Goms Valley, Valais, Switzerland (romandie/ats, Fre) - To melt or not to melt, that is the big question, when it comes to glaciers. Students from Germany’s Johannes Gutenberg University in Mayence are working on the basis that with a little help from humans, glaciers can not melt, or at least the melt rate can slow down. To test their theory they have used steel pegs to hold down a 15 metre wide and 3 metre high protective device, like a tent, over part of the Rhone glacier, at 2,300 metres. The idea is to stop the cold winds that blow from the glacier down towards the Rhone Valley below.
