Snowpack a Predictor of Lightning Ignitions and Flammability
Did you know that snow could be a predictor of forest fires? Scientists from the University of Washington and USGS found that a projected decrease in spring snowpack is correlated with an increase in number and size of fires that are started by lightning. Less snow also increases the severity of the burn. Depending on conditions, lightning strikes can cause fires that burn large areas. Many climate change scenarios predict decreases in the snowpack in areas like Yosemite, where this study was conducted, making conditions more suited for fires started by lightning. In a new report published in the International Journal of Wildland Fire, these scientists project nearly 20 percent more lightning ignitions and more than 20 percent more area burned at high severity annually by mid-century.

Red Alert! Valuable Mineral found in Alaska
The chemical that produces red color in television monitors and LED used for energy-efficient light bulbs has been discovered in the Taylor Mountains quadrangle of Alaska. Europium has been found by USGS scientists in dark, pellet-like grains of the mineral monazite along with other metals of commercial interest such as gold, collected from Taylor Mountain area streams. Currently, the U.S. europium supply is scarce and limited to ore found in California and imported from China. A report of the findings is available in the December 2009 edition of Explore, the Association of Applied Geochemists newsletter. For
