As an illustration of my point .... indeed I'm sure crutal heatflow is an unknown in understanidng ice distribution, thickness and glacier speed. The point I was making is that the article (note the use of the word 'article', ie. not published paper) IMPLIES that there is some link to climate change observations. Just read the opening sentence : "Scientists have discovered what they think may be another reason why Greenland's ice is melting".

Since when can a mantle "hotspot" which will have been there for a timescale only measurable in geological terms sudenly be stated as the cause for a very recent change in icemass in Greenland ?
