Probably not the size of Pinatubo either which reduced temperatures by a few tenths of a degree C. Pinatubo ejected a fairly large quantity of material for a number of blasts. I think the difference with Taal might be duration but it still might not reach as high in the stratosphere. The Little Ice Age peaked just before the Taal 1754 eruption and I don't see evidence of cooling from that eruption.
So unless it does something different I don't see it impacting the weather.
Depends on the magma it spews. And the type of explosion.
But the past eruptions all point to a local event. Nobody knows.
First thing ya know, ya dont know nothing. LOL.
