• How Safe is the U.S. Food Supply ?

    Jill Kohl was a healthy young woman in early August 2006. A marathon runner, the 2000 Wahlert High School graduate was attending graduate school in Milwaukee. She ran regularly and was careful to eat a diet of healthy foods. But just a few days after eating a spinach salad late that month, Kohl started to experience flu-like symptoms. >> Read the Full Article
  • Black carbon pollution emerges as major player in global warming

    Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal Nature Geoscience. Scripps Institution of Oceanography at UC San Diego atmospheric scientist V. Ramanathan and University of Iowa chemical engineer Greg Carmichael, said that soot and other forms of black carbon could have as much as 60 percent of the current global warming effect of carbon dioxide, more than that of any greenhouse gas besides CO2. >> Read the Full Article
  • Coral's Addiction to 'Junk Food'

    Over two hundred million humans depend for their subsistence on the fact that coral has an addiction to ‘junk food’ - and orders its partners, the symbiotic algae, to make it. This curious arrangement is one of Nature’s most delicate and complex partnerships – a collaboration now facing grave threats from climate change. >> Read the Full Article
  • Japan welcomes spring with first cherry blossoms

    Cherry blossoms flowered in Tokyo and two other prefectures in Japan, the first of this season in designated observation areas across the country, the Japan Meteorological Agency said on Saturday. The emergence of the delicate, pale pink blooms is something of a national obsession, the focus of close media attention during the month or so it takes for the "cherry front" to move from south to north. >> Read the Full Article
  • Flood in Kazakhstan leaves thousands without water

    ALMATY (Reuters) - Thousands of people were left without fresh water in Kazakhstan on Monday after a major flood disrupted water supplies in the southwest of the Central Asian state, the Emergencies Ministry said. Spring flooding is a recurring problem across Central Asia but an abrupt rise in temperatures following weeks of severe cold has exacerbated the problem this year. >> Read the Full Article
  • Countering an approaching water crisis

    As growing demand for clean water stretches even the resources of the world's largest industrialized nations, scientists and engineers are turning to new technology and novel ideas to find solutions. Mark Shannon of the University of Illinois at Urbana-Champaign joined a slate of world leaders in water resource research to address this crisis in a review paper in the March 20, 2008, issue of Nature. >> Read the Full Article
  • U.S. Environmental Groups Divided on “Clean Coal”

    At a Senate press conference held last week to urge national action on climate change policy, 16 major U.S. environmental organizations shared the stage in solidarity. But while it appears the nation's green groups are united in the fight against global warming, they remain divided on which technologies would best create a carbon-free economy. This division may cause major roadblocks as Congress prepares to debate several climate change policies that could lead to sweeping changes. >> Read the Full Article
  • Lost in the Amazon

    Wading in muck up to the rims of his black rubber boots, Manoel dos Santos proudly showed off his tall palms of acai (pronounced ah-sie-ee), the deliciously bitter Amazonian berry that American health food stores tout as a miracle fruit. “Ten years ago, we didn’t even have enough acai for ourselves to eat,” dos Santos told the first tour group to ever visit his community. >> Read the Full Article
  • 'Nanominerals' influence Earth systems from ocean to atmosphere to biosphere

    The ubiquity of tiny particles of minerals--mineral nanoparticles--in oceans and rivers, atmosphere and soils, and in living cells are providing scientists with new ways of understanding Earth's workings. Our planet's physical, chemical, and biological processes are influenced or driven by the properties of these minerals. So states a team of researchers from seven universities in a paper published in this week's issue of the journal Science: "Nanominerals, Mineral Nanoparticles, and Earth Systems." >> Read the Full Article
  • Melting glaciers will shrink grain harvests in China and India.

    The world is now facing a climate-driven shrinkage of river-based irrigation water supplies. Mountain glaciers in the Himalayas and on the Tibet-Qinghai Plateau are melting and could soon deprive the major rivers of India and China of the ice melt needed to sustain them during the dry season. In the Ganges, the Yellow, and the Yangtze river basins, where irrigated agriculture depends heavily on rivers, this loss of dry-season flow will shrink harvests. >> Read the Full Article
