Geoengineering Being Discussed in Washington
November 6, 2009 06:47 AM - Roger Greenway, ENN

Dr. Ken Caldeira, of the Carnegie Institution of Washington provided a balanced look at the potential benefits and also the costs and possible harm that geoengineering techniques could offer in our quest to find a “Magic Bullet” to counter global warming. Can global warming be mitigated by a technological fix such as injecting light-blocking particles into the atmosphere or chemically “scrubbing” excess greenhouse gases from the atmosphere? Department of Global Ecology scientist Ken Caldeira addressed this question in his testimony to the U.S. House of Representatives Committee on Science and Technology in a hearing titled “Geoengineering: Assessing the Implications of Large-Scale Climate Intervention” on November 5, 2009.

Washington, Stop Dithering, US Goals on Climate Urgently Needed
November 5, 2009 05:47 AM - Ben Jervey, Triple Pundit

As the last round of "intersessional" climate talks before Copenhagen opened today in Barcelona, all eyes were looking in the same direction they were when we left Bangkok three weeks earlier: at the United States. Without American numbers on mitigation (or emissions reductions) and finance (for developing nations to build their own clean energy economies, and also to adapt to the impacts of climate change), any real forward progress in the talks is just about impossible.

Degraded Habitats Push More Species to Extinction
November 4, 2009 10:17 AM - Ben Block, Worldwatch Institute

The latest global assessment of biodiversity ruled yesterday that an additional 11 species are either fully extinct or extinct outside of captivity. As climate change, invasive species, and habitat destruction place greater pressure on wildlife, more species are disappearing at rates faster than conservationists can react to ensure the species' survival.

Water Evaporates from the Climate Change Negotiating Text

Negotiators meeting this week in Barcelona for the last round of UN climate talks before a big conference in Copenhagen next month are working on negotiating texts that have no reference to water and its management as tools for climate change adaptation.

Ethiopian Rift Shows How Continents Can Split, Create New Ocean
November 4, 2009 08:10 AM - Roger Greenway, ENN

A new study reported by the Addis Ababa University in Ethiopia and the University of Rochester sheds light on how the continents move, and oceans are created. In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial. Now, scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world's oceans, and the rift is indeed likely the beginning of a new sea.

Margaret Thatcher, Lyndon Johnson were Right!

President Lyndon Johnson and British Prime Minister Margaret Thatcher made stark warnings about global warming decades ago, but convincing evidence for action only amassed in recent years, experts say. A 190-nation U.N. conference in Copenhagen in December is due to agree a new U.N. pact to curb greenhouse gas emissions to slow a rise in temperatures to prevent floods, droughts, wildfires or rising sea levels.

Africa Boycotts U.N. Climate Talks, Demands CO2 Cuts

BARCELONA, Spain - African nations boycotted U.N. climate talks on Tuesday in a protest to urge rich countries to set deeper 2020 cuts in greenhouse gas emissions. "Africa believes that the other groups are not taking talks seriously enough, not urgently enough," said Kabeya Tshikuku, of the Democratic Republic of Congo delegation.

Ohio State Glaciologist Team Gets Important Ice Cores in Andes
November 3, 2009 06:46 AM - Roger Greenway, ENN

Ice cores are important tools to identify Earth’s past climate. They enable us to peer back in time to identify species of insects trapped in ice as well as isotopes oxygen and dust particles that were deposited at various time in the past. The ratio of oxygen isotopes in the ice allows researchers to determine whether temperatures were warmer or cooler when the snow that eventually turned to ice was deposited on the glacier. The dust content gives scientists clues about the rate of precipitation at the site. The thicker the core (longer cores) the longer into the past we can see.

BP, GE to build 'clean coal' plant in Southern California

Oil giants BP and General Electric Co. announced plans recently to collaborate on a 250-megawatt coal-fired power plant that would employ integrated gasification technology and carbon dioxide capture in Southern California.

Sea Slime Killing U.S. Seabirds
November 2, 2009 12:35 PM - National Geographic News

Hundreds of birds are washing up on the shores of the U.S. Pacific Northwest coated with a foamy sea slime, scientists say. Research suggests that recently, the blooms are larger, lasting longer, and happening with greater frequency.
