I host “The Precipice” reading groups for EA Virtual. One participant asked how nuclear winter models have evolved such that nuclear winter is now predicted to be much longer. Ord states that nuclear winter models have changed significantly from the original, though the basic mechanism is the same. He stated that the details were to conplex too go into in the book. Could someone give me a source or explain how exactly nuclear winter models have evolved to be more complex and predict longer nuclear winter?
Edit: this is not a question about how a nuclear war would play out, it is specifically about the mechanism of how nuclear winter would occur, which Ord states has evolved away from and become more complex than smoke blocking out the sun, though in essence it is similar.
