On the next Your Call, investigative climate journalist Geoff Dembicki joins us for part 2 of our conversation about his new book, The Petroleum Papers: Inside the Far Right Conspiracy to Cover Up Climate Change. Using hundreds of confidential industry documents, he reveals how American oil companies have ignored warnings about climate devastation since as early as 1959. These companies have spent billions to spread disinformation and climate denial, undermine international treaties, and help elect Donald Trump. We'll also discuss how these efforts to conceal the climate crisis have impacted recent negotiations at the COP27 UN climate conference, where negotiators failed to reach an agreement to phase out fossil fuels or limit temperature increases to 1.5 °C.
