Life at CO² below 310 ppm – July, 1936
The summer of 1936 was by far the hottest summer in US history
The EPA reports the same thing
Heat waves occurred with high frequency in the 1930s, and these remain the most severe heat waves in the U.S. historical record (see Figure 1).

“We’ve got to ride this global warming issue.
Even if the theory of global warming is wrong,
we will be doing the right thing in terms of
economic and environmental policy.”
– Timothy Wirth,
President of the UN Foundation
“Isn’t the only hope for the planet that the
industrialized civilizations collapse?
Isn’t it our responsiblity to bring that about?”
– Maurice Strong,
founder of the UN Environment Programme
“In my view, after fifty years of service in the United Nations system,
I perceive the utmost urgency and absolute necessity for proper
Earth government. There is no shadow of a doubt that the present
political and economic systems are no longer appropriate
and will lead to the end of life evolution on this planet.
We must therefore absolutely and urgently look for new ways.”
– Dr Robert Muller,
UN Assistant Secretary General,

Bummer! Now, just before members of the U.N.’s Church of the Burning Planet are scheduled to finalize their latest hellfire and brimstone sermon, a chilling development has occurred. A flood of blasphemous reports circulated among ranks of former faithful parishioners are challenging human-caused climate crisis theology.
On September 23 through 26, representatives of the world’s Environment Ministries will meet in Stockholm to agree on the final draft of a key portion of the latest Intergovernmental Panel on Climate Change (IPCC) Summary for Policymakers gospel which is expected, once again, to keep the political climate cauldron steaming. This Fifth Assessment Report (AR5) is intended to be used by international ministers working to devise a new global treaty by 2015 to curb “climate change”.
That goal is certainly no trifle, given that dramatic climate changes have been occurring over many millions of years, although
lately…not so much. Therein lies the big rub. How can ministers conjure up a newsworthy sequel to previous knuckle-biting prognostications when all evidence suggests that the prophesies, and the scriptures they were based upon, were proven wrong?
Remember that really scary “hockey stick” graph IPCC used to show that rising atmospheric CO2 concentrations would send global temperatures soaring? And recall all the ballyhoo about CO2 levels reaching a 400 ppm record high? Yet last February even IPCC’s chairman Rajenda Pachuri has admitted that world temperature data has been flat for the past 17 years. And that was after the British media reported that the UK Met Office was projecting a 20-year standstill in global warming by 2017.
You certainly know the jig is up when the New York Times finally recognizes that the feverish climate fervor is overheated. They reported on June 6 that“The rise in the surface temperature of Earth has been markedly slower over the last 15 years than in the 20 years before that. And that lull in warming has occurred even as greenhouse gases have accumulated in the atmosphere at a record pace.”Reporter Justin Gillis went on to admit that the break in temperature increases “highlights important gaps in our knowledge of the climate system”, whereby the lack of warming “is a bit of a mystery to climate scientists.”
Where, Oh Where, Has that Global Warming Gone?
One highly plausible answer to this mystery is that the climate models upon which IPCC’s failed projections are based exaggerate climate sensitivity to CO2, underestimate known natural forcings, and simply don’t understand how to factor in and calibrate other influences such as ocean cycles and solar activity. Numerous recent scientific papers suggest that overestimation of sensitivity by at least 30% may account for much of the problem. If so, a reduction of 30% would leave lots of missing heat which must have been offset by natural cooling.
After all, the importance of those natural influences shouldn’t be that surprising given that history shows that temperatures have been higher when CO2 levels were lower, and vise versa. In fact, the past century has witnessedtwo generally accepted periods of warming The first occurred between 1900 and 1945. Since CO2 levels were relatively low then compared with now, and didn’t change much, they couldn’t have been the cause before 1950.
The second possible very small warming, following a slight cool-down, may have begun in the late 1970s lasting until 1998, a strong Pacific Ocean El Niño year. Yet even if global temperatures actually did rise very slightly during that second period, the U.K. Hadley Center and U.S. NOAA balloon instrument analyses fail to show any evidence, whatsoever, of a human CO2 emission-influenced warming telltale “signature” in the upper troposphere over the equator as predicted by all IPCC global circulation models. In fact, about half of all estimated warming since 1900 occurred before the mid-1940s despite continuously rising CO2 levels since that time.
So Maybe the Models Are Broke…Not the Climate After All!
According to a recent Opinion & Comment piece titled “Overestimating global warming over the past 20 years” that appeared in Nature Climate Change, the model-based fear and loathing attached to global warming may be substantially overheated. Notably, Francis W. Zwiers, one of the three authors, is a vice-chair of this relevant section for AR5. The writers observe that whereas the global mean temperature over the past 20 years (1993-2012) rose at a rate of between about 0.14o–0.06oC per decade, average temperatures computed by 117 simulations of 37 climate models predicted a surface temperature rise of 0.30o-0.02o C per decade. The observed rate of warming was less than half of the simulated rate.
The inconsistency between observed and simulated warming was even greater over the past 15 years (between 1998 and 2012). Here the observed trend was 0.05o-0.08oC per decade, vs. the average simulated trend of 0.21o-0.03oC. The observed trend was four times smaller. The divergence began in the early 1990s. Accordingly, evidence indicates that the group of model simulations do not reproduce observed global warming over the past 20 years, or the slowdown over the past 15 years. Keep Reading »

Guest essay by Christopher Monckton
As soon as the BBC/Maslowski forecast of no sea ice in the Arctic summer by 2013 has been disproven (see countdown on right sidebar), WUWT will need another countdown. May I propose the Santer countdown?
On November 17, 2011, Ben Santer and numerous colleagues, including researchers from Remote Sensing Systems (RSS), published a paper in the Journal of Geophysical Research (Atmospheres) that, as his press release said,
“shows that climate models can and do simulate short, 10- to 12-year “hiatus periods” with minimal warming, even when the models are run with historical increases in greenhouse gases and sulfate aerosol particles. … tropospheric temperature records must be at least 17 years long to discriminate between internal climate noise and the signal of human-caused changes in the chemical composition of the atmosphere.”
In an earlier posting I demonstrated that for more than 17 years (now 17 years…

By far the largest number of local glaciers in north-east Greenland had receded very greatly during recent decades, and it would not be exaggerating to say that these glaciers were nearing a catastrophe.
Fortunately, NASA has recently erased the 1940 warm period in that region, retroactively saving the glaciers.
