Ice no more? Experts warn European glaciers could melt by 2100

It's not too late to save the ice on the Alps, but action has to be taken now. That's the warning from Swiss scientists who say that at the current rate, there could be no glaciers left at all on the Alps just 81 years from now. That would mean 40 million Olympic-sized swimming pools of ice would have disappeared, with devastating consequences for the environment and the economy. We spoke to climate scientist Harry Zekollari from the Swiss Federal Institute of Technology in Zurich.
