1st known 'river piracy' case causes river to dry in 4 days

Scientists have observed the first case of "river piracy", in which the flow of one river is suddenly diverted into another. The diversion of meltwater due to the retreat of a glacier made Canada's Slims river disappear in four days, scientists said. Researchers attributed the first-ever phenomenon to human-caused climate change, warning of more global river piracy events in future.
