NEW YORK, Nov. 10 (UPI) -- Evergreen trees at the edge of Alaska's tundra are growing faster, suggesting forests may be reacting and adapting to rapidly warming climate, researchers say.
Scientists from Columbia University's Lamont-Doherty Earth Observatory said while forests elsewhere are thinning from wildfires, insect damage and droughts partially attributed to global warming, some white spruce trees in the far north of Alaska have grown more vigorously in the last hundred years, especially since 1950.
