Contrary to polls, politicians, and many pundits, the science of climate change is clear. Anthropogenic climate change is under way, as expected from burning fossil fuels that accumulated over milennia and as predicted by naturalist and diplomat George Perkins Marsh in 1847. Nearly 50 years later, Swedish chemist and Nobelist Svante Arrhenius spelled out the dire consequences likely to result from burning fossil fuels in a refereed journal article. Then in 1990, the United Nations Advisory Group on Greenhouse Gases reported, “Beyond 1 degree C may elicit rapid, unpredictable and non-linear responses that could lead to extensive ecosystem damage.” Planetary instruments indicate Earth has warmed about 1 C since the beginning of the industrial revolution. Not surprisingly, numerous self-reinforcing feedback loops have been triggered, indicating climate change is irreversible.
