The cities are displayed as dots of different colours and sizes. The colours represent the share of green and blue urban areas inside the Urban Morphological Zone of the city, the size of the dots reflects the population density within the core cities’ UMZ. The background map is the result of climatic modelling and represents the number of combined tropical nights (T>20°C) and hot days (T>35°C) for the period 2071 to 2100.
