The good news is that Greenland is melting, but slowly Scientists prove
Greenland ice melting is accelerating, and 2012 could be a record in terms of thawing ice cap on record. Since this process plays a significant role in raising global sea level and climate change, the planet, followed closely watching dozens of groups of scientists.
Indeed, Greenland continues to melt. But as scientists have found the University of Colorado, Wyoming, and Montana, in the winter on the island of thawing is always accompanied by the freezing of the water, which did not manage to escape into the ocean and remained inside the vents in the snow and ice cover. So formed zone "prior arrangement" slightly reduces the overall melting of the Greenland and gives an opportunity not to disappear completely, and the last for an additional ten years or so.
Some sections of the Greenland ice cap have more favorable conditions for the accumulation of snow than for its thawing. There are many sites on the top of the Greenland ice cap, where the ice is converted almost all the fresh snow. At the same time as the zone of ablation (melting) is shifted to the edges, and there is a process of melting is faster and icebergs break off more often. Until recently, the balance between the melting and ice build-up was maintained thanks to the zone of accumulation. In modern conditions, especially on the basis of 2012 data, it is clear that this equilibrium is disturbed in the direction of melting and will only be able to fix it very snowy winter of the new season.
If the volume of water in the thawed zone "prior arrangement" exceeds 70 percent or more (different computer models give different figures), water can no longer be delayed and invariably adds to the ocean, raising its level. Thawing, the ice becomes more loose and dark, which increases its ability to slip from the soil and absorb more sunlight, and therefore more quickly melt. With persistence of this trend, despite the presence of areas where freezing occurs again, and accumulation zones, a few hundred or a thousand years, Greenland may completely lose its ice cap.
