Large-scale conference on the colossal Arctic changes

April 19.2,000 scientists are expected at the conference on the Arctic in Montreal

It took hundreds of scientists from dozens of countries with million budget to make one simple conclusion.

People living in the Arctic and the government, which controls it, not keeping pace with the changes proiskhodyamischi there under the influence of climatic shifts.

"I work in the Arctic for 30 years and I am amazed the speed with which everything is changing in the Arctic," — said David Barber, an expert on glaciers at the University of Manitoba, who will perform in Montreal at a conference on Arctic research next week.

"It's incredibly impressive."

More than 2,000 scientists are expected to meet weekly to discuss the results of the studies for the International Polar Year (IHL), which lasted from 2007 to 2009.

Research required the efforts of scientists from 60 countries and the financing of 1.2 billion U.S. dollars. The result was hundreds of scientific publications.

Changes such as the shrinking of Arctic ice have since become widely known, in contrast to this the fact that the rate of change is growing.

"The changes are so rapid that regulatory environment — in particular on the problems of navigation and security — simply can not keep up with them, not only physically, but also in economic terms," — said Lawson Brigham, a professor of geography and Arctic policy at the University of Alaska .

On a small country Brigham natives living along the coast, were driven out increasing rate of destruction of coastline.

"We are faced with relocation of several communities inland, so they can live normally."

Summer ice pack under threat

Changes throughout.

Temperature rises so quickly that Barber changed his outlook on izcheznovenii summer ice pack to the 2100 at a much earlier time — next year. (Ice pack — sea ice thickness of at least 3 meters, which lasted more than two annual cycles of growth and melting. — Approx. Ed.)

Ice breaks, the icebergs in the Beaufort Sea, where power companies were going to start the search and exploration drilling.

"Icebergs became much more and they are a far greater threat than ever before", — said Barber.

Reduction of ice as well as the winter snowpack, cause a sharp reduction in animals, such as gulls and walruses.

Navy SEALs who need snow, making dens to protect newborn calves also suffered. Populations of small rodents such as lemmings, apparently disappear.

Trees and shrubs of the boreal (arctic) forests shifted to the tundra, bringing new animals, such as the red fox, which displace endemic foxes.

Moth winter inhibits the growth of trees in the Arctic part of the Scandinavian Peninsula. Ixodes ticks winter Yukon attack plants that have not previously encountered ticks.

Northern natives, whose livelihood depends on their ability to hunt and fish, were in a difficult situation when the situation suddenly changed.

Traditional methods of hunting, hunters are taught to adapt, less often passed down from generation to generation.

"The fact that the natives cut off from the land and food supplies, causing problems in the heart of northern communities," — says Tristan Pearce of the University of Guelph.

"People get stuck in one place or simply avoid traveling, — he says. — Livelihoods are paramount to the health and prosperity of the community. "

Meanwhile, the rising prices of consumer goods and better access increased the demand for Arctic resources — from oil fields to fish.

And while countries with Arctic territories may monitor activity on their coastal waters, central Arctic Ocean — who had once been forbidden bezlyudnoy ground, covered with ice all year — has become a global and largely uncontrolled by any common fund.

"The whole Arctic region is rapidly becoming part of the global economy", — said Brigham.

Barber argues that the southern countries can no longer treat the Arctic as a remote wasteland, has no relation to areas with warmer climates.

"We need a clear understanding of the Arctic — it's just the first signs of what we can expect in the future. We, as a species, must do much more to take control of the situation with emissions of gases of greenhouse effect. "
