Study suggests trees are crucial to the future of our cities

“The shade of a single tree can provide welcome relief from the hot summer sun. But when that single tree is part of a small forest, it creates a profound cooling effect. According to a study published today in the Proceedings of the National Academy of Sciences, trees play a big role in keeping our towns and cities cool. 

“According to the study, the right amount of tree cover can lower summer daytime temperatures by as much as 10 degrees Fahrenheit. And the effect is quite noticeable from neighborhood to neighborhood, even down to the scale of a single city block. 

“The data show that forty percent canopy cover is the threshold required to trigger the large cooling effects that trees have to offer. The greatest amount of cooling happens once that threshold is crossed over the scale of a city block or larger.”
