Ever seen a 5km wide glacier calving?

In the spring of 2005, acclaimed environmental photographer James Balog headed to the Arctic on an assignment for National Geographic to capture images to help tell the story of the Earth’s changing climate. 

Using modified solar powered time-lapse cameras mounted in precarious positions the film compresses years into seconds and captures ancient mountains of ice in motion as they disappear at a breathtaking rate.  It's an awesome piece of work we would highly recommend.  Trailer below highlights the largest calving event ever filmed- lasting for 75 minutes and the glacier retreated a 1.7km across a calving face nearly 5km wide. The height of the ice is about 900m, 90- 120 m above water and the rest below water.
