“This is perhaps the most accessible book that I have ever read about how humanity is changing Earth’s climate, and what can be done about it.”

David Archer, author of Global Warming: Understanding the Forecast

"Calvin approaches climate change as a sensible doctor would: if a patient has unusual symptoms, and medical science points to a risk of a horrible disease, therapy should begin without delay. For decades climate scientists thought they were doing enough by pointing out a risk, while symptoms grew ever more ominous. But as doctors know, patients with signs of cancer often deny it, putting off action until it is terribly costly and uncertain. Global Fever is a timely effort to combat such denial of the danger of climate change."

Spencer Weart, author of The Discovery of Global Warming

“Calvin dissects the ongoing controversies over global warming like a master surgeon. Global Fever offers a sobering diagnosis for the future and a realistic assessment of effective strategies for living with the major climatic changes that are humanity’s destiny.”

Brian Fagan, author of The Long Summer: How Climate Changed Civilization

“It needs a physician to look at the patient that is our Earth, to make a diagnosis, to measure its rising temperature, to look at the reasons for it, to assess the likely effects, and not least to suggest what now needs to be done. William Calvin’s new book does all this and more in simple and telling language. Above all Calvin brings out the need for urgent action if the wonderful Earth that we have inherited will be as wonderful for our children and generations to come.”
