The disappearing Pedersen Glacier in Alaska

The image here shows two photos of the Pedersen Glacier in Alaska. The black and white image is from 1917, and the open green field is from 2005. I found those photos in this YouTube video after viewing a short video about how warm it is in the Arctic Circle this year, where glaciers are melting during the winter instead of forming new ice.

For more information, the USGS has this page which shows many more examples of disappearing glaciers in Alaska.
