As Greenland ice melts, Greenland itself rises

SHOOT: Could this be triggering Iceland's present volcanism? On a global scale changing ocean levels could cause new stresses on terrestrial strata, causing an uptick in worldwide volcanic and earthquake activity. Yet another unforeseen consequence of anthropomorphic global warming/climate change.

The ice is melting so fast in Greenland that the giant island is
rising noticeably as the weight is lifted. In some spots, the land is
rising 1 inch per year.

A vast ice cap covers much of Greenland,
in some places up to 1.2 miles (2 km) thick. The ice, in place for
eons, presses down the land, making the elevation at any given point
lower than it would be sans ice.

Scientists have documented on Greenland and elsewhere that when longstanding ice melts away, the land rebounds. Even the European Alps are rising as glaciers melt.

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.

"It's been known for several years that climate change is
contributing to the melting of Greenland's ice sheet," Dixon said in a
statement. "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."
