Largest Iceberg Calving Ever Filmed
Watching this video (below) will be the scariest 3:49 you will pass this year. It's a clip from James Balog's new documentary, "Chasing Ice," in which he shows in terrifying detail the unprecedented melting of the Arctic. This particular clip shows the largest iceberg calving ever filmed--the breakup of the lulissat glacier in Greenland, involving 7.4 cubic kilometers of ice. (For a look at Greenland and the Iulissat glacier in 2007, see Edward Readicker-Henderson's "The End of the World."
"Chasing Ice" is now playing nationwide. Go see it with a climate skeptic.
