Had a discussion with the wife about the last winter. That there will be a last winter with meaningfully cold temperatures was something that she had not considered at all.
Its complicated day to day but it's not that complicated. We have a giant heat sink in the form of the arctic ocean. Once its ice free I expect freezing temperatures to be rare. There will be a point where this area(north west north america) no longer sees the 80 degree C swings in temperature that it has seen historically. Expectation is closing the temperature gap biased high.
Yeah, no. It's much more complicated. If e.g. the gulf stream changes significantly winters in Europe might get much colder. It is not as easy as Hollywood movies portray it.
Globally we will have warmer temperatures, that much seems to be pretty much confirmed. But locally the results will vary very much.
You may have missed the point. Even if the haline circulation is over turned with fresh water, Europe will still trend warmer on a wider delta and different places will see an increase in seasonal delta but as it stands there will be a last winter for everywhere. Full stop. It is a time horizon question that remains.
It remains to be seen if global temperature will eventually max out (likely after a major population decline) or if we're headed in the direction of Venus, where the planet just gets turbo-fucked beyond the ability to retain any life.
