In the third episode of In Defense of Climate Change, Bryce Nickels and climate policy scholar Roger Pielke Jr. revisit the legacy of An Inconvenient Truth twenty years after its release. Building on Pielke’s recent essay about the film, they examine how Al Gore framed climate change through a religious lens—apocalyptic warnings, moral imperatives, and a defined path to “salvation.” Pielke reflects on how readily much of the scientific community embraced this framing and argues that the film’s most enduring impact lies not in any single claim it made, but in how it helped recast climate science as a vehicle for moral and political advocacy.
A central theme is the concept of “new apocalypticism,” drawn from the work of sociologist Michael Barkun, which Roger uses to describe how scientific authority has been repurposed to support secular narratives of impending catastrophe. He argues that An Inconvenient Truth exemplifies this shift, presenting complex scientific issues through emotionally charged imagery and moral binaries that divide the world into good and bad actors. Bryce highlights specific examples from the film—including its use of extreme weather events, historical analogies, and symbolic imagery—to argue that it relies heavily on persuasion rather than careful scientific reasoning.
The episode also examines what the film got right—such as the basic science of greenhouse gas emissions and warming—while emphasizing where it misled audiences, particularly on extreme weather and the role of political will. Roger argues that the film’s biggest error was its claim that solving climate change is primarily a matter of political motivation, rather than a challenge of technological innovation and economic alignment. More broadly, the conversation explores how the blending of science and advocacy can erode public trust, especially when scientific institutions adopt partisan or moralizing narratives.

About the Series
In Defense of Climate Change features conversations between climate policy scholar Roger Pielke Jr. and Rutgers professor and Science From the Fringe host Bryce Nickels. The series examines one of the most politically polarized areas of modern science—what the evidence actually shows about climate change, and how those findings are interpreted, amplified, and sometimes distorted once they enter politics and the media. By focusing on data, historical context, and intellectual honesty, the conversations aim to cut through extreme narratives and separate the underlying science from the stories that often dominate public debate.
