This could be the very worst book that I have ever had to endure. Lee McIntyre is a global warming consensus zealot who attacks climate change skeptics (the number of actual deniers is really quite small) by trying to link them to people who believe in intelligent design (evolution deniers) and/or flat Earthers which is only guilt by association a form of McCarthyism. This attempted coupling is Mr. McIntyre's method for selling an environmental program that is at best flimsy. For example, as a climate change denier, I am personally aware of 4,000 scholarly scientific research papers that have all been published over the last five years in top-notch peer-reviewed journals that each "falsify" (Karl Poppers' standard) the anthropogenic global warming theory.
In an effort to demonstrate how trivial Mr. McIntyre's book is one need only examine his bibliography which is made up largely of newspaper and magazine articles all from left-wing sources. 
Looking at McIntyre's body of work also shows his unserious research efforts. The books of his that I have read include his own works (Post-Truth) in which he tracks how intelligent design proponents and climate deniers draw from postmodernism to undermine public perceptions of evolution and climate change and several nonsense books by Washington Post reporter Chris Mooney. 
In 2015 McIntyre wrote in the Price of Denialism that "True skepticism must be more than an ideological reflex; skepticism must be EARNED by a prudent and consistent disposition to be convinced only by evidence."  (Emphasis in the original) Of course, McIntyre does not understand that a single replicable contrary finding according to Popper is enough to "falsify" any theory. Over 4,000 such findings in just five years are simply overwhelming! And yet McIntyre can not fathom why public belief in climate change is declining. 
Mr. McIntyre also cites Elizabeth Kohut's article about facts not mattering but fails to realize that Kohut's credentials are at best sketchy and that she authored the March 12, 2018 article in National Geographic (There's No Scientific Basis For Race) which does not contain a single correct factual assertion. The scientific basis for race is today so extensive that any form of denial is perverse.
The bottom line is that How to Talk to a Science Denier is actually worth only MINUS five stars but Net Galley makes me award it one star. McIntyre's books are all complete loads of crap. To paraphrase H. L. Mencken -- Dealing with an ideologue like Lee McIntyre can be a very messy process.

This book is a wonderful diatribe if you consider science to be a religion you either believe in or don't. 

On the other hand if you consider science in its historical context, where many scientific theories are eventually shown to be misleading, this book is as naive as they come. 

Of course flat earthers don't conform to evidence and logic. Neither does this book.
