News Report “NASA: Sudden Massive Melt in Greenland” – My Comments On This Media Hype | Climate Science: Roger Pielke Sr.
The news headline, in particular, is an example of media hype. There was no “massive melt“. The term “massive” implies that the melt involved large masses of the Greenland icecap. They could have written “Sudden Extensive, Short-Term Surface Melting On the Greenland Icecap“, but instead chose to overstate what is a short-term weather event. Melting of surface ice occurs in Greenland whenever there are relatively warm surface air temperatures, as shown in the plot from Summit Station at the top of this post, and sunny skies, as reported by Thomas Mote in Seth’s article. Almost anytime, sublimation (direct transfer from ice to water vapor) occurs.
