View Melting Glaciers in Google Earth
With concerns of global warming, one of the most dramatic signs often shown are photos of places like Glacier National Park where some glaciers have all but completely melted. One of the Google Earth Community members known as 'blt' has been posting some interesting information on the topic. He started with a post showing examples of retreating and advancing glaciers viewable in Google Earth. Then blt posted an image overlay showing a diagram from the Seattle Times showing the retreat of glaciers around Mt. Ranier 
. Next blt managed to get (or make) a Google Earth file showing data from the GLIMS (Global Land Ice Measurements from Space) database from the National Snow and Ice Data Center (NSIDC). This file shows the state of glaciers around the world and categorizes them whether they are advancing, retreating, stationary, etc. It may be surprising to some how many glaciers are actually still growing and advancing. Google Earth gives everyone an opportunity to do their own visual analysis of glaciers and compare it with other official data sources. Thanks blt!
