EARTH DAY for GLOBALWARMING

The researchers predicted, the Arctic Sea (poles) will be free of ice in summer within the next decade. After the spring over, the researchers re-measured the thickness of the ice along the 450 mile route across the Beaufort Sea. They found most of the ice is very thin.

Expedition leader and a sea ice expert from the University of Cambridge, Peter Wadhams, said in the spring of last year's average ice thickness is only 1.8 meters, indicating the age of the layer was about one year. Meanwhile, the ice that had for years about 3 meters.

Thin layer becomes important indications concerning the condition of ice in the Arctic Sea. "Simply put, the thin ice will disappear in an instant ice began to melt season," he said. Wind and ocean currents could also break the thin ice. Broken ice floating freely and be easily driven into the area warmer waters and melt. Catlin Arctic Survey and the international conservation group WWF supports these findings.

The situation in the Arctic ice is very influenced climate and natural conditions. Sea ice conditions in the Arctic is often also associated with climate change and global warming.
