Melting sea ice has accelerated warming in the Arctic, which in recent decades has warmed twice as quickly as the global average, according to a new study.

As it melts, sea levels around it will fall, say Natalya Gomez and Jerry Mitrovica of Harvard University and colleagues: with the mass of ice shrinking, its gravitational pull on the seawater will be weaker.

As the melting of the Arctic sea ice accelerates, countries with claims on Arctic Circle territory — including not just Russia and Canada but also the United States, Denmark, Norway, Sweden, Iceland, and Finland — are scrambling to send mapping expeditions to the icy North.

Alaskan and the Canadian Arctic land - based glacier melt ranks with that of the Greenland Ice Sheet as important contributors to global sea - level rise that is already underway.

Greenland and Antarctica's massive ice sheets exert a strong gravitational pull on the waters around them, but as they melt, the attraction weakens, causing nearby sea levels to fall.

Glaciers around the world are melting and contributing to sea level rise, but scientists still don't quite understand how exactly glaciers give birth to icebergs as they flow into the ocean and lose ice.

All told, if the eastern and western Antarctic ice shelves were to melt completely, they would raise sea levels by as much as 230 feet (70 meters); the collapse of smaller shelves like Larsen B has sped up the flow of glaciers behind them into the sea, contributing to the creeping up of high tide levels around the world.
