LOS ANGELES — The storms that have been battering California offer a glimpse of the catastrophic floods that scientists warn will come in the future and that the state is unprepared to endure.
Giant floods like those that inundated the Central Valley in 1861 and 1862 are part of California’s natural cycle, but the latest science shows that the coming megafloods, intensified by climate change, will be much bigger and more destructive than anything the state or the country has ever seen.
A new state flood protection plan for the Central Valley presents a stark picture of the dangers. It says catastrophic flooding would threaten millions of Californians, putting many areas underwater and causing death and destruction on an unprecedented scale. The damage could total as much as $1 trillion.
