China's increasing air pollution has cut the light rainfall essential to the country's agriculture over the last 50 years, new research suggests.

Fish Farms Supply 50% of Global Harvest
September 8, 2009 11:45 AM - R. Greenway, ENN

Fish farms, once a fledgling industry, now account for 50 percent of the fish consumed globally, according to a new report by an international team of researchers. And while getting more efficient, it is putting strains on marine resources by consuming large amounts of feed made from wild fish harvested from the sea, the authors conclude. Their findings are published in the online edition of the Proceedings of the National Academy of Sciences.

Comment on "$20 Per Gallon"

Not often is a book written that can explain the intricacies and effects of economics, international relations, and the green movement, and how the three impact the sociology of our country and our world. However, in his recently released book “$20 Per Gallon,” Christopher Steiner does just that, and makes it interesting and funny to boot.

Methane Gas Could Increase From Oceanic Vents
September 6, 2009 08:03 AM - Roger Greenway, ENN

New MIT research by Denise Brehm, Department of Civil and Environmental Engineering, funded by the U.S. Department of Energy looked at the potential for a compound affect of warming global temperatures on the level of methane being released by oceanic vents. The premise is that rising global temperatures could be accompanied by melting permafrost in arctic regions and that this could initiate the release of underground methane into the atmosphere. Once released, that methane gas would speed up global warming by trapping the Earth's heat radiation about 20 times more efficiently than does the better-known greenhouse gas, carbon dioxide.

In the wake of a massive oil spill from the tanker Prestige, poisoned seagulls displayed smaller red spots on their beaks than healthy birds, according to a new study.

Climate-change technology risks 'catastrophic' outcome

Risky and unproven climate-changing technologies could have "catastrophic consequences" for the earth and humankind if used irresponsibly, according to a new report.

China Gradually Improves Environmental Transparency
September 2, 2009 10:01 AM - Ben Block, Worldwatch Institute

Very little is known about pollution levels throughout China, despite the country's worsening air quality and imperiled waterways. But now the Ministry of Environmental Protection authorized its Measures on Open Environmental Information, a new effort at public disclosure. The measure has been implemented for a year, and cities across China are slowly becoming more forthright with environmental information, according to a study by U.S. and Chinese environmental groups.

Our best guess about global warming may be wrong
September 2, 2009 06:40 AM - Moises Velasquez-Manoff, The Christian Science Monitor, Environmental Health News

Fifty-five million years ago, the world was a much warmer place. The poles were ice-free year-round. Palm trees grew in Alaska. Forests stretched right into the Arctic Circle. There, swamps like those in today’s southeastern United States hosted alligators, snakes, and giant tortoises. Scientists call this time in Earth’s history the Eocene, the dawn of the age of mammals. And climatologists have naturally taken a keen interest in how it began. They know that a dramatic spike in carbon dioxide associated with rapid climate change kicked off the epoch – called the "Paleocene-Eocene Thermal Maximum" (PETM). But what scientists don’t understand about the PETM may hold the most relevant lessons for where the world’s climate is headed today.
