The glacier that keeps collapsing

A glacier arch in Argentina has collapsed - but it's not due to climate change.

It's part of a cycle and means tourists can see the spectacle of huge chunks of ice falling off the glacier every few years.

The Perito Moreno glacier in Argentina's Patagonia region is one of very few globally that grows rather than shrinks but scientists say that overall the amount of glacial ice in the Patagonia region is decreasing.
