Sea level rise overflowing estimates

Feedback mechanisms are speeding up ice melt

Sea levels may swell much higher than previously predicted, thanks to feedback mechanisms that are speeding up ice melt in Greenland and Antarctica.

Global warming feedbacks are speeding up the rise of sea level, which is expected to rise 1 meter by 2100. If the East and West Antarctic ice sheets melted, waters would rise by about 80 meters, submerging Florida and the Gulf Coast.
