Sea Level Rise Can't Be Stopped
riverat1 writes "Sea level rise won't stop for several hundred years even if we reverse global warming, according to a study published in the journal Nature Climate Change. As warmer water is mixed down into the oceans, it causes thermal expansion of the water. Under the best emissions scenario, the expected rise is 14.2 cm by 2100; under the worst, 32.2 cm from thermal expansion alone. Any water pumped from aquifers or glacial/ice sheet melt is added to that."
Serves you right. You let all those New Yorkers in and bad things happen....
Faster! Faster! Faster would be better!
It will be ok in North Carolina since their legislature said you can only use linear extrapolations of sea level rise to plan building in coastal areas. Guess they didn't get beyond simple algebra in school (no quadratic equations etc).
Should have known better than to try to save that ungrateful environment. I'm buying an SUV.
Suck my balls, you lying hippies!
What political party do you join when you don't like Bible-thumpers *or* hippies?
Any water pumped from aquifers or glacial/ice sheet melt is added to that.
How big is the effect of thermal expansion in comparison to melting of ice? How much would be the additional rise in the worst case scenario?
Screw Jesus. I want Noah. Praise be Noah!
Yes, this: http://geology.com/sea-level-rise/
But that map makes even a 60m rise seem not bad at all.
This may be a stupid question, but isn't there a way to collect massive amounts of CO2 from the atmosphere, compress the carbon into some sort of solid composite, and store it somewhere where it's land-locked (similar to how trees store carbon in wood)?
I know, I never liked Florida either.
Well, for one, in the US alone, more than half the population lives in a coastal area.
Even if just 10 percent are directly affected, that's still a large number of people.
In the US, can you imagine all the lawsuits and politics about how to move people, does the government have the right to do it, does the government have the obligation to do it, and who is going to pay for it?
For countries like Indonesia that are mostly islands, or in countries or areas that are largely below sea level, this could result in a major loss of housing and usable land.
Anything that changes ocean patterns could affect shipping and fishing, both of which would be major blows to the global and regional economies. If we lose major fish populations, that will increase food prices, and if shipping becomes riskier, that will affect the price of virtually everything.
It's a lot more than avoiding getting wet.
32cm is like, over 12 inches. That's gonna be noticeable.

It's a poorly understood fact that any unwanted facts can simply go "poof" if you scream LIBURAL LIBURAL LIBURAL over and over.
Because, of course, the laws of nature obey your political ideology.
Here's news, moron, the Universe doesn't give a fuck about Liberal vs. Conservative, Socialist vs. Capitalist. It does not fucking care. If pumping millions of years of sequestered CO2 into the atmosphere in the space of two centuries is going to cause serious climactic changes, it is absolutely fucking irrelevant who you fucking vote for, or whether you masturbate to Vladimir Lenin or Ayn Rand.
Fucking hell, you ideological fanatics are a tiresome, mentally handicapped lot. Don't like evolution because you think it falsifies your religion. Don't like acid rain or climate change because it means there are consequences to wide-scale and uncontrolled industrial activity. Don't like regulations because it kills your particular get-rich-quick-while-fucking-the-economy scheme.
Is there any part of you at all that isn't a selfish, greedy piece of stupidity? Is there any part of you that gives the least little fuck for anyone other than yourself? Or are you really the vile repugnant sociopathic troll you appear?

Now that there is nothing we can do about it, the shills can stop pretending it isnâ(TM)t happening.
Already, Exxon has stated the obvious - burning fossil fuels is warming the planet by increasing the co2 level; however had to mute it with a statement that we can handle the change.
I suppose a whiff of honesty is better than before.
Time to unload all that beachfront property. 32cm is like, over 12 inches. That's gonna be noticeable.
A-ha! I own the property just behind yours! I'm that much closer to having beachfront property!

No, this paper is a theory. Observation of sea level rise is evidence.
What if Jesus sent you scientists warning you what you were doing was bad?

That global warming is out there. It can't be bargained with. It can't be reasoned with. It doesn't feel pity, or remorse, or fear. And it absolutely will not stop, ever, until your tootsies are completely soaked.
Something tells me that 32.2cm won't affect all of Florida.
It's call tidal surge. And increased atmospheric energy leading to more frequent and more powerful hurricanes.
Florida's not going to be a very hospitable place to live or grow crops if large parts of it are under saltwater frequently.
Anyhow, screw future generations, I've got mine. They can just adapt to the new normal, they'll never miss what they never had in the first place.
the preceding comment is my own and in no way reflects the opinion of the Joint Chiefs of Staff
Maybe I am being overly optimistic, but 14.2cm in 80 years doesn't exactly seem so bad (or even 32.2cm for that matter). Surely cities that are going to be effected will have ample time to relocate those in "danger".
Too right. Let's move them into the last Indian reservations.
Exactly where would you propose we move tens of millions of people? Not only Florida and low areas of the Eastern Seaboard, but gulf coast and low lands of Texas, right up to Houston are at risk.

The Netherlands seem to be doing just fine below sea level. It might cause some economic harm, but it's not going to be a tragedy. Also, most low-lying islands are coral islands that follow sea level.
Tides in South Carolina routinely affect land 100 MILES inland. Just because 'you' are high and dry doesn't mean it's not a pressing national issue.

Nope, it is densest at 4C. I know this from spending my summers swimming in 4C water. The thermoclines set up, you get a bottom of near-freezing water, and the visibility is spectacular.

I never get this kind of map. If you take their logic, Netherlands should already be flooded. As far as I can see from my window, it isn't.
Higher sealevel just means building some infrastructure against flooding.
You need a decent government for that. In the U.S., we knew for decades that much of New Orleans was going to be underwater if a decent hurricane hit it (I first learned about it in college in 1992). Nothing of substance was done.
Here's a quick inventory of problems to cope with.
Florida has a maximum land height of 42 feet. A three foot rise in see level, plus shore erosion due to larger and more frequent storms could reduce Florida to a stub of the current state with central islands where the everglades are now.
Expanded erosion of barrier island and sand dunes along the gulf and eastern seaboard will eliminate thousands of square miles of existing shoreline, destroying some of the most valuable property in the country.
Much of the Mississippi delta and most of Louisiana will simply go away (a great deal of which is already below sea level due to subsidence from poor river engineering by the Army Corp of Engineers.)
The West Coast won't pass unscathed, because towns along the bays in both southern and northern California, will suffer significant land loss.
The simple fact is that the big cities of the world are virtually all coastal cities and as such will be seriously impacted. The amount of land shared be people and critters will shrink a couple percent (large coastal plains will be inundated... kiss Bangladesh and a number of small islands in the South Pacific goodbye.)
You bet we can engineer around it. Move cities slowly back. Build higher dikes and levees. Abandon places that are hopeless. Its just one more cost, and significant cost to consider as we continue to spew greenhouse gas into the air.
Water has no thermal expansion? Really? Basic physics huh?

And water is actually slightly compressible:

Do you have a clue how expensive the water management system in the Netherlands has been? Do you realize that the Netherlands is tiny compared with the areas under threat from sea level rise in the US alone? Hell, it's tiny even compared with Florida. Do you realize that duplicating the Dutch diking system for American coastal areas would likely bankrupt the country? Not to mention how future sea level rise will make it even more difficult for even the Netherlands to maintain the integrity of their diking system.
