Forests play important part in cooling down local climate
13 May 2017
Forests take up CO2 from the atmosphere. At the same time, forests promote the turbulent mixing of air near the surface and transpire large amounts of moisture to the atmosphere.
In addition to their role in the global carbon cycle and hence in global climate regulation, forests play a role in regulating climate locally by exerting important controls on the exchange of water and energy between the surface and the atmosphere.
Although such physical mechanisms have long been understood scientifically, an immature understanding remains as to their importance for the planet as a whole relative to other prominent ecosystems types - like grasslands or croplands.
