(03/07/2011) In Shakespeare's play Macbeth the forest of Birnam Wood fulfills a seemingly impossible prophecy by moving to surround the murderous king (the marching trees are helped, of course, by an army of axe-wielding camouflaged Scots). The Arctic tundra may soon feel much like the doomed Macbeth with an army of trees (and invading species) closing in. In a recent study, researchers found that climate change is likely to push the northern forests of the boreal into the Arctic tundra—a trend that is already being confirmed in Alaska.
(11/23/2010) A thousand square kilometers of the Alaskan tundra burned in September 2007, a single fire that doubled the area burned in the region since 1950. However, a new study in the Journal of Geophysical Research finds that the fire was even more unprecedented than imagined: sediment cores found that it was the most destructive fire in the area for at least 5,000 years and maybe longer. "If such fires occur every 200 years or every 500 years, it's a natural event," University of Illinois plant biology professor Feng Sheng Hu explains in a press release. "But another possibility is that these are truly unprecedented events caused by, say, greenhouse warming."
(06/14/2009) The first ever comprehensive survey of caribou worldwide (known as reindeer in Europe) has found that the species has suffered a staggering decline. Researchers from the University of Alberta discovered that the caribou population has fallen 60 percent in half as many years. The study published in Global Change Biology points to global warming and industrial development as the reasons behind the decline.
