Scientists at Arctic research station take pulse of the warming Earth

[XemaSab]

Beyond the Arctic Circle, teams of scientists measure widening slumps as ice melts beneath the tundra. They scuff through tussocks blackened by unexpected fires, and search for fish in drought-depleted streams.

The researchers are taking the pulse of a warming Earth in a landscape supremely adapted to cold, one that may be an early-warning zone for lands far south.

Some researchers, though, are resigned to changes they see as inevitable, and thus more careful about projections of how warming might play out in the lower 48.

Vladimir Romanovsky, a University of Alaska permafrost specialist who has been tracking temperatures in bore holes, can't understand why today's culture seems to believe every species must to be saved.
