This feature by Newsclick illustrates the instability of the Antarctic ice sheet, with six of its glaciers melting and flowing into the Amundsen sea. It is expected that over the next 100 years the sea level could rise by about 3 feet, putting several low lying areas in the world including parts of India, under water. Clearly global warming is the larger cause but this is also caused by warm ocean water melting the glaciers from below. The feature reasons as to why the glaciers are melting faster than predicted. It also points out that the rate of this retreat could accelerate in the future, leading to an even bigger disaster.
