Lack of Evidence: For the past several weeks, TWTW has addressed the evidence supporting EPA’s finding that human greenhouse gas emissions, particularly carbon dioxide (CO2), endanger human health and welfare (EPA Endangerment Finding). We found little or no physical evidence supporting the finding. Without this finding the EPA has no legal basis for regulating CO2, and the administration has no logical basis for its energy plan of eliminating coal-fired power plants through CO2 regulations. These regulations are based on a controversial 2007 Supreme Court decision stating that CO2 is a pollutant under the Clean Air Act, even though it is not a defined category pollutant. According to the decision, before regulating, the EPA must find greenhouse gases (particularly CO2) endanger public health.

The five assessment reports (ARs) of the UN Intergovernmental Panel on Climate Change (IPCC) produce some excellent science, but also misleading assertions. The so-called “hot spot”, mistakenly called the distinct human fingerprint in IPCC’s second assessment report of Working Group I (AR-2 1995), has not been found to exist. There is no discernible increase in atmospheric warming trends over the tropics centered at about 33,000 feet. (Note: it is the warming trends over time, increasing with altitude, that are important. A lapse rate, the decline in actual temperatures with increasing altitude would still be observed, but the rate should decline over time.) In fact, the AR-2 synthesis report, which followed the Working Group I report, makes no mention of the hot spot in the section titled: “The Balance of Evidence Suggests a Discernible Human Influence on Global Climate.” (p. 22).
