What caused the other warming periods that happened in the last 4,000 years? Sea levels have risen 40 feet in that time, averaging a foot every 100 years.
Or the last 11,000? Ice has been melting for that long globally. Its not a new thing. When should it have stopped?
It actually did reverse for a time, then peak ice of the last 1000 years was around 1570 ish. Why did it stop expanding then and reverse?
Should the planet be cooling right now if it weren’t for humans? Or is there a perfect static temperature we should expect?
If we don’t think about these things, we may draw a wrong conclusion.
Asking for a friend.
