Why Did Antarctica Freeze?
The prime suspect is a gradual reduction of CO2 in the atmosphere, combined with a ‘trigger’ time when Earth’s orbit around the sun made Antarctic summers cold enough for ice to remain frozen all year round.
What keeps Antarctica frozen?
Antarctic Circumpolar Current
The Antarctic Circumpolar Current, or ACC, is the strongest ocean current on our planet. It extends from the sea surface to the bottom of the ocean, and encircles Antarctica. It is vital for Earth’s health because it keeps Antarctica cool and frozen. It is also changing as the world’s climate warms.Nov 15, 2018
