The Science and Environmental Policy Project issues weekly reports on their website at www.SEPP.org on new findings on the issues associated with Global Warming/Climate Change. You can find the latest complete 22-page report here. What I find remarkable about this report is their findings on CO2 as the cause of man made global warming. Here is the excerpt. You can peruse the report itself for more information.

Is the Claim of CO2-Causing Dangerous Global Warming Obsolete?
As discussed in prior TWTWs, (e.g. Nov 12 & 19) the highly influential 1979 Charney report contained an estimate that a doubling of carbon dioxide (CO2) would cause a warming of the earth’s surface of 3ºC ± 1.5 ºC (roughly 6ºF ± 3ºF). The report presented the assumption by climate modelers that the very modest warming by CO2 demonstrated by laboratory experiments will be amplified several times by a warming caused by water vapor taking place in the atmosphere over the tropics centered about 10 km, 33,000 feet – the so-called “hotspot.” Given the lack of data in 1979, there was no way to confirm or deny this important assumption and the findings. The findings of the Charney Report of 3ºC ± 1.5 ºC have been repeated, with minor modification, in all five Assessment Reports (ARs) of the UN Intergovernmental Panel on Climate Change (IPCC) with no other explanation why CO2 warming occurring in nature will greatly exceed the warming found in the laboratory. These IPCC reports date from 1990 to 2014, with a sixth report underway. In general, the global climate models have the same results, but due to their incomprehensibility, it is not clear if the models use some other mechanism to arrive at the result. The February 2 testimony by John Christy included comprehensive satellite data of global temperatures covering 37 years (from December 1978 to the end of 2015) of the atmosphere from the surface to 50,000 feet. These data demonstrated that a speculated, pronounced warming of the atmosphere from water vapor does not exist. After over 35 years of speculation, 25 years of IPCC reports, multiple US government reports, and US government estimates that it spent over $40 Billion on climate science since 1993, and it spent over $150 Billion on activities to “fight global warming”; it is past time to produce physical evidence that the amplified atmospheric warming from increased water vapor exists. If the evidence is not produced, the hypothesis that human emissions of CO2 will cause dangerous global warming is as obsolete as peak oil theory, or that the sun is immutable, unchanging.
