1) San Diego is up to 23,0º hotter than in the nearby rural areas, Chicago is 21,0º hotter, Austin is up tp 15,0º hotter (all measured in Fahrenheit) 2) I found a study from The University of Copenhagen, that suggests that the urban area of Copehagen is about 5,0ºC hotter than nearby rural areas. I a adding pictures of a large park (former royal hunting grounds) just north of Copenhagen, and an image from the centre. And what strikes me is of course the amount of green in the park which obviously helps to keep the area cooler, compared to the completely paved area of Copenhagen, where heat is absorbed and emmited from. Both places are close to the sea, which helps cool the air down in both cases – and I should note, that it is very rare the temperature is above 25,0ºC, which is very comfortable. 3) I would suggest to try to reduce the paved area in the city, as well as creating more posibilities for shade with trees preferably. I have previously read that the materials/colours used on buildings facades and roofs also have a great impact on the surrounding climate, I think that would be worth looking at as well. And finally I would make sure that new buildings could be tested in a full city model, to see the full effects on the city. 4) I know there are policies on having more green in the city, which include green/moss roofs. Copenhagens building stock is fairly low, so changing the roofs would have a fairly big impact.
