Calving Event the Size of Manhattan

Again from the Guardian comes this piece, that features perhaps the most stunning, chilling, jaw-dropping piece of video I have seen this year - or for the past five years.

At about the 3 minute mark the researcher explains, in calm, measured tones, what you have just seen.  The understatement only highlights the enormity of what's happened, which is that a glacier the SIZE OF MANHATTAN ISLAND (7.4 cubic km) has calved off the Ilulissat glacier in Greenland.

It almost looks like CGI, it's that outside of one's normal frame of reference.  It's also part of the overall (and accelerating) melting of Greenland's ice that is contributing about 20% to the world's sea level rise.
