Antarctica froze over when the planet was averaging at least 4C
warmer and CO2 was at least 800ppm. That's when it froze over.
And it didn't freeze over BECAUSE it was so hot or BECAUSE there
was so much CO2. It froze over because the Circumpolar Current
formed, effectively walling it off from warmer waters circulating
from the equator. Which means, and you need to take notes here,
the only way to warm up Antarctica is to STOP the circumpolar
current.
Oh. And you can alter the tilt of the earth so that Antarctica
is getting more direct sunlight. But the earth has been wobbling
all along, and tilting on it's access all along so why would it
suddenly change things THAT dramatically now?
Oops. Gwobull Warbling isn't science, it's a scam.
