Enormous 4 mile long iceberg filmed breaking from Greenland glacier

Researchers from NYU Abu Dhabi have caught an iceberg calving from a glacier in eastern Greenland on camera.

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.

Earth's biggest glaciers are in frozen Antarctica, and their breakup would be catastrophic for sea level rise; the loss of the West Antarctic Ice Sheet would release enough water to raise global sea levels by almost 10 feet (3 meters). That means it would stretch from lower Manhattan to Midtown in New York City, as you can see below.

Researchers from NYUAD, who are in Greenland to research the effects of climate change, captured footage of a large block of ice breaking off from the Thwaites Glacier and the effects of the movement on the sea level and surrounding ice (above).

The stakes go beyond the economy. "But we should not understate the view that some sectors could get something out of a U.S. The Trump administration engaged in a similar tit for tat last month with the European Union, Mexico and Canada.

Calving is when an iceberg breaks off from a glacier. So far, the Thwaites Glacier, a part of the Western Antarctic Ice Sheet that has already drained a mass of water that is roughly the size of Great Britain or the state of Florida, has accounted for approximately four percent of global sea-level rise.

In April this year, New York University received a $2.1 million, five-year grant from the National Science Foundation to better understand Antarctic glaciers and the forces behind sea-level rise. "And here we can see his unbelievable significance", notes the study's lead author David Holland, Professor, Institute of mathematics NY. "By capturing how it unfolds, we can see, first-hand, its breath-taking significance". Apart from the large chunk thin and tall icebergs known as pinnacle bergs also drift out to sea.

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

The team say they are continuing to study the causes of rising sea levels in an effort to help predict and plan for climate change.
