It is well known that climate is changing. One of the most well-understood aspects of such change for scientists is urbanization. However, the public may not be as aware of all of the ways cities can affect weather and climate. Cities modify temperature through urban heat islands, alter the natural water (floods, rainfall) and carbon cycles, and increase air pollution. Join Trees Atlanta for this exciting talk, which will discuss the simple to complex ways cities affect our climate and how trees can mitigate some of these changes.
