What Big Oil knew about climate change in 1959

"The next year, Exxon completed a comprehensive, 40-page internal report on climate change, which predicted almost exactly the amount of global warming we’ve seen, as well as sea level rise, drought and more. According to the front page of the report, it was "given wide circulation to Exxon management" but was "not to be distributed externally."

And Exxon did keep it secret: We know of the report’s existence only because investigative journalists at Inside Climate News uncovered it in 2015."

"In 1986, Dutch oil company Shell finished an internal report nearly 100 pages long, predicting that global warming from fossil fuels would cause changes that would be "the greatest in recorded history," including "destructive floods," abandonment of entire countries and even forced migration around the world. That report was stamped "CONFIDENTIAL" and only brought to light in 2018 by Jelmer Mommers, a Dutch journalist."

Back in 1979, Exxon had privately studied options for avoiding global warming. It found that with immediate action, if the industry moved away from fossil fuels and instead focused on renewable energy, fossil fuel pollution could start to decline in the 1990s and a major climate crisis could be avoided.

But the industry didn’t pursue that path. Instead, colleagues and I recently found that in the late 1980s, Exxon and other oil companies coordinated a global effort to dispute climate science, block fossil fuel controls and keep their products flowing.

We know about it through internal documents and the words of industry insiders, who are beginning to share what they saw with the public. We also know that in 1989, the fossil fuel industry created something called the Global Climate Coalition — but it wasn’t an environmental group as the name suggests; instead, it worked to sow doubt about climate change and lobbied lawmakers to block clean energy legislation and climate treaties throughout the 1990s.
