Extra Bits: More on the Wilkins Ice Shelf Breaking Up

At the beginning of April, the ice bridge holding Antarctica’s Wilkins Ice Shelf in place shattered. Today, the AP reports that since Friday, 270 square miles of ice have dropped off from the Wilkins Ice Shelf into the sea.

As noted here on April 6, the news about the shattered ice bridge came while we were learning more about the rate at which the Arctic sea ice is melting. What struck me most when I found this report this evening is the amount of ice that was lost since Friday, over the course of only five days. While we were busy with other things, these huge chunks of ice were falling into the sea, seen by humans only in satellite images.
