Climate change is putting Californians at risk of a massive flood that would cost $1 trillion in damage, displace millions of residents and submerge parts of Los Angeles and Sacramento, according to a new study.

Researchers with University of California Los Angeles found that climate change is doubling the chances of biblical flooding to occur in The Golden State.

And with each degree the Earth is warming, the odds and size of the next megaflood ‘is bigger in almost every respect,’ Daniel Swain, a UCLA climate scientist and co-author of the study, said in a statement.
