For Leslie Holland-Bartels of the U.S. Geological Survey (USGS), the inclusion of Alaska’s polar bears as a threatened species under the Endangered Species Act was a great accomplishment. But the 2008 federal designation also signaled much more — the broader scientific linkage between global warming and significant changes to wildlife, critical ecosystems and biodiversity. Working [...]

Scientists say shrinking Arctic sea ice may be forcing some polar bears into cannibalizing young cubs. “When (bears) are very hungry, they go looking for something to eat,” biologist Ian Stirling said Friday. “There’s nothing much to eat along the Hudson Bay coast in the fall other than other bears.” So far this fall, tour [...]

WINNIPEG–One of Canada’s top northern researchers says the permanent Arctic sea ice that is home to the world’s polar bears and usually survives the summer has all but disappeared. Experts around the world believed the ice was recovering because satellite images showed it expanding. But David Barber says the thick, multi-year frozen sheets crucial to [...]

The prospect of a four-degree Celsius rise in global average temperatures in 50 years is alarming – but not alarmist, climate scientists now believe. Eighteen months ago, no one dared imagine humanity pushing the climate beyond an additional two degrees C of heating, but rising carbon emissions and inability to agree on cuts has meant [...]

Nasa’s James Hansen was the first to point out the perils of climate change to the US Congress. Here, he begins a heated debate with experts from around the world, from China to the threatened Maldives, and argues that our leaders must be shaken out of their complacency. But will they show enough courage at [...]

A respected British scientist has admitted that emails taken from his inbox, calling into question many of the accepted truths of global warming, were genuine. The documents appear to show scientists are holding back, or ignoring, evidence. One even suggested using a “trick” to hide a trend of falling temperatures. var showHover=false;

Commonwealth leaders have backed a multi-billion-dollar plan to help developing nations to deal with climate change and cut greenhouse gases. The fund, proposed by UK and French leaders at the Commonwealth summit on Friday, would start next year and build to $10bn annually by 2012. Many Commonwealth members are island states threatened by rising sea [...]

Ten days before the UN climate conference opens in Copenhagen, EU officials welcomed emissions pledges by China and the US as a crucial step towards an agreement, but stressed that the commitments had to match the developed world’s ”common target” of keeping global warming below 2°C. “We will continue to urge the US, China and all our other partners in [...]
