Document Summary
Cool the earth, save the economy: solving the climate crisis is easy. Chapter 1: truths and myths about global warming. 4 distinct patterns of warming: polar areas warming faster than middle latitudes, winter temperatures rising faster than summer temperatures, night-time temperatures rising faster than daytime temperatures, lower atmosphere is heating while upper atmosphere (stratosphere) is cooling. Last 2 clues tell us that it is release o heat-trapping gases by humans, not brighter sun. Myths about global warming: (1) satellite data contradict the evidence for a warming trend. Yes upper atmosphere (stratosphere) cooled overly last decades indicated by satellite data. But this is actually sign of global warming (2) prehistoric climate change was much greater than now, so don"t worry. If keep emitting co2 emissions, warming expected in next 100 years will be same magnitude as climate changes occurring over past millions of years.
