QuoteSea level rise will swallow Miami, New Orleans, study finds
Say goodbye to Miami and New Orleans. No matter what we do to curb global warming, these and other beloved US cities will sink below rising seas, according to a study Monday.
But making extreme carbon cuts and moving to renewable energy could save millions of people living in iconic coastal areas of the United States, said the findings in the October 12 edition of the Proceedings of the National Academy of Sciences, a peer-reviewed US journal.
Scientists have already established that if we do nothing to reduce our burning of fossil fuel up to the year 2100, the planet will face sea level rise of 14-32 feet (4.3-9.9 meters), said lead author Ben Strauss, vice president for sea level and climate impacts at Climate Central.
The big uncertainty is the issue of when.
"Some of this could happen as early as next century," Strauss told AFP.
"But it might also take many centuries," he added.
"Just think of a pile of ice in a warm room. You know it is going to melt, but it is harder to say how quickly."
To bring this issue home for people in the United States, the study pinpoints at-risk land where more than 20 million people reside.
The authors projected business-as-usual carbon emissions, in addition to the complication of the melting West Antarctic ice sheet, a process some experts fear is irreversible.
They also considered what might happen if the world were to make a big turnaround, reaching peak carbon emissions by 2020.
This radical scenario would have to occur far earlier than the current aim of some world powers to peak by 2050, said Strauss.
An online tool at choices.climatecentral.org allows users to see the impacts on various US cities. A global version is expected in the next month, Strauss said.
Too late?
The tool shows which US cities may face "lock-in dates beyond which the cumulative effects of carbon emissions likely commit them to long-term sea-level rise that could submerge land under more than half of the city's population," said the study.
"Norfolk, Virginia, for example, faces a lock-in date of 2045 under a scenario of unabated carbon emissions."
For cities like Miami and New Orleans, the limits are already exceeded.
"In our analysis, a lot of cities have futures that depend on our carbon choices but some appear to be already lost," Strauss said.
"And it is hard to imagine how we could defend Miami in the long run."
Miami's low elevation and porous limestone foundation mean that sea walls and levees will not help, he said.
The state of Florida has the most number of big cities at risk from sea level rise, holding 40 percent or more of the US population living on potentially affected land.
After Florida, the next three most affected states are California, Louisiana and New York.
One beloved American city, New Orleans, home to jazz music and some of the nation's most beloved cuisine, is already sinking.
"New Orleans is a really sad story," Strauss said.
"It is a lot worse looking than Miami."
New York is also in peril, and under a worst-case scenario, the city could be consigned to an un-livable future by the year 2085, according to the study.
But strong action—the kind that would reduce carbon emissions in the year 2050 to levels that more closely resemble those seen in 1950—could make a difference.
A total of 14 cities with more than 100,000 residents could avoid locking in this century, including Jacksonville, Florida; Chesapeake, Norfolk, and Virginia Beach in Virginia; and Sacramento and Stockton in California.
"We were really trying to show what the consequences of our carbon choices are going to be," said Strauss, whose study was co-authored by the Potsdam Institute for Climate Impact Research in Germany and edited by renowned NASA climate scientist and author James Hansen.
According to earth scientist Michael Mann, a well-known author on climate change, the latest findings are a "useful contribution to the literature."
The study provides a "better quantification of the detrimental impacts of the magnitude of sea level rise we may commit to in the decades ahead if we continue with business-as-usual policies of fossil fuel burning," said Mann, who was not involved in the research.

Reminds me of Lex Luthor's California earthquake scheme. Trick is figuring out where the new beachfront will be.
We already knew this
It is not possible to take action against global warming. Those who need to make the sacrifices will unlikely reap the benefits. The current generation living in, say, the interior provinces of mainland China will need to refrain from buying cars so that half a century from now, the city of Miami will not sink below sea level? That simply won't happen. Forget it, it is a lost cause.

If China's government takes action to keep HK, Shanghai and other coastal Chinese cities from also sinking, maybe.

Bullshit. Sea level rise isn't going to happen so rapidly that millions of people are going to drown. Save billions of dollars in property, maybe, but probably not a single life.

Thing is, even if China's government is willing to do it, it is meaningless unless everybody else in the world also does it. "It" being things like stop buying cars, stop generating electricity using coal and oil, etc. I don't think it will happen.

I don't think it will happen either, but was pointing out that inland Chinese could be made to comply even though they weren't the ones directly affected.
This is not as severe a crisis as it first appears. New Orleans will be given new life in space.

Agreed. There's no excuse for it really.
Luckily, the ocean will take care of the problem.

Okay but that's just poor word choice from the writer of the news article. The abstract refers solely to saving land area populated by millions.

While of course gradual sea level rise is not going to drown a bunch of people, the idea that the planet is going to go through this radical a change, with literally hundreds of millions of people needing to relocate, without a commensurate radical political, economic, and military reaction is insane.
Millions will die in associated wars, famine, and economic messes where the poor simply cannot react in a controlled manner. We are starting to see some of that already. Of course, the dumbasses will blame every other possible variable other than climate change so they can continue to destroy the planet that Jesus gave them with a clear conscience.

This is a incredibly dishonest argument.
The idea that the only possible options are "do nothing" and "stop buying cars" is just an excuse to, well, do nothing.
There is plenty that can be done given the political will to act.

Don't care. If we act and China doesn't then we can shame and humiliate the Chinese government for manufacturing an international meltdown. They love being made to look idiotic publicly. Anyway technology is the answer and I think we are on our way to solving it. Maybe even around the same time Miami disappears beneath the waves and Dorsey only has one College Football team left to root for.

China will say they have done a lot. Whether they will actually do a lot is another story. Another crucial difference between China and the west is that the population is quite indifferent to global warming. It is not just the government that you have to convince.

Contrary to popular perception, the Chinese Communist Party isn't omnipresent or omnipowerful. Sure, they can enforce quite a few things, but not everything. Reducing carbon emissions will not be a priority.

That's totally unrealistic. The boat isn't terribly expensive. The space to park it is. And the membership fees for one of those clubs is insane. Sailing is for the super rich only.

There is indeed a market for the yacht club memberships. It is considered a speculative vehicle. But only for the super-rich. I have no idea, but I fully expect such a membership to cost at least six US$ figures. Probably a lot more than that. Certainly not for plebs or wage slaves.
