Where Trees Meet Tundra, Decoding Signals of Climate Change

In northern Alaska’s Brooks Range, the earth as most of us know it comes to an end. The northern tree line-a boundary that circles all of earth’s northern landmasses for more than 8,300 miles, and forms the planet’s biggest ecological transition zone–runs through here. Scientists from Columbia University’s Lamont-Doherty Earth Observatory are studying how climate may change it, and the tundra beyond.
