If you wear a white t-shirt in the sun it will keep you nice and cool compared to a black one, right?

If you take a nice white glacier and then sprinkle dark microscopic air pollution particles on it – the same principle applies. Except, instead of sweaty armpits, you get failed hydro projects, crop failures and depleted water supplies for communities downstream.

In December last year I clambered up the southern-most 6000m peak on the planet, returning with a rucksack full of snow.

The results would help show just how quickly we are not only killing ourselves with air pollution in Santiago, Chile – but the speed at which we are destroying our glaciers too.
