Humans must fight climate change to save polar bears, report says

The survival of polar bears depends on how well humans fight climate change, which is the biggest threat facing the giant carnivores, the five nations bordering the Arctic said today. Representatives from the U.S., Canada, Russia, Norway and Denmark noted with "deep concern" that global warming was melting the Arctic ice that is home to polar bears and their main prey: seals. "Climate change has a negative impact on polar bears and their habitat and is the most important long-term threat facing polar bears," the five nations said in a joint declaration after a three-day meeting in Tromsoe, northern Norway. Without action, 60 percent of the world's polar bears could disappear by 2050, Norway's Directorate for Nature Management said separately. The meeting in Tromsoe was the first time in 28 years the Arctic nations had reviewed their 1973 Polar Bear Agreement, meant to protect the world's estimated 20,000 to 25,000 polar bears. "The parties agreed that long term conservation of polar bears depends upon successful mitigation of climate change," the statement said, and called on other forums to take "appropriate action" to mitigate it. However, the statement did not do as the meeting's host, Norway, had asked. Norwegian officials had hoped for a direct appeal for action to the U.N. climate talks in December in Copenhagen, intended to produce a global climate treaty to replace the Kyoto Protocol, which expires in 2012...AP
