How Big Is Thwaites Glacier?

Called the Thwaites Glacier, it is 120 km wide at its broadest, fast-moving, and melting fast over the years. Because of its size (1.9 lakh square km), it contains enough water to raise the world sea level by more than half a metre.

How thick is the Thwaites Glacier?

Because Thwaites is so vast, the measurements were confined to a region known as its eastern ice shelf, where a floating part of the glacier is 600 meters (nearly 2,000 feet thick) and underlain by just 40 meters (about 130 feet) of water.

How tall is the Thwaites Glacier?

The cavity formed mostly in the previous three years and is nearly a thousand feet tall, likely speeding up the glacier's decay. Thwaites currently contributes roughly 4% to global sea level rise.
