Atmospheric carbon dioxide sets a new record every year. This year’s cracked the ominous milestone of 415 parts per million (ppm) thanks to ever rising emissions from human activities. The sharp rise might seem like something nobody could’ve predicted but there’s at least one group of scientists that were on the money 37 years ago: Exxon’s ace team of scientists.

Bloomberg reporter Tom Randall revisited the memos in light of the world’s new carbon dioxide milestone and tweeted a graph from one showing just how much Exxon knew what our future would look like.
