Scientists in Chile have blamed climate change for the sudden disappearance of a lake in the south of the country.

Park rangers who patrolled the area in the Magallanes region in March reported that the two-hectare (five-acre) glacial lake was its normal size.

But two months later they found a huge dry crater and stranded chunks of ice that previously floated on the water.

Experts now say melting glaciers put pressure on an ice wall that acted as a dam, causing it to give way.
Water in the lake flowed out of the breach into a nearby fjord and then out to the sea, said Andres Rivera, a glaciologist with Chile’s Centre of Scientific Studies.
