In this free book, I take a different approach. I use examples from the history of science in which scientists collectively have been wrong to see whether they could be making the same sort of mistakes today about global warming. It is short and can be read in a couple of hours.
I also examine a sample of the evidence that convinces scientists that they are not wrong about global warming. I discuss the reliability of the computerized climate models that scientists use to project into the future. Finally I assess whether, as many people believe, scientists substantially disagree about global warming.
