Rising Acidity Threatens Oceans
January 30, 2009 09:10 AM - NY Times

The oceans have long buffered the effects of climate change by absorbing a substantial portion of the greenhouse gas carbon dioxide. But this benefit has a catch: as the gas dissolves, it makes seawater more acidic. Now an international panel of marine scientists says this acidity is accelerating so fast it threatens the survival of coral reefs, shellfish and the marine food web generally.

Australian heatwave sign of climate change

SYDNEY (Reuters) - A heatwave scorching southern Australia, causing transport chaos by buckling rail lines and leaving more than 140,000 homes without power, is a sign of climate change, the government said on Thursday.

Where warming hits hard

Threatened with encroaching seas, dwindling water supplies and fiercer storms, Bangladesh is already suffering the ill effects of rising global greenhouse gas emissions. Mason Inman reports on how the region is coping with climate change.

How Meat Contributes to Global Warming
January 28, 2009 09:43 AM - Scientific American

Most of us are aware that our cars, our coal-generated electric power and even our cement factories adversely affect the environment. Until recently, however, the foods we eat had gotten a pass in the discussion. Yet according to a 2006 report by the United Nations Food and Agriculture Organization (FAO), our diets and, specifically, the meat in them cause more greenhouse gases carbon dioxide (CO2), methane, nitrous oxide, and the like to spew into the atmosphere than either transportation or industry. (Greenhouse gases trap solar energy, thereby warming the earth's surface. Because gases vary in greenhouse potency, every greenhouse gas is usually expressed as an amount of CO2 with the same global-warming potential.)

Obama acts to reverse Bush climate moves: officials
January 26, 2009 09:58 AM - Reuters

WASHINGTON (Reuters) - U.S. PresidentBarack Obama will start reversing former President George W. Bush's climate change policies on Monday with steps to raise fuel efficiency standards and grant states authority to limit greenhouse gas emissions from cars. An administration official said late on Sunday that Obama, who took office last week, would direct the Environmental Protection Agency to reconsider a request by California to impose its own strict limits on automobile carbon dioxide emissions.

Global warming could suffocate the sea
January 26, 2009 09:50 AM - New Scientist

Fish could vanish from huge stretches of the ocean for tens of thousands of years unless we drastically reduce our carbon emissions. Gary Shaffer of the University of Copenhagen, Denmark, and his colleagues used computer models to analyse the long-term impact of global warming on the oceans, looking up to 100,000 years into the future. This is important because less oxygen dissolves in warmer water, affecting the amount of life the oceans can support.

All Antarctica seems to be warming, report says
January 23, 2009 08:08 AM - the San Francisco Chronicle

The climate trend that is raising temperatures across most of the world is warming all of Antarctica despite earlier signs that most of the ice-covered continent has cooled during the past 50 years, researchers are reporting today.

Even Antarctica is now feeling the heat of climate change
January 22, 2009 09:46 AM - New Scientist

It's official: there is nowhere left to hide from global warming. The notion that Antarctica is the last continent not to be heating up because of climate change is dead, according to a new study. The results suggest that the southernmost continent is warming roughly as fast as the rest of the planet. They overturn previous suggestions that only the Antarctic peninsula, which stretches points north towards South America, was heating up while the continent's interior cooled.

WWF: Bush Arctic Policy Should Be Obama's Starting Point, Not End Point
January 22, 2009 09:39 AM - WWF

Bill Eichbaum, vice president of WWF’s marine portfolio, issued the following statement: “Climate change is altering the Arctic in dramatic and dangerous ways. The rapid rate at which the Arctic is melting is spurring a race to exploit the region’s previously inaccessible resources and poses new challenges for governing territorial claims, ensuring shipping safety and managing fisheries.

Tibet shepherds live on climate frontier
January 22, 2009 09:01 AM - The Christian Science Monitor

For Tenzin Dorje, the road home keeps getting longer. Each year the Tibetan shepherd must walk farther to find streams where his sheep can drink. "I am an old man," he says, clutching the neck of his cane. Sometimes he trudges six hours a day, twice his old route. He has contemplated learning to ride a motorbike like his grandson, but fears it might be too discomfiting for an 80-year-old man.
