Wally Broecker is a bit of a legend – an oceanographer and thinker who has been at the forefront of climate science since the 1970s. According to Spencer Weart’s magnificent ‘history of climate science’ work…
In 1980, the prominent geophysicist Wallace Broecker, who had spoken out repeatedly about the dangers of climate change, vented his frustration in a letter to a Senator.

That clip was based on a Senate hearing that was the result of leg work done by Rafe Pomerance. See Daniel Yergin’s book, as fact-checked here.
Rafe Pomerance, president of the environmental group Friends of the Earth, was reading an environmental study when one sentence caught his eye: increasing coal use could warm the earth. “This can’t be true,” Pomerance thought. He started researching the subjective, and he soon caught with a scientist named Gordon MacDonald, who had been a member of Richard Nixon’s Council on Environmental Quality. After a two-hour discussion with MacDonald, Pomerance said, “If I set up briefings around town, will you do them?” MacDonald agreed. […]
