Episode #420 from 1:38:42

Nuclear winter

For that, I was super privileged to talk to Professor Brian Toon, who's one of the original five authors of the nuclear winter theory. That theory was published in the early 1980s. One of Professor Toon's professors was Carl Sagan, who was sort of the most famous author of the nuclear winter theory. There were all kinds of controversies about it when it came out, including the Defense Department saying it was Soviet propaganda, which it wasn't. What the nuclear winter authors conceded back in the '80s was that their modeling was just the best it could be based on what they had at the time. And so, now flash forward to where we are in 2024, and talking to Professor Toon who's been working on this issue for all these decades since, he shared with me how the climate models today with the systems we have, the computer systems, reveal that actually nuclear winter is worse.
