Copenhagen is adapting to a warmer world with rain tunnels and 'sponge parks'

Copenhagen, Denmark, is expected to receive 30% more rainfall by the end of the century. The city is responding with a massive long-term adaptation plan. Enghaveparken, pictured here, is part of that plan. The park was redesigned after a 2011 flood to be able to transform into a massive reservoir in the event of heavy rain.
