In the 1980s, oil companies like Exxon and Shell carried out internal assessments of the carbon dioxide released by fossil fuels, and forecast the planetary consequences of these emissions. In 1982, for example, Exxon predicted that by about 2060, CO2 levels would reach around 560 parts per million – double the preindustrial level – and that this would push the planet’s average temperatures up by about 2°C over then-current levels (and even more compared to pre-industrial levels).

Later that decade, in 1988, an internal report by Shell projected similar effects but also found that CO2 could double even earlier, by 2030. Privately, these companies did not dispute the links between their products, global warming, and ecological calamity. On the contrary, their research confirmed the connections.

Shell’s assessment foresaw a one-meter sea-level rise, and noted that warming could also fuel disintegration of the West Antarctic Ice Sheet, resulting in a worldwide rise in sea level of “five to six meters.” That would be enough to inundate entire low-lying countries.

For its part, Exxon warned of “potentially catastrophic events that must be considered.” Like Shell’s experts, Exxon’s scientists predicted devastating sea-level rise, and warned that the American Midwest and other parts of the world could become desert-like. Looking on the bright side, the company expressed its confidence that “this problem is not as significant to mankind as a nuclear holocaust or world famine.”

The documents make for frightening reading. And the effect is all the more chilling in view of the oil giants’ refusal to warn the public about the damage that their own researchers predicted. Shell’s report, marked “confidential,” was first disclosed by a Dutch news organization earlier this year. Exxon’s study was not intended for external distribution, either; it was leaked in 2015.

Nor did the companies ever take responsibility for their products. In Shell’s study, the firm argued that the “main burden” of addressing climate change rests not with the energy industry, but with governments and consumers. That argument might have made sense if oil executives, including those from Exxon and Shell, had not later lied about climate change and actively prevented governments from enacting clean-energy policies.

Despite scientific uncertainties, the bottom line was this: oil firms recognized that their products added CO2 to the atmosphere, understood that this would lead to warming, and calculated the likely consequences. And then they chose to accept those risks on our behalf, at our expense, and without our knowledge.
