How Antarctica Froze Over

Antarctica, once lush and warm, is now a frozen continent due to tectonic shifts, ocean currents, and CO2 fluctuations. The Antarctic Circumpolar Current and global cooling led to ice sheet formation. Plankton played a role in carbon sequestration, contributing to the climate shift. The ice sheets' high albedo created a positive feedback loop, further cooling the region.
