Is this the same volcano that erupted back in the 70s and caused us to have such cold, wet winters in the late 70s/early 80s?
I’m not sure - what little info. I found suggests more of a regional effect, with no reference to a particular volcano. Alaska, for example, was unusually warm, in the winter of 1976-77, while the central and eastern US shivered.
