Study: Exxon Mobil accurately predicted warming since 1970s

DENVER (AP) — Exxon Mobil’s scientists were remarkably accurate in their predictions about global warming, even as the company made public statements that contradicted its own scientists' conclusions, a new study says.

The study in the journal Science Thursday looked at research that Exxon funded that didn’t just confirm what climate scientists were saying, but used more than a dozen different computer models that forecast the coming warming with precision equal to or better than government and academic scientists.

This was during the same time that the oil giant publicly doubted that warming was real and dismissed climate models’ accuracy. Exxon said its understanding of climate change evolved over the years and that critics are misunderstanding its earlier research.

Scientists, governments, activists and news sites, including Inside Climate News and the Los Angeles Times, several years ago reported that “Exxon knew” about the science of climate change since about 1977 all while publicly casting doubt. What the new study does is detail how accurate Exxon funded research was. From 63% to 83% of those projections fit strict standards for accuracy and generally predicted correctly that the globe would warm about .36 degrees (.2 degrees Celsius) a decade.
