Exxon knew that fossil fuels were influencing the climate in 1978
Recent investigations by InsideClimate and The Union of Concerned Scientists unearthed internal company documents from 1982, revealing that Exxon’s research team was performing groundbreaking climate research and very clearly understood the consequences of carbon emissions from fossil fuels on the planet. In 1978 senior scientist James Black gave a company talk where he described the “general scientific agreement” that human-produced CO2 emissions from fossil fuels were influencing the climate. Exxon doubled down on their research, and in the early 80s published several papers on climate change in scientific journals, gaining a reputation of “genuine expertise” on the subject.
