Greenland rapidly rising as icecap melt continues
Greenland is situated in the Atlantic Ocean to the northeast of Canada. It has stunning fjords on its rocky coast formed by moving glaciers, and a dense icecap up to 2 km thick that covers much of the island–pressing down the land beneath and lowering its elevation. Now, scientists at the University of Miami say Greenland’s ice is melting so quickly that the land underneath is rising at an accelerated pace.
According to the study, some coastal areas are going up by nearly one inch per year and if current trends continue, that number could accelerate to as much as two inches per year by 2025, explains Tim Dixon…principal investigator of the study.
“It’s been known for several years that climate change is contributing to the melting of Greenland’s ice sheet,” Dixon says. “What’s surprising, and a bit worrisome, is that the ice is melting so fast that we can actually see the land uplift in response,” he says. “Even more surprising, the rise seems to be accelerating, implying that melting is accelerating…”
“During ice ages and in times of ice accumulation, the ice suppresses the land,” Shimon Wdowinski says. “When the ice melts, the land rebounds upwards,” he says. “Our study is consistent with a number of global warming indicators, confirming that ice melt and sea level rise are real and becoming significant…”
One of the study investigators, Yan Jiang says, “We hope that our work reaches the general public and that this information is considered by policy makers.”
