Yet another troubling sign of climate change in the poles.
, scientists have discovered that a massive ice shelf around the size of New York City has collapsed.first spotted evidence that the Conger ice shelf had crumbled into the sea on March 17, although they speculate the event happened between March 14 and 16. At 460 square miles wide, the mass of ice is crucial for protecting the Conger and Glenzer glaciers from warmer ocean waters.
“It’s not a very large shelf,” Scambos told CNN. “But every time we’ve seen a shelf that is braced against an offshore island or even the coast of a bay, the glaciers behind it sense that there’s a back pressure, that there’s a force that’s resisting outward flow. In other words, they thin rapidly and they flow faster when the shelf is removed.”The location of collapse on the eastern part of the continent is also a huge wake-up call for scientists.
