There aren’t many places we can see the effects of climate change as dramatically as on the world’s glaciers. A few months ago, we asked our friends at the Extreme Ice Survey to send us a video to help 350 supporters visualize what glacial retreat really means. Using time-lapse and conventional photography and video, they put together this stunning clip of 350 days in the life of the retreating Mendenhall glacier near Juneau, Alaska.
