...how you get a lush forest if the ice caps were still there so it obviously was quite a bit hotter then.

Or it wasn't a pole, then.

Yeah - pretty sure those fossils are from when Antarctica was farther north, or maybe even when it was part of one of those super continents.

I was at a talk where the gal from NASA was talking about the south pole looking for meteorites. Due to the sublimation (evaporation) of the ice it concentrates the meteorites. She made a joke like “So - GO global warming! Yay!!” (Of course she also had the photo of the thermometer when she was there in the summer, showing -40 degrees or something.

So of course global warming isn’t causing higher temperatures that will cause the ice to melt.

Antarctica was in the same position in the Cretaceous it is now--at the pole.
