After a 2005 trip to the Arctic for a National Geographic assignment that opened his eyes to the effects of climate change, photographer and filmmaker James Balog embarked on a mission to some of the most remote parts of the Earth to document evidence of our planet’s warming. The result is Changing Ice, a full-length documentary following Balog’s at-times-harrowing journey.
In one of the most dramatic segments, above, 7.4 cubic kilometers of ice break from the Ilulissat glacier in Greenland and fall into the sea. The Guardian reports that it is the largest ice “calving” ever caught on film. A witness on Balog’s research team described the event as “Manhattan breaking apart in front of your eyes.”
