Arctic Permafrost Melt Releasing Carbon Dioxide At Unprecedented Rate
2013-02-12 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate. This release is being caused by melting of the Arctic permafrost, which has kept ancient carbon locked away for millennia; only to be exposed as more warmth and sunlight erodes the long-frozen soils, causing collapse and release of carbon. George Kling, an ecologist and aquatic biogeochemist at the University of Michigan,...

Melt Flow Testers perform measurements to ISO 1133-2.
2013-01-22 14:30:50| Industrial Newsroom - All News for Today
Complying with ISO 1133-2 requirements for materials sensitive to time-temperature history and/or moisture, CEAST MF20/MF30 are modular, single-weight measurement systems that conform to tolerances with regard to temperature accuracy and stability, specimen quantity, and pretreatment. Features include 8-test mass weight magazine and weight lifter (optional for MF20), Manual Mass Selector, and Hi-Res load cell (MF30 only). Encoder permits controlled extrusion of melt to defined height. This story is related to the following:Flow Rate Testers |

Melissa Block speaks with Dr. Karl Braganza, manager of climate monitoring at the Bureau of Meteorology's National Climate Centre in Australia, about why this is happening, and how Australians are coping. MELISSA BLOCK, HOST: All over Australia - Alice Springs, Adelaide, Sydney, Wagga Wagga - it's been an extremely hot summer and it's expected to get hotter. The continent is experiencing a record-breaking heat wave. Roads have melted...
Andean glacier melt threatens floods, then drought
2013-01-03 14:09:00| Climate Ark Climate Change & Global Warming Newsfeed
AlertNet: As glaciers melt in the Andes, western areas of South America can expect a period of repeated, extreme flooding that will later give way to drought conditions, creating new challenges for millions of people, researchers warn. Tropical Andean glaciers and high-altitude ecosystems are vital to the economies of Peru, Ecuador, Colombia and Bolivia. The 8 million inhabitants of Peru's capital Lima depend on them for drinking water. The Bolivian capital, La Paz, takes 30 to 40 percent of its drinking...
