Changing World In Pictures

Argentina's Upsala Glacier was once the biggest in South America, but it is now disappearing at a rate of 200 metres per year.

Over on the BBC News Website they have photographs taken then an now to show the over riding effects of global warming, I don't know how any one could look at these pictures and say there is no such thing.

Unless you drive a hummer, and sort term petrol consumption over long term oxygen consumption is your priority.
