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.

First it's "Oh no! We don't have enough water!" and then it's "Oh no! That's too much water!" It's impossible to please you lot! ;)

I think I've seen that movie.

Megaflood sounds super metal!

And even after that, California will still be in a drought.

But on the plus side, Florida will probably return to the ocean.

When I was 19, many years ago, I thought we could just tell the world leaders, and they would fix all this stuff. But they already knew.

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
OhIfIMust
Is this what they mean by "it never rains, but it pours?"
zerogenix
"when it rains, it pours"
3nd3rwiggin
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.
3nd3rwiggin
anti-caking... Ant-caking would be a tough sell.

We’ll, we do need the water…

"Good news and bad news! I figured out how to solve CA's drought!" And the bad news? "It's a massive flood."

Well, if it does happen, at least the state won't be on fire anymore.

Combined with the San Andreas sheering the rest off in the next big one.

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

"...which dumped nearly 10 feet (3,000 mm) of rain in parts of California over a period of 43 days." ... ... uh, sweet fuckin' Jesus.

Well, I live in Monterey, so I'd love to have an inland sea and coast. Be much cooler!

I can swim. Just not while holding all my stuff.

in sewer water filled with broken glass and floating debris.
FeloniousMonk13
it bothers me that 'flood' is pronounced differently from 'food'. this needs to be sorted out immediately.

Good
hisdudenesselduderino
Well... they could use the water atleast

well fuck. now the evangelicals will be saying "We told you so!" even though their Yahweh promised not to send a flood for his next tantrum.

When the land dries up it hardens and the water skates over the top. You need plants if you wan the water to stay. Or dams.
FartPoweredPogoStick
Your body also requires iron but I don't think getting it 100mph is necessarily a good thing either.
TheHappyCreator
I was going to say this. We should collect as much rain water as we could.
dal42
Wouldnt a mega flood, consist of saltwater. Thats not good for much
SecondSince
Not like that though...
sonicthemariomasterchief
I've been meaning to take up boating this clinches it. I'm buying a boat
popefool
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.
Etherealvalentine
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.
satsukeshi
That's not including the amount we ship to other countries. Also, over 200 different crops grow there, and it would likely decimate billions

Of bees if it occurred when hives are in the fields

What's with capitalizing all the I's in the title?

I think it’s just blurry so the space between the dot and the i gets blotted out.

Corrupt L.A. Mayor said Suck It Up, Just Water (I paraphrase). Voters turned on him big time. Changed politics into "house cleaning" phase.

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

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

That's why you read the source that was posted to get the numbers
Enginerrrrrrrrr
More a "once in 1000 year flood" goes to "once in 20 years". The article is written poorly in terms of scientific verbiage
BatsArentBugs
Well, it’s less than triple, so I’m ok with it.
TheUnstoppableWampas
That's why they posted the link to the paper, which said the megaflood chances were 1% to 0.5%.
comacomacomacomachameleon
at a 1% chance, that means it's about a coin flip of occurring in the next 75 years.
PaintedSlate
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.
TheUnstoppableWampas
That was the previous chance, assuming that their conclusion was correct it would now be 2%.
comacomacomacomachameleon
at 2%, it's 34 years.
Rogahar
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.
ZackWester
it could be 105% whit 100% been in the next 3 years still do nothing.

Don’t look up.

No they will do something, conveniently move away from california while buying property slightly inland for potential beachfront house

I sure hope they dont let people in there when there is a horrible flood

I’d love to have a few of these in California.

As someone who lives near Sacramento, which parts of California?

Live in Sac and just bought a home further up at 150 ft. I'll get a room ready for you.

San Francisco and the inland valley before the Sierra Nevadas. So, you're boned.
WoofBastard
San Francisco won't flood, it's on the bay at sea level. There'll be more water coming through the Carquinez Strait, that's all.
WoofBastard
If the level of the Bay rises it'll basically be the same as King Tide.

GemsAreOutrageousTrulyTrulyTrulyOutrageous
It's okay, we're fine in SacTown. We're at 50ft elevation! My hometown of Rio Linda (25ft) is fucked, tho!
MrStickyCheeks
Went to RLSH. I remember when Dry Creek flooded for a week.
GemsAreOutrageousTrulyTrulyTrulyOutrageous
Same. Wait, which time? I remember that farm just a few mins walk north from RLHS whose fields would flood into a big lake most winters.
MrStickyCheeks
Early 2000s.
sleix
Dude, we even get one good rainstorm and Rio Linda's the first spot to flood. That and the Consumnes and everybody's crying after that.
GemsAreOutrageousTrulyTrulyTrulyOutrageous
1997 was a fun storm year. Curved Bridge Road became an island.

Makes me wonder why nobody's ever built on stilts over in Rio Linda, do you guys even remember the last big levee break? :D
