Roy W. Spencer’s The Great Global Warming Blunder: How Mother Nature Fooled the World’s Top Climate Scientists is by an evangelical who is the lead scientist on the EMSR (remote sensing) program of NASA’s Aqua satellite system and principal research scientist in climatology at the University of Alabama at Huntsville.
Both Spencer and McKitrick are on Cornwall Alliance’s advisory board and have contributed to papers we have produced.
One of the most common reasons for believing in dangerous, manmade global warming is that, allegedly, an overwhelming consensus of scientists believes in it and this consensus is represented by the IPCC, allegedly the world’s leading authority on the topic. These reasons commit the logical fallacies of
argumentum ad populi (popular vote) and
argumentum ad verecundiam (appeal to authority). Neither consensus nor authority is valid in scientific debate, which focuses on data and theory.
