US Signee Andy May published his second book about climate change: Politics and Climate Change: A History. In this book May focuses on the politicians and organisations that influenced the climate debate, such as Al Gore, the EPA and Greenpeace. A central theme in the book is the corruption of science as a result of government funding. May: “Government money clearly does not improve research, the theoretical estimates of the impact of manmade CO2 have not narrowed in 41 years, as we discussed in our last two posts, here and here. Despite billions in government spending, the IPCC AR5 report (IPCC, 2013) still says the impact of doubling CO2 is between 1.5°C and 4.5°C, exactly the same range given in the Charney Report (Charney, et al., 1979). Empirical observation-based estimates, like the one by Nic Lewis and Judith Curry (Lewis & Curry, 2018), have narrowed, but these were not government funded. The funding did not improve science, it was not intended to improve the science, it was political.”
May posted several excerpts from his book on the CLINTEL website, here, here, here and here.
