Increased danger for mountaineers, as climate change melts the French Alps

Climate change is melting the French Alps, say mountaineers
Permafrost ‘cement’ is evaporating, making rocks unstable and prone to collapse with many trails now deemed too dangerous to use, Guardian,  Simon Birch, 24 Aug 18, For the tourists thronging the streets and pavement cafes of Chamonix, the neck-craning view of Mont Blanc, the highest mountain in the Alps, is as dazzling as ever.

But the mountaineers who climb among the snowy peaks know that it is far from business as usual – due to a warming climate, the familiar landscape is rapidly changing.

“Global climate change has serious and directly observable consequences in high mountains,” says Vincent Neirinck from Mountain Wilderness, a campaign group that works to preserve mountain environments around the world.

One of the consequences of climate change is the ongoing retreat of glaciers. “In the Alps, the glacier surfaces have shrunk by half between 1900 and 2012 with a strong acceleration of the melting processes since the 1980s,” says Jacques Mourey, a climber and scientist who is researching the impact of climate change on the mountains above Chamonix.

The most dramatic demonstration of glacial retreat is shown by the Mer de Glace, the biggest glacier in France and one of Chamonix’s biggest tourist hotspots which would now be unrecognisable to the Edwardian tourists who first flocked there.

“The Mer de Glace is now melting at the rate of around 40 metres a year and has lost 80m in depth over the last 20 years alone,” says glaciologist Luc Moreau.

A stark consequence of the melting Mer de Glace is that 100m of ladders have now been bolted onto the newly exposed vertical rock walls for mountaineers to climb down onto the glacier.

Another key impact of climate change in the mountains is that it is leading to an increase in the number of rockfalls; more than 550 occurred in the Mont Blanc massif alone between 2007 and 2015.
