That's the warning a University of Alberta geophysics researcher has for hydrocarbon and water drillers after discovering uncharted land forms beneath the surface of the province. Deep valleys, cut out by glaciers and then filled with loose aggregate rock, silt and sand, are hiding fresh water reservoirs and natural gas deposits. http://www.physorg.com/news174751818.html Space & Earth Wed, 14 Oct 2009 15:20:01 EST news174751818 Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council. Although degraded air quality is nearly always dominated by local emissions, the influence of non-domestic pollution sources may grow as emissions from developing countries increase and become relatively more important as a result of tightening environmental protection standards in industrialized countries. http://www.physorg.com/news173444507.html Space & Earth Tue, 29 Sep 2009 12:02:49 EST news173444507 (PhysOrg.com) -- Since May 2009, the tropical Pacific Ocean has switched from a cool pattern of ocean circulation known as La Niņa to her warmer sibling, El Niņo. This cyclical warming of the ocean waters in the central and eastern tropical Pacific generally occurs every three to seven years, and is linked with changes in the strength of the trade winds. El Niņo can affect weather worldwide, including the Atlantic hurricane season, Asian monsoon season and northern hemisphere winter storm season. But while scientists agree that El Niņo is back, there's less consensus about its future strength. http://www.physorg.com/news173426040.html Space & Earth Tue, 29 Sep 2009 06:54:34 EST news173426040 A new 2,000-year-long reconstruction of sea surface temperatures (SST) from the Indo-Pacific warm pool (IPWP) suggests that temperatures in the region may have been as warm during the Medieval Warm Period as they are today. http://www.physorg.com/news170598165.html Space & Earth Thu, 27 Aug 2009 13:23:44 EST news170598165 (PhysOrg.com) -- A new international research effort on the Greenland ice sheet with the University of Colorado at Boulder as the lead U.S. institution set a record for single-season deep ice-core drilling this summer, recovering more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future. http://www.physorg.com/news170516207.html Space & Earth Wed, 26 Aug 2009 15:10:01 EST news170516207 New research announced at the International Water in a Changing Climate Science Conference in Melbourne 24-28 August, implicates pollution from Asia, Europe and North America as a contributor to recent Australian rainfall changes. Australian scientists using a climate model that includes a treatment of tiny particles - or aerosols - report that the build up of these particles in the northern hemisphere affects their simulation of recent climate change in the southern hemisphere, including rainfall in Australia. http://www.physorg.com/news170499861.html Space & Earth Wed, 26 Aug 2009 10:20:01 EST news170499861 (AP) -- The global spread of swine flu will endanger more lives as it speeds up in coming months and governments must boost preparations for a swift response, the World Health Organization said Friday. http://www.physorg.com/news170053663.html Medicine & Health Fri, 21 Aug 2009 06:20:01 EST news170053663 Splat!
