Aerosols' complicated influence on our climate just got more threatening: they could make methane a more potent greenhouse gas than previously realized, say climate modellers.Drew Shindell, at NASA Goddard Institute for Space Studies, New York, and colleagues ran a range of computerized models to show that methane's global warming potential is greater when combined with aerosols — atmospheric particles such as dust, sea salt, sulphates and black carbon. The International Panel on Climate Change (IPCC) and treaties such as the Kyoto Protocol assume methane to be, tonne-for-tonne, 25 times more potent than carbon dioxide at warming the planet. But the...

SNIPPET: "(CNSNews.com) – President Barack Obama and First Lady Michelle Obama are both traveling to Copenhagen this week to promote Chicago's bid to host to the 2016 Olympic Games--and they will be making the 3,979-mile trip on separate airplanes." SNIPPET: "As reported earlier by CNSNews.com, a Congressional Research Service (CRS) report cited two cost estimates for an hour of air travel by the president, vice president and first lady. One estimate comes from the White House Military Office, the other from the U.S. Air Force. Using the CRS cost estimates and the inflation adjuster from the Bureau of Labor Statisitcs,...

Independent teams of researchers in the UK and the US have shown that nitrogen oxides in the atmosphere can participate in chemical reactions on the surfaces of buildings, indoors and outdoors, producing harmful pollutants including the respiratory irritant nitrous oxide, the toxic gas nitrosyl chloride and hydroxyl radicals. Rod Jones' team at the University of Cambridge in the UK investigated the fate of NO2 when it comes into contact with glass that has been coated with titanium dioxide.1 TiO2-coated glass is available commercially as a self-cleaning product in which the TiO2 photocatalytically degrades organic dirt in the presence of sunlight. In...

Alternative Energy: A government report says reliance on electric cars will do little to reduce greenhouse gas emissions and may merely shift our dependence on foreign sources from one set of dictators to another.It's a beautiful theory — highways full of electric cars emitting no greenhouse gases or pollutants after being plugged into an outlet in our garages overnight. The problem, according to a new Government Accountability Office report, is that the effort may only shift the problem somewhere else. "If you are using coal-fired power plants, and half the country's electricity comes from coal-powered plants, are you just trading...

Alternative Energy: A government report says reliance on electric cars will do little to reduce greenhouse gas emissions and may merely shift our dependence on foreign sources from one set of dictators to another..."If you are using coal-fired power plants, and half the country's electricity comes from coal-powered plants, are you just trading one greenhouse gas emitter for another?" asks Mark Gaffigan, co-author of the GAO report. The report itself notes: "Reductions in CO2 emissions depend on generating electricity used to charge the vehicles from lower-emission sources of energy."

The Environmental Protection Agency took a major step toward tougher reductions in greenhouse gas emissions from cars and trucks Tuesday by giving California the green light to impose new requirements that could become the national model for combatting tailpipe pollution linked to global warming. The EPA granted California's long-standing request — denied by the Bush administration — for a waiver to allow it to pursue more stringent air pollution rules than required by the federal government. It cleared the way to implement immediately a 2002 state pollution law requiring new cars to increase their fuel economy 40 percent by 2016....

LOS ANGELES – Sixty percent of Americans live in areas with unhealthy air pollution levels, despite a growing green movement and more stringent laws aimed at improving air quality, the American Lung Association said in a report released Wednesday. The public-health group ranked the pollution levels of U.S. cities and counties based on air quality measurements that state and local agencies reported to the U.S. Environmental Protection Agency between 2005 and 2007. Overall, the report found that air pollution at times reaches unhealthy levels in almost every major city and that 186.1 million people live in those areas. The number...

Aerosols bumped up world’s plant productivity by 25 percent in the 1960s and 1970s, new research suggests The world’s vegetation soaked up carbon dioxide more efficiently under the polluted skies of recent decades than it would have under a pristine atmosphere, a new analysis in the April 23 Nature suggests. The trend hints that relying on forests and other vegetation to sequester carbon may not be effective if skies continue to clear, researchers say. Major volcanic eruptions throw large quantities of aerosols, such as small bits of fractured rock and droplets of sulfuric acid, high into the atmosphere. Those particles...

Darker skies have uncertain effect on global warming.Air pollution that is harmful to human health has increased over all populated continents except Europe since 1973, according to an extensive survey.I can see dimly now: air pollution is on the rise in most areas of the world.punchstock The results play into a long-standing debate over whether the Earth's skies are dimming or brightening, how this affects the amount of sunlight reaching the planet's surface and what that means for climate change. Two studies published in Science in 2005 concluded that a global dimming trend that began in the 1950s has been...

FRESNO, Calif. (AP) - Lowering air pollution in Southern California and the San Joaquin Valley would save more lives annually than ending all motor vehicle fatalities in the two regions, according to a new study. The study, which examined the costs of air pollution in two areas with the worst levels in the country, also said meeting federal ozone and fine particulate standards could save $28 billion annually in health care costs, school absences, missed work and lost income potential from premature deaths.

The Milwaukee, Madison and Green Bay areas do not meet tough new air quality standards designed to protect public health and may need additional regulations, federal regulators said Tuesday. The Environmental Protection Agency's announcement drew criticism from a top state air official, who warned it could hurt economic development and do little to improve air quality.The EPA said its review found Brown, Columbia, Dane, Racine, Waukesha and Milwaukee counties have unacceptable levels of fine particulate matter in the air or contribute to problems in neighboring areas. The pollution is largely caused by coal-fired power plants and diesel engines and creates...

Dust storms that fouled Kern County’s air in May could mean months of delay for two major Kern County freeway projects. A project to widen Highway 46 from Holloway Road west to Highway 33 at Blackwells Corner will almost certainly be delayed for five months or more, said Ron Brummett, executive director of the Kern Council of Governments. And the Westside Parkway in Bakersfield, a freeway that’s to run west from a point near Highway 99 to Heath Road, might also be delayed if dickering over air quality standards goes on too long. The Environmental Protection Agency, Brummett said, is...

A judge in Georgia has thrown out an air pollution permit for a new coal-fired power plant because the permit did not set limits on carbon dioxide emissions. Both opponents of coal use and the company that wants to build the plant said it was the first time a court decision had linked carbon dioxide to an air pollution permit. The decision’s broader legal impact was not clear, either for the plant, proposed to be built near Blakely, in Early County, Ga., or for others outside Georgia, but it signaled that builders of coal plants would face continued difficulties in...

Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new University of Virginia study indicates. This could partially explain why wild populations of some pollinators, particularly bees – which need nectar for food – are declining in several areas of the world, including California and the Netherlands. The study appears online in the journal Atmospheric Environment. "The scent molecules produced by flowers in a less polluted environment, such as in the 1800s, could travel for roughly 1,000 to 1,200 meters;...

Cars have been a huge part of our lives. We use them to get around anywhere. It might have been the best invention mankind came up with, but we all hate several common things about cars, such as the cost of gas prices and traffic. We think sometimes in our imagination how awesome it would be if cars had wings, so maybe one day we will fly through terrific! We also despise accidents, high insurance and drunk driving. Sometimes, I feel that we need other alternative means of transportation, such as a subway system in the state of Texas; maybe...

Hydroxyl radicals, nature's atmospheric scrubbers, are produced by nitrogen pollution too. Some types of air pollution might be doing a good turn by creating extra doses of atmospheric cleaner, according to new research. A lab study has shown how nitrogen oxides, a largely agricultural pollutant, can help to make hydroxyl radicals — the natural cleaner-upper of our dirty atmosphere. But in doing so they can also produce more ozone, the major component of smog. The work should help to improve models of atmospheric chemistry, and suggest better ways to control air pollution in big cities. The hydroxyl radical is a...

Beijing events could be postponed in case of heavy pollution: IOC Monday • March 17, 2008 The International Olympic Committee said Monday that it would set up a special panel to recommend the postponement of events at the Beijing Olympics in case of heavy pollution. IOC Medical Commission chairman, Arne Ljungqvist, announcing the IOC's own analysis of air quality data for Beijing, said that the body would be formed with representatives from his commission and from sports federations. "We have to have a mechanism in place to provide the coordination commission with the facts," he said, referring to the IOC...

There's been a lot of talk about the new Trans-Texas Corridor — the next-generation "super-highway" — and opinions are varying. Now the debate is coming to Lufkin's doorstep. On Monday, the American Land Foundation, Stewards of the Range and TURF will hold a workshop at Lufkin's Pitser Garrison Civic Center on how to stop the Trans-Texas Corridor 69. The event runs from 9 a.m. to 3 p.m. A portion of Texas citizens have voiced their opposition to the TTC-69 in public meetings held by the Texas Department of Transportation, but believing they are not being heard, four cities and their...

Mention air pollution, and what comes to mind? Factories. Oil refineries. Auto tailpipes. Now Bay Area smog regulators are trying to crack down on another source that they say is just as significant, even if beloved: home fireplaces. Citing growing medical research that soot causes more severe health problems than was previously realized, the Bay Area Air Quality Management District is proposing a ban on all wood burning in fireplaces and wood stoves in the nine Bay Area counties during winter "Spare the Air" nights. --snip-- If approved, fireplace police would enforce the rules, and neighbors would be encouraged to...

McALLEN — In other parts of the state, transportation officials try to allay property owners' fears that a superhighway from Laredo north to Texarkana will result in a massive land grab. But in the lower Rio Grande Valley, the state's road builders spend more time assuring local leaders that they have a shot at being included. People in the fast-growing border area between Brownsville and McAllen have developed something of an inferiority complex about being the state's largest metropolitan area without an interstate highway. One after another, Valley leaders stepped to a microphone at public meetings last week and made...

When Kurt Hoffman visited Tanzania in the 1970s as a young product-development researcher, he could hardly bear to enter village huts to ask questions. “I couldn’t stand the smoke, the pain in my eyes and the coughing,” he said. “And yet the women and children were sitting there the whole time,” enveloped in smoke from traditional open pit fires or poorly functioning stoves. Some 30 years later, when Mr. Hoffman returned to the field in his position as director of the Shell Foundation, a charity in Britain established by the Shell Group, not much had changed. “To find that it...

BEIJING — Every day, monitoring stations across the city measure air pollution to determine if the skies above this national capital can officially be designated blue. It is not an act of whimsy: with Beijing preparing to play host to the 2008 Olympic Games, the official Blue Sky ratings are the city’s own measuring stick for how well it is cleaning up its polluted air. Thursday did not bring good news. The gray, acrid skies rated an eye-reddening 421 on a scale of 500, with 500 being the worst. Friday rated 500. Both days far exceeded pollution levels deemed safe...

Beijingers were warned to stay indoors on Thursday as pollution levels across the capital hit the top of the scale, despite repeated assurances by the government that air quality was improving. "This is as bad as it can get," a spokeswoman for the Beijing Environmental Protection Bureau told AFP. "Level five is the worst level of air pollution. This is as bad as it has been all year." According to the bureau's website, 15 out of the 16 pollution monitoring stations in urban Beijing registered a "five" for air quality rating. The main pollutant was suspended particulate matter, which is...

The energy bill to be signed by the president today is arguably the worst piece of energy legislation ever enacted into law. It will substantially increase the price of automobiles, increase highway fatalities, increase fuel prices, worsen air pollution, and force consumers to buy products (like super-efficient light bulbs) that they manifestly -- and for very good reason -- do not want to buy. It will transfer huge amounts of wealth from the consumer to the farm lobby in the course of promoting a dubious product -- ethanol -- that will make energy supplies less reliable and greenhouse gas emission...

Coin trays in Texas cars may actually get to see the faces of dead presidents. The much-discussed and controversial Trans-Texas Corridor, or TTC, has breathed life into the debate of toll roads in Texas. Plans for the Trans-Texas Corridor include TTC-Instate 35, which starts in Laredo and extends north to Gainesville, running along the eastern part of Texas; and Interstate 69/TCC, which has three openings in Laredo, McAllen and Brownsville and follows the coast to Texarkana. Much of the TTC will be privately operated toll roads, run by the Spanish firm Cintra. The TTC will not run through San Antonio,...

PARIS, Sept. 25 — A group representing some of the world’s leading banks will urge the United States and other industrial nations this week to move quickly to introduce a lightly regulated system for trading carbon emissions permits. Permit-trading systems offer banks a potentially vast new business. For it to grow, leading economies — particularly the United States — will need to set limits on the quantities of greenhouse gases that can be released and to allow companies in other parts of the world to buy emissions permits. “Where politicians opt to implement carbon constraints, then it should be cap-and-trade,”...

A Kern County dairy violated the federal Clean Air Act when it built a new plant before obtaining an air permit and complying with the latest air pollution requirements, a federal judge ruled Tuesday. The Center on Race, Poverty & the Environment sued C&R Vanderham Dairy nearly two years ago in U.S. District Court in Fresno, claiming the dairy needed to apply for an air permit before beginning construction. The plaintiffs argued that volatile organic compounds in decomposing dairy manure, livestock feed, and cows' digestive systems contributed to the region's polluted air. The San Joaquin Valley Air Pollution Control District...

They call it the Asian Brown Cloud. Anyone who has flown over South Asia has seen it – a vast blanket of smog that covers much of the region. It is also what colours those sunsets at the Taj Mahal. Now a group of scientists has carried out the first detailed study of the phenomenon and arrived at a troubling conclusion. They say that it is causing Himalayan glaciers to melt, with potentially devastating consequences for more than two billion people in India, China, Bangladesh and other downstream countries. In a study published yesterday by Nature, the British journal, they...

NEW YORK (AP) -- An image of a sad-looking little girl squeezing an asthma inhaler is being used to pressure state lawmakers into approving Mayor Michael Bloomberg's controversial plan to reduce traffic and pollution by charging motorists who drive into Manhattan. The tag line: ``She cannot hold her breath waiting for Albany to act.'' The flier is being mailed this week to 350,000 households throughout the city, urging residents to call lawmakers in Albany. The state legislature would have to come back for a special session to approve the plan before a July 16 application deadline for federal funding. Bloomberg's...

The current debate about global warming is "completely irrational," and people need to start taking a different approach, say two Ottawa scientists. Carleton University science professor Tim Patterson said global warming will not bring about the downfall of life on the planet. Patterson said much of the up-to-date research indicates that "changes in the brightness of the sun" are almost certainly the primary cause of the warming trend since the end of the "Little Ice Age" in the late 19th century. Human emissions of carbon dioxide (CO2), the gas of concern in most plans to curb climate change, appear to...

AUSTIN — Carrying signs with slogans of "Stop the Coal Rush" and "Shame on Texas," about 1,000 people rallied at the state Capitol on Sunday to call for lawmakers to slow down a plan to build up to 18 new coal-fired power plants. Environmentalists fear the new plants, with 11 proposed by energy giant TXU Corp., will pump millions of tons of pollutants into the air every year. "Coal plants seem so archaic," said Stacy Foss, an Austin teacher who brought her two young children to the rally in the 50-degree weather. "Texas is so environmentally incorrect." Organized by about...

KINGSPORT, Tenn. Motorists are warned to watch their speed on Interstate 81 after they cross into northeast Tennessee. The speed limit has dropped there, starting today. The Tennessee Department of Transportation is posting new lower speed limit signs. The speed limit for truckers will drop from 70-to-55 miles per hour. The new speed limit for everyone else will be 65 miles per hour. The reductions will affect more than 22 miles on I-81 and 12-and-a-half miles on I-26, from the Tennessee-Virginia border to the Sullivan-Washington county line. Local officials requested the change to help bring the county into line with...

Elected officials, business leaders and environmental watchdogs, invited by the editorial board, recently met at The Dallas Morning News to discuss clean air issues. This is the first of three excerpted transcripts from the roundtable. The speakers quoted: Colleen McCain Nelson, editorial writer; Margaret Keliher, Dallas County judge through 2006; Richard Greene, regional administrator for the Environmental Protection Agency; Tom "Smitty" Smith, director of Public Citizen's Texas office; Jim Schermbeck, Downwinders at Risk board member; Todd Campbell, director of public policy for Clean Energy and mayor of Burbank, Calif.; Al Armendariz, assistant professor, SMU School of Engineering; Robert Cluck, Arlington...

WASHINGTON - Environmental groups filed two court challenges Wednesday aimed at blocking construction of Maryland's Intercounty Connector, a highway that officials say will ease commutes and take vehicles off local streets. The 18-mile, six-lane highway connecting Interstate 270 in Montgomery County with Interstate 95 in Prince George's County has long been championed by regional business groups, but faced stiff opposition from environmentalists as well as concerns over its cost. It finally won federal approval in May. In one lawsuit, filed in U.S. District Court in Washington, Environmental Defense and the Sierra Club claim the air quality analysis conducted by federal...

Their owners proudly proclaim that they reduce dependence on foreign oil — and save thousands of dollars on heating bills each year. Neighbors say that they create smoke so thick that children cannot play outside, and that it seeps into homes, irritating eyes and throats and leaving a foul stench. They have spawned a rash of lawsuits and local ordinances across the country. A report last year by the New York attorney general’s office found that they produce as much particle pollution in an hour as 45 cars or 2 heavy-duty diesel trucks. The devices, outdoor wood-fired boilers, originally invented...

Two environmental groups say they will sue to stop construction of the intercounty connector, arguing that building the highway would violate sections of the federal Clean Air Act. Environmental Defense and the Maryland chapter of the Sierra Club said the Washington region already fails to meet certain clean-air standards and that building the six-lane, 18-mile highway would increase pollution. The $2.4 billion intercounty connector would link Interstate 270 in Montgomery County with Interstate 95 in Prince George's County. "There are elementary schools and nursing centers close to the ICC, and people who live and work within several hundred yards of...

In New York City, air pollution levels have typically been monitored by inanimate objects, at more than a dozen locations around town. But in the South Bronx, from 2002 to 2005, air pollution monitors went mobile. They went to the playground, to the gritty sidewalks, even to the movies. A group of schoolchildren carried the monitors everywhere they went. The instruments, attached to the backpacks of children with asthma, allowed researchers at New York University to measure the pollution the children were exposed to, morning to night. The South Bronx is home to miles of expressways, more than a dozen...

Earth's protective ozone layer, which was notably thinning in 1980, may be fully recovered by mid-century, climate scientists said on Wednesday. Ozone in the stratosphere, outside the polar regions, stopped thinning in 1997, the scientists found after analyzing 25 years worth of observations. The ozone layer shields the planet from the sun's harmful ultraviolet radiation, but human-made chemicals -- notably the chlorofluorocarbons found in some refrigerants and aerosol propellants -- depleted this stratospheric ozone, causing the protective layer to get thinner. The scientists said the ozone layer's comeback is due in large part to compliance with an 1987 international agreement...

CHICAGO, July 12 — Biodiesel produced from soybeans produces more usable energy and reduces greenhouse gases more than corn-based ethanol, making it more deserving of subsidies, according to a study being published this month in The Proceedings of the National Academy of Sciences. The study, done by researchers at the University of Minnesota and at St. Olaf College in Northfield, Minn., points to the environmental benefits of the biodiesel over ethanol made from corn, stating that ethanol provides 25 percent more energy a gallon than is required for its production, while soybean biodiesel generates 93 percent more energy. The study’s...

BERLIN, June 28 — Germany, one of the biggest emitters of greenhouse gases in Europe, announced changes Wednesday that would allow increases in its emissions — a move that is expected to be challenged by the European Commission. The German cabinet decided to exclude the coal industry from the European Union's carbon trading program, under which companies must buy permits before they can release higher-than-mandated levels of carbon dioxide into the atmosphere. The move could persuade other countries to loosen their controls, critics said. Chancellor Angela Merkel, a Conservative, and her Social Democratic coalition partners agreed to cut Germany's emissions...

Truck, ship and cargo-handling equipment pollutants would be reduced 50 percent in five years under a clear air proposal for the Long Beach and Los Angeles harbors. Cleaner vehicles and shore-side electrical outlets so vessels can shut down diesel engines while dockside are key elements of the plan unveiled Wednesday. "This is an action plan, this is not a study. The days of yakkin' are coming to a screeching halt," harbor commission president S. David Freeman said. Proposals also include retrofitting and replacing cargo-handling equipment and locomotives. The plan, which now enters a 30-day public review period before approval by...

Cigarette smoking would be banned at city beaches and parks under a measure tentatively approved Monday by the city council. Sponsors said the measure will reduce litter and allow beachgoers to avoid secondhand smoke. "To me, this is a quality-of-life issue for San Diego," said Councilman Jim Madaffer, a co-sponsor. "This is an issue that is about public health and safety." The council unanimously approved the ban. A second vote is required before the measure becomes law. San Diego, whose miles of beaches are a major tourist draw, joins a handful of other California cities that have similar bans, including...

Ethanol stirred Wall Street last week when the second-largest ethanol producer went public, a sign that the corn-based fuel has become hot as gas prices soar. In its first day of trading, VeraSun Energy Corp.'s stock jumped 30% to $30 a share. Production capacity of ethanol in the U.S. has more than doubled since 1999, and the total number of ethanol plants has nearly doubled as well, to 97, with at least 30 more under construction. In April, Bill Gates, chairman of Microsoft Corp., bought a large stake in Pacific Ethanol Inc., which produces ethanol. Wal-Mart Stores Inc. recently said...

EXCLUSIVE Children exposed to high levels of city air pollution while in the womb are nearly three times more likely to have mental deficiencies than other kids, an explosive Columbia University study has found. The analysis compared the learning ability of 183 3-year-olds from Harlem, Washington Heights and the South Bronx with the level of pollutants they were exposed to before birth. The moms wore air monitors while they were pregnant, and the kids are being studied over a number of years. The study found that 42 kids exposed to the highest readings of polycyclic aromatic hydrocarbons in utero -...

ALBANY, Feb. 14 — As New York and other states grapple with the gradually tightening requirements of the Clean Air Act, the Environmental Protection Agency is refusing to turn over records detailing the levels of smog-causing compounds found in common household and industrial products like paints and varnishes. Such volatile organic compounds are not only significant contributors to smog, but they have also been linked to a variety of health problems, including the rising asthma rates in cities like New York and Los Angeles. After trying for two years to obtain the records, New York State sued the E.P.A. on...

Sean Penn, Snoop Dogg, Jamie Foxx and Danny Glover are among the thousands of mourners expected to turn out for the funeral of executed former gang leader Stanley 'Tookie' Williams early next week.

ROCHESTER, NY (2005-11-09) New Clean Car standards are being adopted in New York today. That's in an effort to reduce the amount of Global Warming pollutants that come from cars sold in the state. The Natural Resource Defense Council in New York is commending the Pataki administration for implementing the standards that were first adopted by California in 2004. Theo Spencer is the Senior Project Manager at the NRDC's Climate Center. He says the new standards require better pollution control on new vehicles. They target emmissions of pollutants that are said to contribute greatly to global warming: carbon dioxide, methane,...

LOS ANGELES (AP) - A California assemblywoman who suspects pollution contributed to the cancer she was diagnosed with last year announced plans Wednesday to seek an air cleanup bond that could cost the state between $2 billion and $5 billion dollars. The announcement by Assemblywoman Jenny Oropeza, D-Long Beach, followed a hearing in which lawmakers heard nearly three hours of testimony linking air pollution from California's ports, trucks and other shipping sources to deaths, childhood illnesses and even poor fetal development. The state Air Resources Board released a study earlier this month that found diesel emissions from the Los Angeles...

They might have been congratulated for their "green" efforts in an area of heavy air pollution. Instead a group of French cleaning ladies who organised a car-sharing scheme to get to work are being taken to court by a coach company which accuses them of "an act of unfair and parasitical competition". The women, who live in Moselle and work five days a week at EU offices in Luxembourg, are being taken to court by Transports Schiocchet Excursions, which runs a service along the route. It wants the women to be fined and their cars confiscated. Two years ago a...

Using unusually intemperate rhetoric even for a Democrat, firebrand Congresswoman Maxine Waters is blasting President Bush and Vice President Cheney over their conduct of the Iraq war, calling Bush "a liar" and Cheney "a thief." After attending a mock impeachment hearing two weeks ago staged by House Democrats, Rep. Waters told cheering onlookers, "Finally Congress has come alive and decided to take on this president in a real way." "The president is a liar," she continued. "Dick Cheney, the chief architect of the Big Lie, is not only a liar, he is a thief." She accused Cheney of helping his...
