The gene that regulates the work of stomata, or pores on plant leaves, has been sought by biologists for decades. The gene...

CO2 Emissions Linked to Human Death

Stanford study may bolster states' case against EPA

(Newser) - A Stanford University scientist has found for the first time a direct correlation between rising atmospheric carbon dioxide and increased human mortality—potentially aiding 16 states in their fight to regulate auto emissions. The air pollution spurred by each 1 degree Celsius caused by carbon dioxide leads to 1,000...

Sham Study Tricks Climate Skeptics

Warming blamed on bacteria; pundits trumpeted the news

(Newser) - Turns out undersea bacteria don’t cause global warming after all. But they were on trial for 70 minutes last week after a British prof's email chain linked to a sham study. Climate skeptics and conservatives—Rush Limbaugh included—trumpeted the study until a University of Colorado prof smelled something...

83% Back Sacrifice to Fight Warming

But global survey mixed on higher fuel taxes

(Newser) - Four out of five people worldwide indicated they're ready to make personal lifestyle changes to combat global warming—even those from the worst carbon dioxide spewers, China and the US, according to a BBC poll of 22,000 people. Support was mixed, however, on increasing taxes on coal and oil,...

Oceans Are Absorbing Less CO2

(Newser) - Oceans are absorbing half the CO2 they were in the mid-'90s, according to a study that collected more than 90,000 North Atlantic measurements over 10 years. Oceans typically absorb about a quarter of the world’s carbon emissions, but the new data suggest they're becoming “saturated,” which...

Bedbugs Make Bloodthirsty Comeback

Once thought gone for good, pests are on the rebound in US

Iowa-Minded Candidates Learn to Love Ethanol

Doubts take back seat to politics

Global Warming Battle Goes Out to Sea

Investors back plankton in bid to send CO2 to a watery grave

(Newser) - Plankton may hold the key to solving global warming—or so say Silicon Valley entrepreneurs who are investing heavily in the idea. Scientists will dump several tons of plankton-producing iron into the ocean to see if the microscopic organisms will, as they expect, suck CO2 from the atmosphere and carry...

Travel to Big Sky Is Killing It

(Newser) - Big Sky Country is under siege from the carbon spewed by the planes and cars we use to get there, says Montanan Deirdre McNamer. She remembers the days (the 1950s) when it was not politically incorrect to throw litter into the vastness of the high prairie that she thought could...

Sorry, Al: Tree Planting May Speed Warming

Outside the tropics, trees merely trap heat, study shows

(Newser) - Planting trees to offset your carbon footprint not only won't slow global warming, it may worsen its effects, a new study claims. Trees growing outside a small band of tropical zones don't cut the amount of greenhouse gases in the atmosphere by enough to offset the heat their foliage traps,...

Supreme Court ruling a rebuke to Bush's hands-off policy on auto emissions
