Rare Microorganism That Produces Hydrogen May Be Key To Tomorrow's Hydrogen Economy
08 07 2008 An ancient organism from the pit of a collapsed volcano may hold the key to tomorrow's hydrogen economy. Scientists from across the world have formed a team to unlock the process refined by a billions-year old archaea. This novel hyperthermophilic archaea grows best at 80 to 82 degrees Celsius (176-180 Farenheit), close to the boiling point of water.

Process Used By Microbes To Make Greenhouse Gases Uncovered
08 07 2008 Researchers here now have a picture of a key molecule that lets microbes produce carbon dioxide and methane -- the two greenhouse gases associated with global warming. The findings relate to organisms called methanogens and are explained in the journal Proceedings of the National Academy of Sciences.

Study Shows Rise In Cornwall's Dolphin, Whale, And Porpoise Deaths
08 07 2008 A new study has revealed a disturbing rise in the number of whales, dolphins and porpoises found dead on Cornish beaches. The frequency of these mammals, collectively known as cetaceans, found stranded on beaches in Cornwall has increased with a sharp rise in the last eight years. After analyzing nearly 100 years of data, the researchers believe this could, in part, be due to more intensive fishing.

Short-circuiting of the overturning circulation in the Antarctic Circumpolar Current
02 04 2008 The oceanic overturning circulation has a central role in the Earth’s climate system and in biogeochemical cycling, as it transports heat, carbon and nutrients around the globe and regulates their storage in the deep ocean. Mixing processes in the Antarctic Circumpolar Current are key to this circulation, because they control the rate at which water sinking at high latitudes returns to the surface in the Southern Ocean. Yet estimates of the rates of these processes and of the upwelling that they induce are poorly constrained by observations. Here we take advantage of a natural tracer-release experiment—an injection of mantle helium from hydrothermal vents into the Circumpolar Current near Drake Passage—to measure the rates of mixing and upwelling in the current’s intermediate layers over a sector that spans nearly one-tenth of its circumpolar path. Dispersion of the tracer reveals rapid upwelling along density surfaces and intense mixing across density surfaces, both occurring at rates that are an order of magnitude greater than rates implicit in models of the average Southern Ocean overturning. These findings support the view that deep-water pathways along and across density surfaces intensify and intertwine as the Antarctic Circumpolar Current flows over complex ocean-floor topography, giving rise to a short circuit of the overturning circulation in these regions.

EurekAlert! is an online, global news service operated by AAAS, the science society. EurekAlert! provides a central place through which universities, medical centers, journals, government agencies, corporations and other organizations engaged in research can bring their news to the media.

Recovery of long-term climate measurements
09 07 2008 (The National Academies) Geostationary and polar-orbiting satellites provide information for both weather prediction and long-term climate records.

Iowa State researchers study ground cover to reduce impact of biomass harvest
09 07 2008 (Iowa State University) Iowa State University researchers are looking at ways to use ground cover, a living grass planted between the rows of corn, in production farming.

How intense will storms get? New model helps answer question
09 07 2008 (University of Michigan) A new mathematical model indicates that dust devils, water spouts, tornadoes, hurricanes and cyclones are all born of the same mechanism and will intensify as climate change warms the Earth's surface.

Adaptation Africa, June 2008
03 07 2008 Miscellaneous 2008 5 pp. (In English and French) This issue of the news and events bulletin from the Climate Change Adaptation in Africa (CCAA) program covers CCAA program news, Events, Calls for papers and proposals, Project news, and New resources.

Adaptation is...Protecting coastal communities in northern Morocco
03 07 2008 Miscellaneous 2008 International Development Research Centre (IDRC), Ottawa, Canada, 4 pp. This is one of a series of brief project profiles which provide insights into the kinds of challenges Africans face in adapting to climate change, and the strategies they are testing with research supported by the CCAA program. The profiles are based on interviews with CCAA staff and research team members, local officials, and community members involved in or affected by the research. Moroccos rural north east coast is increasingly vulnerable to the effects of climate change sea level rise, storm surges, and coastal flooding. An international research team led by Moroccos École nationale forestière dingénieurs is working in two neighbouring provinces to integrate a better understanding of climate change impacts within development plans and land use guidelines to meet the regions many competing needs.
