Arctic from the heat turned green

A perfect ice began to absorb more heat, and the tundra is covered with grass

Employees of the National Oceanic and Atmospheric Administration USA (NOAA) concluded that the Arctic climate began a new phase, according to Associated Press.
Ice, which darken in the process of melting, began to absorb more heat and solar radiation, and Tundra by increasing the temperature actively green.

Reports on the state of the Arctic published annually since 2006. They provide information about the atmosphere, ice and waters of the Arctic Ocean and the Arctic ecosystems and Greenland. This year, the report added new sections on "greenhouse gases", ultraviolet radiation, and chemical processes in marine waters. The findings suggest that adverse changes in the climate of the region, which are the result of global warming.

Since 2000, the area of ice in Greenland dropped by almost 530 square meters. miles. "Over the past five years, the thickness of ice in the Arctic Ocean was the thinnest on record. For two consecutive years, all three major Arctic Straits were free in the summer for the passage of ships", — the report says.

Apparently, the melting ice will only accelerate. Covered with snow or ice surface reflects sunlight well, but at the slightest melting appears turbid water, which absorbs the heat, at times increasing the effects of global warming.

Temperatures over the Arctic territories will increase, helping to increase the tundra vegetation, leading to changes in the lives of the inhabitants of marine and terrestrial ecosystems. Today shrinking habitat of polar bears and walruses. But there are those who benefit from warming. Over the last decade the amount of phytoplankton in the Arctic Ocean, which is the main food for whales, increased by 20%.

"We do not know for sure whether this is a turning point, or the climate to recover," — said one of the authors of the report, a geophysicist Don Perovich.
