In jest, friend.

I think the only realistic one is to spread aerosols into the stratosphere. It would certainly work and is probably doable. The problem is if the Earth was about to do some natural cooling anyway it could go too far. Either that or a Tabora type eruption happened right afterward. Backfire potential would be high.

Is waiting until later in January really such a catastrophic outcome?

I just don’t see how doing that on a meaningful scale is feasible. And wouldn’t pumping warm water on top of the ice across the Arctic possibly even warm the surface temps across the north.

This still would not have resulted in any memorable lowland snow events this winter, thus far.
