Thanks to the images of the European Space Agency's (ESA) Sentinel satellites, previous year two large cracks were detected in the glacier in 2019 and scientists have been closely monitoring the speed with which these cracks grow.
"This indicates that Pine Island ice shelf is weakening as a result of warm ocean water and this is important as the ice in the Amundsen Sea Embayment, where PIG is located, is the area where we scientists are most anxious about contributions to sea-level rise", Stef Lhermitte, a remote sensing scientist from the Delft University of Technology in the Netherlands, said to ABC.
"It is clear from these images (that the Pine Island Glacier) is responding to climate change dramatically", he added.
While the world is dealing with climate change issues Antarctica has recorded almost 64.9 degrees Fahrenheit, which is a new temperature record on the continent.More news: Trump says peace deal with Taliban ‘very close’
PIG, along with its neighbor Thwaites Glacier, connects the West Antarctic Ice Sheet with the ocean.
Thanks to the combination of both optical and radar images from the Copernicus Sentinel satellite missions, growing cracks were spotted in the Pine Island Glacier a year ago, and since then, scientists have been keeping a close eye on how quick the cracks were growing.
Previously the ice shelf calved once a decade.
Icebergs calving from glaciers is a natural process. Scientists worry that this persistent retreat could be a sign that a runaway melting cycle is in effect: As comparatively warm sea water laps at the newly exposed edges of an ice shelf, melting accelerates, the ice shelf stretches and thins, and further calving becomes ever more likely. These two glaciers have been losing ice over the last 25 years ...More news: Trump trolls Cuomo with 'Fredo' tweet ahead of White House meeting
"This indicates that Pine Island ice shelf is weakening as a result of warm ocean water and this is important as the ice in the Amundsen Sea Embayment, where PIG is located, is the area where we scientists are most anxious about contributions to sea-level rise", Dr Lhermitte said. "A shrinking outlet glacier is usually doing three things: thinning (mostly at the seaward edge), retreating, and accelerating".
According to NASA, the region around the two glaciers contains enough vulnerable ice to raise the ocean by 4 feet (1.2 meters).
"It's one of the fastest changing areas on the Antarctic ice sheet", said Ben Galton-Fenzi, a senior scientist with the Australian Antarctic Division. The largest of them was so big, it was even given a name: B-49. 11 Feb from pine island broke away a huge chunk of 350 square kilometers.More news: Barnes & Noble pulls alternative book covers following criticism
