LOS BANOS, Calif. (AP) — Warning that weather-related disasters will only get worse, President Barack Obama said Friday the U.S. must rethink the way it uses water as he announced new federal aid to help drought-stricken California.

Obama drew a clear connection between California’s troubles and climate change as he toured part of a farm that will go unsown this year as the state faces its worst drought in more than 100 years. Even if the U.S. takes action now to curb pollution, the planet will keep getting warmer “for a long time to come” thanks to greenhouse gases that have already built up, Obama said.
