Despite the expected predictable dismissal of the author by some on this forum already - the WSJ states "Mr. Koonin’s science credentials are impeccable—unlike, say, those of one well-known Swedish teenager to whom the media affords great attention on climate matters. He has been a professor of physics at Caltech and served as the top scientist in Barack Obama’s Energy Department. The book is copiously referenced and relies on widely accepted government documents.
"Mr. Koonin (The book's author) is no “climate denier,” to use the concocted phrase used to shut down debate. The word “denier” is of course meant to associate skeptics of climate alarmism with Holocaust deniers."
"Mr. Koonin is persuasively skeptical. It’s a big problem, he says, when models can’t retroactively “predict” events that have already happened. And he notes that some of the “tuning” done to models so that they work better amounts to “cooking the books.”
"But science itself is not conducted by polls, regardless of how often we are urged to heed a “scientific consensus” on climate. As the science-trained novelist Michael Crichton summarized in a famous 2003 lecture at Caltech: “If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period.”
“Heat waves in the US are now no more common than they were in 1900” and “the warmest temperatures in the US have not risen in the past fifty years"
"Humans have had no detectable impact on hurricanes over the past century"
Greenland’s ice sheet isn’t shrinking any more rapidly today than it was eighty years ago"
"But even if one remains unconvinced by his arguments, the right response is to debate the science. We’ll see if that happens in a world in which politicians assert the science is settled and plan astronomical levels of spending to replace the nation’s massive infrastructures with “green” alternatives. Never have so many spent so much public money on the basis of claims that are so unsettled. The prospects for a reasoned debate are not good. Good luck, Mr. Koonin."
