Worse than you can imagine! About such a phrase could utter scientists, analyzing the state of Greenland and Arctic ice. Nearly 20-year study, funded by NASA, says that mankind should prepare for the worst — the glaciers are melting faster and faster, and the rate of melting increases at a rate that could not predict the scientists in their most pessimistic forecasts.
It was found that the annual ice lost in the mass of 36.3 gigatons (unit of mass equal to 10 to the ninth power tons) more than the previous year. To give an idea of the scale of the annual loss of ice, researchers give the following example. Only one 2006 Greenland and Arctic ice lost a total of 475 gigatons of its mass. Previously, experts believed that this figure does not exceed 402 gigatonnes, and this year will accelerate the melting of at least three times lower.
"Even the predictions that were considered alarmist and very pessimistic, now were" beaten "- the situation is even more dismal than expected — says the representative of" Greenpeace Russia "Igor Podgorny. — Those glaciers, which, according to experts, should have been a thief for many months and years melt away within a week. That is what is the scope and rate of melting. "
There is a process, not only the melting of the glacier, but the destruction, which makes the situation even more harmful to humanity. Right now, most researchers agree that in 2100, global sea level rise is guaranteed for at least 1 m will thus be flooded many island nations, which are, say, in Oceania. May disappear and the Maldives. Now, however, experts believe that sea levels can rise even more than 1 m, with the next century.
There is a view that global warming is causing the rapid melting of Arctic ice will not only open access to previously inaccessible natural resources, but also pave the way for new shipping. However, this is far from certain point of view. Not least because the number of icebergs that stand in the way of the Northern Sea Route, will increase.
"In addition, when the ice is melting, changing the reflectivity of the areas — the so-called albedo. The Arctic is becoming more dark surfaces than white ice, which quietly reflect sunlight into the atmosphere. Accordingly, the dark surface will absorb them — warns the representative of "Greenpeace". — Where are we? It will be even warmer, ice will melt faster, climate change will occur more rapidly. "
