We are already at the point where one or two good Volcanic eruptions are going to send us into more colder extremes.

Well, there has been seismic activity at Campi Flegrei and Yellowstone.

I think those 2 popping off would juuuuuuust about do it.

Yup. And most of the United States with it.

Actually just one of either of those would do us all in! It wouldn’t even take that much, just a couple minor eruptions fairly close together in timescale to reduce the solar insolation substantially. This is what caused the Mini-iceage as you know.

We were lucky the Mini-iceage came during a warming cycle of the current long term interglacial period. But that warm period is now over and it would not fair as well if it happened now.
