2. From The Article: " . . . All Indicators That Something Terrible Is Afoot In W. Greenland."

Did a huge melt water pulse issue from the Jacobshavn Glacier on January 16, 2016? Dr Jason Box appears to be concerned that it has. Image source: Dr. Jason Box.)

Perhaps more ominously, this widespread clearing of ice from these Arctic bays occurs in concert with what appears to be a large ice-calving event along the ocean-facing front of the Jacobshavn Glacier. In the above graphic by Dr. Jason Box (see more here), we see a large retreat of the glacier together with what looks like a major sediment outflow. Sediment hitting water in this way would be a sign that a very large volume of water had been expelled along the basal zones of the Jacobshavn. In addition, the ice itself appears to have been forcibly ejected. This apparent sediment flush, the concave bowing of sea ice away from Disko and Uummannaq and the inland recession of the calving face are all indicators that something terrible is afoot in Western Greenland.

A large flush of melt water coming from Greenland during Winter would, indeed, be that terrible thing. Something that now may become a more and more common feature of our age as Winter continues its ongoing retreat against a relentless assault by human greenhouse gas emissions.
