In the melting of the Arctic polar ice blame fires Scientists prove
With the help of satellites, scientists have traced the movement of smoke and soot produced during the polar tundra fires in the northern hemisphere and have concluded that accumulated on the ice cover of the soot particles are greatly contributed to accelerated melting of the Greenland ice last summer.
Certainly, intervened to discuss events and clear weather over Greenland, and warm coastal ocean waters. But the appearance of soot factor also played a role. We all know how dark soot from dirty snow and ice are losing their ability to reflect solar heat and begin to melt more quickly, that as the ice crystals lose their edge and become spherical.
In abnormally rapid melting of ice from July 2011 almost the entire length of Greenland to blame and fire caused directly on the island and along the Labrador Straits. It is noteworthy that the peak of this process occurred in four specific days — from 8 to 12 July 2011 — when the percentage of ice fell from 40 to 97 and. a little earlier, it was found that the reflectance of Greenland decreased by 7% over the last decade. Soot and ash in the near future can significantly increase this percentage.
This trend can only increase as the warmer the climate, the greater the risk of fire in the tundra, where every warmest year there are more vegetation. This, in turn, will lead to an increase in the icy expanses covered with soot.
