About 55 million years ago, the Earth burped up a massive release of carbon dioxide into the atmosphere – an amount equivalent to burning all the petroleum and other fossil fuels that exist today.
Since 1998, climate scientists have attempted to reconstruct global annual temperature over the last millennium using natural proxies such as tree rings and ice cores. However, a new study finds substantial uncertainty in these reconstructions.
As one of the planet’s largest single carbon absorbers, the ocean takes up roughly one-third of all human carbon emissions, reducing atmospheric carbon dioxide and its associated global changes.But whether the ocean can continue mopping up human-produced carbon at the same rate is still up in the air.
Which U.S. metro region is most likely to come out of the next recession, natural disaster or other regional “shock” relatively unscathed? Rochester, Minn. A little more battered might be College Station-Bryan, Texas.
The National Science Foundation has awarded a five-year, $10 million grant to Florida State University and the University of Florida to coordinate 92 institutions in 45 states working to digitize the nation’s biological collections.
Chemically bonded phosphate ceramics create a passivation layer that stops corrosion and is protected by a tough ceramic outer layer. These compounds protect metal from corrosion better than other options, such as polymer paints, and are less expensive than using stainless steel.

Originally proposed as a small gathering of EVTV viewers, the concept grew into more of a convention within two weeks of the announcement due to the number of early registrants.
Researchers have discovered a way to capture and harness energy transmitted by such sources as radio and television transmitters, cell phone networks and satellite communications systems.
The prospect of rising temperatures in Iowa and the Midwest is predicted to lead to a dramatic decline in corn yield. With a $5 million grant from the U.S. Department of Agriculture, Iowa State University researchers are looking to develop a corn variety that maintains the region’s high yields even as temperatures rise.
Tiny metallic particles produced by University of Adelaide chemistry researchers are bringing new hope for the production of cheap, efficient and clean hydrogen energy.
California's Butte College is the first college in the history of the United States to go 'grid positive,' meaning that it will generate more electricity from its solar arrays than it consumes and will deliver power back to the electric grid.
The "Economic Impacts of Restoration Calculator for Oregon Counties" helps restoration practitioners better forecast the economic impacts of field-based restoration spending.
Development of disease resistance among Chesapeake Bay oysters calls for a shift in oyster-restoration strategies within the Bay and its tributaries.
The U.S. Environmental Protection Agency has awarded nearly $3 million to better understand how the liver responds to environmental toxicants. Four academic institutions, including Virginia Polytechnic Institute and State University, will develop ways to enhance what society knows about environmental contaminants and the liver, the body’s waste treatment organ.
The study found that, overall, composition of a plant community is a weak predictor of the composition of a bee community, which may seem counterintuitive at first, said USGS scientist and study lead Ralph Grundel
How does the power output from solar panels fluctuate when the clouds roll in? And can researchers predict these fluctuations? UC San Diego researchers have found the answer to these questions.
During the last space shuttle flight, scheduled for July 8, 2011, astronauts will test a new method for recycling "used" water. Water is essential for life, and having access to water beyond Earth will be a major obstacle for future space explorers.
The award honors Genomatica's affect on the production of major industrial chemicals – those made and sold in billions of pounds per year – with better economics and a smaller environmental footprint, using biological organisms and renewable feedstocks.
Climate change disasters, such as the melting of the Greenland ice sheet, dieback of the Amazon rainforest, or collapse of the Atlantic overturning circulation, could be predicted argues a University of Exeter researcher.
A team of students from the Bourns College of Engineering at the University of California, Riverside, have been selected for a $15,000 EPA grant to develop a system that could cut electricity bills up to 16 percent by using heat from the sun and attic to operate a clothes dryer.
