Greenland's melting ice, which causes a rise in sea levels, has disappeared four times faster in 2013 than in 2003 and is seen on the Arctic island, not just glacier, researchers said yesterday.

"Although 111 cubic kilometers of ice disappeared in 2003, 10 years later, this figure has almost tripled to 428 cubic kilometers," the Spatial Laboratory of the Danish Technical University (DTU) said in a statement.

His researchers contributed to the study of the changes on the Greenland iceberg, published in the American Journal Proceedings of the National Academy of Sciences (PNAS).

"These are the remarkable changes we see in the ice melting model," said Professor DTU Shfakat Abbas Khan.

So far, most of the ice cannons in Greenland have been spotted on an ice cap, predominantly on glaciers in the northwest and southeast of the island.

But most of the loss of ice from 2003 to 2013 was from the southwestern region of Greenland, which is mostly without large glaciers.

Michael Bevis, a professor at Ohio State University and lead author of the PNAS paper, said the ice is now melting from the surface mass, "melting into the interior of the shore."

This means that in the southwestern part of Greenland, the rising waters of the river are poured into the ocean.

"We knew we had one big problem with increasing the rate of discharge of ice by some big glaciers at the exit," said Bevis.

"But now we recognize another serious problem: more and more, massive amounts of ice will go as melted waters, like rivers that fly into the sea."

He warned that this would have great implications, causing an additional rise in the sea.

"We are watching the ice ball hit the spot," he said, condemning the whole huge ice block to melt over a span of several hundred or several thousand years.

Greenland ice cover – up to three kilometers – contains enough frozen waters to lift the global sea level at about six feet.

The ice spot observed in the study was caused by an increase in soil temperature, and partly by the fact that the ice comes into contact with increasingly warmer waters.

"As the temperature of the atmosphere gradually increases, we will immediately notice the acceleration of ice melting," Khan said.

Although the number varies from region to region, sea levels have risen in the world by an average of 20 centimeters in the 20th century. They are currently increasing by about 3.3 millimeters per year. – AFP
