Scientists just found a strange and worrying crack in one of Greenland’s biggest glaciers https://www.washingtonpost.com/news/energy-environment/wp/2017/04/14/scientists-just-found-a-strange-and-worrying-crack-in-one-of-greenlands-biggest-glaciers

This crack was already known in December last year. I posted an image of it in Reply #438 on: December 01, 2016, 09:39:09 PM »

I remember that, and I believe Andreas Muenchow has also mentioned it, if memory serves me well.

'A sensor in 3,000-foot-deep waters had found that in the warm, salty Atlantic layer, temperatures were even warmer than just a year earlier, in 2015. Those waters are likely flowing toward Petermann glacier’s grounding line and helping to melt the shelf from below.'

Great views of the Petermann and Jakobshavn canyons in the video on this page too
The canyon feeding Petermann gives a direct connect to all of inland Greenland.  Huge, and its already melting into a groove...

According to Andreas Muenchow https://twitter.com/AndreasMuenchow/status/852491527796523008 and Stef Lhermitte https://twitter.com/StefLhermitte/status/852873863427969024 it seems like it's a new crack.
