The southward expansion of the Sahara is more likely to be due to grazing practices of domesticated animals. In the northernplains, rainfall has not changed much, but temperatures are going up,increasing evaporation from the soil. I am also a scientist who builds and uses models to study potential impacts.

He proposed that each one be designated a commonwealth for the purpose of regulating its water usage, which would remain under federal control without regard to state lines. more.
