This book offers closely reasoned statistical analysis of major themes to limit global warming and finds that many of them are not warranted after the math has been worked through. He argues for instance the Paris Accords will cost 500 trillion dollars. The benefit is to lessen global warming by less than one degree over the next eighty years. Most environmentalism is about virtue signaling and little thought is given to actual benefits. This book does very careful cost benefit analyses and tosses many dumb ideas such as the stoppage of fossil fuels suggested by hysterics like AOC and Greta Thornburg. He says wind and solar would finish our energy grid off in less than a minute. Sentimental foolishness helps no one. This a tough minded and pragmatic author whose ideas will save the world endless tragedy imposed by well meaning saps like Al Gore and Joe Biden.
