Actually, that's part of the evidence for global warming. If it wasn't for that the ice *would* have been advancing.

But the Yellowstone Impact would flip that quick.

The way I envision the eruption going, the ashfall on the Us would be somewhat lessened, but at the cost of more ash into the upper atmosphere where it could circle the globe.

so more or less "nuclear winter" type effects, without the radiation. There'd be more than just A "year without a summer" (cf 1815).

Not a good time for humans or anything else that depends on sunlight. (The deep ocean vent" ecosystems wouldn't even notice.)

Still better than one disaster that was discussed on rec.arts.sf.science many years back.

The idea was sparked by the bit in "Have space Suit, Will Travel" where the Three Galaxies were deciding whether or not to "rotate" Earth.

That is, displace it thru the 4th dimension to some other space-time. As noted, it would be *just* the planet, not the Sun or moon.

Great fun figuring out how fast things would freeze and what could be done to get a viable population to survive.
