Summary

In this episode of Climate Book Reviews, hosts Ed Whittingham and Roger Thompson interview John Vaillant, author of ‘Fire Weather’, about the 2016 Fort McMurray wildfire and the broader phenomenon of megafires. Vaillant explains how wildfires are becoming a new form of weather, generating their own lightning and wind, and releasing energy that is unsurvivable. He discusses the science behind firestorms, the role of climate change, and the historical failure of the oil industry to act on climate warnings. The conversation also covers the concept of the ‘Pyrocene’ age, the limitations of firebreaks against firestorms, and the need for a shift in consciousness. Vaillant highlights community responses, such as firebreaks in Canmore, and the importance of attribution science. The episode concludes with a discussion of hope and the potential for legal action against disinformation.

Critical Evaluation

Value of the Information & Strength of the Argument

The value of the information is high, as it provides a compelling narrative and expert insights into the science of megafires and their connection to climate change. Vaillant’s argumentation is solid, drawing on his extensive research and firsthand accounts. He effectively explains complex concepts like pyrocumulonimbus clouds and fire tornadoes, making them accessible to a general audience. The discussion is well-structured, moving from the specific Fort McMurray fire to broader implications for society. The hosts add value by contextualizing the conversation within current climate debates and referencing other experts.

Scientific Rigor, Source Quality, Title Accuracy

The scientific rigor is strong, as Vaillant’s book is well-researched and he cites specific historical events and scientific studies. The sources mentioned include the 1968 Stanford Research Institute article, the 1959 Energy and Man conference, and the work of Stephen J. Pyne. The title accurately reflects the content, focusing on the new era of megafires and their weather-generating capabilities. The discussion is consistent with established climate science, though it is presented from an expert opinion perspective rather than as a formal scientific review.
