Phoenix, Arizona.-La layer over the Arctic Ocean ice could melt completely before the end of this century due to climate change during the summer season, causing flooding in coastal communities around the world.
Jonathan Overpeck, a geologist at the University of Arizona and leader of the group of scientists who prepared the study, said that maintaining the current trend of warmer sea currents will this phenomenon, which does not happen for a million years .
"We're already seeing the melting of ice (Arctic) now and we expect it will melt more dramatic in the future, possibly before 100 years, Overpeck said.
The analysis, prepared by nearly two dozen scientists from as many universities in the United States and Canada, appeared in this week's issue of the journal EEOS , published by the American Geophysical Union.
According Overpeck, the current trend of warmer ocean currents caused by climate change is accelerating the melting of Arctic ice experts can not identify a natural process slow phenomenon.
Melting sea ice has already resulted in dramatic impacts on coastal indigenous peoples of the Arctic, including areas of the United States (Alaska), Canada, Russia, Scandinavia and Greenland. As far as temperatures rise, will melt even more glaciers and Arctic ice.
This will increase the level of sea water and cause flooding in coastal areas inhabited by large numbers of people around the world. Overpeck
ruled that the effects could be similar to the scenario presented by fatal film The Day After Tomorrow where millions of people die as a result of a new Ice Age due to climate change.
however, stressed that the melting of the Arctic ice cap will have terrible repercussions for many.
"What makes the Arctic different from other areas of the world is the permanent ice it has in the land and ocean. If that does change and ceases to recur in certain seasons of the year, would cause serious problems "he added.
