What Big Oil knew about climate change, in its own wordshttps://phys.org/news/2021-10-big-oil-knew-climate-words.html1959: "Whenever you burn conventional fuel," Teller explained, "you create carbon dioxide. … Its presence in the atmosphere causes a greenhouse effect." If the world kept using fossil fuels, the ice caps would begin to melt, raising sea levels. Eventually, "all the coastal cities would be covered,"
1965: "The substance of the report," Ikard told the industry audience, "is that there is still time to save the world's peoples from the catastrophic consequences of pollution, but time is running out." He continued that "One of the most important predictions of the report is that carbon dioxide is being added to the earth's atmosphere by the burning of coal, oil, and natural gas at such a rate that by the year 2000 the heat balance will be so modified as possibly to cause marked changes in climate."
Ikard noted that the report had found that a "nonpolluting means of powering automobiles, buses, and trucks is likely to become a national necessity."
By the late 1970s, the American Petroleum Institute had formed a secret committee called the "CO2 and Climate Task Force," which included representatives of many of the major oil companies, to privately monitor and discuss the latest developments in climate science.
In 1980, the task force invited a scientist from Stanford University, John Laurmann, to brief them on the state of climate science. Today, we have a copy of Laurmann's presentation, which warned that if fossil fuels continued to be used, global warming would be "barely noticeable" by 2005, but by the 2060s would have "globally catastrophic effects."
Exxon had a secretive research program too. In 1981, one of its managers, Roger Cohen, sent an internal memo observing that the company's long-term business plans could "produce effects which will indeed be catastrophic (at least for a substantial fraction of the earth's population)."
In 1986, the 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.
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.
1989: the fossil fuel industry created something called the Global Climate Coalition—but it wasn't an environmental group like 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.
