Athens made extreme heat a governance priority in 2021, appointing Europe's first Chief Heat Officer. Its most visible public tool is Extrema, a smartphone app that turns satellite temperature data into a personal heat-risk score and routes residents to the nearest cooling park, shaded street or air-conditioned refuge. It is a small, practical answer for a city that keeps getting hotter.
