Repeat Photography & Global Warming

Repeat photography is pretty straight-forward: multiple pictures taken from the same spot years apart.   The technique is useful to determine and document changes in climate and human impact on the environment.   Wired Magazine has a fascinating series of repeat photos taken by the US Geologic Survey that show restored archeological sites, rivers that have moved, and glaciers that have all but vanished.   

Global warming anyone?
