Whilst we are all aware of the galciers retreating across the world I saw it first hand when I went up to Montenvers, the difference in the glacier from early mid 1990's to now was stark.
Now there are concerns about collapse in Planpincieux glacier on the Grandes Jorasses threatening Courmayeur.

Not good news, obviously, but what to do about trying to stop this - no easy answers.
