Understanding How Antarctica Is Melting

The video discusses Antarctica's ice sheets, focusing on the Thwaites Glacier. While the eastern ice sheet is stable, the western sheet, particularly Thwaites, is melting and contributing significantly to global sea level rise. Thwaites acts as a barrier, preventing further ice flow into the ocean. Scientists have been studying the glacier, discovering that its grounding zone is eroding, making it more susceptible to warm water. If Thwaites collapses, it could lead to a dramatic rise in sea levels, affecting coastal cities worldwide.

What have scientists discovered about the bottom of the Thwaites glacier?

What potential impact could the disintegration of Thwaites have on coastal cities?
