I recently ran across this story from January 2018 which describes an invited talk that Edward Geller, famous physicist and part of the Manhattan Project, gave to a gala celebration noting the 100th anniversary of the petroleum industry. According to a transcript of the speech, given in 1959, Geller warned petroleum executives that the increase in carbon dioxide in the atmosphere would inevitably lead to warming and that they should prepare for a move to other sources of energy as petroleum and coal supplies dwindle. Another example of how knowledge of warming due to greenhouse gases is not new, but was well established decades or even centuries ago. You can read the story here.
