That Larsen C ice shelf is now said to be in its last days.... "The crack has spread 17 miles over the past six days."
And this even as it's late fall in Antarctica, approaching winter.
Here's the graphic from the UK-based Project Midas team:
This ice shelf is floating, so it won't directly affect sea level. But, as Climate Central writes,
Once it breaks off, scientists are concerned that the rest of ice shelf could collapse afterwards, a fate that befell Larsen A in 1995 and Larsen B in 2002. In Larsen B’s case, the ice shelf collapsed in the span of a month following an influx of mild air.
