A group of endangered North Atlantic right whales has been identified near Greenland in an area where the species was thought to be extinct, using a system of underwater microphones.

Yosemite's giant trees disappear
May 23, 2009 07:31 AM - Matt Walker, Earth News

The oldest and largest trees within California's world famous Yosemite National Park are disappearing. Climate change appears to be a major cause of the loss. The revelation comes from an analysis of data collected over 60 years by forest ecologists.

Shellfish reefs are 'most imperilled sea habitat'
May 22, 2009 07:34 AM - Peter Aldhous, New Scientist

Globally, 85 per cent of reefs have been lost. Destructive fishing practices, disease and coastal development threaten many of the survivors. What sounds like an apocalyptic vision of the future for the world's tropical corals is in fact a chilling assessment of the current state of reefs built in cooler waters by oysters and other bivalve shellfish.

U.S. Carbon Emissions Fall by Most Since '82
May 21, 2009 10:58 AM - Steven Mufson, Washington Post

U.S. emissions of carbon dioxide related to energy use fell 2.8 percent last year, according to an estimate by the Energy Information Administration, driven down by high oil prices and the sagging economy.

Drain rice fields to cut methane, say scientists
May 21, 2009 09:33 AM - Gina Lin, SciDevNet

Global methane emissions from rice paddies could be cut by 30 per cent if fields are drained at least once during the growing season and rice crop waste is applied off-season, according to a study.

New auto standards: the start of Obama’s green revolution

President Obama’s announcement on tailpipe emissions Tuesday reaffirmed a commitment that goes beyond regulation of the auto industry. The move is part of a broader White House strategy to confront the risk of global warming while making green-collar jobs a centerpiece of the economy. For ordinary Americans, the resulting changes could be far-reaching. Lighter-weight vehicles appear likely to become more popular. More tax dollars are being tabbed for clean-energy technology. And for years to come, college students might find that some of the hottest job opportunities lie in helping to keep the planet cool.

Russia's climate policy fails to raise hopes

Russia's new climate doctrine hints at Moscow's growing willingness to engage with the international community in fighting climate change, but EU observers are not pinning their hopes on ambitious commitments from their Eastern neighbour to aid the passage of a post-Kyoto climate treaty.

Stanford scientists find heat-tolerant coral reefs that may resist climate change
May 20, 2009 09:39 AM - Stanford University via EurekAlert

Experts say that more than half of the world's coral reefs could disappear in the next 50 years, in large part because of higher ocean temperatures caused by climate change. But now Stanford University scientists have found evidence that some coral reefs are adapting and may actually survive global warming.

Climate Change Odds Much Worse Than Thought
May 20, 2009 06:40 AM - ScienceDaily

The most comprehensive modeling yet carried out on the likelihood of how much hotter the Earth's climate will get in this century shows that without rapid and massive action, the problem will be about twice as severe as previously estimated six years ago - and could be even worse than that.

Summer haze has a cooling effect in southeastern United States, says new study

Global warming may include some periods of local cooling, according to a new study by researchers at the University of California, Berkeley. Results from satellite and ground-based sensor data show that sweltering summers can, paradoxically, lead to the temporary formation of a cooling haze in the southeastern United States.
