Greenland Melting Produces New Islands

Greenland

The rapid melting of Greenland’s ice sheet is causing new islands to spring up all over. The map makers cant seem to keep up with the change in the coastline. Ironic that the melting of Greenland is causing more islands to form while elsewhere the melting of Greenland (and other places) are causing islands to disappear.

Maps of the region show a mountainous peninsula covered with glaciers. The island’s distinct shape — like a hand with three bony fingers pointing north — looks like the end of the peninsula.

Now, where the maps showed only ice, a band of fast-flowing seawater ran between a newly exposed shoreline and the aquamarine-blue walls of a retreating ice shelf. The water was littered with dozens of icebergs, some as large as half an acre; every hour or so, several more tons of ice fractured off the shelf with a thunderous crack and an earth-shaking rumble.

All over Greenland and the Arctic, rising temperatures are not simply melting ice; they are changing the very geography of coastlines. Nunataks — “lonely mountains” in Inuit — that were encased in the margins of Greenland’s ice sheet are being freed of their age-old bonds, exposing a new chain of islands, and a new opportunity for Arctic explorers to write their names on the landscape.

“We are already in a new era of geography,” said the Arctic explorer Will Steger. “This phenomenon — of an island all of a sudden appearing out of nowhere and the ice melting around it — is a real common phenomenon now.”

In August, Mr. Steger discovered his own new island off the coast of the Norwegian island of Svalbard, high in the polar basin. Glaciers that had surrounded it when his ship passed through only two years earlier were gone this year, leaving only a small island alone in the open ocean.

“We saw it ourselves up there, just how fast the ice is going,” he said.

With 27,555 miles of coastline and thousands of fjords, inlets, bays and straits, Greenland has always been hard to map. Now its geography is becoming obsolete almost as soon as new maps are created.
