Urban green spaces help to adapt to the changing climate. They reduce urban temperatures and therefore temper heatwave effects for people. Green spaces can also reduce flood risks. For more information, see the EEA report 'Urban adaptation in Europe: how cities and towns respond to climate change' This viewer shows the presence of green spaces in European cities in relation to vulnerable populations (i.e. areas with high proportions of the elderly or the unemployed) and social infrastructure (i.e. schools and hospitals).
