCC approach, using highly damped deterministic global climate models, is incapable of producing abrupt climate change (beyond the melting of Arctic sea ice, which is not irreversible even on timescales of a decade).
The most scientifically interesting, and societally relevant topic in climate change is the possibility of abrupt climate change, with genuinely massive societal consequences (the disappearance of Arctic sea ice and regional forest diebacks arguably don’t qualify here). The IPCC has high confidence that we don’t have to worry about any of the genuinely dangerous scenarios (e.g. ice sheet collapse, AMOC collapse) on timescales of a century. These collapses have happened in the past, without AGW, and they will inevitably happen sometime in the future, with or without AGW."
The recent IPCC 'AR5' summary report was essentially an admission of failure for the catastrophic human-induced global warming hypothesis. The admission was blatantly obvious as the IPCC bureaucrats did not deliver an adequate explanation for the last 15+ years of non-warming, plus they were unable to even establish what current climate science believes the critical climate sensitivity measure to be.
As result, the IPCC had to resort to lame, non-scientific descriptors such as "unequivocal" and "unprecedented" that were without meaningful empirical evidence. Below is an analysis of their supposed "unprecedented" decadal warming, that when dissected, is beyond lame. (click on charts to enlarge)
These two graphs plot decades-ending global temperature and atmospheric CO2 levels. The graph on the left represents decades prior to the 1950s, and the second graph, those decades subsequent to the 1960s.
Some observations based on this empirical evidence:
#1. From the decade ending in 1909, there were 4 decades in a row that the average global temperature was higher at decade-end (the increase from 1909 to 1919 was indeed very small but nevertheless, it was a warming.).
#2. In the modern era, since 1979, there has been only 3 decades in a row that the average global temperature was higher - ergo, the warming prior to the 1950s remains "unprecedented" in terms of decadal duration.
#3. Clearly, the modern era decades (1980s, 1990s, 2000s) CO2 levels jumped dramatically, approximately 50 points, which is over 6 times greater than the CO2 increase during the pre-1950s decades (1920s, 1930s, 1940s)
#4. If the warming trend of the early 20th century had continued (it didn't) until the end of the 21st century (2099), global temperatures would have increased by +1.92°C; yet despite the huge modern era CO2 spike, if the warming trend represented by the last 3 decades continued (it won't), the increase by 2099 would only be +1.72°C.
#5. The IPCC states that prior to 1950 any global warming was due to natural forces - thus, the +0.41°C decadal increase during the early 20th century was due entirely to natural climate forces.
#6. The IPCC states that the modern warming decadal warming, +0.55°C, was at least 50% caused by humans - thus, it is highly likely that natural climate forces were responsible for the other 50%, say a +0.27°C of the modern warming.
#7. If only half of the modern decadal warming is due to human influences, then it is also likely that the human-caused linear trend would represent a warming rate of only +0.89°C, half the modern 3-decade full-linear trend rate of 1.78°C/century.
#8. Put another way, the pre-1950, the all-natural decadal trend rate of +1.30°C exceeds the +0.89°C modern decadal trend attributed to anthropogenic forces (including land-use, the UHI effect, and of course, greenhouse gases).
#9. If one assumes that the modern decadal warming in reality was simply a cyclical repeat of the early 20th century decades of natural warming, then in actuality, at best, the gigantic increases of CO2 levels were only responsible for maybe a mere +0.14°C increase (+0.55°C - +0.41°C = +0.14°C) over the 3 decades ending in 2009.
Summary: After 7 years of research and billions of dollars on the 'AR5' report, the best that the IPCC can come up with is the thin gruel of "unprecedented" decadal warming, which when examined closely, is a false representation of the makeup, duration and the size of the anthropogenic component of modern warming. Since the last 15 years have proven that natural climate forces simply overwhelm the CO2 impact, the likelihood that modern decadal warming is more a result of natural (non-human) climate forces is the more probable "95% certainty".
