Read here. Reporter claims Greenland ice mass loss is over 300 gigatonnes per year, when it's actually been trending about 12 gigatonnes/year. Of course, if he was correct, there would have been a noticeable world sea level rise but that has not happened. And, the fact that Antarctic ice mass growth offsets Greenland's loss is conveniently glossed over.
The reporter is also confusing the actions of the outlet glaciers with the actual Greenland ice sheet. The outlet glaciers are very vulnerable to melting where they meet warmer waters that have arrived in area. The melting and 'calving' at glacier edge actually speeds up movement for the entire glacier. The warmer waters and outlet glaciers melting though, are not due to warmer air.
