Incredible video shows 4-mile iceberg breaking in Greenland

Scientists were able to capture the moment when a huge iceberg breaks away from glacier in East Greenland.

Sea levels are rising and one of the culprits is the loss of ice from glaciers and ice sheets, victims of a warming planet.

But there is much that scientists have yet to learn about how and why this large-scale breakage happens, which makes it hard to predict when glaciers will fall apart, and how much that glacier disintegration will affect sea levels over time, David Holland, leader of the research team and a professor at New York University's Courant Institute of Mathematics and NYU Abu Dhabi, told Live Science.

The event plays out over 30 minutes, though the video has been condensed to around 90 seconds and shows a front-on angle of the glacier's edge, followed by a perspective further down the fjord. "By capturing how it unfolds, we can see, first-hand, its breath-taking significance".

A chunk of ice that would stretch from lower Manhattan to Midtown, as seen above, broke off from a glacier in Greenland.

The research team at NYU is examining the forces behind sea-level rise under a grant from the National Science Foundation.

As reported by EurekAlert, the video, which shows sea level rising as the ice from the glacier enters the ocean, may be viewed here: "The better we understand what is happening, the more precisely we can predict and plan for climate change", explains an employee at NY University, Denise Holland. As it does so, thin and tall icebergs-also known as pinnacle bergs-calve off and flip over. The contribution of Antarctica to sea-level rise remains small: only 7.6 mm in the period from 1992 to 2017. This can give researchers a sense of how the overall global climate is changing.

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 research is centered on the Thwaites Glacier.
