I like the actual content of the Ski-ing but all this Global warming talk is doing nothing to ad to the programmes appeal.
As a matter of fact of course the glaciers are melting as they have been doing for Eons. In addition the melt will speed up naturly as the ice losses mass. Just watch your snowman melt.Slow at first and then rapid decay.
Of course the Earth may be getting warmer but I remember back in the Seventies that the scientists were forecasting a new Ice Age.
Naw stick to the ski-ing and let nature take it's course.
