Two researchers from New York University, who happen to be the Canadian husband and wife team of David and Denise Holland, were camping off Greenland’s Helheim Glacier which they were studying and had a camera set up for the overnight watch when they captured something spectacular.
The time-lapse video shows ice, half a kilometer high, breaking off in large chunks. How large? According to reports it is estimated at half the size of Manhattan. The sound according to David and Denise was very loud and booming, like a billion ice cubes dropped into water at once, with that sort of crackling sound.

It is large scale crumbling of glaciers like seen in the video that have climate scientists concerned about rising water levels. Much like the afore mentioned ice cubes; when you add that much ice to a glass the water rises, the same goes for ice in the oceans. This video may be useful in making predictions of how global sea levels may react to some of the other glaciers that are at risk of dropping large amounts of ice into the oceans. This is one of the concerns about global climate change.
