Watch a City-Sized Glacier Collapse
The makers of the movie Chasing Ice were able to capture on film the largest ice calving ever witnessed by humans (so far, but that might not last the way things are going with our planet's climate). It was the Jakobshavn Glacier (aka Ilulissat Glacier) in Western Greenland. The apocalyptic event lasted for more than an hour and when things stabilized, the glacier had retreated a full mile across a calving face three miles wide.
