Prescribed burns may help reduce US carbon footprint
The use of prescribed burns to manage Western forests may help the United States reduce its carbon footprint. A new study finds that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size. view more (2010-03-18)
Study highlights forest protected areas as a critical strategy for slowing climate change
A new study involving scientists from 13 different organizations, universities and research institutions states that forest protection offers one of the most effective, practical, and immediate strategies to combat climate change. view more (2010-03-16)
More maize ethanol may boost greenhouse gas emissions
In the March issue of BioScience, researchers present a sophisticated new analysis of the effects of boosting use of maize-derived ethanol on greenhouse gas emissions. view more (2010-03-11)
Waste could generate up to 7 percent of electricity in Spain
Researchers from the University of Zaragoza (UNIZAR) have calculated the energy and economic potential of urban solid waste, sludge from water treatment plants and livestock slurry for generating electricity in Spain. view more (2010-02-24)
Governments 'misjudging' scale of CO2 emissions
Policy makers in Europe and United States are markedly underestimating the changes needed to mitigate CO2 emission required to prevent dangerous climate change because they work in 'silos', according to pioneering research. view more (2010-02-22)
Orange peels, newspapers may lead to cheaper, cleaner ethanol fuel
Scientists may have just made the breakthrough of a lifetime, turning discarded fruit peels and other throwaways into cheap, clean fuel to power the world's vehicles. view more (2010-02-18)
Queen's researchers propose rethinking renewable energy strategy
Researchers at Queen's University suggest that policy makers examine greenhouse gas (GHG) emissions implications for energy infrastructure as fossil fuel sources must be rapidly replaced by windmills, solar panels and other sources of renewable energy. view more (2010-02-12)
Brown biologist solves mystery of tropical grasses' origin
Around 30 to 40 million years ago, grasses on Earth underwent an epic evolutionary upheaval. An assemblage capitalized on falling levels of atmospheric carbon dioxide by engineering an internal mechanism to concentrate the dwindling CO2 supply that, like a fuel-injection system in a car, could more efficiently convert sunlight and nutrients into... view more...

Black Carbon a Significant Factor in Melting of Himalayan Glaciers
The fact that glaciers in the Himalayan mountains are thinning is not disputed. However, few researchers have attempted to rigorously examine and quantify the causes. Lawrence Berkeley National Laboratory scientist Surabi Menon set out to isolate the impacts of the most commonly blamed culprit-greenhouse gases, such as carbon dioxide-from other... view more...

Ecologists discover forests are growing faster
Speed is not a word typically associated with trees; they can take centuries to grow. However, a new study to be published the week of Feb. 1 in the Proceedings of the National Academy of Sciences has found evidence that forests in the Eastern United States are growing faster than they have in the past 225 years. view more (2010-02-02)
Advanced engine-control system reduces biodiesel fuel consumption and emissions
Researchers from Purdue University and Cummins Inc. have developed an advanced "closed-loop control" approach for preventing diesel engines from emitting greater amounts of smog-causing nitrogen oxides when running on biodiesel fuels. view more (2010-01-26)
School classroom air may be more polluted with ultrafine particles than outdoor air
The air in some school classrooms may contain higher levels of extremely small particles of pollutants - easily inhaled deep into the lungs - than polluted outdoor air, scientists in Australia and Germany are reporting in an article in ACS' semi-monthly journal Environmental Science & Technology. view more (2010-01-21)
Study links springtime ozone increases above western North America to emissions from abroad
Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia. view more (2010-01-21)
Home is best for cardiac rehabilitation
Researchers from the NHS in Cornwall, the Peninsula Medical School, the Agency for Health Technology Assessment in Warsaw and the University of Birmingham have analysed 12 studies relating to cardiac rehabilitation and found no difference in health outcomes for patients who receive cardiac rehabilitation in a clinical setting or at home. view more (2010-01-20)
Urban 'green' spaces may contribute to global warming, UCI study finds
Dispelling the notion that urban "green" spaces help counteract greenhouse gas emissions, new research has found - in Southern California at least - that total emissions would be lower if lawns did not exist. view more (2010-01-20)
Much of the early methane rise can be attributed to the spreading of northern peatlands
The surprising increase in methane concentrations millennia ago, identified in continental glacier studies, has puzzled researchers for a long time. view more (2010-01-14)
You Say Offset, I Say Tax? Study Suggests Labels and Political Affiliation May Influence Preferences
Would you pay more for certain products to save the planet? That's the question behind the burgeoning carbon-offset industry - proponents pay more money for carbon-producing activities (such as flying), with the idea that the carbon emissions will be balanced out by funding for alternative energy sources. view more (2010-01-13)
Coral can recover from climate change damage
A study by the University of Exeter provides the first evidence that coral reefs can recover from the devastating effects of climate change. view more (2010-01-11)
School classroom air may be more polluted with ultrafine particles than outdoor air
The air in some school classrooms may contain higher levels of extremely small particles of pollutants - easily inhaled deep into the lungs - than polluted outdoor air. view more (2009-12-23)
Climate debate: What's warming us up? Human activity or Mother Nature?
A major analysis of the climate debate concludes that the majority of scientists agree that global warming is primarily man-made, although a vocal minority of skeptics is holding onto the idea that Mother Nature is the cause. view more (2009-12-23)
