Princeton System Tracks Drought to Aid Disaster Relief

Drought is often the precursor to disaster, but getting leads on its stealthy approach through remote or war-torn areas can be so difficult that relief agencies sometimes have little time to react before a bad situation becomes a calamity.

Study Suggests Nation's Urban Forests Losing Ground

National results indicate that tree cover in urban areas of the United States is declining at a rate of about four million trees per year, according to a U.S. Forest Service study published recently in Urban Forestry & Urban Greening.

Biosphere Study at the University of Arizona

Scientists are preparing to launch a 10-year project to study water resources, gas exchange and carbon cycling in three man-made landscapes built in a half-acre laboratory at the University of Arizona’s Biosphere 2.

Burmese Pythons Reason for Mammal Habitat Decline in Everglades

Precipitous declines in formerly common mammals in Everglades National Park have been linked to the presence of invasive Burmese pythons, according to a study published today in the Proceedings of the National Academy of Sciences.

Ancient DNA Holds Clues to Climate Change Adaptation

Thirty-thousand-year-old bison bones discovered in permafrost at a Canadian goldmine are helping scientists unravel the mystery about how animals adapt to rapid environmental change.

How Seawater Could Corrode Nuclear Fuel

Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 -- and that was probably the best action to take at the time, says Professor Alexandra Navrotsky of the University of California, Davis.

Potato Company Pays EPA Penalty for Failing to Report Ammonia Release

Oregon Potato Company failed to report an anhydrous ammonia release at their facility in Warden, Wash., and will pay the U.S. Environmental Protection Agency (EPA) a $66,235 penalty.

Broadcast Study of Ocean Acidification to Date Helps Scientists Evaluate Effects on Marine Life

Might a penguin's next meal be affected by the exhaust from your tailpipe? The answer may be yes, when you add your exhaust fumes to the total amount of carbon dioxide lofted into the atmosphere by humans since the industrial revolution. One-third of that carbon dioxide is absorbed by the world's oceans, making them more acidic and affecting marine life.



Diverse Ecosystems are Crucial Climate Change Buffer

Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in in the world's drylands, according to a new landmark study.

Triad Mining Agrees to Resolve Clean Water Act Violations and Restore Affected Waterways in Indiana

The U.S. Environmental Protection Agency (EPA) and U.S. Department of Justice (DOJ) announced that Triad Mining Inc., the owner and operator of 31 surface mines in Appalachia and Indiana, has agreed to pay a penalty and restore affected waterways for failing to obtain the required Clean Water Act (CWA) permit for stream impacts caused by its surface mining operation in Indiana

Satellite Tracking Helps Russian Tanker Navigate Critical Sea Duck Habitat

On its way to deliver emergency fuel to Nome, Alaska, the Russian tanker Renda will move through an area used by wintering spectacled eiders, a federally threatened sea duck

Another Outbreak of Coral Disease Hits Reefs of Kaneohe Bay, Hawaii

The disease called acute Montipora White Syndrome (MWS) has reappeared and is again killing corals in Kaneohe Bay, Oʻahu.

What The Mining Debate is Missing

As mining is resurging in North America, debates across the continent over mines are simplified: “Do we prioritize jobs or the environment? Companies or communities?” These are worthy debates. Yet should the issue of mining really be reduced to “pro-con” statements?

Salt Water Alone Unlikely to Halt Burmese Python Invasion

Invasive Burmese python hatchlings from the Florida Everglades can withstand exposure to salt water long enough to potentially expand their range through ocean and estuarine environments, according to research in the latest issue of the Journal of Experimental Marine Biology and Ecology.

Weather Deserves Medal for Clean Air During 2008 Olympics

New research suggests that China's impressive feat of cutting Beijing's pollution up to 50 percent for the 2008 Summer Olympics had some help from Mother Nature.

Giant Weed Creates Threat to Our Nation's Ecosystems and Border Security

Weed control has become a matter of national security. Along U.S. southern coastal rivers, most particularly Texas’ Rio Grande, an invasive species of plant known as giant reed is encroaching on the water, overrunning international border access roads, and creating a dense cover for illegal activities.

Nitrogen from Humans Pollutes Remote Lakes for More Than a Century

Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of miles from the nearest city, industrial area or farm.

Will Antarctic Worms Warm to Changing Climate?

Researchers at the University of Delaware (UD) are examining tiny worms that inhabit the frigid sea off Antarctica to learn not only how these organisms adapt to the severe cold, but how they will survive as ocean temperatures increase.

Predicted Rise of Wildfires in Parts of Canada

Large forest regions in Canada are apparently about to experience rapid change. Based on models, scientists can now show that there are threshold values for wildfires just like there are for epidemics. Large areas of Canada are apparently approaching this threshold value and may in future exceed it due to climate change.

Certain Crops Show Higher Capacity for Carbon Fixation

Salt can have drastic effects on the growth and yield of horticultural crops; studies have estimated that salinity renders an about one-third of the world's irrigated land unsuitable for crop production.
