Enormous 4 mile long iceberg filmed breaking from Greenland glacier

Scientists have closely followed the frozen river as a key indicator of global warming and sea level rise.

A new alarming threat rises and adds up to the ongoing concerns regarding the sea level continuous increase, as a 4.5-mile section fracture on Greenland's Helheim Glacier has been spotted 30 minutes after the end of the month of June.

The research team is now studying the forces behind sea-level rise-a development that has concerned scientists in recent decades because it points to the possibility of global disruptions due to climate change-under a grant from the National Science Foundation.

It's hard to get a sense of scale from the video, but the researchers pointed out in a statement that this iceberg would cover most of Lower and Midtown Manhattan.

"Global sea-level rise is both undeniable and consequential", observes David Holland, a professor at NYU's Courant Institute of Mathematics and NYU Abu Dhabi, who led the research team.

The 90-second video has captured the attention and concerns of several experts on the climate change matter, especially because the Helheim glacier dips into the ocean on eastern Greenland and it lost a very large chunk of ice that will be responsible for some eventual changes on sea level rise. The researchers saw, LiveScience reports, "puffs of ice" tossed into the air as a new iceberg began to break off from the glacier. But while there are abundant satellite observations of Antarctica's ice sheets, it's extremely challenging to gather data from the surface of the remote continent, Holland said. It contains enough water to cause a rise in sea level by 20 feet. It may also offer a chance to study iceberg calving. New video could help make more accurate predictions about calving events. The camera angle then shifts to show movement further down the fjord, where one tabular iceberg crashes into a second, causing the first to split into two and flip over. Meanwhile, smaller pinnacle icebergs, which are tall and thin, can be seen calving off and flipping over.

"The range of these different iceberg formation styles helps us build better computer models for simulating and modeling iceberg calving", said Holland.
