B is dramatic evidence of global warming . Since the late 19th century, mean surface temperatures have increased significantly B temperatures in Albany, New York have warmed by more than 1 F B and the 1990's were the warmest decade on record.

Evaporation will increase as the climate warms, which will increase average global rainfall.
