Migrating snowline plays outsized role in setting pace of Greenland ice melt

Patches of snow and bare ice near the edge of the snowline provide an illustration of the difference in reflectivity between the two surfaces. Credit Clément Miège PROVIDENCE, R.I. [Brown University] — In a finding that may help scientists better predict sea-level rise in a warming world, Brown University researchers have found an underappreciated factor…

Insta-melt in Greenland, according to DMI

People send me stuff. h/t to WUWT reader “Theyouk” Here we have a graphic from the Danish Meteorological Institute that shows Greenland has increased it’s surface melt dramatically in a very short time.

The temperature at the Greenland summit station on…

A Geological Perspective of the Greenland Ice Sheet

Guest Geological Perspective by David Middleton Before we get to my geological perspective of the Greenland Ice Sheet (GrIS), let’s first have a look at the NASA perspective: Greenland Ice Loss 2002-2016 The mass of the Greenland ice sheet has rapidly declined in the last several years due to surface melting and iceberg calving. Research…
