Global Warming Blamed for Dwindling Caribou Herds. By Charles J. Hanley, AP, October 4, 2009. "On the endlessly rolling and tussocky terrain of northwest Canada... the vast antlered herds are fast growing thin. And it's not just here. Across the tundra 1,500 kilometers (1,000 miles) to the east, Canada's Beverly herd, numbering more than 200,000 a decade ago, can barely be found today. Halfway around the world in Siberia, the biggest aggregation of these migratory animals, of the dun-colored herds whose sweep across the Arctic's white canvas is one of nature's matchless wonders, has shrunk by hundreds of thousands in a few short years... The decline of the caribou -- called reindeer in the Eurasian Arctic -- has biologists searching for clues, and finding them. They believe the insidious impact of climate change, its tipping of natural balances and disruption of feeding habits, is decimating a species that has long numbered in the millions and supported human life in Earth's most inhuman climate. Many herds have lost more than half their number from the maximums of recent decades, a global survey finds."
