Exxon’s Own Research Confirmed the Role of Fossil Fuels in Global Warming Decades Ago

Oil giant Exxon conducted cutting-edge climate research in the 1970s, and then, without disclosing the findings of its scientists, worked to manufacture doubt about the scientific consensus of its own research.

A groundbreaking investigation shows how the company’s top executives were warned of possible catastrophe from global warming, then led efforts to block solutions.

InsideClimate News explains:

At a meeting in Exxon Corporation’s headquarters, a senior company scientist named James F. Black addressed an audience of powerful oilmen. Speaking without a text as he flipped through detailed slides, Black delivered a sobering message: carbon dioxide from the world’s use of fossil fuels would warm the planet and could eventually endanger humanity.

“In the first place, there is general scientific agreement that the most likely manner in which mankind is influencing the global climate is through carbon dioxide release from the burning of fossil fuels,” Black told Exxon’s Management Committee, according to a written version he recorded later.

It was July 1977 when Exxon’s leaders received this blunt assessment, well before most of the world had heard of the looming climate crisis.

A year later, Black, a top technical expert in Exxon’s Research & Engineering division, took an updated version of his presentation to a broader audience. He warned Exxon scientists and managers that independent researchers estimated a doubling of the carbon dioxide (CO2) concentration in the atmosphere would increase average global temperatures by 2 to 3 degrees Celsius (4 to 5 degrees Fahrenheit), and as much as 10 degrees Celsius (18 degrees Fahrenheit) at the poles.  Rainfall might get heavier in some regions, and other places might turn to desert.

“Some countries would benefit but others would have their agricultural output reduced or destroyed,” Black said, in the written summary of his 1978 talk.
