This former EPA scientist and economist smashes the AGW agenda, in this hard hitting post. Alan Carlin writes (cross posted at Icecap): New Report Definitively Shows UN CAGW Hypothesis and IPCC Reports Invalid and Thus CPP and Paris Treaty Total Wastes
As discussed in my book, Environmentalism Gone Mad, two of the reasonable inferences from the Catastrophic Anthropogenic Global Warming (CAGW) hypothesis (the scientific basis for the world climate scare pushed by the United Nations and the Obama Administration) are that atmospheric carbon dioxide (CO2) levels should affect global temperatures, and that the resulting heat generated should be observable by a hot spot about 10 km over the tropics. In fact, the United Nations Intergovernmental Panel on Climate Change (UNIPCC) argues that both should exist and the US Environmental Protection Agency (USEPA) uses the hot spot as one of its three “lines of evidence” for justifying its Greenhouse Gas (GHG) Endangerment Finding (EF).
The EF, in turn, is used by EPA to justify all its climate regulations, including its ultra-expensive so-called “Clean Power Plan” (CPP} requiring that many coal plants be replaced with wind and solar-generated electric power at huge expense to ratepayers in terms of outlays and reductions in reliability as well as to taxpayers for government subsidies. The 2016 Democratic Party Platform last July now carries this approach to a new extreme by advocating that all use of fossil fuels be ended by 2050, which is highly unlikely to even be achievable at any cost.
Climate skeptic scientists have long questioned whether the effects of relatively minor (compared to other CO2 sources and sinks) human-caused emissions of CO2 have more than a minor effect on global temperatures and some have even questioned whether the UN and USEPA have even gotten the causation backwards (i.e., because on balance global temperatures affect atmospheric CO2 levels). A very interesting new study shows that their skepticism has been more than justified. By using sophisticated econometric/statistical methods on 13 different climate databases for the years 1959 to 2015 where available, the study concludes that the changes in CO2 have no measurable net effects on global temperatures but that global temperatures affect CO2 levels. The real advance in the new study is that it assumes that global temperatures may affect atmospheric CO2 levels in addition to assuming that CO2 may affect global temperatures (as assumed by UNIPCC and USEPA). This introduces complexity to the analysis but is a crucial improvement over most earlier studies.
