A new study by academics reveals the oil giant Exxon had funded research in the 1970s that accurately predicted global warming that the company downplayed in public.

The Harvard and University of Potsdam academics study found that Exxon scientists’ projections about climate change and global warming were between 63% to 83% accurate.

Findings
Exxon researchers warned that the Earth would warm at the rate of 0.20°C per decade through the 1970s to early 2000s. They even knew how much carbon dioxide needs to be emitted for the world to warm by more than 2°C.

Some of Exxon's research findings on human-caused global warming were more accurate than NASA’s projections in 1988.

Still,
The recent study says that the oil corporation Exxon accepted and discussed its research internally, but brushed aside global warming predictions as inaccurate information when confronting the public and its investors.
