I recently watched a really good IMax movie, "Dinosaurs of Antarctica". I thought it was fascinating because I always had misunderstood the reasons for lush forests in Antarctica - I thought it was just because of plate tectonics (Antarctica was just in a more northern latitude before), but that's not the case in this instance - it really was a lush forest at the south pole. Which to me is even a bit more nuts because even though it was a lush forest it was still dark ~6 months of the year.
Climate change is coming, and it's probably going to be coming faster than it ever has in Earth's history.
- Archelaos 3y ago> it was still dark ~6 months of the year. But note that this is only true for the part of Antarctica near the South Pole. As Antarctica is quite large, there are still parts that lie even today just north of the Arctic Circle.[1] Between the Antarctic Circle and the South Pole the length of the polar night gratually increases.[2] [1] https://en.wikipedia.org/wiki/Antarctic_Circle#/media/File:Antarctic_circle.svg https://en.wikipedia.org/wiki/Antarctic_Circle#/media/File:A...

- rolldat777 3y agoApologies for being pedantic: yes, change is coming, but certainly not faster than that brought on by a giant asteroid impact or major eruption. I only mention this as I feel exaggeration harms credibility.
- JoshTko 3y agoIf the change happens at a rate faster than most life on earth can adapt then the end effect is the same. Just will happen over a decade vs. over a month.
