For my final post I wanted to look at something that we had previously looked at in lecture, urban heat islands. The temperature of cities is significantly higher then the temperature of surrounding areas during all times of the year. This has to do with the fact that a large part of the land in cities is covered by surfaces that retain heat. In order to reduce the urban heat island effect many cities have started placing roof gardens on many buildings. Also people can plant more in the city in order the help reduce these effects.
