We are here for trees . No research allowed <| sep |> Yes . I have . I found Nature Bats Last after reading Lynas ' Six Degrees . Some of McPherson ' s points are indisputable . Sea Ice Melt , Global Dimming ! !!, and Methane Release is absolutely happening . The feed backs which have been identified , given enough time , will happen . Global Dimming will roll back overnight when we get our soon to hit us economic collapse due to missing cheap hydrocarbon inputs . However , he misses Negative feed backs , and there are a few , but they are trivial in comparison to the Positive feed backs . I suspect that people who immediately dismiss McPhereson are not familiar with Bartlet ' s We dont understand exponential function series . FQA 2 rkpBSYEdit In Lynas ' s Six Degrees , he had collected over 2000 papers provided by science and created an overview at what we could expect at 1 , 2 , 3 , 4 , 5 , and 6 degrees . At three degrees , civilization wont exists on this planet , although a very small number of people might be able to eek out an existence . We are well past one degree , and a Global Dimming rollback will provide over two extra degrees in a blink of an eye .
