Greening Tundra Shows Impacts of Spreading Warmth
Greening Tundra Shows Impacts of Spreading Warmth - The Arctic is on the move. The North Pole is in the same place, but Arctic conditions have begun to shift. A study of 30 years of satellite data confirms that the difference in temperatures between the seasons has diminished. Conditions now have shifted the equivalent of four or five degrees of latitude southward. At the same time, vegetation has moved north, colonizing the thawing permafrost.

Nunavut, Canada - For thousands of years, the Inuit have coexisted with walruses, polar bears, and seals in Nunavut, a 1.2 million-square-mile Arctic region. Both humans and mammals rely on the ice, but rising temperatures over the next century are expected to keep the sea ice melted for most of the year, threatening the region’s wildlife and indigenous population.
