Exceptional winter heat in the Andean mountains of South America has surged to 37C, prompting local scientists to warn the worst may be yet to come as human-caused climate disruption and El Niño cause havoc across the region.
The heatwave in the central Chilean Andes is melting the snow below 3,000 metres (9,840ft), which will have knock-on effects for people living in downstream valleys who depend on meltwater during the spring and summer.
