Greenland is less vulnerable than expected to a runaway melt that would drive up world sea levels, according to scientists who found that only a quarter of the ice sheet thawed in a warm period mor

London: Rise in sea levels in the future due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than IPCC estimates, according to a new first-of-its-kind study. Researchers from the University of Bristol found that the future rise in sea levels predicted by the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) may be even greater.

The ice sheets covering Antarctica and Greenland contain about 99.5% of Earth’s glacial ice which would raise global sea level by some 63m if they were to melt completely.

NEW DELHI: The combined rate of melting for the ice sheets covering Greenland and Antarctica has increased during the last 20 years says a landmark study published Thursday in the journal Science.
