Global Warming Puts Peary Caribou on Canadian Endangered Species List

Canada's environment minister has added the Peary caribou to its endangered species list and placed a one-year deadline on developing a management plan to maintain the species at current population levels. The island-based caribou has seen its population drop from 50,000 to 8,000 over the last 30 years.

Scientists have blamed global warming for the decline, saying warmer weather has increased the amount of frozen rain in the province of Nunavut, which has locked the Peary caribou's main sources of vegetation beneath impenetrable ice.
