Chilean lake turns to desert, sounding climate change alarm

Amid an historic 13-year drought, rainfall levels have slumped in Chile that hugs the continent's Pacific coast.

Higher air temperatures have meant snow in the Andes, once a key store of meltwater for spring and summer, is not compacting, melts faster, or turns straight to vapor.

The drought has hit mine output in the world's largest copper producer, stoked tensions over water use for lithium and farming, and led capital Santiago to make unprecedented plans for potential water rationing.
