Fortunately, the Titanic only sunk once because engineers and navigators did not continue to make the same mistakes over and over.
But "experts" and climate models provide a never-ending loop of sinking and re-floating of a wide assortment of climate change predictions, forecasts and scenarios.
The weather/climate researchers seem unable to embrace the humility and reality that their computer simulation predictions rarely stay afloat for any length of time before being sent down to deep and cold watery graves.
More specifically, climate model output has been predicting that CO2-induced global warming and climate change would produce more frequent, and more intense, cyclones/hurricanes that would continuously terrorize many coastal populations.
Yet those frightening predictions keep doing a 'Titanic' on the expert model forecasts.
And actually, there is a logical reason for that happening: climate models can't predict squat.
Per the latest peer-reviewed scientific research:
"...Camargo and Wing write that (5) "efforts on modeling improvements, from convective parameterizations to new numerical methods and dynamical cores, also need to continue to occur." And "most of all," as they continue, they say that (6) "what is needed is a better theoretical understanding of what sets the frequency of TCs," noting that (7) "we could make much more confident climate change projections if we had a firmer theoretical expectation of what should happen."
"In conclusion, therefore, they state that (8) "despite the recent advances, there is still need for a substantial community effort to improve simulation of TCs in climate models on all time scales."
Essentially, even after burning through multi-billions of taxpayer monies, the models still can't predict squat due to the inescapable fact that experts require a "firmer theoretical expectation of what should happen."
Message to Trump from climate scientists: "We don't know what we're doing but please send more money anyways, ASAP!"
"Can't predict squat" has become a climate science known ... thus, we have the common climate expert lament: so many predictions, yet so many failures ... but climate science "experts" are not the only ones who litter the public terrain with DOA prediction carcasses.....
The 2016 election Trump again reminded everyone that the vast majority of experts, pundits and journalists are not only terrible at short-term and long-term predictions, but also their failed prognostications usually, and directly, lead to public reactions that would not have occurred otherwise, such as the post-election anti-Trump riots.
As the New York Post cover page shown on the left confirms, the public was completely mislead by the mainstream media regarding Hillary Clinton's supposedly massive soon-to-be landslide election over the hapless Trump.
To compound the consensus expert election idiocy of 2016, many of the same "experts" then predicted that economic disaster would immediately follow this "unexpected" election of Trump. Here are the infamous Chuck Todd of NBC and Paul Krugman of the New York Times providing post-Trump election predictions that were completely without merit - literally, pure mainstream B.S. speculation posing as truth.
Now please note the 5-year Dow Jones Industrial chart depicted above on the right, as of Friday, November 12. Because investors were pleased that Hillary Clinton lost, the market set new records over the 3 days immediately after the election. The Trump unexpected coattails obviously extended beyond just the large GOP gains across the nation from the November 8 election.
Finally, because the experts and the media significantly misinformed the public constantly with Hillary-biased polls, combined with just plain ludicrous Trump fear-mongering, society's most gullible and misinformed Facebook generation went on a rampage with destructive and violent riots.
The moral of this story? The consensus experts, in almost every field, have an extremely high probability of being wrong, especially the ones pushing biased, agenda-driven doomsday scenarios and outcomes; and, the conclusion is indisputable: they should not be trusted at all by the public.
The consensus alarmist-scientist community has again been discomforted with new empirical evidence that confirms the findings of past research done by scientists skeptical of human-caused catastrophic global warming.
The new study, officially published in a publication from the Proceedings of the National Academy of Sciences, shows:
"....that water conserved by plants under high CO2 conditions compensates for much of the effect of warmer temperatures, retaining more water on land than predicted in commonly used drought assessments....the implications of plants needing less water with more CO2 in the environment changes assumptions of climate change impacts on agriculture, water resources, wildfire risk, and plant growth..."New satellite observations and improvements in our understanding hydrological cycle have led to significant advances in our ability to model changes in soil moisture," said Randerson. "Unfortunately, using proxy estimates of drought stress can give us misleading results because they ignore well-established principles from plant physiology."."
"Recent studies have estimated that more than 70 percent of our planet will experience more drought as carbon dioxide levels quadruple from pre-industrial levels over about the next 100 years. But when researchers account for changes in plants' water needs, this falls to 37 percent, with bigger differences concentrated in certain regions."
You read that right. The "consensus" scientists were forced to cut almost in half climate models' simulated drought impact on the world's plant life when the actual empirical evidence was properly analyzed.
Of course, despite the contrary findings of this study, the article reminds readers that hypothetical fearmongering from computer simulations is still acceptable, such as:
"Is this good news for climate change? Although the drying may be less extreme than in some current estimates, droughts will certainly increase, researchers said, and other aspects of climate change could have severe effects on vegetation."
"Up in the Arctic, things are getting slushy. But some polar bears are refusing to change their ways. Instead of compromising on where they spend their time, they’re clinging to the icy habitats they’ve always loved. As those habitats keep shrinking, though, the bears will eventually find things too crowded and uncomfortable to ignore."
Buuuuut....it would seem those stubborn bears just keep ignoring their human scientific betters whom keep predicting the demise of polar bear species.
“Polar bears are sticking to using the same type of habitat conditions even while sea ice disappears,” says lead author Ryan Wilson of the U.S. Fish and Wildlife Service. They still love regions with shallow water, a high but variable concentration of sea ice, and not much land-bound ice. He thinks that’s because—for now—they can still eat....So these polar bears seem to be doing fine without changing their habits."
Buuuuut....just wait until next season warns the Discover Magazine's species helicopter-parent nanny.
"As the iciest spots continue to shrink, more animals will have to either crowd into them or move onto solid land during the summer. They can’t stay stuck in their ways forever. These carefree polar bears will soon experience the same negative effects that their neighbors have, Wilson says: “It’s likely only a matter of time.”
The mountain of failed predictions and significant flip-flops seems to be never ending when it comes to climate change experts.
For years they predicted (i.e. carelessly speculated) that a warming climate would increase the incidence of the nasty dengue fever disease.
But now researchers are reporting that the incidence of the disease could actually be reduced with warming climate change.
“While climate change generally poses a major threat to humanity, it also may reduce the incidence of dengue in some areas,” said Dr Harley, an epidemiology researcher at the ANU Research School of Population Health. ... The findings are also relevant to other mosquito-borne viruses including Zika because the mosquitoes that carry dengue also transmit the Zika virus. ... “There is significant concern in countries on the margin of the tropical areas where dengue is mainly found, that with global warming dengue and other mosquito-borne viruses such as Zika will encroach and become common,” Dr Harley said. ... “Previous projections have suggested that climate change will increase transmission of mosquito-borne diseases globally. ... “Our work, using a mathematical model based on Queensland conditions, suggests that dengue transmission might decrease with greater warming.”
Naturally, this is good news that all global warming alarmists should embrace, with the exception of a single caveat regarding the study that should give pause. This latest flip-flop was based on a computer model, which is quite simply, nothing but simulated research using limited empirical evidence.
As has often been the case, official climate science is now agreeing with what skeptics identified several years ago: Antarctica is not warming.
The prestigious science consensus journal Nature has published a new peer-reviewed study that counters what that journal has been reporting about Antarctica for at least the last decade.
This should not come as a surprise to the observant.
The global warming doomsday scientists have relied on a compliant mainstream media to claim that their opinions represent the supposed 97% of settled science - an indisputable "consensus" that should not be debated. But, as in almost every scientific endeavor, the science is never, ever settled.
Yet the climate science orthodoxy continues to push the catastrophic scenario that Earth's major coastal and island regions will be submerged due to the melting of the polar ice sheets found in Antarctica. Unfortunately for the consensus alarmism, this new study indicates Antarctica's canary in the global warming fearmongering-fable has actually been cooling over the last 20 years, not warming (see chart).
"Natural variability was responsible both for the decades-long warming since the 1950s and more recent cooling, according to research published today in Nature. The research, led by John Turner from the British Antarctic Survey, said while the start of Antarctic Peninsula cooling in 1998 had coincided with the so-called “global warming hiatus”, the two were not connected."
And what do they say next, after being severely humiliated with the empirical evidence that skeptics rely on? Well.....the consensus doomsday scientists bounce right back with their orthodoxy beliefs, based on the always wrong climate model computer simulations.
"Scientists were quick to declare the results of the Turner et al paper, which covered 1 per cent of the Antarctic continent, did not negate a long-term warming because of man-made climate change...“Climate model projections forced with medium emission scenarios indicate the emergence of a large anthropogenic regional warming signal, comparable in magnitude to the late-20th-century peninsula warming, during the latter part of the current century,” the Turner research concluded."
Per a previous analysis of rising seas surrounding Pacific islands, the satellite measurements indicate that seas are rising but at a very meager rate. The current sea rise rate is significantly below what consensus climate science alarmists have predicted.
So, how do the doomsday claims that tropical islands are being lost to "rapidly" rising seas compare to reality?
Scientific peer-reviewed research can answer that question: The claims are bogus.
A new study examined the Jaluit Atoll of the Marshall Islands.
Back in 1958, Typhoon Ophelia passed by the atoll causing 14 deaths, plus resulting in the atoll shrinking in land area. Per the study:
"...the pair of New Zealand researchers set out to examine historical changes in 87 islands found within the Jaluit Atoll...over the period 1945-2010. During this time, the islands were subjected to ongoing sea level rise and the passage of a notable typhoon...which caused severe damage with its >100 knot winds and abnormal wave heights...caused a decrease in total island land area of approximately five percent, yet Ford and Kench write that “despite [this] significant typhoon-driven erosion and a relaxation period coincident with local sea-level rise, [the] islands have persisted and grown.” Between 1976 and 2006, for example, 73 out of the 87 islands increased in size, and by 2010, the total landmass of the islands had exceeded the pre-typhoon area by nearly 4 percent."
Simply stated, this study again confirms that doomsday prognostications based on climate model simulations have no relation to the actual Pacific island/atoll reality during periods of sea rise.
This article discusses the severe forest fire that is currently happening in the Fort McMurray area of Canada, which the article's author takes issue with those claiming the fire is due to climate change from human activities - i.e. human CO2 emissions, etc.
Claims that specific fires (and forest and wildfires overall) are due to human greenhouse gases have routinely been made since the 1988 testimony of NASA's top climate scientist, James Hansen, predicted that rapid and accelerating warming from GHG emissions would cause more severe and frequent weather events.
As a result of this Congressional testimony, the "consensus" climate experts then predicted that the "dangerous" human-caused warming would produce a significant trend increase of wildfires, especially in the northern hemisphere's boreal forests.
Although the globe has warmed since 1988 (not rapid, nor accelerating, see here and here), the trend for Canadian boreal forest fires has been the opposite of that predicted over the 27 years after the Hansen 1988 testimony.
The adjacent charts plots the number of Canadian forest fires and hectares burned. Clearly, the trends are declining, which suggests an inverse relationship with the level of atmospheric CO2 (ppm CO2 is the chart's right axis).
Despite those climate "experts" failed prognostications, the recent irrefutable empirical evidence indicates that the increased levels of atmospheric CO2 emissions are producing a greener and healthier biosphere, which actually may be more resistant to wildfires.
Additional forest fire articles of the past [tip: then use browser Cntrl-F function to do search on word 'forest' to find forest fire news articles on that page].
Note: Canadian forest fire statistics source; Excel used to plot annual fire statistics and linear trends.
"...report that "most trends exhibited no clear precipitation change," noting that "global changes in precipitation over the Earth's land mass excluding Antarctica relative to 1961-90 were estimated to be: -1.2±1.7, 2.6±2.5 and -5.4±8.1 percent per century for the periods 1850-2000, 1900-2000 and 1950-2000, respectively." ... "stations experiencing low, moderate and heavy annual precipitation did not show very different precipitation trends," ... "deserts/jungles are neither expanding nor shrinking due to changes in precipitation patterns." ... "reasonable to conclude that some caution is warranted about claiming that large changes to global precipitation have occurred during the last 150 years."
Simply put, the exaggerated climate change claims of major disruption to rainfall/snow patterns are just that, exaggerations sans any empirical evidence. The evidence-based science is clear: Over the last 150 years, precipitation trends remain within normal variability.
Doomsday climate models have been programmed to simulate greater ocean acidification levels as a result of increasing atmospheric CO2 from human emissions.
Simply stated, this predicted dangerous "acidification" is hypothesized to make the waters uninhabitable for most marine life.
And for this to become a reality, it means that a demonstrable and consistent decline in sea/ocean pH levels should be evident since the beginning of the industrial age.
In fact, as this study indicates, researchers are finding it exceedingly difficult to locate ocean/sea waters that exhibit a dangerous decline in pH values. In addition, as this chart shows (click on chart to enlarge), any slight change in pH from human sources is being swamped, multiple times, by natures own unpredictable wide variability.
"Expert" predictions, especially those associated with climate change, fail more often than not.
The climate change consensus has long been predicting that global warming will bring more flooding to river regions.
"...freshwater flooding is "the most impacting natural disaster in terms of number of people affected and economic damages," adding that "some studies in the literature (e.g. IPCC, 2013; Stern Review, 2007) seem to indicate that flood damages are expected to increase in the near future as a consequence of a global climate change," citing the additional studies of Hall et al. (2005) and de Moel et al. (2011)."
So, several scientists decided to actually analyse the available climate data for the Po River region of Italy to determine if the IPCC and other predictors had any merit.
As always, they found the predictions counter to reality:
"...analyses revealed there was a significant increase in residential growth in and around the Po river, particularly near levees and dykes, which increased the exposure of persons and property to flood risk over the period of study. However, meteorologically speaking, Domeneghetti et al. report flood events have not increased. "Consistent with previous analyses (see e.g. Montanari, 2012; Zanchettini et al., 2008)," they write, "our trend detection analysis, which we carried out on long historical series observed for the Po river, does not detect any evidence of a statistically significant change in the flood hazard along the Po river and supports the stationarity of the hydrological series during the period of interest (i.e., last five decades)."
Why does any sane person believe these knuckleheads?
Global warming alarmists, green activists, celebrities, and especially the mainstream press, collaborated in a loud chorus denouncing CO2 human emissions due to its supposed destructive nature on honeybee colonies.
With the onset of the widely publicized American 'colony collapse disorder', they were predicting that climate change from greenhouse gases would destroy the honeybees (and other bee species) and crop agriculture - meaning a massive starvation for mankind.
Something had to be done about global warming and this potential extinction. Climate change had to be dealt with swiftly. Do it for the children honeybees!!!
So, Obama proposed the typical tardy government response of more bureaucrats, taxpayer monies for scientists, and evidence-free untested policies, which will likely accomplish zilch.
In the meantime, the bee problem has been solved, like usual, via free markets, capitalism and individualism, not by govt diktat. Read the whole story here.
And not to be forgotten, like polar bears, another species predicted to go extinct a long time ago, bee colonies just reached a record high in the last 20 years at a time of the world's "hottest" temperatures evah and highest atmospheric CO2 levels.
Even with the strong surge in global temperatures from the current El Niño and from the surge of 2015 global warming exaggeration and fabrication (here, here and here), there remains the strange case of establishment climate science models failing to meet expected outcomes.
Case in point. This chart replicates the famous climate model output presented to Congress and the world in 1988 by James Hansen, the then chief climatologist of the NASA/GISS climate research unit. (Here is an image of the original chart.)
The climate model predicted annual temperature changes would follow the bright green curve if greenhouse gases (GHGs) were not curtailed. GHGs include: CO2, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride - the latter 3 are known as fluorinated greenhouse gases.
The orange curve represents the predicted annual temperature changes if the GHG growth rate were reduced over time.
The chart's cyan (aqua) curve datapoints are the predicted annual temperature changes if GHGs were curtailed by governmental polices and regulations so that year 2000 and beyond had a net growth rate equal to zero.
From the Hansen 1998 testimony, there is this statement:
"We have considered cases ranging from business as usual [BAU], which is scenario A, to draconian emission cuts, scenario C, which would totally eliminate net trace gas growth by year 2000."
From the 1988 Hansen peer-reviewed article that supports his testimony, there is this statement:
"We define three trace gas scenarios to provide an indication of how the predicted climate trend depends upon trace gas growth rates. Scenario 'A' [chart's green curve] 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' [chart's orange curve] 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' [chart's cyan curve] drastically reduces trace gas growth between 1990 and 2000 such that the greenhouse climate forcing ceases to increase after 2000."
So.....since NASA's top climate expert's testimony, what has happened with the GHG growth and growth rates?
From a recent U.S. EPA report on non-CO2 greenhouse gases, there is the following:
"Global non-CO2 emissions are projected to increase significantly between 2005 and 2030 unless further actions are taken to reduce emissions...total emissions of non-CO2 greenhouse gases have nonetheless increased."
From the latest IPCC AR5 climate report, we know the following about GHGs (a synopsis here):
"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.".....
In addition, 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.
Regarding fossil fuel CO2 emissions, specifically (CO2 data here): NASA and Hansen's 'BAU' Scenario A was proposed at a time when CO2 emissions were growing: since 1972, the 15 years ending 1987 the world emitted 285 billion tonnes of CO2. This represents a CO2 average growth rate of 2.2% per year for those 15 years prior to Hansen's 1988 testimony.
In contrast, for the 15 years ending 2014, the world has emitted a total of 467 billion tonnes - that is growth some 1.6 times greater than Hansen's 'BAU'. This represents a CO2 average growth rate of 2.9% per year for the period since 1999.
Without any doubt, both empirically and objectively, NASA's Hansen's projected GHG emissions for 'Scenario A' has easily been exceeded since his testimony in 1988. To state otherwise is a falsehood, categorically.
Now, back to the above chart.
For the year 2015, NASA's model predictions had temperature change for all 3 scenarios declining. Of course, we now know the exact opposite took place with the sharp increase in 2015 global temps.
It is important to note that since the 1988 testimony, the NASA climate predictions have very rarely been correct regarding annual temperature changes. (NASA is not an exception, though - all climate computer models and experts suffer the same level of failure.)
For what it's worth, the chart also shows the 2016 predictions: there is continuing decline for Scenarios B & C, but a sharp spike up for Scenario A to a record calendar year anomaly level.
While global warming alarmists are celebrating 2015 as the "warmest" year ever, the climate model failures clearly point to the absurdity of focusing on peak or trough moments as indicators of informed expertise. Peaks happen and troughs happen, in weather and climate, but pointing to either as scientific proof of computer simulations is not science.
Taking that to heart, the accompanying chart has 3-year average plots of highly adjusted observed temperatures from the NASA and UK climate agencies - the 3-year averages remove the focus from peaks/troughs.
As can be seen, 3-year averages of the GISS and HC4 datasets depict the last 3-year average increase due to the El Niño conditions, and those questionable man-made factors.
Be that as it may, the GISS and HC4 averages still remain closer to the realm of NASA's Scenario C range. As a reminder, the Scenario C predictions are a result of net zero GHG emissions simulated to have started in year 2000, which is yet another galaxy away from reality.
In conclusion, some relevant takeaways on climate models:
1. At this point, now close to 3 decades after NASA's testimony, one can safely surmise that expert climate models can't predict squat. The climate is a chaotic complex that defies even the most sophisticated and powerful forecasting tools.
2. GHG emissions have far surpassed the 1988 "world-will-soon-end" BAU construct - a construct that many alarmists still believe. Yet the predicted positive feedback from BAU has not occurred and thus runaway global warming is, without question, AWOL.
3. The climate models are still absolutely unable to discern either the amount or rate of global warming/cooling that is due to natural forces. The models were designed to purposefully rely on greenhouse gas forcings as their major causal factor, while diminishing natural climate impacts. It's no wonder that climate models remain on a fail path.
4. Based on the model outputs from 1960 to the present, policymakers and the public would be better served by rejecting the alarmist scenarios A and B; instead, moving forward, base all adaption and mitigation policies on Scenario 'C', which would likely produce better outcomes with superior allocation of scarce resources.
The climate models definitely have their important place in the climate researcher's toolbox. They are best suited to advance science's better understanding of our world, but their climate predictions, forecasts and prognostications should never be relied on - they are unreliable and inaccurate.
Update h/t: Video of climate scientist making the same point about climate model failure before a congressional committee on Feb 2, 2016:
The lower troposphere represents that layer of the atmosphere which is predicted to first experience the positive feedback of accelerated warming due to human greenhouse gases.
Recently, NOAA and NASA held a global warming presentation, which included various charts, and an unexpected admission that the atmosphere was not as warm as previous El Niño years.
An essential general review of the presentation can be found here.
The troposphere's lack of achieving the "warmest" year label was confirmed by the NOAA/NASA analysis of the relevant balloon and satellite datasets. And the adjacent chart is a combination from the NOAA/NASA presentation, with one chart being superimposed atop the other.
Other than a normal atmospheric response to the latest large El Niño temperature surge, the chart documents the continued lack of dangerous positive feedback warming.
As the state-of-the-art satellite technology shows (see chart), significant global warming since the early 2000’s has been nonexistent.
There has definitely been an extended ‘pause’ (aka the ‘Hiatus’ in science journals). The pause has generated some 60+ scientific explanations regarding its existence and persistence.
This has become a real problem for many proponents of dangerous global warming, which has recently pushed them into a stance of actually denying the 'pause'.
Empirically, since November 2000 the lower atmosphere temperature trend has actually been negative at a minus 0.12ºC per century trend. (The chart’s green curve is a 36-month average, which makes the pause even clearer to the casual observer.)
The chart also includes r-squared calculations, besides linear trends, that indicate a fairly weak 30-year relationship between CO2 and temperatures, which appears to have become a zero relationship over the last 15 years.
In review, the AGW theory is based on a CO2-induced warming of the lower atmosphere, at a rapid and accelerating warming rate - this being a result of the theory's speculative positive feedback loop.
As can be seen, the satellite empirical evidence after 30+ years does not readily support the climate-alarmist AGW theory, nor the doomsday predictions of global warming hell.
Although the satellites are considered the gold-standard for measuring and observing sea levels, hurricanes/typhoons, ozone holes, sea ice, atmospheric CO2 distribution, polar ice sheet masses and etc., the same 24/7 technology used to measure temperatures across the entire habitable world is now being ignored (i.e., denied) due to the above inconvenient evidence.
The adjacent chart pretty much makes a turkey mockery of accelerating global warming fears. It's simply not flying happening.
While the climate science establishment continues its costly and misallocated efforts against "catastrophic" global warming, the empirical evidence indicates the worlds' elites are pursuing a laughably ludicrous Don Quixote quest against an imaginary climate-evil.
Like so many Thanksgivings of the past, those on the 'quest' have piously announced civilization's reaching its 'last chance' point of saving itself from climate doomsday. But all of these TurkeynadoSharknado-like prophecies that the end-is-near have proven to be pure anti-science fiction.
At some point, we can hope some sanity returns to the climate science anti-CO2 Quixote brotherhood of warriors. But in the meantime, what does the actual climate science say?
Well, this chart is just brutally frank: the fast growth of atmospheric CO2 levels (the black dots) have not exactly been the robust evil foe the elite establishment has fixated on.
As the chart depicts, the CO2 impact on either short (red curve) or long-term (pink curve) rapid global temperature acceleration appears to be non-existent versus the "consensus" predictions. And the blue-dash curve reveals the rather turkey-like impact on the 36-month average of absolute global temperatures.
Indeed, global temperatures have increased since 1950. But the scientific reality is that the chart confirms a steady global warming that has been taking place since the end of the Little Ice Age (late 1700s) - well before the influx of the giant CO2 emissions from the industrial/consumer era. The chart clearly shows a long history of frequent periods of rapidly increasing temperatures, then to be always followed by a significant deceleration.
Examine the chart's most recent period, from December 1996 through October 2015. The periods of both rapid temperature increases and decreases are evident, just as they existed since instrumental recording of temperatures first began.
The vast majority of climate analysis based on actual empirical evidence show similar results, whether in a global or regional context.
Terrified by global warming doomsday? Not so much anymore, it would seem.
Suffice it to say, Americans are no longer impressed by the claims of government and celebrity elites. Fully 97% now reject the unreal turkey-esque predictions of climate change disasters.
And the American public is not alone. The global masses join Americans in their low assessment of the elites' unscientific climate calamities.
As the public has learned, the empirical evidence supports neither the man-made climate change disaster narrative nor the CO2-reducing solutions proposed, which have been seriously debunked.
With all that said, foolish anti-science elites will continue to make preposterous claims and those exaggerated, attic-crazy predictions leading up to the soon to be Paris COP21 climate conference.
One last 'chance' - look at the chart, are you still terrified this Thanksgiving? How about that wacky college-aged, censorship-loving, millennial niece gnawing on that turkey wing next to you?
Note: Excel used to calculate the 3-year absolute temperature and CO2 level averages; also used to calculate the moving 36-month and 360-month per century acceleration/deceleration trends (Excel slope function) as depicted on chart; the absolute temps calculated using the HadCRUT4 month anomalies and NOAA's monthly global mean temperature estimates; and, the 3-year average beginning value for CO2 was offset to a zero starting place. Temperature sources used: here and here. CO2 sources used: here (March 1958-October 2015) and here (used annual historical levels for each month of the given year, from January 1850 to February 1958).
The climate change fear-mongering generated by government-related persons and agencies has recently reached peak levels, with claims that are a mixture of absurd and just plain silly when compared to the empirical scientific evidence.
Such claims include the meme that rising global CO2 has caused accelerating, rapid US warming; that droughts are destroying all of our food crops; that more frequent and stronger weather disasters from warmer temperatures are wreaking untold harm; that global warming will shorten/threaten US life spans; that ever expanding wildfires are consuming our forests; and etc., etc., etc.
(One indeed wonders why so many Americans can't wait to retire to the tropical and warmer climates that Hawaii, Florida, Arizona and S. California offer if warm temperatures are so harmful and deadly.)
There are even bizarre claims that bumblebees' tongues are shortening and pumpkin pies are at risk, both supposedly due to global warming.
With all that said, the U.S. has the best weather and climate measurement capabilities in the world, with observations from a wide geographical dispersion and a extensive range of micro-climates, be it tropical islands or Arctic tundra. The most extensive and complete empirical evidence comes from the continental U.S., which the vast majority of the American population resides.
Instead of believing the promoters of doomsday screams about every single impending weather event being the next civilization-busting disaster, or the journo/pundits' propensity to shout about the hottest hour, the hottest day, week, month, summer and/or hottest year stats (take your pick) ad nauseum, it might be best to reflect on what the American public has realized about long-term climate change doomsday from the empirical evidence - it's a very thin nothing-burger.
To the empirical evidence.
The adjacent chart depicts several long-term climate record trends of 10-year averages (US hurricane landfalls, forest fire acres, drought, precipitation, maximum and average temperatures). The chart also includes the following 10-year average trends: atmospheric CO2 levels; the U.S. corn yield; and, the U.S. life expectancy trend from decadal census information.
As can be seen, the CO2 growth trend has been truly remarkable, only exceeded by the exceptional trend for corn yields (by the way, other agricultural crops also possess exceptional yield trends). And the increasing life expectancy trend for Americans is none too shabby either.
In contrast, the charts reveal the truly unexceptional, unremarkable long-term trends for any climate/weather attribute previously predicted to worsen from the modern era's CO2-induced climate change.
These fitted curve trends have yawn-inducing characteristics, indicating CO2 from fossil fuel combustion is spectacularly not the powerful greenhouse gas emission that experts conjectured about.
Conclusion: Although short-term variation extremes in weather attributes and incidents can be large and at times awe-inspiring, they are not climate change. Long-term climate change since the Little Ice Age has been dominated by a very slow warming, which the chart's 'average' and 'maximum' temperature trends reveal. The long-term climate change across the continental U.S. as represented by the precipitation, hurricane landfall events and drought are much more difficult to discern from their respective fitted trends (objectively, they are rather climatically insignificant overall). Forest fire acres burned has had an uptick in recent years (for bureaucratic reasons) but is vastly below levels reached in the early 20th century. All in all, human CO2 combustion emissions are directly linked to the great agricultural prosperity and vastly improved well being of the American citizen over the past century, much to the chagrin of doomsday cultists - whether yesteryear's or today's.
In other words, the politicos and bureaucrats predictions of gloom, doom and disasters were wrong, significantly.
Notes: Excel used to produce chart's fitted 2nd order trends. Sources of datasets used for chart can be found by downloading this Excel spreadsheet from MS OneDrive. For the temperature, precipitation and drought (PHDI) curves, 9-month YTD through September measurements from NOAA were used. CO2 levels used for its trend curve represents the September ppm value for each year. Corn yields represent the 'commodity and market' year reported. Both corn and CO2 had beginning values set to '10' in order that they would fit on a '0' to '150' y-axis (did not affect linear trends of either). Hurricane US landfalls observations used represent a per year average from the given decade's count of events. Life expectancy data are U.S. decadal averages for female/male and all races.
As the site 'Not A Lot of People Know That' reports, extreme and severe rainfall (i.e. precipitation) trend has not increased in Holland, when viewed from a decadal perspective.
The adjacent chart depicts the distribution of the top 50 DeBilt, Holland rainfall events while atmospheric CO2 levels increased over the decades. (Go here to view maximum hourly precipitation incidents versus global cumulative CO2 emission tonnes since 1950.)
For the record, on any given hour during any given day, someplace in the world is likely to be experiencing an extreme weather event. But as this Holland dataset confirms, the actual empirical global and regional trends of a climatic shift of ever more severe weather events do not support the alarmists' predictions; the irrational fears of more frequent/larger weather disasters as a result of CO2 or global/regional "warming" is unjustified, per the scientific evidence.
And it is indisputable that hundreds of media outlets have extensively documentedover the past century that weather catastrophes have always been a normal climate occurrence, regardless of greenhouse gas emissions.
Note: 'C3' used monthly CO2 levels from NOAA and superimposed the CO2 curve on the above chart.
The climate doomsday-cult promoters at the Huffington Post and Climate Nexus did their usual thing, trying to convince the American public that Hurricane Joaquin was the result of global warming.
Of course, when the alarmists uttered these claims, they were based on the hurricane computer models that forecast Joaquin's path would strike the East Coast of the U.S. Fortunately for the coastal residents, the climate change doomsters were wrong, spectacularly.
Instead, as the adjacent chart clearly documents, those ocean waters have cooled since 1940, not warmed as predicted. Another case of 'those stubborn facts'.
In summary, the empirical evidence again confirms that climate simulations and computer models are very suspect regarding their capabilities at both short and long-term predictions/forecasts. Governing elites, bureaucrats and the public should absolutely not base any expensive policy-making decisions on these research tools.
Per NOAA, the U.S. warming pause (aka the 'Hiatus') has now achieved a 19-year stall (see adjacent chart). In fact, a slight cooling has been the trend over this period.
Remember the predicted global warming by experts? The same "experts" who predicted that hurricanes would become stronger and more frequent as a result of the global warming - which also did not happen.
As the empirical climate datasets reveal, the predicted global warming has amounted to about nil for close to two decades. And because of this, the global warming scientists recently resorted to exceptional fabrications of temperature datasets to produce "warming" that disappears the 'Pause'.
Ginning up climate change fears in anticipation of the Paris 2015 COP21 climate travesty show seems to be the driving force behind the most recent wholesale fake-warming production.
Back to the included chart. As depicted, the 19-year pause includes not only the continental U.S. (at -0.4°F per century cooling) but also the states of Virginia and Maryland, both at -0.5°F per century cooling.
Why depict those two state's temperature trends?
Because those states surround the metropolitan District of Columbia where federal bureaucrats, U.S. elected representatives and administration officials pontificate about the rapid and dangerous "global warming". These elites live and work in the D.C. micro-climate warming bubble that is a direct result of federal taxpayer asphalt, steel, concrete and airports with very hot jet exhausts, which in combination have produced a rapidly warming urban heat island (UHI).
The NOAA scientific empirical evidence is rather clear and undeniable. For most Americans, global warming is not an issue and is definitely not impacting their daily lives.
But for a minority of governing elites, who obviously created a hostile warming micro-climate for their work environment, it has made them incapable of distinguishing the climate forest from the micro-climate trees, so-to-speak. Or, put another way, they can't discern the difference between climate reality and climate fantasy.
Hmmm....maybe the best solution for saving the elites from their own, self-created hostile and climate change triggering environment is to disperse the federal government offices and personnel across rural locations throughout the U.S.
Note: The per century temperature trends for the continental U.S, Maryland, Virginia and D.C. were produced using NOAA's 12-month temperature periods ending in the month of August, through August 2015. Source of NOAA data used. NOAA images (a Zip file) of chart's calculated per century trends used.
Here's a chart that NOAA and other govt-funded global warming proponents are not about to advertise. Instead, rest assured, they will be cherry-picking the usual meme of hottest day or week or month or quarter and/or year to publicize.
But when longer periods are examined, those favored govt/media 'cherry-picks' start to look exceptionally lame in comparison.
For example, the NOAA web site produced this chart that allows analysis of average U.S. temperatures over 5-year periods (60-month periods). The chart starts in 1988 (5-years ending 1988) when NASA's chief global warming alarmist predicted (at a U.S. Senate hearing) that the U.S. would also suffer from the global warming trend with dire consequences.
As the chart reveals, the U.S. warmed thru June 1992; then cooled until end of June 1997; then significantly warmed thru June 2000; and has since experienced a cooling trend that stretches to June 30, 2015. Clarifying, from 2000-2015 covers a 16-year span, which indisputably shows a 'pause' in 5-year warming that NOAA correctly identifies as a cooling trend.
It's a cooling trend equaling 1.3°F per century. And not a single government sponsored climate expert, nor wildly expensive climate model, predicted such.
The Pope's climate doomsday encyclical has generated a lot of controversy; and has probably doomed him to be eventually nominated for the Catholic 'hall of shame' for fear mongering anti-science.
Of course, it's not completely the Pope's fault for his ignorance. The Pope's gatekeepers and advisers can take much of the credit for making sure he did not hear about the actual climate science empirical evidence.
One climate doomsday scenario (among many) that continues to have no basis in climate science reality is the infamous prediction that Gaia will soon have a Venus-like atmosphere and boiling oceans...because of humans fossil fuel use. You can rest assured that Pope Francis was made aware of the potentiality of this fringe calamity.
It's a calamity that has long been pushed by the world's leading climate science alarmists.
NASA's former top climate expert, James Hansen, has been in the past a principal proponent of this particular doomsday prophecy. And of course, he provided the dramatic testimony to Congress in the summer of 1988 that really initiated the fear mongering in the U.S. regarding catastrophic global warming and climate change disasters - like turning Earth into Venus.
Unfortunately for the Pope, James Hansen and other hysterical climate doomsday soothsayers, the real world empirical evidence clearly shows that the world's climate is self-correcting and not prone to those scary predicted tipping points and runaway disasters from growing atmospheric CO2 levels.
Case in point: The Tropics (20S to 20N latitudes) - A Venus Doomsday?
The above chart plot reveals a tropical climate, as measured by satellites, experiencing a very slight cooling trend (blue curve) over the last 20 years. In contrast, the IPCC's latest climate model (CMIP5/RCP4.5) curve (green line) predicted a significant warming trend during that same 20-year period.
Going back even further, the red chart plot depicts an 83-month period of exceptional warming right after the Hansen testimony of 1988. In contrast, the IPCC climate models predicted a significant cooling trend for the Tropics for those 83 months - an abysmal failure, represented by a 7 degree trend difference between reality and prediction.
Needless to say, although we will, both the consensus climate experts and climate models have been spectacularly wrong in their doomsday projections for the Tropics, which means that human CO2 causing Venus-like conditions for Gaia has no basis in climate science reality.
It's unfortunate that this pope fell victim to his own gullibility and the anti-science machinations of his court jesters advisers. But there is good news for the Catholic masses: you can now also comfortably ignore this encyclical since it was produced from the irrational passion of fear versus the known rational, empirical climate science.
Political expedience, and a craving to please, truly corrupts scientists and the science they produce...in an era when science fraud is on an exponential rise, one would think that climate agencies would be more careful with their scientific integrity...especially in a year of a major climate conference...did NOAA just provide a new Climategate-effort of science deception?...similar to what sunk Copenhagen2009?.....

The past several days has seen much written about the new revision of the NOAA global temperature dataset - a revision that supposedly eliminates the global warming 'pause' or if you prefer, the 'hiatus'.
The revision has received withering scrutiny, with multiple significant criticisms being leveled. Clearly, as the critics point out, this revision is not based on any known physical science principles, nor on any new empirical evidence, but instead on a political agenda that demands "scientists" find more global warming, pronto, for the Paris 2015 climate elite bureaucrats hookup extravaganza.
By utilizing questionable adjustments based on even more questionable assumptions, NOAA managed to produce an entirely fabricated increase in the global warming trend from 1998 to 2012. Theirs is not a real global warming event, it is essentially nothing more than statistical flimflam.
Per the critics, several key failings include:
The complete ignoring of the world's best climate measurement technologies - satellites and the Argo ocean-float array system - likely ignored because both technologies show little if any warming in their respective realms.
The authors provided a statistical significance level of a remarkably lame .10 - so lame it pretty much alone indicates this study's claims have the lasting robustness of toilet paper after flushing.
This study significantly lowered sea surface temperatures, specifically from 1998-2000. This lowering had the immediate impact of making the temperature rise from 2000-2012 appear much larger than it really was.
Study used Arctic land temperatures to manufacture rising Arctic sea temperatures - conveniently ignoring that regional sea temperatures are almost always zero (0°C) since sea ice stretches across the area for a majority of a given year.
In a rather bizarre manner that non-biased scientists would not employ, this study massively adjusted up the ocean buoy temperature measurements in order to match the ship records of engine water intake temperature; yet the buoys were designed to measure surrounding sea temperatures, and the engine intakes were not. Scientists familiar with this issue agree that the ship engine enhanced temperature measurements should have been adjusted down instead.
Despite all the ludicrous adjustment machinations this newest NOAA revision relies on, the per century global warming trend fabricated (for the 1998 to 2012 period) remains well below even the IPCC's average climate model projections.
Relevant to that last point, is the above chart. It's a comparison of warming trends during the 15-year periods ending 2012 (see blue rectangles) and 1997 (see red circles).
Using climate agency temperature anomalies that were reported as of the end of 2012, one can clearly see the dramatic drop in global warming rates from the earlier 1983-1997 period versus the period ending 2012.
Did it still warm from 1998 to 2012?
Yes, it did. But it was at a fraction of the warming trend of the previous 15 years - a definitive slowdown versus the prior warming trend.
And as the chart reveals, the CMIP models (the RCP 4.5 scenarios) expected significantly more warming than observed during 1998-2012 period. Objectively, the models predicted an accelerating warming rate, which actually failed to happen, as the empirical evidence proves.
Because of this decline ('pause'?) in global warming trends, NOAA felt compelled to simply fabricate more warming in a rather feeble attempt to make global warming seem more of a existential threat that might even scare an anti-capitalism Pope into embarrassing fear-mongering.
Unfortunately for the "scientists" at NOAA, despite all their really lame statistical shenanigans, the revised NOAA temperature trend for the 15-year period ending 2012 is still a quite tepid 0.9°C per century - indeed, the descriptor 'lukewarm' readily comes to mind.
Article: Since 1980s, the Australian region has experienced a tropical cyclone trend that would send shivers down the spine of any global warming alarmist. Just another confirmation to be added to the pile of empirical evidence that challenges catastrophic global warming claims.
That catastrophic anthropogenic "global warming" from CO2 just does not want to play by the IPCC agenda rules ... the predicted "for sure" global sea ice melting has taken a hiatus since the turn of the century ... this very inconvenient pause (stall?) will soon reach a full 15 years ... not a single IPCC climate model or "expert" predicted this outcome ... and just as a reminder, they can't predict 'squat'.....
(click on chart to enlarge)
It's another day and another stubborn climate fact: global sea ice is not melting as expected by the experts.
This chart, per the U.S. government's funded NSIDC's dataset, clearly documents the global melting pause.
Unexpectedly for the IPCC and associates, the trend is flat, despite the greatest growth in human CO2 emissions ever recorded.
At this point, it would be safe to say that the empirical evidence confirms that past hysterical projections of a global sea ice meltdown by global warming alarmists were without true scientific merit, due to being based on an untested and weak hypothesis that humans would cause catastrophic climate change.
As always, the UN and its elite climate "science" agency are abysmally wrong ... once again ... failed predictions seem to be the preferred coin of the IPCC realm ... begs the question: will the IPCC even achieve 10% of their catastrophic global warming predictions being correct over the next few decades? ... highly unlikely, due to its political agenda and the absurd reliance on climate models that simply don't work as advertised.....

Per this article, the catastrophic sea rise predictions of CAGW proponents are found to be without any merit.
The new study examined 118 years of empirical evidence and discovered that small Pacific islands are not disappearing under the waves of a rising ocean. Instead, the tiny atoll islands are actually growing larger.
Winter can be sooo cruel...especially for scientists who have long immersed themselves in the pile of manure that CO2 CAGW hysteria represents...good news, though!...NASA and James Hansen have a fallback position...namely, the previous climate hysteria predictions they and the press were pushing on Congress and the public.....

This updated NOAA U.S. temperature map is a stark reminder of the incredibly cold climate that northern and eastern areas of the US have recently experienced. The bitter cold, in particular, impacted those regions east of the Mississippi River, with states butting up against Canada taking the brunt.
It's also a reminder of those predictions by NASA experts and computer models, as promulgated during 1988 congressional testimony, that accelerated global warming would significantly impact the U.S., with many "experts" then claiming our future was one of warmer winters and no snow.
More to that point is the adjacent chart of US Nov/Dec/Jan temperatures (28 years) and trends since that 1988 testimony. It represents the following 8 states: Wisconsin, Michigan, Ohio, Pennsylvania, New York, Vermont, New Hampshire and Maine (all these states are east of the Mississippi and share a border with Canada).
To summarize the chart essentials:
1. Winter temperatures (Nov/Dec/Jan) exhibit a strong variability (the blue columns). Clearly, increasing atmospheric CO2 levels during this period has not caused ever-warmer winters.
2. Many of the winters are below the 1988 average of 27.58°F, including the winters of 2014 and 2015. (see blue dashed line)
3. Despite the very warm winter of 2002, the overall warming trend (orange curves) of winter temperatures has collapsed to a cooling trend of -5.7°F. There is no escaping the obvious NOAA empirical evidence that greenhouse gases are not producing the predicted accelerated warming.
4. The 10-year average winter temperature (the green curve) peaked in 2007 from a low experienced in 1989. Without any doubt, those few very exceptional warm winters (5 of the 28 winter datapoints) have definitely moved the average up. With that said, since 2007 it has declined slightly.
Is the U.S. just a rare anomaly where a cooling winter trend, not warming, is happening? Unfortunately, for the public and CAGW-scientists, regions with cooling trends are becoming more common.
Additional current empirical evidence that CO2 does not cause dangerous "warming" winters:
Note: Source of dataset for 8-state winter temperature chart produced by Excel. Using Excel calculated the 8-state winter months average; the 10-year trends and averages that begin with year 1988 on the chart used U.S. winter (Nov/Jan/Dec) temperature data starting with November 1979.The 1988 blue-diamond column on chart represents year of James Hansen global warming testimony.
The East Coast elites, aging yuppies and metrosexual deadenders who bitterly cling to the CO2-caused "global warming" religion are having a tough time...over the last 20 years, winters in the Northeast region of the U.S. have become more harsh and severe...that's opposite of their climate-doomsday cult leaders' predictions...instead of getting climate news from the likes of Al Gore and Brian Williams, Northeast denizens of elite enclaves might want to finally introduce themselves to what is called empirical evidence.....

As the U.S. East Coast continues to dig out from another major blizzard, it is a reminder that natural climate forces and patterns have eviscerated the predictions made by by government climate "experts." Their predictions of warmer winters and less snow have not only been incorrect, they have been flat-out spectacularly wrong.
While ignorance is bliss for many, it is still is no excuse for the elites of politics and media to continue to spread falsehoods about CO2 causing warming winters.
As the above NOAA graphs clearly document, the strong cooling trend for the winter months of December (19 years), January (21 years) and February (20 years) across the U.S. northeast is indisputable.
Let's be clear about this: there is no identifiable group of climate-doomsday experts within government-funded circles who predicted twenty years ago that CO2 would cause this cooling trend outcome.
And precipitation trends over the same time periods in the Northeast? Well, depending on the month, take your pick, up or down. For any given winter month, one year of cold temperatures could produce a wet or a dry month.
It would appear that winter weather is not that predictable from year to year; and obviously, nor are climate conditions some 10, 20 30 or 50 years into the future.
Those who have relied on the CO2-induced AGW climate hypothesis have continuously been proven wrong. Yet, the CO2 cult faithful still hold climate doomsday predictions as gospel, regardless of the empirical science.
The updated NASA/Hansen climate model chart with the latest GISS and HadCRUT4 observations remains a testament to abject climate model failure by the anointed "experts"...chart includes updated GHG growth trends from IPCC AR5...not surprisingly, climate reality is very unkind to the CO2-centric computer simulation predictions...one could fairly surmise from the actual performance of models and experts that they can't predict squat...just say'n.....
(click on chart to enlarge)
No matter how many years go by, the trend towards ever worse climate model predictions continues.
Case in point: The NASA/Hansen climate model that was used by climate experts to convince the politicians, the media and pubic that the world was at severe risk for massive global warming if greenhouse gas (GHG) emissions were not drastically cut.
This model's predictions came to the forefront when NASA's James Hansen provided testimony to the U.S. Senate in 1988. As it was discovered much later, the Hansen testimony was stage-crafted for maximum fear-mongering impact, which should have been the first clue that there was a credibility issue regarding the climate model.
Before diving into the details, a short glance at the accompanying chart provides the critical policymaker insight:
Essentially, the NASA model predicted temperatures would follow the bright green curve if GHGs were not curtailed. The cyan (aqua) curve datapoints are the predicted temperatures if GHGs were curtailed. Greenhouse gases have continued their accelerated growth, yet the observed temperatures (the green and pink circles) closely match the cyan curve. Simply, the model's predictions have been spectacularly wrong, worsening by the year.
The following provides more details:
The newly published 2014 IPCC AR5 summary report bemoaned the recent significant growth increase of GHGs. The IPCC established the per year growth, prior to 2000, to be at a 1.3% rate. The IPCC AR5 reports that GHG growth has now jumped to 2.2% per year through 2010 (see more details here).
[Editor: Speaking to CO2 emissions more specifically, using the 1999 year-end global CO2 emission level as the base year, CO2 emissions have grown at an average 3.0% per year pace as of the end of 2013. That's 14 years of exceptional growth. In contrast, the 14 years of CO2 growth prior to 1988 is only 1.8% per year (read below as to why prior to 1988).]
To say that GHGs have exceeded the 'business-as-usual" (BAU) scenario would be an understatement - according to the IPCC AR5, a 70% increase has taken place, on a per year basis.
Of course, the BAU scenario was made famous by during that 1988 U.S. Senate hearing.
Per Hansen: "We have considered cases ranging from business as usual, which is scenario A, to draconian emission cuts, scenario C, which would totally eliminate net trace gas growth by year 2000."
In a peer-reviewed article supporting his testimony, he stated that the 1970s and 1980s had an approximate annual growth average of 1.5% (prior to 1988). This was the paper's BAU 'Scenario A' that he spoke of in his testimony. In his written Senate statement, he included an appendix that verifies the ~1.5% BAU estimate for GHGs, plus a chart that depicted the scenarios A, B and C.
That chart is replicated above, with Scenario 'A' being the green curve; the 'B' scenario is the orange curve; and the cyan curve is the 'C' scenario, which represents the 'draconian' emission cuts Hansen states are required to minimize potential global warming.
As stated previously, the IPCC has confirmed the rapid, continuing growth of GHGs since the end of 1999, which per the NASA climate model, should have produced global warming equal to the bright green curve on the chart.
Instead, climate reality and natural climatic forces intruded - real world temperatures since 1988 resemble the cyan temperature curve of "draconian" emission cuts that Hansen's testimony implied would necessarily make global warming safe by end of 2014.
As it turns out, some 25+ years later at the end of 2014, we currently have achieved that implied 'safe' global warming that the climate modelers and experts predicted would not happen unless there were forced gigantic emission cuts.
Objectively, the empirical evidence leads to a couple of reality-based, undeniable and incontrovertible conclusions: policymakers should not rely on the unreliable climate models - they're egregiously wrong and not getting much better; and, climate experts truly do not understand the natural forces dominating the climate system.
Notes: This updated NASA/Hansen chart now uses the current HC4 and GISS V3 datasets, as of 12/31/14. Instead of plotting individual year datapoints for observed temperatures, plotted 3-year (36-month averages ending in December): this reflects an expectation that models can't predict accurately every annual period, but over longer 3-year periods the model and observation trends should better match. Starting in 1960, both GISS and HC4 3-year averages were offset to start at zero (0.0°C) anomaly. To reduce the clutter on chart, only 'even' year observed 3-year temperature datapoints were plotted. The small insert chart is data from IPCC AR5 summary report. The green, orange and cyan Hansen model plots came from this climate-doomsday site.
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.....
(click on graph to enlarge)
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.

Climate-doomsday cult predictions of CO2-induced extreme climate change have been a common, easy refrain of politicos seeking donations from special interest groups...yet, the empirical evidence provided by NOAA and other climate agencies is simply overwhelming...those much anticipated increases of severe weather events from greenhouse gases are just not happening, including U.S. tornadoes.....
(click on chart to enlarge)
Tornadoes. They're dangerous and they're unsympathetic killers.
These extreme weather events are officially categorized in severity from 'EF0' to 'EF5' - with the higher number being the rarest of the killer tornadoes.
As this chart reveals, the good news for the U.S. is that the categories of severe tornadoes (E2-E5) are on the decline. The declining trends, since the 1950's period of lower atmospheric CO2 levels, are indisputable.
Based on a casual observation, one might conclude that increasing CO2 levels and global warming have curtailed these frightening weather phenomenon. Good!
Ahhh...those stubborn climate facts provided by NOAA are just sooo inconvenient at times, no?
Note: During the 2011 tornado season, there was a strong uptick but since then the severity T-counts have subsided, confirming the longer-term trend. 1950-2013 tornado dataset here. NOAA has not yet published official the 2014 severe tornado counts. Severe tornado counts for 2014 were confimed here, here, here, here, here and here. Above plots and trends produced using Excel.
NOAA and NCDC have updated many of their weather/climate trend reports for end of 2014...as observed in the recent past, severe weather trends have not seen the "expert" predicted increase from CO2, other greenhouse gases and, of course, global warming...the climate-doomsday cult talk from political-persons, mainstream reporters/pundits and on-the-dole bureaucrats remains without any empirical merit.....
(click on chart to enlarge)
One means to view the lack of climate extremes is to examine an interesting dataset that NOAA/NCDC maintains - the monthly % of U.S. that is either very wet and/or very dry. It has recently been updated through 2014.
As can be seen from this chart, very wet and very dry U.S. conditions fluctuate dramatically. Yet, some 45 years after 1970, the 5-year averages by the end of 2014 are close to the values decades before.
The huge increase of atmospheric CO2 levels from human emissions over this time obviously has had no impact (e.g. correlations of either climate condition with CO2 doesn't even reach the ±0.03 yawn mark).
This NOAA dataset extends all the way back to 1895; and the end result is its being, on average, within the same narrow range over the last century.
Despite the proclamations by those politicians and elites who are readily influenced by moneyed special interests, there is yet to be any empirical scientific evidence that CO2 is a causal agent producing extreme climate change or severe weather events.
The world's climate "experts" long ago predicted extreme, rapid and dangerous warming for land masses occupying the higher latitudes...extreme warming for those subarctic and polar regions... Canada's climate must not have gotten the NASA memo.....
(click on table to enlarge)
NASA's climate experts are on record for predicting all sorts of climate catastrophes, including extreme warming of the world's 'higher' latitudes (the world's polar/subpolar regions).
Certainly for Antarctica, that prediction was simply a spectacular failure.
Now comes information that NASA's "hottest-ever" year/decade has not produced a single hot temperature record in Canada since 1961. With Canadian lands mostly occupying the higher latitudes ('subarctic' starts at 50N), this is remarkable empirical evidence that the predicted extreme climate change is not so extreme.
The adjacent table of Canadian hottest temperatures recorded documents that this massive area near the top of the world has not experienced the natural hotter climate that it once had during the 1930s and 40s.
The table also includes the last 15 years of Canadian warmest temperatures - not a single year coming close to previous records with the exception of year 2007.
CAGW proponents have a long-held belief that CO2 emissions and other greenhouse gases are rapidly warming the Antarctica continent along with the surrounding oceans...further, this out-of-control warming is quickly melting sea ice and the South Pole's massive ice sheets...turns out, it's a case of unrepentant denial of climate reality.....
(click on graph to enlarge)
Way back in 1988, a NASA climate expert gave testimony that the 'high latitudes' (i.e. polar) would experience greater warming due to growth of human greenhouse gases (GHGs), including CO2 emissions.
This prediction was seized upon by global warming advocates as "proof" that the South Pole's unprecedented warming would melt sea ice and cause melting ice sheets to collapse, raising ocean levels and thus submerging worldwide coastal areas.
Indeed, there is strong evidence that GHGs have risen considerably - even to a greater extent then the feared 'business-as-usual' scenario NASA/GISS experts promulgated.
Yet the newest empirical research completely counters the fears and beliefs of the CAGW crowd: over the satellite era, some 30+ years, Antarctica's ice sheets have slightly grown and the South Pole's sea ice extent is at record levels.
Then there is the proverbial elephant in the CAGW room: the Antarctica region is not warming, per the advanced satellite technology of NASA. Those stubborn facts are indisputable and unequivocal.
Yet, denial of this empirical scientific evidence remains widespread, preventing a rational debate about the real implications of the ongoing natural climate change.
[Update: A reader inquired as to the correlation between the temperature anonmalies and monthly CO2 (ppm) levels - it was 0.015. This figure suggests that seeking a link between CO2 and South Pole temps may be barking up the wrong tree, so to speak.]
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.

Remember when those NASA/NOAA climate experts predicted a rapidly dangerous warming for Americans?...based on the last 15 years, coastal urban elites just might consider moving to fly-over-country where cooling rules...their dedication to the absurd beloved precautionary principle certainly seems to dictate this simple precaution.....
As this NOAA/NCDC regional climate map reveals, the vast majority of the continental U.S. has not warmed for the last 15 calendar years.
Specifically, for the entire continental U.S, the 2000-2014 calendar span has seen a -2.7°F/century cooling while 7 of the 9 climate regions had cooling or temperature trend stability.
However, there are two regions of the U.S. that have experienced warming trends - on the east and west coasts.
It is highly doubtful that global CO2 emissions would only affect these two geographic areas and not "global warm" the rest of the country. Objectively, it's more likely that there are other micro-regional climatic and human factors involved for the specific coastal state warmings.
Since 1997, the continental U.S. suffers from a significant cooling trend, per NOAA...will CO2 emissions be able to save us from the looming next ice age?.....

As NOAA is now reporting, the U.S. is in the midst of an extended cooling trend - 18 years and counting.
According to the IPCC and 97% of all "expert" climate scientists, the explosive growth of CO2 emissions and other trace greenhouse gases should have caused accelerated warming, not cooling.
The cooling trend is at a -1.9°F per century for the last 18 years. And since the end of the 20th century, the cooling has accelerated to a -3.5°F trend/century (years 1999 thru 2014) . That would be a doubling-down on 'Ooops', so to speak.
2014 the "hottest" U.S. year ever meme? Nope, didn't happen. In fact, this past year turned out to be the 5th coolest during that 18-year period.
Here is an interesting task for any CO2-centric global warming/climate change alarmist:
Identify from the 1980-1990's a single NOAA/NCDC/NASA climate expert on the taxpayer dole, at that time, who publicly stated this was a likely result. And the billion-dollar+ government-funded climate model(s) that actually predicted this very inconvenient climate cooling outcome.
In front of cameras, a hot and sweaty James Hansen of NASA gave his famous global warmingEOTWAWKItestimony...lucky for the rest of us, this climate "expert" was spectacularly wrong.....
(click on graph to enlarge)
During a hot June 1988, NASA's James Hansen provided a provocative, stage-crafted testimony to the U.S. Senate.
His message? The world of 1988 was the hottest ever, since the 1800's, and it was due to humans' fossil fuel CO2 emissions; and more importantly, global warming would continue its upward path, rapidly getting worse and then becoming a threat to civilization unless CO2 emissions were constrained - i.e. reduced significantly.
Why his EOTWAWKI message? Because the modern crystal ball - his computer climate model simulations - told him so.
This chart plots the global temperatures using the most advanced, costly climate measuring technology provided to the scientific community by the American taxpayer. The empirical measurement evidence over the last 26.5 years since his testimony tells a different story than what Hansen predicted.
What do the satellites say? This state-of-the-art measurement technology ignores crystal ball predictions by experts and instead objectively reports that over the last 18 years "global warming" has been a non-issue. Despite record amounts of greenhouse gases being spewed into the atmosphere, global warming has not accelerated and has not become a threat.
How bad were Hansen's computer model predictions?
In his testimony, he spoke of causation between global warming and CO2 emissions - the more CO2 released, the greater and faster temps will rise. Yet, over the last 18 years, the world has experienced a very tiny cooling trend, per the satellites. And the "causation"? Well...ahem...calculating the statistical correlation between global temperatures and CO2 ppm levels over the last 18 years produces a negative correlation, with a r2 of 0.0004.
Dr. Hansen does deserve credit however. The first 8.5 years after his testimony, satellites measured the global warming trend at a +1.22°C increase by 2100AD. And the r2 for temperatures and CO2 was 0.21 (note to climatologists of alarmism persuasion: one does not want to make predictions of catastrophe with this statistical attribute level).
The conclusion? The end of the global warming 'EOTWAWKI' as we know it, no? Damn those stubborn facts!
In the previous 'C3' article, we looked at U.S. temperatures since 1988 when a NASA climate expert in U.S. senate testimony made predictions of near-future catastrophic climate change and, of course, dangerous global warming.
As the article documented, temperatures in the U.S. have essentially been at a standstill over the last 10+ years, and catastrophic climate change (with its millions of IPCC predicted "climate refugees") is nowhere to be found.
The end result is the undeniable evidence that America's climate records are non-consistent with the well publicized climate expert climate predictions, and also with the billion dollar super-computer models that experts and mainstream journalists claim to be climate-omniscient.
It begs the question: Is the non-consistent climate reality in the U.S. also found in other parts of the world?
Turns out that the UK climate records, as represented by the Central England Temperature (CET) dataset, reveals the same expert abject failures and non-consistency with model simulations. "Rapid" and "dangerous" accelerated warming hasn't taken place there either.
Unlike the continental U.S., with its abundance of micro and regional climates, the small island area of Great Britain affords less climate variety yet produces similar warming/cooling trends over the recent past.
Like the U.S. dataset plots, the CET dataset is for the full 26 years (312 months through Nov. 2014) since late 1988 when both UK and U.S. catastrophic climate proponents initiated their public fearmongering campaign - the year of James Hansen's scare-testimony.
The adjacent UK chart depicts both the plots for 60-month temperature and CO2 averages. Clearly, the predicted rise in temperature due to higher CO2 levels has not happened - this is not consistent with any climate model simulation that the experts tout.
With a r2 of 0.00 between monthly CO2 and temperatures values, the UK climate records also confirm the legitimate dismissal of the argument that CO2 acts as a "control knob" - some type of global temperature thermostat that UN elite bureaucrats and national politicians thought they could just dial for a desired climate.
And that "warming" trend for the last 13 years that just scares-the-poopie out of UK's elites? A -4.8°C per century...yep, a significant cooling trend.
In summary, the combined CET and U.S. climate records add to the empirical evidence disproving the hyperbole for CO2-caused disastrous global warming and catastrophic climate change. In reality the hyperbole is without any scientific validation.
Damn those stubborn facts.

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

By year 2050, how much warmer will it be?
As the climate "experts" and $billion$ computer models have proven decisively, they are completely clueless when it comes to predicting future global temperatures.
Fifteen years ago, this graph's red curve, representing temperature trends, was tracking right along with the CO2 grey curve - such that, as of the end of September 1999, the 10-year temp trend was on a 2050AD warming pace of +1.1ºC.
But as the adjacent chart now reveals, by end of September 2014, that previous +1.1ºC trend has changed to a -0.03ºC cooling trend despite the continuous acceleration of atmospheric CO2 levels. A powerful testament to the overwhelming significance of natural climate change that far exceeds the influence of of a trace gas such as CO2.
And remember, not a single IPCC or NASA/GISS "expert" predicted this outcome - just the opposite in fact.
As the graph's red plot depicts, global warming trends have been on a deceleration path for an extended period, indicating a strong likelihood that global warming by 2050 will be nowhere close to he current official predictions.
Did we mention 'pussy cat' warming yet?
Obviously, the "settled" science of slam-dunk global warming is in shambles. And natural climate change made it so, much to the chagrin of those elites pushing "consensus" anthropogenic dogma.
Without doubt, in the scheme of urgent, priority issues facing the nation - global warming ain't one of them, which the American public already knows and reflects.
Every time there is a forest fire (ie wildfire) global warming alarmists, like a pack of Pavlov's dogs, start hysterically howling that human CO2 caused the recent incendiary event...while at the same time claiming their predictions of increasing wildfire damage from CO2-warming are coming true...however, like always, the empirical evidence proves the alarmists are without scientific portfolio.....
(click on graph to enlarge)
Let's cut to the chase - are human CO2 emissions causing an increase in U.S. forest acreage being decimated by flames?
The adjacent chart is a plot of U.S. wildfire acreage going back to 1926, through the end of 2013. The green curve represents acres burnt (in millions).
In addition, the chart includes the plot of lumber harvested (billion board-feet) from U.S. forests and atmospheric CO2 levels over the same approximate time span. The brown curve is the lumber harvest; the grey curve is CO2 (ppm).
What does the chart indicate?
Wildfire acreage burnt collapsed after the 1930s. Not only did this collapse coincide with a growth of atmospheric CO2 levels from human CO2 emissions, the huge decrease in acres burnt took place when the harvesting of lumber from U.S. forests grew massively.
Then, as the total amount of harvested lumber declined and reached a significantly lower level - due to new environmental regulations - the number of acres burnt each year started to incrementally increase during the 1990's.
Intuitively this makes sense. As the dead and disease-infected trees started to pile up from lack of harvesting due to environmentalist concerns and government regulations, the U.S. forests became wildfire tinderboxes, easily set off by lightening and human carelessness - the law of unintended consequences from passionate 'green' policies strikes again.
Per the statistical relationships, both board-feet harvested and CO2 levels have an inverse correlation (-0.6 and -0.5, respectively) with the acreage scorched, across the entire time span.
Conclusion: It's always dangerous to draw firm conclusions from just statistics, but the empirical evidence strongly suggests that both lumbering and higher CO2 levels makes for less wildfires. The record clearly shows that wildfire damage over the last two decades are not unprecedented, and it remains well below the horrendous amount of acres burned during the early 20th century. For policymakers, the sanest recommendation towards improving U.S. forest health is to increase the amount of allowed lumbering, thus thinning forests of tinderbox materials; plus, to recognize any future CO2 increases as a potential contributor to healthy forest growth.
Note: The wildfire acreage burned during years 1926-1959 and the lumber board-feet harvested came from this congressional testimony by scientific forestry expert; post 1959 data from this government agency site. CO2 datasets found here. The chart's right axis represents both atmospheric CO2 levels and harevested board-feet. For the latter, the largest number at the top, '1300', reads as 13 billion board-feet; for CO2, it would read 1,300 ppm.
The consistent failure of the IPCC's climate models is widely recognized by the scientific experts...the models inability to predict future climate scenarios accurately is partly a result of thousands of key failures, including their being unable to simulate the asymmetry of ENSO....
Besides the current crop of IPCC climate models failing due to their being CO2-centric, the models also suffer failure from the thousands of sub-simulations they are required to perform.
It is known that there exists a major asymmetry of the El Niños versus the La Niñas. If climate models can't accurately simulate this asymmetric relationship it makes for poor global climate predictions.
Scientists published a recent study to determine the success of modeling the ENSO asymmetry - the results were not encouraging.
===> "With respect to their findings, Zhang and Sun report the following: (1) "the underestimate of observed positive ENSO asymmetry measured by skewness is still a common problem in CMIP5 coupled models," (2) "all the models are also found to have a weaker ENSO asymmetry than observations," (3) "CMIP5 coupled models have a significant cold bias in the mean sea surface temperature," (4-6) "biases in zonal wind stress, precipitation and subsurface temperatures ... are also too symmetrical with respect to ENSO phases," (7) "sea surface temperature warm anomalies over the far eastern Pacific are found to be weaker in the coupled models than in observations," (8) "most models also have a weaker subsurface temperature warm anomaly over the eastern Pacific," (9) "most models have a weaker precipitation asymmetry over the eastern Pacific," (10) "most AMIP models have a stronger time-mean zonal wind over the equatorial central and eastern Pacific," and (11) they "underestimate the observed positive skewness of zonal winds in the central Pacific.""
Conclusion: The multi-billion $$ climate models have proven time and again that they are incapable of predicting future climate with any level of accuracy. Policymakers would be best served by completely ignoring the computer simulations as they poorly match the empirical observations of the global and regional climates. However, the models still hold value for the researchers, but that is their only benefit.
Another spectacular climate model & "expert" prediction failure...the abysmal predictions generated out of billion-dollar climate models are well documented...predictions for water levels of the Great Lakes are no better....
(click on chart to enlarge)
The vicious combination of climate "experts" driven by a political-alarmist agenda and the indisputably incompetent climate models has long misled the taxpaying public and policymakers.
As the NOAA chart of the Great Lakes on the left clearly indicates, water levels are above the long-term averages. The predicted "tipping point" water level reduction from global warming and climate change is AWOL.
The frequent and spectacular prediction failures of the computer simulations and experts has been widely noted in the past.
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.""
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 frigid tropical hotspot continues to be a massive embarrassment to the CAGW faithful, and more importantly, the climate modelers...their prediction of a runaway tipping point in the atmosphere that would produce Venus-like temperatures is a classic example of herd-style failure by the consensus algorithms....
(click on chart to enlarge)
Two recent studies demonstrate the absolute futility of policymakers listening to climate modelers (and their billion dollar climate models) who continually predict climate calamities - a prediction record with zero successes.
The first peer reviewed study determines that today's climate models will never be able to predict the climate. Essentially, climate models assume linear climate relationships yet the real-world climate is non-linear and chaotic - defying intermediate and long-term predictive "expertise" with predictable regularity.
The second study clearly documents the abysmal prediction failure foisted on the public and politicians by the climate modelers. The climate models have long predicted a tropical hotspot in the atmosphere due to CO2 emissions; but actual scientific research reveals that the feared, mythical, runaway "tipping point" hotspot remains non-existent.
The hotspot tipping point, per the climate modelers, is supposedly in the process of turning Earth's atmosphere into a Venus replica, making Earth uninhabitable. But is that realistically happening?
The adjacent chart provides the indisputable, empirical evidence to answer that question unequivocally - NO!
The chart's red column is the Venus atmosphere's temperature at the 10km altitude. A conservative estimated temperature is still an incredibly hot 350°C.
In contrast, the chart's dark blueish columns show the Earth's atmosphere at the same altitude is an incredibly frigid temperature of minus 75C degrees. Yes, our tropical atmosphere is some 425 degrees colder.
Ahem....what freaking Venus-like tropical hotspot?! IT DOES NOT EXIST.
Of course, the climate moderlers stuck-on-stupid-Venus, don't mention this amazingly obvious climate fact. Instead, they focus on how Earth's tropical atomosphere is "accelerating" towards a Venus-like hotspot tipping point.
Accelerating? Barely creeping at a glacial pace would be more accurate.
Examine the chart closely. Since the beginning of the 1980's, humanity has poured some 860 billion CO2 tonnes into the atmosphere; atmospheric CO2 levels keep climbing (see yellow boxes); yet, the average tropical atmospheric temperature has essentially not budged (see red dotted baseline) over 3+ decades of modern consumer/industrial human emissions.
The solution to climate science reality and better policy? 'TRUST NO ONE CLIMATE MODEL' should be stamped on every CO2-centric climate model prediction and report that is handed to politicians and policymakers.
Then this type of anti-science insanity preached by the climate modelers would finally be D.O.A., never again to poison a public scientific debate with "runaway" catastrophic climate absurdities.
Note: Source of approximate 10km Venus temperature; source of approximate Earth's troposphere temperature; source of approximate tropical latitude troposphere temperatures; source of lower tropical atmosphere temperature change since 1979; source of total CO2 emission tonnes since 1979; source of peak CO2 ppm levels for each decade.
The over-the-top predictions of catastrophic climate disaster from proponents of CAGW have become a public relations disaster for the establishment science community...the constant hyperbole about extreme climate change due to abrupt, accelerating and unequivocal global warming turns out to be without empirical, scientific merit, as the UK's recognized gold-standard global temperature dataset confirms....
(click on image to enlarge)
The lack of major hurricanes making direct landfall on the continental U.S. over the last 8+ years is a classic example of extreme climate change not happening as predicted.
Now, add to that the complete disappearance of statistically significant global warming - for the UK's HadCRUT4 there has been no statistically significant warming since October 1996; and for the RSS global atmosphere dataset, it has been since November 1992 - and one then begins to wonder about the incompetence of elite science.
The absence of climate significant warming by itself pretty much confirms that extreme climate change is a non-issue, deserving little priority and resources.
But, there is another view of extreme climate change that can be examined to ascertain whether it has become a modern era problem or not. This can be accomplished by examining simple 10-year absolute change events for global temperatures, both positive and negative.
By identifying the largest 20 warming events and 20 largest cooling events since 1850, the most extreme 2% of temperature swings can be placed in chronological significance. (This identification is best done with the IPCC's gold-standard, the UK's HadCRUT4 monthly dataset, which stretches back to 1850.)
The charts above provide the identification of these extreme, outlier temperature swings. (The May 2014 HC4 dataset contains 1,973 monthly observations from which 1,853 moving 10-year absolute change calculations can be derived.)
As is evident from the empirical data, the vast majority of extreme temperature swings (both warming and cooling) occur prior to 1960. Also, the charts' purple linear trend lines indicate that the extremes are shrinking (getting smaller, if you prefer) over time.
Conclusion: Human CO2 emissions have not caused the predicted abrupt, accelerating and unequivocal global warming during the modern era, as all of the above scientific evidence attests. In addition, the lack of extreme climate change disasters and shrinking temperature swings, in relation to the past, actually indicate there may be an inverse relationship with growing CO2 emissions and atmospheric levels.
Now that would truly be mind-boggling, and help explain why "consensus" scientists are so befuddled and at a loss. Of course, stranger things have happened, such as the recent admission by consensus establishment science that they have been horribly wrong (for three decades, yikes!) about dietary cholesterol and saturated fat causing heart disease.
However, with all the above stated, this does not mean that climate change is not happening; that human activities have no influence on weather and climate; nor that global warming won't occur in the near future.
Note: UK's HadCRUT4 2014 satellite dataset used in Excel to calculate 10-year absolute (i.e. arithmetic difference) temperature changes and linear trends for above charts. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
Are humans turning Earth into another Venus, an inhabitable planet with temperatures hotter than your Weber grill on the 4th of July? Well...when the empirical dots are connected the scary Venus fate for Earth goes poof....
(click on chart to enlarge)
In a previous post, empirical observations documented the lack of both short-term and long-term warming of the atmosphere.
Another approach to assessing the atmosphere's temperature change is to examine the 10-year changes in the lower troposphere. The graph on the left plots such changes.
Using a satellite dataset that contains 426 monthly temperature measurements, 306 moving 10-year changes can be calculated. This graph plots those 306 data-points (the proverbial 'dots'), plus the cumulative growth in CO2 levels over the same period.
Visually, it is obvious the 10-year temperature changes were dominated by increasing values up till the early 2000's. After that, the 10-year changes decreased consistently, turning from positive to negative. The graph depicts the global atmosphere actually cooling over recent time.
The long increase in 10-year temperature change, and then its subsequent decrease, is confirmed by both the 3-year simple average curve (aqua) and the fitted trend curve (6th order polynomial).
The pale green curve (another fitted trend curve, 6th order) represents the unabated, relentless cumulative growth of atmospheric CO2 levels.
Conclusion: Earth is not turning into Venus. The experts' predictions that human CO2 emissions would turn Earth's atmosphere into a simmering Venus lookalike, resulting in "boiling" oceans, is now substantiated as a crackpot, global warming bogosity - pure anti-science alarmism that was promulgated by establishment science.
Does the above mean that Earth's atmosphere will never warm again? Nope, it will indeed continue to have phases of warming and cooling just as it did in the past, sans Venus conditions, though.....because that is what climates do, just naturally.
Note: RSS June 2014 satellite dataset used in Excel to calculate 10-year temperature changes. fitted trends and 3-year average in the above chart. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
WUWT produces another example of the elite establishments' propaganda promoting bogus climate change alarmism. There is little, if any, empirical evidence of the climate refugee claim, unless one actually believes the output of egregiously error-prone climate computer models.
Instead of educating its readers about global warming reality, the Smithsonian delivers typically lame press release "science," enhanced with hyperbolic statements, which have been thoroughly debunked in the past.
Personally, I canceled my Smithsonian subscription over a decade ago after tiring from their constant anti-empirical, political-agenda science. But for those who still do subscribe, one might want to keep this infograph handy to help spot the magazine's bogus claims and bad science reporting.
For your added pleasure, obvious additional speculative hyperbole from the magazine:
====> "Other health threats have been enumerated by Robert Repetto, a United Nations Foundation economist, who says climate change will intensify smog, leading to “increased outbreaks of asthma and allergies,” and “exacerbate vector-borne diseases such as hantavirus, West Nile virus, Lyme disease and dengue fever.” Repetto also worries about the “extreme weather events” that some researchers say climate change will engender...Heat waves themselves pose a health risk, especially for young children and the elderly—and world-class athletes...Even people who don’t have to move will experience a bewildering sense of dislocation as the environment changes around them—as Northern winters start to be measured in weeks rather than months."
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.
