The right number of trees in a city will help to lower temperatures on hot summer days
Trees might be important for the future of our cities - climate change short science news

While one tree provides shadow and a little relief from high temperatures in the future, a new study suggests that to obtain a profound cooling effect would require small groups of trees, or even a small forest.

The right number of trees can lower the temperature in cities by as much as 10 degrees Fahrenheit (5 to 6 degrees Celsius).

Keeping temperatures more comfortable at hot summer days, which will occur more frequently due to global warming, can make a big difference for those working and living in the cities. Trees may thus appear to be very important for the future of our cities.
