NASA's first spacecraft dedicated to studying carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth's climate, has arrived at Vandenberg Air Force Base, Calif., to begin final launch preparations. The Orbiting Carbon Observatory arrived Nov. 11 at its launch site on California's central coast after completing a cross-country trip by truck from its manufacturer, Orbital Sciences Corp. in Dulles, Va. The spacecraft left Orbital on Nov. 8. After final tests, the...

U.S. scientists say they've determined earthworms can change the chemical nature of the carbon in North American forest litter and soils. Purdue University scientists, along with researchers from the Smithsonian Institution and Johns Hopkins University, studied the effect of earthworms on forest chemistry by comparing carbon composition in forests that vary in earthworm activity. They found forests with greater numbers of invasive earthworms tend to have litter and soil organic matter...

In one of the first comparisons of its kind, researchers have demonstrated that wetlands in tropical areas are able to absorb and hold onto about 80 percent more carbon than can wetlands in temperate zones. The scientists extracted soil cores from wetlands in Costa Rica and in Ohio and analyzed the contents of the sediment from the past 40 years. Based on their analysis, they estimated that the tropical wetland accumulated a little over 1 ton of carbon per acre per year, and the temperate...

By Festa, David ". . . Ocean surface temperatures worldwide have risen on average 0.9[degrees]F, and ocean waters in many tropical regions have risen by almost 2[degrees] over the past century. This is 30 times the amount of heat that has been added to the atmosphere. . . ." MARINE BIOLOGIST Chris Rader recalls childhood summers when his father, Environmental Defense scientist Doug Rader, would take him diving in the Virgin Islands: "Schools of butterfly fish and Queen angelfish would swim...

Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries. However, these old growth forests around the world are not protected by international treaties and have been considered of no significance in the national "carbon budgets" as outlined in the Kyoto Protocol. That perspective was...

EESTech and Tianjin Dagang Huashi Power Generation have signed a memorandum of understanding to establish a carbon capture and storage project in China using EESTech's carbon management and storage technology. Dagang will use one of its two 330MW power units to demonstrate the capture of CO2 from its flue gas stream and then transport the CO2 for geosequestration and enhanced oil recovery. The project is expected to showcase the development of the CO2 capture project that can be profiled...

The Anviron Holding Company (Pinksheets:ANVH) ("Anviron"), a manufacturer and marketer of "Clean & Green" products and technology, announced today that the company has released a white paper on use of the company's NuSoil Technology to the government of Thailand. The paper focuses on the use of NuSoil products in mine reclamation projects and the carbon credit market advantages of using these technologies. NuSoil is a non-polluting organic fertilizer technology that is having an...

A new Australian study of "green carbon" and its role in climate change suggests that untouched natural forests store three times more carbon dioxide than previously estimated and 60 percent more than plantation forests. Green carbon occurs in natural forests, brown carbon is found in industrialized forests or plantations, grey carbon in fossil fuels and blue carbon in oceans. The role of untouched forests, and their biomass of green carbon, had been underestimated in the fight against global...

By Johann Hari If al-Qa'ida was unleashing this weather of mass destruction, we would do anything to stop them Imagine if tomorrow the CIA and MI6 discover that Osama bin Laden has invented an incredible new weapon. This machine - stashed away in some dusty Afghan cave - doubles the intensity of hurricanes, causing them to drown a US city and kill nearly 2,000 people. It turns Spain and Australia dry in the worst droughts on record. It makes the oceans acidic, killing essential parts of...

A seasonal bloom of ocean plankton is pulling more carbon dioxide than previously thought from the atmosphere into the Atlantic Ocean, U.S. researchers said. The bloom -- nurtured by the Amazon River -- may be enough to turn the tropical Atlantic from a net source of atmospheric carbon into a net carbon sink that removes carbon dioxide from the atmosphere, New Scientist reported. Ajit Subramaniam, an oceanographer at Lamont-Doherty Earth Observatory in Palisades, N.Y., and his colleagues...
