Claim: low solar activity will melt Greenland’s ice faster

From the AGU: Sun’s activity controls Greenland temperatures WASHINGTON, D.C. – The sun’s activity could be affecting a key ocean circulation mechanism that plays an important role in regulating Greenland’s climate, according to a new study. The phenomenon could be partially responsible for cool temperatures the island experienced in the late 20th century and potentially…


Michael Mann and Stefan Rahmstorf claim the Gulf Stream is slowing due to Greenland ice melt, except reality says otherwise

UPDATED – see below From your “Day after Tomorrow” department (where a slowing Gulf Stream turned NYC into an icebox) comes this claim from the bowels of Mannian Science. Unfortunately, it looks to be of the caliber of Mann’s Hockey Schtick science. As WUWT reported on a peer reviewed paper last year, H. Thomas Rossby…

This is an example of a supraglacial lake and rivers on the surface of the Greenland Ice Sheet. The water flows down a hole (a moulin) in to the ice sheet in the center right.

Cornell University’s Greenland ice melt hype

From Cornell University and the Department of Inflated Headlines come this misleading claim that really should be anything new, and certainly not “groundbreaking” as they claim in this press released. After all, the tops of glaciers have been melting in the summer and making runoff meltwater which finds its way to the bottom of glaciers…


Will Greenland Begin Accumulating Ice in 2015 and Beyond?

Guest post by Jim Steele, director emeritus Sierra Nevada Field Campus, San Francisco State University. Based on NOAA’s 2014 Arctic Report Card, the past 2 decades of ice loss in Greenland has slowed dramatically in 2013-2014. In contrast to Velicogna’s (2014) previously published average mass loss of 280 +/-58 gigatons/year using GRACE satellite data, or…
