I believe climate change is real and that human emissions of greenhouse gases risk justifying action, including a carbon tax. But my research led me to a conclusion that many climate campaigners find unacceptable: There is scant evidence to indicate that hurricanes, floods, tornadoes or drought have become more frequent or intense in the U.S. or globally. In fact we are in an era of good fortune when it comes to extreme weather. This is a topic I’ve studied and published on as much as anyone over two decades. My conclusion might be wrong, but I think I’ve earned the right to share this research without risk to my career.
Instead, my research was under constant attack for years by activists, journalists and politicians. In 2011 writers in the journal Foreign Policy signaled that some accused me of being a “climate-change denier.” I earned the title, the authors explained, by “questioning certain graphs presented in IPCC reports.” That an academic who raised questions about the Intergovernmental Panel on Climate Change in an area of his expertise was tarred as a denier reveals the groupthink at work.
Yet I was right to question the IPCC’s 2007 report, which included a graph purporting to show that disaster costs were rising due to global temperature increases. The graph was later revealed to have been based on invented and inaccurate information, as I documented in my book “The Climate Fix.” The insurance industry scientist Robert-Muir Wood of Risk Management Solutions had smuggled the graph into the IPCC report. He explained in a public debate with me in London in 2010 that he had included the graph and misreferenced it because he expected future research to show a relationship between increasing disaster costs and rising temperatures.
When his research was eventually published in 2008, well after the IPCC report, it concluded the opposite: “We find insufficient evidence to claim a statistical relationship between global temperature increase and normalized catastrophe losses.” Whoops.
