December 1, 2008 09:04 AM -

A year-long push to devise a new global climate-change treaty — one that picks up where the Kyoto Protocol leaves off — gets under way Monday in Poland, with delegates from more than 190 nations set to resume grappling with the thorny issues of how much more to cut greenhouse-gas emissions and who will pay.

This year's round of UN climate talks are opening in Poland with nations attempting to set the terms of a new deal on all aspects of climate change. The talks, in the city of Poznan, mark the halfway point in a two-year process agreed at last year's UN conference.

Climate change remains a top priority

Skeptics believed that the fiscal crisis would force Obama to put his plans to address global warming on the back burner. But in a videotaped speech to a climate summit co-hosted by California Gov. Arnold Schwarzenegger this month, Obama said, "Now is the time to confront this challenge once and for all. Delay is no longer an option."

GENEVA (Reuters) - Gases blamed for global warming reached record levels in the atmosphere last year, the United Nations weather agency said on Tuesday. Concentrations of carbon dioxide (CO2) and nitrous oxide (N2O) touched new highs after more steady rises in 2007, and methane had its largest annual increase in a decade, the World Meteorological Organization said.

Climate change wiped out cave bears 13 millennia earlier than thought
November 26, 2008 09:40 AM - Wiley-Blackwell

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.

Melting Arctic, Afghanistan top general's concerns
November 25, 2008 09:29 AM -

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.

Tibetan glaciers rapidly melting
November 25, 2008 09:25 AM -

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.

Downturn tests resolve at U.N. climate talks

OSLO (Reuters) - The economic downturn will test the world's resolve to do more to fight global warming at 190-nation talks in Poland next week, but the election ofBarack Obama as U.S. president should temper the gloom. The December 1-12 meeting of 8,000 delegates in Poznan, Poland, will review progress in a two-year push to work out a sweeping new U.N. climate treaty by the end of 2009.

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."
