A four miles wide iceberg was breaking away from Greenland's Helheim Glacier on June 22.

It cracked into pieces in a process called calving, an event that can be caused by warming oceans. 

The footage is sped up 1,600 percent.

Scientists worry that calving will happen on a disastrous scale in Antarctica, where the much larger Thwaites glacier, for instance, is believed to be a linchpin holding back the West Antarctic ice sheet.

New York University Oceanographer David Holland has been studying ocean and glacier interaction in Greenland for 12 years. 

The data from his current research feeds into an international collection of modeling groups who are trying to simulate sea level change. 

Time-lapse video shows a four-mile wide chunk of ice breaking away from the Helheim Glacier in Tasiilaq, Greenland, a rarely documented event called calving.
