The arrival of El Niño, which every three to seven years boosts temperatures and cuts rainfall, doubles the risk of civil wars across 90 affected tropical countries, and may help account for a fifth of worldwide conflicts during the past half-century, say the authors.
A University of Alberta study is sounding a warning about forestry practices in North America, claiming that climate change is already rendering established planting guidelines obsolete.
Less than 2 percent of the October-July periods since 1895 have been drier than they are currently for all of Texas and many parts of New Mexico. These areas experienced either their driest or second driest October-July periods in the last 117 years. Less than six percent of the October-July periods have been drier than current conditions in southeastern Arizona.
Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates
A new University of Colorado - Boulder study indicates a major climate oscillation in the Southern Hemisphere, expected to intensify in the coming decades, will likely cause increased wildfire activity in the southern half of South America.
The explosive growth of cities worldwide over the next two decades poses significant risks to people and the global environment, according to a meta-analysis published today in Plos One.
Greenhouse gas auditing is predicted to be one of the next biggest global industries as more countries are attempting cut down their carbon footprint and have passed laws requiring corporations to dramatically reduce their levels of pollution. However, serious questions have been raised as to how profitable this industry will be, and whether it is even worth investing in at such an early stage.

A novel microscopy method at the Department of Energy’s Oak Ridge National Laboratory is helping scientists probe the reactions that limit widespread deployment of fuel cell technologies.
U.S. carbon dioxide emissions from the consumption of fossil fuels were 5,638 million metric tons carbon dioxide (MMTCO2) in 2010, an increase of 3.9 percent from the 2009 level.
As a blistering drought continues to plague huge portions of Texas, a Texas Tech University researcher says that even now in the midst of the fight, it’s time to plan ahead and logically plot a path for pulling more than 90 million acres of valuable rangeland back from the brink.
New research by scientists in the Department of Biology at the University of York shows that species have responded to climate change up to three times faster than previously appreciated. These results are published in the latest issue of the leading scientific journal Science.
The sobering study fount that Western Europe emits about twice as much HFC-23 as officially reported.
A growing body of recent research indicates that, in Earth's warming climate, there is no "tipping point," or threshold warm temperature, beyond which polar sea ice cannot recover if temperatures come back down. New University of Washington research indicates that even if Earth warmed enough to melt all polar sea ice, the ice could recover if the planet cooled again.
A new study shows that as climate change enhances tree growth in tropical forests, the resulting increase in litterfall could stimulate soil micro-organisms leading to a release of stored soil carbon.
Undergraduate researcher Safatul Islam is a member of a team in the College of Optical Sciences investigating organic photovoltaics, which can lead to improved electronics.
Lake Tahoe clarity dropped in 2010, but the rate of decline in clarity over the past decade remains slower compared with previous decades, according to UC Davis scientists who have monitored the lake for more than 40 years.
As the U.S. government makes decisions on high-profile environmental issues, Faisal Hossain’s influence on those decisions is growing—attesting to the fact that a researcher at a mid-size university in a rural area can have a powerful national, even international, impact.
Recent data from NSF-funded research in both Greenland and Antarctica demonstrate that fossil-fuel related emissions of both methane and ethane, two of the most abundant hydrocarbons in the atmosphere, declined at the end of the twentieth century, according to a paper published Thursday in the journal Nature.
Scientists from the U.S. Geological Survey will embark on a research cruise to the Arctic Ocean beginning today to collect water samples and other data to determine trends in ocean acidification from the least explored ocean in the world.
These findings point to climate change and variability working together equally to accelerate the observed sea ice loss during the late 20th century.
