ExxonMobil Scientists Doubt Climate Fixes Hyped by the Company

In 1988, NASA climatologist James Hansen testified to Congress about climate change. Weeks before the UN established the Intergovernmental Panel on Climate Change, Exxon's Frank Sprow warned colleagues in an internal memo about potential negative impacts on the company if a consensus emerged on mitigating greenhouse gas effects. Recently released documents, part of a lawsuit, include statements from Exxon scientists challenging the company's climate-solution claims on biofuels and carbon capture and storage.
