Reforestation Practices May Be Lagging Behind Climate Change

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.

Evidence Suggests La Nina Will Return This Winter

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.

Thawing Permafrost Could Release Vast Amounts of Carbon, Accelerating Climate Change

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

Study: Southern South American Wildfires Expected to Increase

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.

Growth of Cities Endangers Global Environment

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.

Is Investing in Green House Gas Auditing Companies Worth the Gamble?

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.

Higher-Resolution Microscope Provides Better Insight into Fuel Cell Operations

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.

EIA Reports 3.9-Percent Increase in U.S. Energy-Related CO2 Emissions in 2010

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.



Researcher: Texas Must Make Conservation Plans Now to bring Rangeland Back from Drought

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.

Wildlife Responds Three Times Faster to Climate Change Than Previously Predicted

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.

GHG Verification Instrument Finds Some Fudging in Countries Reported Emissions

The sobering study fount that Western Europe emits about twice as much HFC-23 as officially reported.

Research Shows Polar Ice Caps Can Recover From Warmer Climate Induced Melting

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.

Increased Tropical Forest Growth Could Release Carbon from the Soil

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.

Organic Photovoltaics: Solar Cells of the Future?

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.

Climate Change, Algae Lessen Lake Tahoe's Clarity

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.

Professor Presents Research About Effect of Dams on Climate to Congress

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.

Ethane Levels Yield Information About Changes in Greenhouse Gas Emissions

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.

Arctic Cruise Explores Changing Ocean Acidification

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.

Study: Late-’90s Arctic Ice Melt Caused Half by GHGs, Half by Normal Climate Conditions

These findings point to climate change and variability working together equally to accelerate the observed sea ice loss during the late 20th century.
