GEOGRAPHY IN THE NEWS:

U.S. trees are on the move. Between 1980 and 2015, several tree species associated with America's eastern woodlands -- including white oaks, hollies, and sugar maples -- have shifted their range, often westward (in the case of deciduous trees) or northward (in the case of coniferous trees).Scientists are still trying to figure out why, exactly, this has happened, but it seems to be linked to changes in physical geography, including historic rainfall patterns and temperatures. www.theatlantic.com/science/archive/2017/05/go-west-my-sap/526899/
