With the U.N. Paris Climate Conference (December 2015) in the headlines, and climate policy a hot topic in the election cycle, it has become increasingly difficult to differentiate the climate science from the rhetoric. In Lukewarming: The New Climate Science that Changes Everything, two environmental scientists with over a half century of experience between them explain the science and spin behind the headlines and come to a somehow provocative conclusion: climate change is real, and partially man-made, but it is becoming obvious that far more warming has been forecast than is going to occur, and some of the catastrophic impacts can be shown to be implausible or impossible. Global warming is more lukewarm than hot. This fresh analysis is engaging and enlightening to readers of all backgrounds, and provides an invaluable briefing to those looking to be more informed citizens.
