Greenland's ice sheet melting seven times faster than in 1990s

Greenland's ice sheet melting seven times faster 

Greenland’s ice sheet is melting much faster than previously thought, threatening hundreds of millions of people with inundation and bringing some of the irreversible impacts of the climate emergency much closer.

 since the 1990s it is now shedding more than seven times as much ice each year, according to 89 scientists who use satellites to study the area.

"Around the planet, just 1 centimeter of sea-level rise brings another 6 million people into seasonal, annual floods," said Andrew Shepherd, a University of Leeds professor who co-led the massive collaboration with NASA researcher Erik Ivins.

The research suggests an alarming pace of change for the Earth's second-largest body of ice, which could theoretically drive more than 20 feet (6 meters) of sea-level rise over a millennium.

Several large glaciers account for the biggest ice losses — with Jakobshavn Glacier, in central Greenland, leading the way.
