Five ways Joe Rogan misleads listeners about climate changeย  ยป Yale Climate Connections Rogan exposes millions to climate denial. Letโ€™s break down his tactics.

Joe Rogan has one of the world's most popular podcasts. Unfortunately, like nearly all of the most popular online shows, his tends to spread climate misinformation. For @climateconnections.bsky.social I scrutinize his recent episode with octogenarian climate contrarians Lindzen & Happer ๐Ÿงต (1/11)

Itโ€™s complementary, thereโ€™s no single magic bullet against misinformation which is a complex, interconnected problem requiring multi-pronged solutions. We need better mindsets, critical thinking and BS detection, media literacy and more
