17 January, 2005Polar News: Climate Model Portal, Gemini Images, Climate Change Research and More! ############################################ Accessible Climate Model Portal The Educational Global Climate Model <http://www.edgcm.org/> (EdGCM 2.3.4) provides a graphical interface to a 3D climate model developed at NASA's Goddard Institute for Space Studies (GISS). The software makes it possible for teachers and students to simulate past and future climate changes, and it links the climate model to both a database and scientific visualization utilities, making it simpler to create and organize data and images. EdGCM is free for Mac OS X and Windows. ############################################ Scientists Find Climate Change is Major Factor in Drought's Growing Reach "The percentage of Earth's land area stricken by serious drought more than doubled from the 1970s to the early 2000s, according to a new analysis by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. Widespread drying occurred over much of Europe and Asia, Canada, western and southern Africa, and eastern Australia. Rising global temperatures appear to be a major factor, says NCAR scientist Aiguo Dai." http://www.nsf.gov/od/lpa/newsroom/pr.cfm?ni=15300000000145 ############################################ A Stellar Debut for Gemini Observatory's Online Image Gallery http://www.nsf.gov/od/lpa/newsroom/pr.cfm?ni=15300000000143 ############################################ Research Team Discovers First Evidence of Microbes Living in a Rock Glacier "Scientists have discovered evidence of microbial activity in a rock glacier high above tree line in the Rocky Mountains, a barren environment previously thought to be devoid of life. Found in an intermittent stream draining from the glacier, the evidence includes traces of dissolved organic material and high levels of nitrates, said Mark Williams, a scientist at Colorado University (CU)-Boulder. The high nitrate levels are believed to be a result of microbes metabolizing nitrogen within the glacier, said CU-Boulder graduate student Meredith Knauf.
