At COP29 in Baku, Azerbaijan, running until November 22, scientists express alarm over the politicization of science in climate negotiations. Experts worry that some states are trying to undermine the importance of scientific reports from the IPCC, jeopardizing the basis for addressing climate change. Veteran researcher Pamela Peterson highlights unprecedented attacks on scientific consensus, while others, like Marine Pouget, criticize oil-dependent countries for resisting updated climate data for their own interests. The outcome could significantly impact future climate financing agreements for developing nations.
