Michaels is a climatologist who refuses to join the Chicken Little Anti-Warming Club (CLAWC), even though there is a lot of federal money to be had for those who are willing to join the flock. He grants that, as has happened in the past, the earth is going through a moderate warming cycle; he denies with mind-numbing thoroughness that the warming trend is caused by industry, that it could be reversed by destroying industry, and that the added warmth will have such destructive effects that no intelligent species could adapt to the changes. He does not directly address the question whether such an intelligent species is to be found on this planet.
For good or for ill, I read this book in a Kindle edition, which means that I did not have the color insert to which he refers many times, nor could I make a great deal of sense out of the other charts and figures that he supplied to make his case. The book is slightly dated by its references to the 2004 election cycle, but even were those remarks removed, it still would be a period piece because of the torrent of data produced by $20,000,000,000 of global warming grants given to the CLAWC.
