Scientists have shown how a huge iceberg broke away from Greenland

Researchers also managed to capture on camera a video that shows the noticeable violence and speed of the ice breaking event that is now ongoing.

Thus far, according to the NYU scientists, the Thwaites Glacier-part of the West Antarctic Ice Sheet-has already drained a mass of water that's roughly the size of Florida.

June 22 at 11:30 local time was lifted chip of ice. - "Catching as it unfolds, we can see its value".

A team of scientists has captured on video a four-mile iceberg breaking away from a glacier in eastern Greenland, an event that points to one of the forces behind global sea-level rise. The video shows the HELHEIM glacier.

These fractures caused by sea level rising also indicate another strong repercussion for the upcoming years is that as these breaks continue to happen it will also be harder to control and predict how much and how often this will occur in the future.

"Global sea-level rise is both undeniable and consequential", said research team leader David Holland in a statement.

The video shows a tabular (wide and flat) iceberg separate, then travel down the fjord where it smashes into another iceberg. Meanwhile, smaller pinnacle icebergs, which are tall and thin, can be seen calving off and flipping over.

So far, the Thwaites Glacier has accounted for approximately 4% of global sea-level rise, an amount that has doubled since the mid-1990s.

Understanding how calving events take place is, the researchers say, important for developing simulations for sea-level rise brought about by climate change.

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). "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.
