PhD physicist Ralph B. Alexander has authored a new book: Science Under Attack: The Age of Unreason.
What follows is a taste of what readers can expect from the book. Ideal present for the upcoming Christmas season.

Conventional scientific wisdom holds that global warming and consequent changes in the climate are primarily our own doing. But what few people realize is that the actual scientific evidence for a substantial human contribution to climate change is flimsy. It requires highly questionable computer climate models to make the connection between global warming and human emissions of carbon dioxide (CO2).
No proof warming is human caused
The multiple lines of evidence which do exist are simply evidence that the world is warming, not proof that the warming comes predominantly from human activity. The supposed proof relies entirely on computer models that attempt to simulate the earth’s highly complex climate and include greenhouse gases as well as aerosols from both volcanic and man-made sources – but almost totally ignore natural variability.
Models way off mark
So it shouldn’t be surprising that the models have a dismal track record in predicting the future. Most spectacularly, the models failed to predict the recent pause or hiatus in global warming from the late 1990s to about 2014. During this period, the warming rate dropped to only a third to a half of the rate measured from the early 1970s to 1998, while at the same time CO2 kept spewing into the atmosphere. Out of 32 climate models, only a lone Russian model came anywhere close to the actual observations.
