In 1982, ExxonMobil Scientists Predicted Carbon Dioxide Would Reach 410-420 ppm by 2020; Read the Internal Report

Informed Comment reports that internal ExxonMobil documents show that the company’s scientists predicted in 1982 that by 2020, parts per million of carbon dioxide in earth’s atmosphere would reach 410-420 ppm. For the first time this spring ppm of CO2 exceeded 415.

The memo says in part,

“Considerable uncertainty also surrounds the possible impact on society of such a warming trend, should it occur. At the low end of the predicted temperature range there could be some impact on agricultural growth and rainfall patterns which could be beneficial in some regions and detrimental in others.

“At the high end, some scientists suggest there could be considerable adverse impact including the flooding of some coastal land masses as a result of a rise in sea level due to melting of the Antarctic ice sheet.”
