According to an article published in “Science”, the models carried out by the oil and gas company allowed him to take the measure of global warming, while his official speech was built on the climate denial.

Exxonmobil was perfectly aware of global warming. The research carried out by the scientists recruited by the company was “solid”, and allowed it, in 1977, to take the measure of global warming caused by human activities. This is the main teaching of a article Published in Science Thursday January 12 , written by Geoffrey Supran and Naomi Oreskes, both historians of science at Harvard University, and Stefan Rahmstorf, specialist on climate modeling of the Potsdam Research Institute on Effects Climate change in Germany (Pik).
Solicited by MO12345lemonde, the American firm denies it: “Those who say that Exxon knew are wrong in their conclusions, reacted Thursday Todd Spitler, media relations advisor at Exxonmobil. Some have sought to distort the facts and Exxonmobil’s position on climate science. “However, the petrogazière company has been the subject of many public hearings in the US Congress and the European Parliament because of its denial of climate change in recent years.
Exxonmobil scientists had precisely planned global warming due to the combustion of fossil fuels and had dismissed the possibility of the next glacial period, theory yet regularly used in the speeches of the company with the general public. They had thus evaluated that warming would be around 0.20 degree Celsius per decade and correctly estimated the carbon budget in the case of a warming scenario limited to 2 ° C.
“model used by Scientists “
In 2017, the two historians, reflected in particular by journalistic surveys on the double climate discourse of the Exxonmobil group, had guided their research on the analysis of the texts produced by the scientists of the American firm. Three years later, they immersed themselves in climate modeling projections of the Pétrogazière company, a material rarely examined. “This situation contrasts with university climate models, the performances of which have been largely examined,” report the authors in the article.
They therefore plunged into 104 scientific documents of the company, dating from 1977 to 2003, including 72 scientific publications, written or co -wrote by “house” scientists and peers. “Exxon has made a particular effort to integrate his scientists into the dominant current of university research so that they can have direct access to the cutting -edge knowledge of the community, and thus have a better vision of the crisis that their products were going to cause “, Geoffrey supran analysis.
