Environmental groups accused the Obama administration on Thursday of failing to ensure the survival of polar bears, after the administration declined to list the Arctic animals as endangered. "The Obama administration delivered a lump of coal to the polar bear for Christmas," said Kassie Siegel of the Center for Biological Diversity in a statement. The administration has "sacrificed sound science for political expediency," the AFP news agency quoted her as saying. The Center for Biological...

Researchers say polar bears could face brighter future "When I first picked up the cub, she was biting my hand," explains wildlife biologist Bruce Marcot. He was trying to calm the squirming cub while its sedated mother slept nearby. In the snowy spring of 2009, Portland-based Marcot traveled with several colleagues onto the frozen Arctic Ocean north of Alaska to study and survey polar bear populations. From their base of operations at the settlements of Deadhorse, next to Prudhoe Bay,...

According to a new study released Wednesday, there is no "tipping point" beyond which climate change will eventually push the Arctic icecap into a total melt off. Over the past 30 years the polar icecap has shrunk between 15 and 20 percent causing much concern that with current trends -- with regional temperatures increasing two to three times the global average -- it could disappear entirely during the summer months by the end of this century. One factor in this calculation is a so-called...

Polar bears may be able to survive the damage done to their native habitats due to greenhouse gas emissions, oil, and pollution, only to die out due to inter-species mating, scientists reported in two separate studies Wednesday. The iconic Arctic bears, which were originally added to the threatened species list in 2008 because of the effect of global warming on the ice-covered environments they call home, could continue to survive and thrive if stricter limits are placed on the emissions that...

A new study has found that climate change will trigger a dramatic and sudden decline in the number of polar bears. The research is the first to directly model how changing climate will affect polar bear reproduction and survival. Based on what is understood about a polar bear's physiology, behavior and ecology, the study predicts that pregnancy rates will fall and fewer bears will survive fasting during longer ice-free seasons. These changes will take place suddenly as bears pass a...

DOHA, Qatar, March 18 /PRNewswire-USNewswire/ -- Ignoring the plight of polar bears, CITES Parties gathered in Doha at the 15th Conference of the Parties (CoP 15) of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) voted to hasten the polar bear's demise by failing to support an uplisting to Appendix I which would have banned all international commercial trade in the bears and their parts. "CITES parties have turned their backs on this iconic...

Researchers sequence the oldest ancient genome to date from a mammal A rare, ancient polar bear fossil discovered in Norway in 2004 is yielding a treasure trove of essential information about the age and evolutionary origins of the species whose future is now seen as synonymous with the devastation wrought by climate change. A paper published in the current issue of the Proceedings of the National Academy of Sciences by researchers at Penn State University, the University at Buffalo, the...

Queen's researchers combine Inuit skills, DNA analysis in integrated method A new approach to tracking polar bears, developed by Queen's University researchers, will shed more light on the potentially endangered Arctic animal and help boost the economy of Canada's north. Integrating the traditional knowledge of Inuit hunters with state-of-the-art genetic DNA analysis, a three-part method developed by biologists Peter V.C. de Groot and Peter Boag, is cheaper and much easier on the bears than...

A U.S. study refutes a publicized criticism of the negative effects of climate change on polar bears, supporting the listing of them as a threatened species. The study -- conducted by scientists from the U.S. Geological Survey, the Woods Hole Oceanographic Institution, the Universities of Alaska and Maryland, the Canadian Wildlife Service and the U.S. Forest Service -- refutes point-by-point the criticism of negative polar bear population predictions. The new study is said to reinforce the...
