Mountain of evidence

Climate change has been blamed for a lot of things, sometimes not entirely based on the scientific evidence. But this is a first, at least to me:

From today's Guardian:

A vast chunk of Europe's most ill-famed mountain threatens to break loose and crash down in the next few days, a geologist monitoring the situation told the Guardian yesterday. Hans-Rudolf Keusen said 2 m[illion] cubic metres of the Eiger in the Bernese Alps, Switzerland - twice the volume of the Empire State Building - was rapidly working its way loose. He said the mountain appeared to have cracked open as an indirect result of global warming.

I'm not challenging the theory. It's just that the all-too-brief story offers no causal explanation, noting only that

It is natural for the Alps to erode. But evidence has grown in recent years that they are crumbling at a faster rate than normal. In 2004 three lumps of the Dolomites in northern Italy came loose.
