Investigation Finds Exxon Ignored Its Own Early Climate Change Warnings

New submitter jrmcferren writes: PBS Reports the Exxon ignored their own internal climate change warnings. Newly discovered documents show that the corporation's own research scientists warned top executives that atmospheric CO2 was increasing and that the burning of fossil fuels was to blame as early as 1977. The report goes on to say: "In 1978, the Exxon researchers warned that a doubling of CO2 levels in the atmosphere would increase average global temperatures by 2 to 3 degrees Celsius and would have a major impact on the company’s core business. 'Present thinking holds that man has a time window of five to ten years before the need for hard decisions regarding changes in energy strategies might become critical,' one scientist wrote in an internal document."
