With its formerly submerged buildings now visible and drying in the sun, the Greek village of Kallio's emergence is a sign of severe drought. The settlement was flooded in the 1970s during the creation of the artificial lake Mornos, Athens' main water supply reservoir. But with Greece seeing its mildest winter and hottest July on record in 2024, following years without rain or snow in the region, the lake has receded, some locals say, by 40 metres.
