Something big has just happened in the Antarctic, and scientists are scrambling to figure out what this means for the Earth.
A major development is being reported in Antarctica, and scientists are very concerned about what it means for the future of our planet. A huge crack in the fourth largest ice shelf on the continent has increased by an astonishing 10 kilometers since early January, and now the rift is 175 kilometers long along the Larsen C ice shelf.
The crack could reach the ocean in only weeks, creating a huge iceberg twice the size of Luxembourg. It’s a big concern for scientists, showing that global warming is already resulting in unstable ice in the Antarctic, which will lead to rising sea levels across the globe.
Larsen C would be the third casualty of the ice shelf, with Larsen A breaking off in 1995 and Larsen B separating in 2002.
“Larsen B was a turning point in our understanding,” said Ala Khazendar, a geophysicist at NASA’s Jet Propulsion Laboratory in Pasadena, California, in a Scientific American report. “It was the biggest collapse of its kind up to that point, and it served to demonstrate how ice shelves regulate the movement of ice from the interior of the ice sheet to the ocean.”
