[font size=3]Did a January Hurricane Just Set off a Massive Greenland Melt Event in Winter?[/font]
This freakish Winter theres something odd and ominous afoot.
Weve seen unprecedented above-freezing temperatures at the North Pole coincident with record low daily sea ice extents. Weve seen global temperatures hitting new, very extreme record highs. Weve seen climate change related storms raging across the globe flooding both the UK and the Central US, firing off record hurricanes during January in both the Pacific and the Atlantic even as other regions swelter under record heat and drought.
Now, it appears that Greenland is also experiencing an unprecedented melt during wintertime.

(59,583 posts)2. From The Article: " . . . All Indicators That Something Terrible Is Afoot In W. Greenland."
?w=900&h=750
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.
