Glacier breaking captured in Greenland

Glacier breaking capture in Greenland Glacier breaking capture in Greenland.

A four-mile iceberg breaking away from a glacier in Greenland was captured by a team of scientists on June 22 2018.

The entire event captured on camera can help scientists examine how large icebergs may affect future sea levels. David Holland, a professor at NYU's Courant Institute of Mathematics and NYU Abu Dhabi, who led the research team, said: "Global sea-level rise is both undeniable and consequential. By capturing how it unfolds, we can see, first-hand, its breath-taking significance". The calving began at 11.30pm when the four-mile-long iceberg started splintering off the Helheim Glacier. It took just 30 minutes for the iceberg to completely separate and the researchers condensed the event into a minute-and-a-half long clip.

Denise Holland, the logistics coordinator for NYU's Environmental Fluid Dynamics Laboratory and NYU Abu Dhabi's Center for Global Sea Level Change, who filmed the calving event, adds: "Knowing how and in what ways icebergs calve is important for simulations because they ultimately determine global sea-level rise. The better we understand what's going on means we can create more accurate simulations to help predict and plan for climate change. The range of these different iceberg formation styles helps us build better computer models for stimulating and modeling iceberg calving."

Scientists are currently researching how the melting ice sheets could affect the world's sea levels as global temperatures continue to rise. A 2017 estimate suggested that a collapse of the entire the Western Antarctic Ice Sheet would result in a 10-foot-rise in sea level—enough to overwhelm coastal areas around the globe, including New York City.
