found a couple of years ago some remarks (haven't got the refs) that

" Benjamin Franklin, in 1783, first postulated that major volcanic
eruptions affect climate, after the eruption of the Laki volcano in
Iceland. Ironically, most of the ejected material from this eruption
remained in the lower parts of the atmosphere, so Franklin had the right
idea but the wrong volcano. "

That suggests that there might have been some other major eruption in
1783 (or conceivably 1782) that was responsible for an effect on climate
(should one properly talk of climate or weather, when talking about a
period of a year or so?). Does anyone know of another major eruption?
