Studies conducted by NASA using one of the satellites, indicate the existence of a disappointing trend, says New Scientist. Over the past twenty years, the rate of temperature increase in the Arctic has increased eightfold.
"The climate is changing, and the most noticeable of these changes will be in the polar regions, — says David Rind, a specialist of one of the institutions of NASA. — There soon and will be the main study."
Satellite data show that the area of ice cover in 2002 was the smallest in the twenty years during which there is a satellite monitoring of the Arctic ice cap. The average summer temperature of the ice cover over the last ten years has increased by 1.22 degrees. The higher the temperature, the thinner becomes ice. In the North American continent from coast-risk flood areas have relocated some of the villages.
Further events may develop an avalanche. The melting of the ice increases the water's surface, as a result of land reflects into space less solar enegrii and more heat, which contributes to further melting of the ice. The increase in the surface area of the sea contributes to the emergence of stronger winds. Because of them, the sea formed the higher the waves are stronger than erode the remaining ice.
