Current predictions of rainfall change in the West have indicated that rainfall may decrease by as much as 40 cm in some areas. Imagine a savannah location that experiences 100 cm of average annual rainfall and an average annual temperature of 20°C. If rainfall decreased by 40 cm per year, what would you expect to occur? The area within the curve for savannah would shift further to the right. The region would still be classified as savannah. The region would be classified as a desert. The area within the curve for savannah would shift further up.
