Study rules out ancient 'bursts' of methane from seafloor deposits
A dramatic increase about 12,000 years ago in levels of atmospheric methane, a potent greenhouse gas, was most likely caused by higher emissions from tropical wetlands or from plant production, rather than a release from seafloor methane deposits.   view more (2006-08-25)

Arctic spring comes weeks earlier than a decade ago
In the Earth's cold and icy far north, the harsh winters are giving way to spring weeks earlier than they did just a decade ago, researchers have reported in the June 19th issue of Current Biology, published by Cell Press.   view more (2007-06-19)

Climate scientists spotlight Arctic warming, plight of polar bears
A climate scientist at the University of Chicago and 30 of her colleagues from across North America and Europe are urging the U.S. Fish and Wildlife Service to list the polar bear as a threatened species because global warming is melting its sea-ice habitat.   view more (2006-06-19)

Changes to land cover may enhance global warming in Amazon, reduce it in midlatitudes
New simulations of 21st-century climate show that human-produced changes in land cover could produce additional warming in the Amazon region comparable to that caused by greenhouse gases, while counteracting greenhouse warming by 25% to 50% in some midlatitude areas.   view more (2005-12-09)

Yale journal examines the global impact of cities
The global impact of cities is the focus of cutting-edge research in a special issue of Yale's Journal of Industrial Ecology.   view more (2007-06-18)

Greenhouse gas bubbling from melting permafrost feeds climate warming
A study co-authored by a Florida State University scientist and published in the Sept. 7 issue of the journal Nature has found that as the permafrost melts in North Siberia due to climate change, carbon sequestered and buried there since the Pleistocene era is bubbling up to the surface of Siberian... view more (2006-09-07)

Scientists use new techniques to narrow down impact of global warming on specific regions
People will soon be able to find out how vulnerable their own local area is to global warming, thanks to new techniques developed by scientists.   view more (2005-11-28)

Journal details how global warming will affect the world's fisheries
Watching the ebb and flow of populations of fisheries around the world can provide some insight into understanding the effects of global warming on our planet, according to a group of researchers writing in the summer 2007 issue of Natural Resource Modeling.   view more (2007-05-17)

Extinctions linked to climate change
A new report that links global warming to the recent extinction of dozens of amphibian species in tropical America is more evidence of a large phenomena that may affect broad regions, many animal species and ultimately humans.   view more (2006-01-12)

North Atlantic warming tied to natural variability; but global warming may be at play elsewhere
A Duke University-led analysis of available records shows that while the North Atlantic Ocean's surface waters warmed in the 50 years between 1950 and 2000, the change was not uniform. In fact, the subpolar regions cooled at the same time that subtropical and tropical waters warmed.   view more (2008-01-04)

Geoengineering could slow down the global water cycle
As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures.   view more (2008-05-28)

Adaptation to global climate change is an essential response to a warming planet
Temperatures are rising on Earth, which is heating up the debate over global warming and the future of our planet, but what may be needed most to combat global warming is a greater focus on adapting to our changing planet, says a team of science policy experts writing in this week's Nature magazine.   view more (2007-02-08)

Establishing a connection between global warming and hurricane intensity
Climate change is affecting the intensity of Atlantic hurricanes, and hurricane damage will likely continue to increase because of greenhouse warming, according to a new study.   view more (2006-08-16)

Dirty snow may warm Arctic as much as greenhouse gases
The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism - dirty snow - can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases.   view more (2007-06-07)

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)

Miniature lab ice spikes may hold clues to warming impacts on glaciers
Tiny lab versions of 12-foot tall snow spikes that form naturally on some high mountain glaciers may someday help scientists mitigate the effects of global warming in the Andes, according to a University of Colorado at Boulder professor.   view more (2007-03-06)

Level of important greenhouse gas has stopped growing
Scientists at UC Irvine have determined that levels of atmospheric methane - an influential greenhouse gas - have stayed nearly flat for the past seven years, which follows a rise that spanned at least two decades.   view more (2006-11-21)

Ocean warming on the rise
Increased scientific confidence that ocean observations are accurately reflecting rising global temperatures is central to new Australian research published today in the journal, Nature.   view more (2008-06-19)

Annual plants may cope with global warming better than long-living species
Countering Charles Darwin's view that evolution occurs gradually, UC Irvine scientists have discovered that plants with short life cycles can evolutionally adapt in just a few years to climate change.   view more (2007-01-09)

Climate warming and habitat loss threaten British Butterfly survival
Because butterflies are cold blooded, their growth and development are closely dependent on the weather and climate. When climates change insects can either shift breeding distributions to track it, stay put and adapt, or die out. Since the 1970s, climate warming in Britain has seen almost 20% of... view more (2003-06-05)

Black carbon pollution emerges as major player in global warming
Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal... view more (2008-03-24)

Rapid warming caused vegetation changes
Fossil leaves buried 55 million years ago show, for the first time, that rapid warming not only changed animal communities, but plant communities as well; and that the ancient warm spell may be representative of global warming's effects in Earth's future.   view more (2005-11-14)

Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet.   view more (2007-06-01)

Marine Algae A Weapon Against Global Warming?
"Parforce" an EU-funded research project has discovered a new link between marine algae and climate change. Researchers working on the project found out that iodine vapours, released from algae or plankton, condense over oceans to form aerosols . These aerosols, which tend to counter "global... view more (2002-07-18)
