• 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
  • Religious Leaders Unite In Prayer On Climate Change

    Religious leaders united in a silent "prayer for the planet" alongside a retreating Greenland glacier on Friday as part of a widening spiritual drive to combat climate change. "In our small world we all need to struggle together," said Sofie Petersen, the bishop of Greenland, of the meeting of Muslims, Jews, Buddhists and Christians aboard a cruise ship amid icebergs near Illulisat on the west coast. >> Read the Full Article
  • Bodies wash up in Nicaragua from deadly hurricane

    Bodies of Miskito Indians killed by Hurricane Felix floated in the Caribbean off Central America and washed up on beaches on Thursday as the death toll from the storm rose to over 60. Many of the dead were traveling by boat when they were hit by huge waves as Felix struck near the border between Honduras and Nicaragua on Tuesday as a giant Category 5 storm. >> Read the Full Article
  • APEC officials agree on global warming statement

    SYDNEY (AP): Pacific Rim nations on Friday reached agreement on a joint statement on global warming, overcoming bickering between rich and poor nations about whether to include targets on emissions, two Asian officials said. Experts from the 21-member Asia Pacific Economic Cooperation forum approved the wording of a final draft statement on climate change that would be handed to leaders at their summit starting Saturday, the officials said. >> Read the Full Article
  • Carving Out a New Idea of the Past

    There was bad news and good news aboard the U.S. Coast Guard icebreaking vessel Healy during a voyage to the Arctic Ocean. The bad news was a disturbing lack of sea ice, which, combined with strong winds, prevented the vessel from maintaining a steady position in the Arctic's Chukchi Sea. But the good news was that the ice-free seas gave the researchers a rare opportunity to make intricately detailed maps of the region's seafloor. >> Read the Full Article
  • NOAA study backs up predictions of sea ice loss

    Sea ice loss in regions of the Arctic is likely to exceed 40 percent by 2050 compared with the 1980s, according to an analysis of ice computer models by researchers at the National Oceanic and Atmospheric Administration. >> Read the Full Article
