Geoengineering climate requires more research, cautious consideration and appropriate restrictions
Geoengineering - deliberately manipulating physical, chemical, or biological aspects of the Earth system to confront climate change - could contribute to a comprehensive risk management strategy to slow climate change but could also create considerable new risks. view more (2009-07-22)
Storing carbon dioxide below ground may prevent polluting above
A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock. view more (2007-02-12)
Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new assessment in the September 2008 issue of BioScience. view more (2008-09-02)
Energy Lab Sets Aggressive Greenhouse Gas Reduction Goal
The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has pledged to reduce its greenhouse gas emissions by 75 percent from 2005 to 2009. view more (2007-12-06)
Benefits of eating seafood outweigh risks
Though some species of fish around the world's are likely to be contaminated with mercury, PCBs and other toxins, the benefits of eating seafood continue to outweigh the risks. view more (2006-02-27)
First extrasolar planets, now extrasolar moons
ESA is now planning a mission that can detect moons around planets outside our Solar System, those orbiting other stars! Everyone knows our Moon: lovers stare at it, wolves howl at it, and ESA recently sent SMART-1 to study it. But there are over a hundred other moons in our Solar System, each a world in its own right. A moon is a natural body... view more... (2003-10-09)
USC study finds big air pollution impacts on local communities
Heavy traffic corridors in the cities of Long Beach and Riverside are responsible for a significant proportion of preventable childhood asthma, and the true impact of air pollution and ship emissions on the disease has likely been underestimated, according to researchers at the University of Southern California (USC). view more (2009-11-05)
EU research drive to reduce air pollution from traffic
Today the EU signed an agreement with the USA, Japan and China to address air pollution from transport. Signed during a conference in Milan, the accord will allow for joint research on emissions and vehicle testing, and it foresees the creation of a common scientific platform to measure and benchmark air pollution from traffic. The joint effort... view more... (2003-12-10)
New sensor system improves detection of lead, heavy metals
The Department of Energy's Pacific Northwest National Laboratory has developed a new rapid, portable and inexpensive detection system that identifies personal exposures to toxic lead and other dangerous heavy metals. view more (2008-02-13)
Have you run out of energy?
Imagine having your own annual greenhouse gas allowance which you 'spend' each time you fill up with petrol or pay an electric or gas bill. It sounds like a scene from a futuristic movie, but this scenario could really happen in the next few years according to researchers at the UK's Tyndall Centre for Climate Change Prediction. view more (2004-09-20)
Emission choices lead to starkly different futures for Northeast agriculture, says CU expert at briefing
Farmers will be the first to feel the heat from global warming as they grapple with new and aggressive crop pests, summer heat stress and other sobering challenges that could strain family farms to the limit, warns David Wolfe, a Cornell expert on the effects of climate change on agriculture. view more (2007-07-12)
Potent greenhouse gas more prevalent in atmosphere than previously assumed
A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego. view more (2008-10-24)
Too little attention is paid to the side effects of emission-limiting measures
With measures aimed at reducing the emission of pollutants such as ammonia, policy makers pay too little attention to the consequences for the emission of other substances. This is revealed in a computer model constructed by Corjan Brink from Wageningen University during his doctoral research. For example, the model shows that reducing the amount... view more...

Pitt professor says harmful byproducts of fossil fuels could be higher in urban areas
Nitrogen oxides, the noxious byproduct of burning fossil fuels that can return to Earth in rain and snow as harmful nitrate, could taint urban water supplies and roadside waterways more than scientists and regulators realize. view more (2007-10-23)
Emission Reduction Assumptions for Carbon Dioxide Overly Optimistic, Study Says
Reducing global emissions of carbon dioxide (CO2) over the coming century will be more challenging than society has been led to believe, according to a research commentary appearing this week in the journal Nature. view more (2008-04-03)
First plant producing biodiesel
Bionor Transformaci'łn, S.A. has inaugurated the first plant in the Basque Country for the production of a biodiesel fuel , based on used vegetable oil and other renewable materials. The plant will produce 20,000 tons of biodiesel fuel a year. BIONOR Transformaci'łn, S.A. is a company made up of AZTI, the Basque Energy Corporation, by companies... view more... (2003-05-23)
More research needed to make good on biofuel promise, experts say
While cellulosic biofuels derived from grasses, crop residues and inedible plant parts have real potential to be more efficient and environmentally friendly than grain-based biofuels like corn ethanol, more research and science-based policies are needed to reap these benefits, says an international group of experts. view more (2008-10-06)
The Green (and blue, red, and white) lights of the future
A revolution in energy-efficient, environmentally-sound, and powerfully-flexible lighting is coming to businesses and homes, according to a paper in latest special energy issue of Optics Express, the Optical Society's (OSA) open-access journal. view more (2008-12-17)
Focus on methane to save the planet
SMALL print in the Kyoto Protocol threatens to make global warming more severe than it need be over the next 10 years or so. An obscure rule is discouraging countries from applying cheap technologies that could dramatically curb global warming in the short term, warns a British climate scientist.... view more...

Invisible gases form most organic haze in urban, rural areas
A new study involving the University of Colorado at Boulder shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world. view more (2007-07-10)
