'Invisible Flying Rivers': How Trees Help Manage Stormwater: It’s a pretty abstract concept, but Antonio Nobre, one of Brazil’s leading climate scientists, described the impact of e blog post

It’s a pretty abstract concept, but Antonio Nobre, one of Brazil’s leading climate scientists, described the impact of evapotranspiration in a very cool way while talking to NPR’s Lourdes Garcia-Navarro in early November:
