‘Greenland ice sheet melting faster than thought’

Greenland’s ice sheet may have completely melted within the next millennium if greenhouse gas emissions continue at their current rate, according to a new study with implications for sea-level rise around the world, reports AFP.

The Greenland ice sheet holds the equivalent of seven meters (yards) of sea level. “If we continue as usual, Greenland will melt,” said lead author Andy Aschwanden, a research associate professor at the University of Alaska Fairbanks’ Geophysical Institute. It is the most recent warning about warming in the world’s coldest regions.     

“What we are doing right now in terms of emissions, in the very near future, will have a big long-term impact on the Greenland ice sheet, and by extension, if it melts, to sea level and human society,” Aschwanden said.

The study, which used data from NASA’s Operation IceBridge airborne campaign and was published in Science Advances, is the latest to suggest a much greater rate of melt than was estimated by older models.
