MOST GLACIERS ARE RETREATING |
| Caption: |
Global warming is the primary cause for retreat of most of the world's glaciers, like Muir Glacier in Glacier Bay National Park, Alaska, shown here. Photograph (b) was taken from the same vantage on August 31, 2004. Between 1941 and 2004 this glacier retreated over 12 km (7 mi.) and thinned by more than 800 m (875 yd.). Vegetation in the foreground of (b) is now growing where there was only bare rock in 1941. (National Snow and Ice Data Center, [a] W. O. Field, [b] B. F. Molnia) |
