The Pine Island Glacier in Antarctica is often referred to simply as “PIG,” according tomedia CNET. When it produces large icebergs, they are nicknamed “little pigs”. It sounds lovely, but when you look closely at the glacier, it’s worrying. The European Space Agency (ESA) Copernicus Sentinel 1 satellite recently traced a collapse on the Songdo glacier, stripping out an 115-square-mile (300-square-kilometer) iceberg, about the size of Orlando, Florida.
ESA released a video from 57 satellite images from February 2019 to February 2020. The video shows the rift in the glacier growing before the iceberg splits and breaks into smaller “pig” fragments.
NASA calls the Pine Island Glacier “one of the fastest retreating glaciers in Antarctica” and says the region is in a “sufficiently fragile area that will raise global sea levels by 1.2 meters (4 feet).”
Since the cracks were discovered by satellites last year, the ESA has anticipated the latest iceberg collapse. The largest fragment is now called “B-49”.
“The Copernicus Sentinel 1 all-weather satellite has built a window through which the public can watch similar events in remote areas around the world,” said Mark Drinkwater, senior scientist at ESA and an expert on the ice. Disturbingly, the daily stream of data reveals that the climate is redefining the face of Antarctica at an alarming pace. “
