But if they do, guess what, it’s another negative feedback mechanism omitted from all the climate models, since, as we know from experience, volcanic eruptions cool the earth by disbursing ash into the upper atmosphere (cf. Tambura and the ‘year without a summer’ in 1816).
I’m starting to think climate modeling should be turned over to Shakespeare scholars: “There are more things in heaven and earth than are dreamt of in your philosophy. . .”
