UCLA Expert: Daniel Swain: Assistant Researcher and Climate Specialist, Institute of the Environment and Sustainability

Synopsis: As California struggles with severe drought, global warming has doubled the likelihood that weather conditions will unleash a deluge as devastating as the Great Flood of 1862, shows a recent study by UCLA’s Daniel Swain. According to the new research, a disastrous “megaflood” could bring so much water to some areas of the state that it could completely drown entire stop signs on a neighborhood street.

UCLA News: It would probably be “bigger in almost every respect” than what scientists have come to call the “ARKStorm scenario” of 1862, Swain said. Such an event “would likely produce widespread, catastrophic flooding and subsequently lead to the displacement of millions of people, the long-term closure of critical transportation corridors and ultimately to nearly $1 trillion in overall economic losses.”
