Researchers in the United States say that it is one of the clearest signs yet that human activity is warming the planet.

Scientists have produced evidence showing dramatically that the current temperature rise there is highly unusual. For most of the last two thousand years, the Arctic slowly cooled, aconsequence of variations in the Earth's orbit.

But over the last century, the cooling abruptly reversed, and the region is now warmer than at any time in the 2,000 year record. Writing in the journal Science, the researchers say this shows how quickly the Arctic responds toclimatic changes.
