Once reducers of CO2, Canada's trees now contribute to global warming
January 8, 2009 09:04 AM - World Business Council for Sustainable Development
In an alarming, yet little noticed series of recent studies, scientists have determined that Canada's 1.2 million square miles of forests have become so stressed from damage caused by global warming, insect infestations and persistent fires that they have crossed an ominous line and now pump out more carbon dioxide than they take in. The trees make up more than 7 percent of Earth's total forest lands and have been dubbed the "lungs of the planet" because they could always be depended upon to suck in vast quantities of carbon dioxide, naturally cleansing the world of some of the harmful heat-trapping gas.
Climate Road Trip: An Indian Movement for Change
January 7, 2009 08:26 AM - WorldWatch Institutue
Anna da Costa, co-director for the India Climate Solutions Project, reports on the launch of the Indian Climate Solutions Road Tour, aimed at catalyzing and inspiring climate change solutions across India. As clocks ticked past midnight on December 31, signaling the start of the new year, a group of seven passionate individuals from India and around the world gathered in the eastern city of Chennai to begin an epic climate journey.
The mystery of Antarctica's speeding glacier
January 6, 2009 09:13 AM - telegraph.co.uk/
With the possible exception of the ice that covers Greenland, the West Antarctic ice shelf is the most important body of water in the world. If it thaws, the results will be disastrous for millions, raising sea levels and flooding coastal cities such as London, New York, Tokyo and Calcutta. So it is understandable that scientists are alarmed as to why one particular section of it - Pine Island Glacier - is melting so much faster than the rest.
Earthtalk: Rising Seas and Buying a New Car Vs. Keeping a Well-Maintained Used Car
January 6, 2009 08:26 AM - Earth Talk
Dear EarthTalk: With all the talk of rising seas, what could happen to the rivers that flow into the oceans? Will they reverse flow? Will rising seas back up into fresh water lakes? And what happens to our groundwater should saltwater flow backwards into it? - Sandy Smith, concerned Michigander
EU seals historic climate and energy package
January 3, 2009 08:02 AM - World Business Council for Sustainable Development
MEPs formally approved an unprecedented package of six new climate and energy laws in Strasbourg on Wednesday. A year of intense negotiations was wrapped up in a mere twenty minutes of voting. Over 550 MEPs backed the package, while fewer than 100 voted against. The package is designed to cut EU greenhouse gas emissions by twenty per cent by 2020 compared with 1990 levels, as pledged by European leaders at their spring summit in 2007. The EU will aim for a 30 per cent cut if other industrialised countries take on equivalent commitments in a new international climate treaty to be agreed at UN talks in Copenhagen next December.
The big melt: 2 trillion tons of ice since 2003
January 2, 2009 08:57 AM - Stop Global Warming
More than 2 trillion tons of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming. More than half of the loss of landlocked ice in the past five years has occurred in Greenland, based on measurements of ice weight by NASA's GRACE satellite, said NASA geophysicist Scott Luthcke. The water melting from Greenland in the past five years would fill up about 11 Chesapeake Bays, he said, and the Greenland melt seems to be accelerating.
Official figures mask true state of environment
January 1, 2009 10:00 AM - The Sydney Morning Herald
THE rate of land clearing is much higher than Australia's environmental accounting methods may suggest, a study by researchers at the University of Queensland shows. It says traditional bookkeeping methods are misleading because they usually record positive and negative environmental outcomes separately, and that lack of context means big net losses of forested land can be wrongly reported as a win for conservation.
Stern hope over US climate deal
January 1, 2009 09:24 AM - BBC
Economist Lord Stern has said he is optimistic a global deal to reduce carbon dioxide emissions will be struck under Barack Obama's US presidency. Lord Stern, who was behind the first detailed economic assessment of the impact of climate change, said US and Chinese agreement to a cut was crucial.
Bush may be giving Obama breathing room to fight global warming
January 1, 2009 09:11 AM - LA Times
Recent moves by lame-duck officials, though frustrating to environmentalists, offer the president-elect time and political cover to deliberately craft rules on emissions, energy lobbyists say. Reporting from Washington -- President Bush could be forcing President-elect Barack Obama to act almost immediately to curb global warming, after years of the Bush administration fighting attempts to crack down on greenhouse gas emissions.
Coping With Climate
December 31, 2008 09:28 AM - Newsweek
Developing nations will bear the brunt of global warming. Public-private partnerships can help. Even if the world were to take steps to quickly and dramatically limit greenhouse-gas emissions, the levels already in the atmosphere will continue to alter our climate in the coming decades. As the focus of the debate on global warming shifts to assessing the impact of rises in temperature and coping with their effects, it has become increasingly clear that the developing world will face some of the greatest challenges. Dealing with this problem will require broad partnerships between public, private and nonprofit organizations.
