Sicilian lemon producer Rosario Cognata is furious: his fruits are burning and rotting due to droughts, while only a few kilometres from his field lies a dam of rainwater that is frequently discharged into the sea instead of being made available to help his crops. This dam, called 'Trinita', was built in 1959 and still has no certification to guarantee that it is in good working order. While Sicilians have always known drought, global warming is accentuating its frequency and intensity.
