Soaring demand for flat-screen TVs could accelerate global warming faster than coal-fired power stations, the Guardian reports. A leading environmental scientist warns that a gas used in their manufacture and not controlled in the Kyoto treaty—as other greenhouse gases are—is 17,000 times more potent than carbon dioxide and is being made in escalating amounts.

A team of American scientists says it's taken an important first step toward creating a so-called carbon scrubber that can rid greenhouse gases from the air, the Guardian reports. The scientists, led by a Columbia University physicist, have a prototype in the works that can suck a ton of carbon dioxide out of the air per day—and do so economically. More »

Ambitious plans to combat global warming by pumping carbon dioxide from coal-burning power plants into the ground have been delayed or canned due to spiraling costs, the New York Times reports. Scientists now fear that the next generation of coal-burning plants will be built using old, emission-spewing technology, spelling disaster for the climate. More »

Car ads in Europe will soon have to highlight gas mileage and carbon dioxide emissions under regulations in the works from the European Union, Der Spiegel reports. EU commissioners hope regulating ads will motivate more Europeans to ditch gas-guzzling models, but manufacturers and media execs aren’t happy. The plan could push some automakers to drop their advertising altogether. More »

Bad news on the climate-change front: Airplanes are emitting 20% more carbon dioxide than anyone thought. According to a newly disclosed report, they could release 1.5 billion tons a year by 2025—compared to 3.1 billion tons a year now released by all the citizens of the EU, reports Wired. The study also predicted growing airplane noise pollution. More »

Green was the color of opening day yesterday at the International Auto Salon in Geneva, another show full of hybrids and other low-emission vehicles, with green lighting and nature-friendly slogans to prove car companies care, Der Spiegel reports. Still, cautions General Motors' CEO to those set to pronounce the gasoline era dead, "We're just at the beginning of this changeover." More »

Scientists have discovered a gene that controls how plants absorb carbon dioxide and release moisture in a breakthrough discovery that could help develop drought-resistant crops, reports the BBC. The gene that regulates the work of stomata, or pores on plant leaves, has been sought by biologists for decades. The gene also controls the amount of water vapor a plant releases into the atmosphere, and its manipulation could affect climate change. More »

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 US deaths—and as many as 20,000 worldwide, Wired reports. More »

The triumph of the Bali summit may be its plan to stop deforestation, but rich and poor nations are still clashing over details, the Washington Post reports. A dozen developing countries want incentives to stop tree-cutting, but some developed nations wince at paying them for actions not taken. "The problems tend to start when you get down to the small print," said a UN official. More »

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 rotten. “Call me a skeptic skeptic—I smell a hoax,” he posted.

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, though most agreed a price increase would curb their use. More »

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 a BBC analyst says would “leave all our emissions to warm the atmosphere.” More »

Despite admonitions about not letting the bedbugs bite, Americans are doing just that, and infestations are being reported across the country. Once thought wiped out by the now-banned pesticide DDT, the insects have been found in hospitals, schools, and even high-end residences, the Times of London reports. "Saturday Night Live" star Maya Rudolph is suing her landlord over an infestation. More »

To a presidential candidate who has an eye on Iowa—and who among them can afford not to?—ethanol is a political home run. The Hawkeye State hosts 28 refineries, and every one of the ’08 hopefuls has duly supported some form of ethanol subsidies. This despite the fact that, as Politico notes, reservations about ethanol as an alternative energy source have reached a fever pitch.  More »

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 it to the ocean floor.

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 never be affected by the humans it dwarfed.

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, says atmospheric scientist Govindasamy Bala in the Guardian .

The obligation of people who live in countries that contribute the most to climate change--the developed nations— to those who will suffer most from it —the poor ones—is the subject of a provocative piece in the New York Times. More »

Carbon dioxide must be regulated by the federal government unless it can provide a scientific reason not to, the Supreme Court ruled Monday. The 5-4 decision, which ordered the EPA to consider CO 2 an "air pollutant" as defined by the Clean Air Act, was a blow to the Bush administration's policy of refusing to regulate factory and automobile emissions.  More »
