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 4 percent of global sea-level rise -an amount that has doubled since the mid-1990s.
"And here we can see his wonderful 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". The researchers saw, LiveScience reports, "puffs of ice" tossed into the air as a new iceberg began to break off from the glacier.
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.
News of rising sea levels and temperatures have become so common in headlines and reports, it is possible that the general public is becoming desensitised to it all. Hopefully, it will help researchers further understand the causes of sea-level rise around the world.
A 2017 estimate indicated that if the entire Western Antarctic Ice Sheet collapsed, sea levels would rise about three metres. It may also offer a chance to study iceberg calving.
The video shows a tabular (wide and flat) iceberg separate, then travel down the fjord where it smashes into another iceberg.
"Global sea-level rise is both undeniable and consequential", said David Holland, a mathematics professor at New York University. Meanwhile, smaller pinnacle icebergs, which are tall and thin, can be seen calving off and flipping over.
"The better we understand what's going on means we can create more accurate simulations to help predict and plan for climate change", Denise Holland, the logistics coordinator for NYU's Environmental Fluid Dynamics Laboratory who filmed the calving event, said in the statement.
