Scientists are concerned because an ice shelf the size of New York City collapsed in East Antarctica, an area that had long been thought to be stable.
This satellite image provided by NASA, Aqua MODIS 12 on March 2022 shows the main piece of C-37 close to Bowman Island.
The ice shelf, about 460 square miles wide holding in the Conger and Glenzer glaciers from the warmer water, collapsed between March 14 and 16, said ice scientist Catherine Walker of the Woods Hole Oceanographic Institute. She said scientists have never seen this happen in this part of the continent, making it worrisome.
The issue isn’t the amount of ice lost in this collapse, Neff and Walker said. That is negligible. It's more about the where it happened. “East Antarctica is starting to change. There is mass loss starting to happen,” Fricker said. “We need to know how stable each one of the ice shelves are because once one disappears” it means glaciers melt into the warming water and “some of that water will come to San Diego and elsewhere.”
