New research to run cars on flower power
Will the oilfields of the future be full of sunflowers? They could be if Leeds fuel and energy researchers succeed in producing hydrogen from sunflower oil. Hydrogen is seen as the fuel of the future - able to create electricity with no harmful emissions - to power everything from cars, portable generators to flashlights and even homes and... view more...

Stratospheric injections could help cool Earth, computer model shows
A two-pronged approach to stabilizing climate, with cuts in greenhouse gas emissions as well as injections of climate-cooling sulfates, could prove more effective than either approach used separately. view more (2006-09-15)
MIT: A quicker, easier way to make coal cleaner
Construction of new coal-fired power plants in the United States is in danger of coming to a standstill, partly due to the high cost of the requirement - whether existing or anticipated - to capture all emissions of carbon dioxide, an important greenhouse gas. view more (2008-11-18)
Historical crop samples link changes in wheat disease to air pollution
Scientists at Rothamsted Research in Harpenden (1) and the University of Reading have been able to recover DNA from crop diseases on wheat samples stored as part of a Victorian field experiment (2). Using this DNA, they have discovered how changes in air pollution over the last 160 years have affected fungal diseases on our wheat crops. view more (2005-04-11)
Global warming aided by drought, deforestation link
In the rainforests of equatorial Asia, a link between drought and deforestation is fueling global warming, finds an international study that includes a UC Irvine scientist. view more (2008-12-09)
Curbing coal emissions alone might avert climate danger, say researchers
An ongoing rise in atmospheric carbon dioxide from burning of fossil fuels might be kept below harmful levels if emissions from coal are phased out within the next few decades, say researchers. view more (2008-09-15)
Atmospheric Mercury Has Declined -- But Why?
The amount of gaseous mercury in the atmosphere has dropped sharply from its peak in the 1980s and has remained relatively constant since the mid 1990s. This welcome decline may result from control measures undertaken in western Europe and North America, but scientists who have just concluded a study of atmospheric mercury say they cannot... view more...

Methane gas levels begin to increase again
The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end a period of about a decade in which atmospheric levels of the potent greenhouse gas were essentially stable, according to a team led by MIT researchers. view more (2008-10-30)
Hotspots of mercury contamination identified in eastern North America
A US and Canadian research team surveying mercury contamination in fish and birds in the northeastern United States and southeastern Canada has identified five "hotspots" where concentrations of the element exceed those established for human or wildlife health. view more (2007-01-03)
Wildlife catastrophe if climate change continues
Evidence is mounting that climate change is adversely affecting wildlife, an international scientific conference on climate change will hear today. view more (2005-01-31)
Improved air quality during Beijing Olympics could inform pollution-curbing policies
The air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study. view more (2009-07-27)
'Green' research at Louisiana Tech results in new geopolymer concrete technology
Dr. Erez Allouche, assistant professor of civil engineering at Louisiana Tech University and associate director of the Trenchless Technology Center, is conducting innovative research on geopolymer concrete and providing ways to use a waste byproduct from coal fired power plants and help curb carbon dioxide emissions. view more (2009-09-30)
Report shows the power of US cities to mitigate climate change and steps they need to take to adapt
U.S. municipal governments are showing leadership by voluntarily accounting for and reducing greenhouse gas emissions resulting from their operations. view more (2009-07-08)
US fires release large amounts of carbon dioxide
Large-scale fires in a western or southeastern state can pump as much carbon dioxide into the atmosphere in a few weeks as the state's entire motor vehicle traffic does in a year. view more (2007-11-01)
Cassini cameras spot powerful new lightning storm on Saturn
Following the recent detection of Saturnian radio bursts by NASA's Cassini spacecraft that indicated a rare and powerful atmospheric storm, Cassini imaging scientists have spotted the storm in an unlikely fashion: they looked for it in the dark. view more (2006-02-15)
CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976] by mid-century if emissions are not dramatically... view more...

No laughing matter -- bacteria are releasing a serious greenhouse gas
Unlike carbon dioxide and methane, laughing gas has been largely ignored by world leaders as a worrying greenhouse gas. But nitrous oxide must be taken more seriously. view more (2008-03-31)
Cow power could generate electricity for millions
Converting livestock manure into a domestic renewable fuel source could generate enough electricity to meet up to three per cent of North America's entire consumption needs and lead to a significant reduction in greenhouse gas emissions (GHGs), according to US research published today. view more (2008-07-24)

Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weaken
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening. view more (2007-10-23)
