Underwater dams can stop thawing of glaciers


Scientists suggest to build of Princeton University to both Antarctica and the Arctic huge underwater walls. According to them, it can be the most effective - and, strangely enough, in the cheapest way to slow down thawing of ices against the background of global warming, Live Science writes.

Because of global warming global sea level for quarter of the century has grown on and 77,1 millimeters (by 3,1 millimeters a year). Since 1993 the average global gain of global sea level makes 3,1 millimeters (from 2,8 to 3,4 millimeters). The major role in it is played by thermal expansion of water, on the second place - thawing of glaciers of Greenland and Antarctica.

Is a disturbing tendency as because of further increase in water level the island states can be waterlogged. According to the report of the World Bank, the state of Fiji it is necessary to spend in $4,5 billion within 10 years to minimize damage from increase in water level.

because of temperature increase polar ices have begun to thaw and collapse Recently gradually. Worst of all, when warm water destroys the basis of a glacier and it begins to float in the ocean as a small piece of ice in a glass. By words John Moura from the University of Lapland, such freely floating ice melts even quicker, than static.

to resist to this tendency, authors offer two options of artificial glaciers: an underwater wall which will isolate warm water from the glacier basis, or system from small hills which will stop freely floating icebergs.

was reported Earlier that the oldest and strong glacier in the north of Greenland which scientists considered firm has begun to collapse. Besides, researchers from Yale University and Woods-Holdsky oceanographic institute warn that the large reserves of warm water disappearing under glaciers of the Arctic gradually rise to a surface. It can provoke thawing of ices and accelerate increase in global sea level. 154
