Berlin, 9 sep (EFE).-the layer of ice covering the Arctic Ocean has registered this summer a new and disturbing record of thawing until reduced to an area of 4.24 million kilometers square.
A spokesman for the Institute of environmental physics, University of Bremen announced today that this has surpassed brand of 2007, year in which the ice surface had recorded elevations lower with 4,267 million kilometers square.
“The surface ice in summer has reduced since 1972 by 50 percent”, said Georg Heygster, scientific cited Institute of the Hanseatic City, which attributed the thawing to the effects of climate change.
Also warned that “living beings that occupy the ecosystem under the ice sheet and which are the starting point of the food chain also for us, humans, have increasingly less living space”.
Heygster explained that the ice of the Arctic Ocean surface oscillates normally between 15 million square kilometres in March and 5 million in September.
After explaining that the new record this summer thawing outnumber a 0.6 per cent in 2007, commented that the reduction of the ice surface could increase even more before the end of this month.
German scientist also confirmed this summer opened as a result of thawing of the Arctic Northeast maritime route off the northern coast of Russia as the Northwest bordering Canada, phenomenon that had already occurred in 2008.
Finally, pointed out that the retreat of the ice surface of the Arctic already cannot be explained by natural variability that occurs from year to year, but by climate change, and warned that the central ice cap lost also thick. EFE
