• California air board plans new regulations

    The California Air Resources Board said on Friday it would step up the pace of new regulations to fight global warming in the most populous U.S. state. The air board also added measures that go beyond the requirements of California's 2006 landmark law to reduce carbon dioxide and other greenhouse gas emissions by 25 percent by 2020. >> Read the Full Article
  • APEC leaders agree climate change pact at summit

    Asia-Pacific leaders agreed on Saturday to adopt a "long-term aspirational goal" to reduce greenhouse gas emissions, Australian Prime Minister John Howard said. Howard said 21 Asia-Pacific leaders meeting in Sydney agreed on the need for all nations, developing and developed, to contribute according to their own capacities and circumstances to reducing greenhouse gases. >> Read the Full Article
  • Atlantic subtropical storm heads for N. Carolina

    Subtropical Storm Gabrielle churned steadily across the Atlantic toward North Carolina early on Saturday, prompting warnings of rain and strong winds and currents in coastal areas as early as Sunday morning. >> Read the Full Article
  • Shipping industry needs global emmisions regulation

    The world's shipping industry needs global regulations that are consistently enforced by the United Nations if it is to cut emissions, the chairman of the International Chamber of Shipping said on Friday. Public pressure is building for ship owners to curb air pollution and take part in markets in permits to emit sulfur and greenhouse gases. >> Read the Full Article
  • NOAA: Arctic Regional Sea Ice To Decline 40 Percent Before 2050

    WASHINGTON - A new study by NOAA scientists shows that areal sea-ice coverage of the Arctic Ocean will decline by more than 40 percent before the summer of 2050, compared to a 1979-1999 base period. These findings are based upon a study of national and international computer models that closely match the observed sea-ice extent over the 20-year baseline period of 1979-1999, and then project forward in time to determine any changes. >> Read the Full Article
  • NOAA Experts: La Nina Is Coming

    WASHINGTON - Scientists with NOAA’s Climate Prediction Center say that La Nina is on its way in today’s release of the monthly El Nino/Southern Oscillation Diagnostic Discussion. “While we can’t officially call it a La Nina yet, we expect that this pattern will continue to develop during the next three months, meeting the NOAA definition for a La Nina event later this year,” said Mike Halpert, acting deputy director of the Climate Prediction Center in Camp Springs, Md. >> Read the Full Article
  • Tipping Points In Earth System, Not Always Smooth

    University of East Anglia - The Intergovernmental Panel on Climate Change in its many excellent reports tends to portray climate change as a smooth transition. Although the projections are rarely straight lines the underlying system and its responses appear ‘linear’ in mathematical terms. There are, of course, exceptions to this, notable ones being the possible collapse of the Atlantic thermohaline circulation or irreversible melt of the Greenland ice sheet, which both get significant attention in the latest IPCC report. These represent large scale ‘non-linear’ components of the Earth system. >> Read the Full Article
  • APEC draft climate statement seen a compromise

    Asia-Pacific officials agreed on Friday to a draft climate statement which reaffirms a U.N. treaty on fighting global warming, while urging non-binding "aspirational targets" for greenhouse gas reductions, a delegate said. But the climate statement, which has emerged after tough negotiations following a split between developing and developed members of the Asia Pacific Economic Cooperation (APEC) forum, remains to be agreed to by the 21 Asia-Pacific leaders. >> Read the Full Article
  • New Research Identifies How One Storm Can Affect Another

    Weather forecasting and climate modelling for the notoriously unpredictable Sahel region of Africa could be made easier in the future, thanks to new research results coming from the African Monsoon Multidisciplinary Analysis study (AMMA). University of Leeds - A paper published in Geophysical Research Letters describes how the AMMA scientists gathered new atmospheric data by using satellite imagery to plot flight paths over areas where storms had produced very wet soils. Dropsondes (weather reconnaissance devices) were launched from a research aircraft above these wet areas to record data such as humidity, wind strength and temperature. The findings allowed the scientists to compare the atmospheric conditions above wet soils with those above adjacent dry soils. >> Read the Full Article
  • Scientists Make Dire Forecast for Alaska

    ANCHORAGE, Alaska (Sept. 7) - An analysis of 20 years' worth of real-life observations supports recent U.N. computer predictions that by 2050, summer sea ice off Alaska's north coast will probably shrink to nearly half the area it covered in the 1980s, federal scientists say. The summer sea ice off Alaska's north coast will likely shrink considerably by 2050, said James Overland of the National Oceanic and Atmospheric Administration. Here, a ship is seen 50 miles north of Point Barrow in 2002. Such a loss could have profound effects on mammals dependent on the sea ice, such as polar bears, now being considered for threatened species status because of changes in habitat due to global warming. >> Read the Full Article
