The report is entitled Proposed NCEE Comments on Draft Technical Support Document for Endangerment Analysis for Greenhouse Gas Emissions under the Clean Air Act and is written by Alan Carlin and John Davidson in what must have been a very courageous act in opposition to the clear political will of EPA management. Among other things the report shows that:
- The EPA and many other agencies and countries have paid too little attention to the science of global warming.
- The EPA decision that CO2 is a pollutant is based on the IPCC AR4 report, which is three years out of date.
- Global temperatures have declined for 11 years, particularly rapidly in 2007 and 2008, even as CO2 emissions increased rapidly.
- The concensus on Atlantic storm severity is now that there will be little change in storm severity.
- There is little evidence in new research results that Greenland will rapidly lose its ice mass.
- One of the worst economic recessions since WWII has greatly decreased CO2 emissions relative to the U.N. estimates.
- The Pacific Decadal Oscillation and the El Nino Southern Oscillation are the best single predictors of global temperature fluctuations.
- There is a strong association between solar sunspots and irradiance and global temperature fluctuations.
- The satellite temperature record starting in 1978 shows that changes in greenhouse gas concentrations have very little effect upon the temperature.
- Surface temperature measurements (HADCRUT) appear more likely due to the influence of the Urban Heat Island Effect than to increased greenhouse gas concentrations.
- The 1998 temperature peak is not understood, though it appears in both the satellite and surface temperature records. What natural effect caused it? When we do not understand such things, how can be assess the comparative effects of CO2 emissions?
