Global sea level could rise 15 meters by 2300, study says

Global average sea-level could rise by nearly 8 feet (2.5 meters) by 2100 and 50 feet (15 meters) by 2300 if greenhouse gas emissions remain high and humanity proves unlucky, according to a review of sea-level change and projections by Rutgers and other scientists.

Since the start of the century, global average sea-level has risen by about 0.2 feet (0.06 m). Under moderate emissions, central estimates of global average sea-level from different analyses range from 1.4 to 2.8 more feet (0.43 - 0.85 m) by 2100, 2.8 to 5.4 more feet (0.85 - 1.65 m) by 2150 and 6 to 14 feet (1.8 - 4.3 m) by 2300, according to the study, published in Annual Review of Environment and Resources.

And with 11 percent of the world's 7.6 billion people living in areas less than 33 (10 m) above sea level, rising seas pose a major risk to coastal populations, economies, infrastructure and ecosystems around the world, the study says.

Sea-level rise varies over location and time, and scientists have developed a range of methods to reconstruct past changes and project future ones. But despite the differing approaches, a clear story is emerging regarding the coming decades: From 2000 to 2050, global average sea-level will most likely rise about 6 to 10 inches, but is extremely unlikely to rise by more than 18 inches. Beyond 2050, projections are more sensitive to changes in and to the approaches for projecting sea-level change.

"There's much that's known about past and future sea-level change, and much that is uncertain. But uncertainty isn't a reason to ignore the challenge," said study co-author Robert E. Kopp, a professor in the Department of Earth and Planetary Sciences at Rutgers University-New Brunswick and director of Rutgers' Institute of Earth, Ocean, and Atmospheric Sciences. "Carefully characterizing what's known and what's uncertain is crucial to managing the risks poses to coasts around the world."

Scientists used case studies from Atlantic City, New Jersey, and from Singapore to discuss how current methods for reconstructing past can constrain future global and local projections. They also discussed approaches for using scientific sea-level projections and how accurate projections can lead to new sea-level research questions.

A large portion of sea-level rise in the 20th century, including most of the global rise since 1975, is tied to human-caused global warming, the study says.

A mere 15 meter rise presumes the East Antarctic ice sheet will be mostly stable for next 282 years, and that seems very unlikely at the moment. Vast wealth created by oil creates equally vast political corruption and propaganda that will cause us to burn oil for much longer than makes sense. Even now, the oil companies take money from the U.S. government in the form of tax breaks and subsides to subsidize Republican corruption in a vicious cycle. The good news is we probably won't exceed an 80 meter rise by 2300-2500 and it may be easier to effect political change in the U.S. since the red states of Florida and Louisiana will be gone.

I wouldn't worry too much about a sea level rise of ~80 meters, it is the potential for ecological collapse with no ice left to buffer climate change that you might want to lose sleep over. Have a nice day.

Being that rock is a (practicably) incompressible substance, and that squooshing (a technical term) plastic rock off to the sides so that the sea-floor can sink, is measured in tens of thousands of years, I doubt if the time-scales involved would bring the matter to the record of human cataclysmic events.

It's kind of irrelevant to us since the 1 metre rise and 4-7 temp increase by 2100 will wipe us out. But for what it's worth, we have no way to quantify the impact of the methane bomb so I wouldn't be surprised if sea level rises were far greater.

"THE OCEAN FLOOR IS SINKING UNDER THE WATER WEIGHT FROM MELTING GLACIERS, AND IT'S AS BAD AS IT SOUNDS
"So much extra water is being added to the world's oceans from melting glaciers that the ocean floor is sinking underneath the increasing weight. This ocean floor deformation also means we have miscalculated just how much ocean levels are rising, and the problem could be far worse than previously believed.

"Over the past 20 years, ocean basins have sunk an average of 0.004 inches per year. This means that the ocean is 0.08 inches deeper than it was two decades ago. While this small fragment of an inch may not seem much, oceans cover 70 percent of our planet, making the problem bigger than it seems at first glance."

-Or maybe you're just lazy.
TheGhostofOtto1923

Theres even a term for it

"as the ocean bottom subsides elastically, the actual increasing volume of the ocean – called barystatic sea level rise – is masked from measurements based on satellite observations.

"That's because satellite readings only tell us one side of the story: geocentric sea level rise, as seen from the surface side.

"[B]ecause satellite altimetry observes sea level in a geocentric reference frame, global mean sea-level estimates derived from altimetry will not observe the increase in ocean volume due to ocean-bottom subsidence, and hence, they may underestimate [global mean sea-level] rise," the researchers explain in a new paper."

"That might not sound like much, but in some regions the deformation is significantly greater – up to 1 mm (0.04 inches) per year over the Arctic Ocean, and 0.4 mm (0.016 inches) per year in the South Pacific.

"Overall, the researchers say purely satellite-derived assessments of sea level rise for the period could have underestimated barystatic sea level rise by as much as 8 percent – which is definitely something we need to think about in the future, especially this hidden variable will only become more significant as the world gets hotter and sea level rise accelerates... Absolute sea level in the Gulf of Alaska has been falling, contradicting a global trend..."

Considering that it has been proven that with the melting in the last ice age that it increased sea levels some 180 to 400ft in most places on the globe. The fact that we still have massive ice caps and available ice to add to the ocean depths does not seem to register with some people who think that the constantly changing climate is somehow a fraud cooked up just to bash THEIR Industries.

No, it is a matter of the fact we have been charting the changes for so long and are now, with the increase in extreme industrial pollution output and high population that we are increasing heat across the globe. This is having exactly the foretold effects of worse storms, harder winters due to more water evaporation and sea water temps.

Everything they said would happen due to climate change in the 60s and 70s is happening, just as they said it would even with their non-computer simulations they could do at the time.

They have been proven correct. Anti-change folks: totally debunked

So atrophied brain Antigoracle's argument is if you ever used oil, then you are tainted, and must let the oil companies do whatever they want forever. It must be really hard for you having a only a tiny, atrophied Republican troll brain. By your specious (that means bad) argument, we would never be able to change our ways after having discovered any problem.

Here is how to stop burning fossil fuels:

1. Never vote Republican, they are owned by the fossil fuel industries.
2. Never listen to morons who rely on profanity and animal noises to make their points and are totally clueless when it comes to science.
3. Use LED lights.
4. Consider buying an electric vehicle.
5. Consider buying a solar array.
6. Vote for Democrats who are genuinely concerned about global warming and support ending tax breaks for fossil fuel companies, a huge carbon tax and renewable energy research.
7. Learn about global warming from actual climate scientists, not liars and morons.

Marky Mark's simple mind requires a simple world.

"The DNC's vote to ban contributions from fossil fuel companies in June was a big win for progressive activists fighting for an aggressive stance on global warming. It took only two months for the party to backtrack.

"Last week, Tom Perez, the party's top official, pushed through a measure undoing the commitment at the request of organized labor, whose leaders fear that some climate change measures could come at the cost of good-paying jobs. "After hearing concerns from Labor that this was an attack on workers, this resolution acknowledges the generous contributions of workers," the DNC said in a statement, "including those in energy, who organize and donate to Democratic candidates."

"At the heart of the conflict are the two million plus jobs in the oil, gas and coal industries that could disappear as the world moves to clean energy sources. Many of those positions pay six-figure salaries..."

The science of measuring the plastic deformation of the crust and the asthenosphere due to applied loads is over a century old. Studies of the deformation of the ocean basins when the oceans were 130 m lower during glacial periods and 10 m or more higher during previous inter-glacials were done quite a while ago, so there were plenty of tools and expertise for the more recent work.

C) realize that rising sea levels at 1/8 inch per year dwarf the ocean floor sinking by a factor of 31x. It will take millennia to adjust
-which contradicts

"[B]ecause satellite altimetry observes sea level in a geocentric reference frame, global mean sea-level estimates derived from altimetry will not observe the increase in ocean volume due to ocean-bottom subsidence, and hence, they may underestimate [global mean sea-level] rise," the researchers explain in a new paper."

-which say they're concurrent.

So barky does indeed need to provide something other than bluster to justify his assertion that 1) subsidence is a universal phenomenon and that b) he seems to think it happens a lot slower than ocean volume increases.

Hate to burst your bubble, HAWW...HEE...HAWW...HEE.. and and have been, for the last year, calculating elastic plate equations for a project I'm working on. ........

The barakn jackass brays.
This jackass is working on equations!

There may be a few minor surprises in store, but nothing major


Famous last words for mainstream science, I don't know how you guys get out of bed with the weight of all that hubris...

We simply do not have enough data of ocean floor activity to make an estimate with great confidence.

15 meters or bust man! Go climate deniers go! Yeah, we understand how stupid you are! Yeah, you're going to lead us out of all of this and make sure that we all have great jobs! I can't wait to see it! So why not? 15 M or bust! Damn everybody else. Full Speed Ahead to 15 meters! ???

Did I get it right my climate-denying friends?

This is the jackass who boasted about riding into NYC, spewing CO2 all the way, just to snort the methane emanating from the rectum of his FALSE "PROFIT" Al Gore, blocking traffic for hours and dumping garbage on the streets.
Damn everybody else. Full Speed Ahead to 15 meters! ???

Your ignorant replies show no one used the easy search term I dropped, glacial isostatic rebound, which you could have used to fill up the vast holes in your knowledge. But in short - rock is not very compressible, so when a large load is place on the surface, the rock below can't accommodate it by getting smaller. The lithosphere is fairly stiff, so it mostly responds by bending downward, but in order for that to happen, the asthenosphere has to move out of the way, mostly by moving sideways and bulging up further away. The asthenosphere is (mostly) not molten rock or magma that could flow like a river but solid rock that is hot enough to deform plastically, on a timescale of millennia. When the load is removed, the asthenosphere moves just as slowly back in and the lithosphere snaps back up. The fact that Scandinavia (and nearby ocean bottom) is still rising some 10,000 years after the ice sheet melted is an indication of how slow this process is.

The jackass, antigoracle...aka..Oil Industry Boot Licker, brays again.
This is the jackass whose argument from his rectum is if you use oil, you are a hypocrite for complaining about global warming. This totally ignores the fact that many of us still don't have good alternative to oil and the oil industry is doing everything they can to prevent alternatives to oil from being created and used. The oil industry makes tens of billions of dollars a year in profit, buys a bunch of corrupt Republicans, and that that jackass antigoracle wants you to walk to work. Did I get it right my Chicken Shit Jackass?

So WTF has antigoracle ever done to combat global warming? He's too busy being a Oil Industry Boot Licker. I listed seven steps I have taken in my comment above to fight Global Warming. Antigoracle's troll brain plan is to lick boots, right my Chicken Shit Jackass?

And a special note to Otto. The researchers that you quoted saying
global mean sea-level estimates derived from altimetry will not observe the increase in ocean volume due to ocean-bottom subsidence, and hence, they may underestimate [global mean sea-level] rise
...are the ones that provided the 8% average number that they believe the sinking is underestimated by. "Average" implies that they averaged the underestimated sinking over ALL ocean floors, so when you say
-implying that this was happening everywhere when obviously, not
... you just sound like an idiot. Do you not understand the concept of an average? If you are going to supply numbers and then freak out when someone does some obvious math with them, maybe you shouldn't have supplied the numbers in the first place.

Barky said
So instead an average of .004 inches it will be sinking an average of .00432 inches. That means that sea level rise will dwarf that by only a factor of 28.9x?
-And then he said
Do you not understand the concept of an average?
Well I do know you cant extrapolate a universal absolute of 29.9x from only 2 simple averages.

And you need to explain why you still think
the asthenosphere moves just as slowly back in and the lithosphere snaps back up
-when the researcher tells you that

"[B]ecause satellite altimetry observes sea level in a geocentric reference frame, global mean sea-level estimates derived from altimetry will not observe the increase in ocean volume due to ocean-bottom subsidence, and hence, they may underestimate [global mean sea-level] rise,"

-???

HE is telling you that the floor is moving as fast as the water volume is changing.

How come?

Poor jackass is paying the evil oil companies to burn their fuel and then brays about it.
Poor jackass, so cares about gloBull warming, but cannot be inconvenienced to take public transportation.

Once again, it's not my job to explain to you what an average is.
"[B]ecause satellite altimetry observes sea level in a geocentric reference frame, global mean sea-level estimates derived from altimetry will not observe the increase in ocean volume due to ocean-bottom subsidence, and hence, they may underestimate [global mean sea-level] rise,"

No, that's not what he is telling me, or anyone else. If you are going to so severely misconstrue what other people have said, you are not worth my time.

Ahaahaaa so you cant explain

"global mean sea-level estimates derived from altimetry will not observe the increase in ocean volume due to ocean-bottom subsidence"

-with your "timescale of millennia" crap.

What a blowhard.
