A new study by Science Advances shows climate change has already doubled the chances of a disastrous flood happening in California in the next four decades. And experts say it would be unlike anything anyone alive today has ever experienced.

Daniel Swain, a climate scientist with UCLA and a researcher involved in the study, describes a megaflood as, "a very severe flood event across a broad region that has the potential to bring catastrophic impacts to society in the areas affected." He said a megaflood is similar to the 1,000-year flash flood events seen this summer in the St. Louis area and Kentucky, but across a much wider area, such as the entire state of California.

These massive floods, which experts say would turn California's lowlands into a "vast inland sea," might have previously happened once in a lifetime in the state. But experts say climate change is increasing the likelihood of these catastrophic disasters, causing them to occur more like every 25 to 50 years.

Monterey Peninsula had a good flood in the late 1990's. South, North, and East highways were all flooded and the peninsula became an island

Morton Salt. Added ant-caking agents to the salt so it would not clump up even in high humidity. So, when it rains, it (the salt) pours.

The map is interesting. Remember, long ago the San Joaquin valley was a large inland sea - and it's been sinking for decades.

Problem is the area most affected would be the Central Valley. So that's 25% of US food production wiped out along with the CA aquaduct.

I would love for the aqueduct to disappear. No one should be shipping water to a desert. It's causing the rest of the state to become one.

That's not including the amount we ship to other countries. Also, over 200 different crops grow there, and it would likely decimate billions

I hate when they use the term "double the chances" with no numbers. is that from 25% to 50%, or 1% to 2%?

From 'once in a lifetime' floods to 'within 25~50 years'. so 1% to 2% is probably accurate

That's why they posted the link to the paper, which said the megaflood chances were 1% to 0.5%.

4 years ago | Likes 157 Dislikes 1

at a 1% chance, that means it's about a coin flip of occurring in the next 75 years.

4 years ago | Likes 58 Dislikes 0

Yeah, 53% at 1%/yr, 78% at 2%, 31% at .5%. But binomial-wise, it's the risk of multiple such floods happening that increases the most.

4 years ago | Likes 1 Dislikes 0

That was the previous chance, assuming that their conclusion was correct it would now be 2%.

4 years ago | Likes 27 Dislikes 0

at 2%, it's 34 years.

4 years ago | Likes 7 Dislikes 0

It could be 98% likely and the people with the power to change things would still do nothing and hope for the 2% chance of nothing.
