'Green' roofs may help put lid on global warming
"Green" roofs, those increasingly popular urban rooftops covered with plants, could help fight global warming, scientists in Michigan are reporting. view more (2009-09-24)
LSU, Yale team study agricultural impact on Mississippi River
According to a study published in "Nature" by researchers at LSU and Yale University, farming has significantly changed the hydrology and chemistry of the Mississippi River, injecting more carbon dioxide into the river and raising river discharge during the past 50 years. view more (2008-01-24)
Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science. view more (2007-06-25)
Increased carbon dioxide in atmosphere linked to decreased soil organic matter
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander - increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil -- but it didn't. view more (2008-03-12)
Smithsonian scientists report new carbon dioxide study
Researchers at the Smithsonian Environmental Research Center report the results of a six-year experiment in which doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil. view more (2007-03-13)
Planet-sized solutions for global warming: International experts evaluate the options
Big ideas for reducing the impacts of climate change are being evaluated by an international line-up of leading scientists from the US, mainland Europe and the UK at a symposium in Cambridge this week. The scientists are coming together to evaluate which large-scale bio-engineering, geo-engineering and chemical engineering ideas to combat global... view more... (2004-01-05)
North Atlantic slows on the uptake of CO2
Further evidence for the decline of the oceans' historical role as an important sink for atmospheric carbon dioxide is supplied by new research by environmental scientists from the University of East Anglia. view more (2007-10-23)
Greenhouse gas/temperature feedback mechanism may raise warming beyond previous estimates
A team of European scientists reports that climate change estimates for the next century may have substantially underestimated the potential magnitude of global warming. view more (2006-05-22)
New materials can selectively capture carbon dioxide, UCLA chemists report
UCLA chemists report a major advance in reducing heat-trapping carbon dioxide emissions in the Feb. 15 issue of the journal Science. view more (2008-02-15)
Last time carbon dioxide levels were this high: 15 million years ago, scientists report
You would have to go back at least 15 million years to find carbon dioxide levels on Earth as high as they are today, a UCLA scientist and colleagues report Oct. 8 in the online edition of the journal Science. view more (2009-10-09)
Learning to trade in carbon dioxide
"You have to be well prepared to enter the emissions trading arena. Otherwise you'll run the same financial risks as on a conventional stock exchange," declares Franzjosef Schafhausen of the German ministry for the environment, who heads the working group on the national climate change program. Poor awareness of the implications of... view more... (2003-12-01)
Ocean's 'twilight zone' may be a key to understanding climate change
A major study sheds new light on the role of carbon dioxide once it's transported to the oceans' depths. The research indicates that instead of sinking, carbon dioxide is often consumed by animals and bacteria and recycled in the "twilight zone," a dimly lit area 100 to 1,000 meters below the surface. view more (2007-04-30)
Climate protocol may save Amazon region
If Brazil gets a climate protocol, like the Kyoto Protocol for the rich countries, it will be possible to create an incentive for the country to reduce the deforestation of the Amazon region. The Kyoto Protocol targets a reduction of emissions of carbon dioxide and greenhouse gases. In a new study, Martin Persson, in collaboration with Christian... view more... (2004-05-28)
Canada's new government invests in carbon capture research delivering real results on greenhouse gas
The Honourable Gary Lunn, Minister of Natural Resources, along with partners from Innoventures Canada (I-CAN), today announced funding for a project related to the initial development of the I-CAN Centre for the Conversion of Carbon Dioxide (CO2), at the Economic Club in Calgary. view more (2007-03-13)
NASA study illustrates how global peak oil could impact climate
The burning of fossil fuels -- notably coal, oil and gas -- has accounted for about 80 percent of the rise of atmospheric carbon dioxide since the pre-industrial era. Now, NASA researchers have identified feasible emission scenarios that could keep carbon dioxide below levels that some scientists have called dangerous for climate. view more (2008-09-11)
HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at Earth Systems Processes, a multidisciplinary... view more... (2001-06-21)
Southern Ocean could slow global warming
The Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought, according to new research. view more (2006-12-06)
Coral reefs may start dissolving when atmospheric CO2 doubles
Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. view more (2009-03-10)
Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that... view more... (2007-09-27)
New earth observation centres announced
Two new centres which will use satellites and models to help forecast earthquakes and the effects of carbon in climate change were announced (Wednesday 17 October) by Lord Sainsbury, Science & Innovation Minister. Said Lord Sainsbury, " I am delighted to announce that the Natural Environment Research Council is establishing two new... view more... (2001-10-19)
