Enormous cave bears, Ursus spelaeus, that once inhabited a large swathe of Europe, from Spain to the Urals, died out 27,800 years ago, around 13 millennia earlier than was previously believed, scientists have reported. The new date coincides with a period of significant climate change, known as the Last Glacial Maximum, when a marked cooling in temperature resulted in the reduction or loss of vegetation forming the main component of the cave bears' diet.

OTTAWA - Global warming is melting Arctic ice faster than the military projected, posing greater challenges for Canadian Forces already facing a deteriorating security situation half a world away in Afghanistan, says Canada's top soldier. "Global warming is happening very quickly. I think any projection we have has been underestimated. Flying over Ellesmere Island and not seeing very much snow up there and seeing the Arctic Ocean as a blue water ocean was quite revealing to me," Gen. Walt Natynczyk, the chief of the defence staff, said Monday in a candid and sweeping assessment of the challenges faced by the military from the sun-baked deserts of Afghanistan to the not-so-frozen Far North.

Glaciers high in the Himalayas are dwindling faster than anyone thought, putting nearly a billion people living in South Asia in peril of losing their water supply. Throughout India, China, and Nepal, some 15,000 glaciers speckle the Tibetan Plateau. There, perched in thin, frigid air up to 7200 metres above sea level, the ice might seem secluded from the effects of global warming.

Southern Ocean changing but still major CO2 sink: study
November 24, 2008 08:55 AM - Reuters

SINGAPORE (Reuters) - The Southern Ocean has proved more resilient to global warming than previously thought and remains a major store of mankind's planet-warming carbon dioxide, a study has found. Oceans absorb a large portion of the extra CO2 released by mankind through burning fossil fuels or deforestation, acting as a brake on climate change, and the Southern Ocean is the largest of these "carbon sinks."
