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.

Obama to Tighten Fuel-Economy Standards
May 19, 2009 06:07 AM - Bryan Walsh, TIME

In a landmark decision on climate change and energy, President Barack Obama will announce tough new vehicle gas-mileage standards on Tuesday, the first ever national limits on greenhouse-gas emissions. The new policy, which was worked out between Washington, state governments and the auto industry, will require automakers to meet a minimum fuel-efficiency standard of 35.5 miles a gallon by model year 2016 — four years earlier than Congress currently requires.

As Alaska Glaciers Melt, It’s Land That’s Rising
May 18, 2009 06:21 AM - CORNELIA DEAN, The New York Times

Global warming conjures images of rising seas that threaten coastal areas. But in Juneau, as almost nowhere else in the world, climate change is having the opposite effect: As the glaciers here melt, the land is rising, causing the sea to retreat.

Climate Bill CO2 Allocations Strategy
May 16, 2009 10:37 AM - Reuters

The climate change bill moving through the U.S. Congress would initially give away the majority of permits to emit greenhouse gases to entities like electricity distributors and big energy users, such as steel and cement plants, in a cap and trade program.

New Ocean Circulation Experiment has Potential Big Climate Model Impact
May 15, 2009 02:00 PM - Editor, ENN, based on an artilce from eurekalert

New research by Duke University, in conjunction with the Woods Hole Oceanographic Institution is casting doubt on long-held theories of North Atlantic Ocean circulation patterns. This research, supported by the National Science Foundation is important since oceanic circulation is one of the key factors in current atmospheric circulation models, and therefore critical starting points for climate modeling.
