We know trees can reduce the urban heat island effect. A Nature Conservancy project is combining data on current tree coverage, heat, health, income, energy sources and more to determine where planting new trees would most help the communities currently most affected by the problem. (Note: The article’s in the context of Google’s role in the data analysis & visualization.)

I looked at the data from my local area, and it not only prioritized the areas I know are lower-income with fewer trees, it prioritized where people actually live, too. There are some areas that have very low tree coverage but are also rated very low priority…because they’re mall parking lots, light industry, heavy industry, office parks, etc.
