Climate change could end California farming: Chu: "Scientific" American

LOS ANGELES (Reuters) - Secretary of Energy Steven Chu warned climate change could wipe out California's farms by the end of the century by destroying snowpack that supplies vital water to the nation's top agriculture state, the Los Angeles Times reported on Wednesday.

In his first interview since taking office last month, the Nobel Prize-winning physicist said his home state would suffer some of the most devastating effects of global warming if the nation did not act to slow its advance.

"I don't think the American public has gripped in its gut what could happen," Chu told the newspaper. "We're looking at a scenario where there's no more agriculture in California.

"I don't actually see how they can keep their cities going," he added.
