Sea Level Rise may displace up to 16 million Americans by 2100, according to researchers from the University of Georgia. But the study ignores history, technological progress, and the unreliability of climate models.

Sea level rise projected to displace 13 million in U.S. by 2100

A new study by University of Georgia researchers could help protect more than 13 million American homes that will be threatened by rising sea levels by the end of the century.

It is the first major study to assess the risk from rising seas using year 2100 population forecasts for all 319 coastal counties in the continental U.S. Previous impact assessments use current population figures to assess long-term effects of coastal flooding.

The study is based on analyses by Mathew Hauer for his doctoral work with the UGA Franklin College of Arts and Sciences; Deepak Mishra of the UGA department of geography; and Jason Evans, a former UGA faculty member now with Stetson University. It was published March 14 in the journal Nature Climate Change.

Based on year 2100 population forecasts, the authors report that a 6-foot sea level rise will expose more than 13 million people to flooding and other hazards from rising seas. Florida faces the most risk, where up to 6 million residents could be affected. One million people each in California and Louisiana also could be impacted.

Adaptation strategies are costly, and these are areas of especially rapid population growth, so the longer we wait to implement adaptation measures the more expensive they become,” Hauer said.

The abstract of the study;

Millions projected to be at risk from sea-level rise in the continental United States

Sea-level rise (SLR) is one of the most apparent climate change stressors facing human society1. Although it is known that many people at present inhabit areas vulnerable to SLR2, 3, few studies have accounted for ongoing population growth when assessing the potential magnitude of future impacts4. Here we address this issue by coupling a small-area population projection with a SLR vulnerability assessment across all United States coastal counties. We find that a 2100 SLR of 0.9 m places a land area projected to house 4.2 million people at risk of inundation, whereas 1.8 m affects 13.1 million people—approximately three times larger than indicated by current populations. These results suggest that the absence of protective measures could lead to US population movements of a magnitude similar to the twentieth century Great Migration of southern African-Americans. Furthermore, our population projection approach can be readily adapted to assess other hazards or to model future per capita economic impacts.

Read more:

Obviously anyone in immediate danger of flooding needs to address the problems they face. But is it really wise to spend large sums now, to protect property against a future rise in sea level, which might never happen?

Sea level rise has not accelerated, as climate models predicted. Until climate models demonstrate reliable predictive skill, it would be unwise to use them as the justification for large expenditures of public money.

For example:





Even if the predicted sea level rise occurs, every year that preparations are delayed, substantially reduces the real economic cost per capita of action. Our economic, our engineering capabilities are growing geometrically. For example, new construction systems, such as gigantic “concrete printers“, robotic machines which create large continuous structures using scaled up 3d printing technology, are already being prototyped. Such robotic machines will dramatically cut the cost of building sea defences, when they become mainstream.

New York City has been able to keep up with sea level rise since it’s beginnings with simple technology, there is no reason to think future inhabitants won’t be able to.

Long before the year 2100 many more than 16 million Americans will have been displaced, and will have taken up residence in Heaven.
A much greater number will be in Hell, which is still classified as a displacement.

You have a good part of the equation identified. Another part of the equation is all the people that will be moving into those same beach houses and building even more – right up to 2100. They anticipate a significant growth in the beach population that later has to migrate. If truly the seas were rising that fast, that shouldn’t happen. Unless the residents decided to build levees or dikes to protect their communities. That has been done before – well before 21st Century technology.
As is often identified on this site, the use of “could” shields the conclusion from serious discussion. It doesn’t mean anything since the premise is weak. Along the lines of “If my aunt had balls, she’d be my uncle.” Yup, but she doesn’t.

So speaking of German; when I was studying it for a year (so I could read Einstein); my German Prof told us a story about a rather famous German Poet, who wrote a very controversial poem (at that time), but then chickened out and decided it was too risky to publish (no not risqué).
But he came up with a clever idea and he went through the poem, and everywhere the word “Freiheit” occurred, he simply replaced it with the word “Freude”, and then published it.
Can any scholar confirm or pooh pooh that story.
If I’m not mistaken (often the case) a musical version of it was actually once performed in public with the original word restored. I think I even heard that performance. Might have been Seiji Ozawa with the sword in his hand.

I’m quite sure these figures are accurate – IF – there is a six foot rise in sea levels.
We are going through this in my city who is in the process of uprooting suburbs for an expected inundation of 1 Metre by 2115.
However I have taken the trouble to do all the background reading. Of course there would need to be a marked acceleration of sea level rise to achieve 100 cm in 100 years.
The catch is that only two of their sources mention the current acceleration of sea level rise around here and one explicitly states there has been no acceleration yet.
For the record, it is about 1.7mm per year where it has been since records began. That is – no acceleration has yet occurred – oops! – but that still does not stop the Christchurch City Council moving towards getting people off the (yet to be) wetlands.
Of course this is only part our council’s process to make my city into the worlds most sustainable city.

Roger. This stuff is mostly based on climate models that have never ever made one single correct (“skillful”) prediction. It is, of course, largely nonsense. However, these guys do have a point. Although population growth worldwide has moderated considerably from that experienced in the past century, it’s still impressively high. At the current 0.7% a year, the US will have 500,000,000 people in 2100. And a lot of them will doubtless want to live (too) near the ocean. It will, predictably, be someone else’s fault when a combination of subsidence, sea level rise, tides, and a storm with 100 plus kph winds, storm surge and prodigous rainfall wipes out their home.
Measuring sea level rise is quite difficult, I’d view that 1.7mm per year with considerable skepticism. It might really be half that. Or twice that. And over the course of a century, it might accelerate or decelerate a bit. On top of that, folks generally underestimate the worst case scenario for any given location. And the world likely won’t end in 2100. Many towns in Europe have been in the same place for a thousand years. Even in the new world, 200 year old or more buildings are still in use. All in all, prudence would probably dictate that stuff that doesn’t have to be waterfront either be bunkerlike, mobile, throw away, or built WELL back from the ocean.

Roger, you say: “Of course there would need to be a marked acceleration of sea level rise to achieve 100 cm in 100 years.”
They are actually talking about 180 cm (1800 mm) in under 90 years, so more than 20 mm per year, 10 times the rate that we’ve seen over the last 100 years of dumping massive amounts of CO2 into the atmosphere.
Alarmists are getting on Exxon Mobil’s case because in the 1980s some engineers decided to factor in a 20 mm/year sea level rise into the design of an offshore oil platform, allowing for 500 mm rise over the 25-year life of the platform. This “proves” that Exxon knew about the danger of climate change way back then.
Of course, sea levels only rose about 50 mm over the life of the platform, so those engineers wasted a lot of money by believing the alarmist predictions.

It’s the math that gets me. 2100 is 84 years from now. 0.9 meters is 900mm. So 900/84 gives you 10.7mm/year. Have we’ve seen a 4mm year yet? No! So, how are we going to get to 10.7mm? The physics is just not there.

2100 will arrive in around THREE GENERATIONS of our descendants. In only ONE generation of mine our family members have dispersed across the globe, relocating on three or four separate occasion within those countries each.
This was by CHOICE, not enforcement.
The alarmist stance always seems to imply the catastrophe will be happening ‘tomorrow’ and will be insurmountable. I tend to err on the side of the people – who have, and always will, do what they need to do.

The basis of their scaremongering is that the population in the threatened regions is increasing, so there will be even more people displaced, This means that they assume that people will be moving into a region that is at serious risk of flooding.

Eventually, we will have a better grasp of glacial isostatic adjustments and absolute vs. relative sea level changes. To use this post’s reference to The Battery in New York as a starting point, consider that most of the US coastline is moving up or down over time due to glacial rebound, tectonic forces and/or subsidence from sediment compaction and pumping of underground fluids.​
In 2006 NOAA estimated that the Mean Sea Level Trend at The Battery was 2.77 mm per year of which the “Vertical Land Movement” was -1.22 mm per year. Data taken from Table 1 at

In my part of West Virginia (the Ohio River Valley near Wheeling, WV), one can climb to the top of the bluffs overlooking the valley and see that one is actually looking across a dissected plain. Every hilltop is the same height as far as the eye can see, with the Ohio River about 450 feet below. The land has risen with the retreat of the glaciers, and the Ohio and its tributaries have cut deep into the rebounding earth.
The photo in this link gives one a good idea of the terrane. It’s looking west from Moundsville, WV, just a few miles south of Wheeling on the Ohio.

Based on year 2100 population forecasts, the authors report that a 6-foot sea level rise will expose more than 13 million people”
Although I did not shell out the $32 for the study, the actual abstract seems to indicate 13 million people would be living in housing “at risk” after a 6 foot rise in sea level, assuming no-one sees K-Kenny c-coming to k-kill them and current population trends are projected forward. apparently has no problem inflating that by a factor of 2+ by equating “people” with “homes”.

Even changing the program based on predicted flooding to eliminate all new development would reduce taxpayer liability and make “homeowners” insurance unavailable leading to lenders refusing mortgages. If Hillary wants to build a house on the coast and accepts the risk I don’t care.
Of course big rises in sea level are not predicted by historical data and coastal rise or fall acerbates some problem examples.

March 14, 2016 4:54 pm

Maybe I’ve got the math skills of a cat, but am I wrong? Variations around 2.5 mm/y to 3.5 mm/y are … 0.25 to 0.35 meter per century or from 10 to 14 inches of average global seal-level rise by 2116? or only 8 to 11.5 inches by the year 2100?
I thought the authors were propounding 0.8 to 1.8 meters! Did they use different sea-level statistics than all the ones so far cited and listed here? Has anyone yet found a nonlinear sea-level rise correlation?
PS: the reason for the Crescent City sea-level subtle drop is very likely to the Pacific (or Juan de Fuca) plate submerging under the North American plate, causing buckling along the great Cascadia fault. The rising coastal plate hides the sea-level rise because the plate is rising faster. At least I can do that math.

Accurate measurement of tectonic changes in tide gauge elevation does need to be done. But it’s MUCH harder to do than most folks think. You’re talking changes of the thickness of a few sheets of paper per year. Relative to satellite positions that are a bit uncertain. Using radio signals that are subject to variable ionospheric delays. And there are some technical geometric problem with the vertical component of GPS measurements that make it a bit harder to measure than the horizontal components.

March 15, 2016 11:08 am

Mark W: The reason why GPS units don’t display elevation and wander around a lot if they do is a geometry thing. Unlike your eyes which see angles well and distance poorly, GPS sees distance really well and angles not at all. So the GPS needs to get the distance to several satellites and try to solve for a unique position that accounts for the distances to all of the satellites. When the GPS satellites are near the horizon, there are a lot of elevations that can be a pretty good fit to the set of distances being observed. To resolve elevation well, at least one of the satellites needs to be high in the sky. Unfortunately, most satellite passes don’t get very high in the sky. Passes directly overhead that have a lot of elevation information are quite rare. Throw in all the miscellaneous errors that can louse up a calculation, it turns out that there is a lot more x-y (lat-lon) information to use to average out errors than z (elevation) information.

March 14, 2016 5:04 pm

Perhaps I missed it, at least in the Abstract (pun intended), but did the paper posit a figure for the projected level to which the sea is expected to rise? I can understand that, IF the sea rose 6 ft (1.8 m), then there would be a greater effect than 3 ft, but there also would be a greater effect if it rose 9 ft. Of course, this all would be moot if a 20 km diameter asteroid or comet hit the earth. Since it would have (assuming such an object hit the earth) a better than 2 to 1 chance of hitting oceans than land, that would raise the land-measured level of the sea much more than 6 ft, at least temporarily. Shouldn’t we be building ships to evacuate Earth? /sarc off…

Aha! Another question.
I use a sea level rise of 8 inches/century because that is what has been going on for the last 4,000 years, at least. (not GIA corrected, of course)
So your 6 foot rise will take exactly 900 years. Note that is eustatic sea level rise.
YMMV due to glacial rebound, tectonic uplift, subsidence, mining activities, landfill operations, asteroid strikes, etc.

> Is the sea eternally “going to rise” six feet, but never actually rise six feet?
Apparently the answer would be “Yes”.
OTOH, something to file away mentally. There is considerable evidence that the high stand of the last interglacial 120,000 years ago was at least 5 meters (16 feet) above current sea level. No one has the much idea why the current interglacial might not eventually achieve the same level with or without human intervention.

It was not blind male prejudice that gave the same root to ‘hymen’ and ‘hysteria’.
The case is often made that women were deliberately excluded from the sciences that involved rational process instead of blind prejudice. When one looks at today’s feminists, it doesn’t look like such an unreasonable decision.

Seal levels are terribly dependent on warming. Just half a degree increases the seal food index exponentially, and the seal level will therefore rise accordingly, till we are awash with seals, and the ‘Canadian Club on the Rocks’ remedy will have to be implemented, along with sealskin mittens being featured on the catwalks.
I blame it all on Thatcher, for making strident sealfemales claim their rights to have unlimited pups, instead of dying heroically pupless, from starvation.

In 1990 I began designing features for a $28.2 million flood control project for a city at the mouth of the Chehalis River in Grays Harbor WA. The design flood still water level was caused by a spring tide, coincident with a low barometric pressure and high river flow.
Global warming and sea level rise was in the news back then, so we assessed the threat, determined it was political science and designed the level to accommodate one foot of sea level rise over the next century. This was the observed historic rate of sea level rise based on tide gauges in the area.
The project has provided reliable flood protection since it was completed in 1996 and there are no plans to increase the levee height.
NOAA ‘s sea level trends consistently show a constant and generally trivial rate of sea level rise based on tide gauge data going back to 1854.
Sea level rise is not accelerating presently, and has been constant since the 1850’s. This is obvious proof that the planet is not warming catastrophically and the AGW science is a FRAUD!
There are no massive construction projects building new levees or raising existing levees near our coastlines and estuaries. The politicians obviously know that AGW and sea level rise is not reality.

You surely know more about your local conditions at Grays Harbor than I do. But did you take the Cascadia fault system into account? A lot more is known about subduction zones now than was known in 1990. I think the current best guess is that it may well let go during the current century and that it will probably drop much of the NW coast three feet or more when it does. Of course if a magnitude 9 earthquake does occur there, a bit of river mouth flooding may not even reach the top 20 on your list of problems.

Back in the 1960s the Warmists projected that by the year 2000 the sea level could rise by 10 feet, enough to put NYC and DC underwater. They also projected that catastrophic melting of Greenland and Antarctica would cause sea levels to rise another 200 feet over the next 200 years. At 1 foot per year since 2000, I figure that we should already be at 26 feet of sea level rise of the Warmists were correct.
And as they say, it’s just physics, and those physics have been well understood for 100+ years, so they certainly shouldn’t have been off by a factor of 100.

Why is it the uneducated people from whom we are descended were able, thousands of years ago, to survive very rapid sea level rise in excess of hundreds of feet but modern society can’t tolerate a matter of inches of rise? Is it that people think this could happen over night if it even happens at all? Recall too there is no evidence that accelerated rise is even happening. The notion comes from questionable models, not observation. How many more decades of failed sea level rise fear mongering must we endure before the Department of Justice investigates these claims and prosecutes the perpetrators for unsubstantiated mayhem and tax-wasting alarmist propaganda?
Ask these death wishers why it is not possible for couples to take long walks on the sandy beaches of Doggerland while listening to Kenny G on the radio. It is because there was once a real change of climate that flooded the land bridge between England and Europe, and there has not been a similar event in the time since and won’t be one again any time soon. The same event that flooded Doggerland made it possible for my house to be built on a glacial bench left behind by the Cordilleran ice sheet here in Washinton State – home of the famous Scablands. We know in this state what real climate change looks like – we’re surrounded by the very dramatic results of climate change.

“Sea Level Rise may displace up to 16 million Americans by 2100, according to researchers from the University of Georgia. But the study ignores history, technological progress, and the unreliability of climate models.”
For the Eastern Seaboard of the US many projections of sea level change ignore geological processes that are not related to the rise in sea level.
Along much of the US east coast, the land is sinking and has been sinking since the continental glaciers melted at the end of the last ice age, about 18,000 years ago. The mantle rock displaced by the weight of the ice in Canada had created a ‘fore-bulge’ in an arc that extends from offshore to mid-continent, intersecting the east coast. Ever since the glaciers melted and the weight of ice was removed, the fore-bulge has declined, resulting in the sinking of the land along the coast.
Just as climate fluctuates naturally over decades, centuries and millennia, so does sea level fluctuate. During the Holocene Climate Optimum (Hypsithermal) about 5,000 years ago, sea level was about 7 feet (2 meters) higher than now. During the last interglacial about 130,000 to 105,000 years ago, sea level reached about 30 feet (9 meters) higher than now. These ancient high sea level stands occurred without any help from mankind.
During our present warm interval between glacier advances, sea level will continue to rise a little faster during warm periods and a little slower during cold periods, whether or not we act to control climate.
The ancient Mayas sacrificed their children to appease the rain gods, but the climate of the Yucatan changed in spite of their efforts. ( Some modern nations seem keen to sacrifice the economic well-being of present and future generations to keep climate and sea level stable. Those nations will decline as did the Mayans, and other nations will rise in power and wealth. This must happen because the wealth of modern nations relies on cheap energy, traditionally coal and more recently methane (natural gas).
History repeats itself, but never in the same way. The old way to national rise and fall of nations was by warfare and conquest, discovery and technology. Modern America, Canada, and Europe have invented a new way to alter the relative wealth of nations: economic decline by government policies and law based on semi-religious beliefs about mankind’s relationship with Nature. If there was any doubt about the religious basis for catastrophic climate alarmism, the present Pope has revealed its true ideological foundations.
We are witnessing the end of the beginning of the decline in American-European civilization and the ascendancy of China-Southeast Asia.

Boston sea level rise impacts since 1630:
With SLR of 1.7 mm/yr, starting in 1630 Boston was able to ADD 3 acres/year to its area using hand labor and horses.
Now, with modern earth-moving machinery and advances in design, Boston is doomed to drown with SLR at 2.8 mm/year, about half of which is local subsidence.
In 1630, Boston area = 783 acres
Landfill additions- Back bay, west cove, mill pond, great cove, south cove
Total as of 2013= 1904 acres
Land area gain per year = (1904 – 783)/(2013 – 1630) = 3 acres per year
Sea level rise 1630 – 2013 = 650 mm, or 1.7 mm/year
(Note- USGS estimates SLR of 1 mm/year over last 2000 years
(Note- Boston subsidence is estimated at 1.5 mm/yr

March 14, 2016 6:30 pm
Sea level rates up to three times the global mean rate are being observed in the western tropical Pacific since 1993 by satellite altimetry. From recently published studies, it is not yet clear whether the sea level spatial trend patterns of the Pacific Ocean observed by satellite altimetry are mostly due to internal climate variability or if some anthropogenic fingerprint is already detectable. We show that subtraction of the IPO contribution to sea level trends through the method of linear regression does not totally remove the internal variability, leaving significant signal related to the non-linear response of sea level to El Niño Southern Oscillation (ENSO). In addition, by making use of 21 CMIP5 coupled climate models, we study the contribution of external forcing to the Pacific Ocean regional sea level variability over 1993–2013, and show that according to climate models, externally forced and thereby the anthropogenic sea level fingerprint on regional sea level trends in the tropical Pacific is still too small to be observable by satellite altimetry.
Furthermore, regressed CMIP5 MME-based sea level spatial trend pattern in the tropical Pacific over the altimetry period do not display any positive sea level trend values that are comparable to the altimetry based sea level signal after having removed the contribution of the decadal natural climate mode. This suggests that the residual positive trend pattern observed in the western tropical Pacific is not externally forced and thereby not anthropogenic in origin. In addition the amplitude of the sea level spatial trend pattern from regressed CMIP5 MME is low over the altimetry period in the tropical Pacific. This amplitude is significantly lower than the expected error in trend patterns from satellite altimetry (in the order of 2 mm yr-1 to 3 mm yr−1, Ablain et al 2015, Couhert et al 2015) and suggest that satellite altimetry measurement is still not accurate enough to detect the anthropogenic signal in the 20 year tropical Pacific sea level trends.

March 14, 2016 6:37 pm
Global sea levels have been rising through the past century and are projected to rise at an accelerated rate throughout the 21st century. This has motivated a number of authors to search for already existing accelerations in observations, which would be, if present, vital for coastal protection planning purposes. No scientific consensus has been reached yet as to how a possible acceleration could be separated from intrinsic climate variability in sea level records. This has led to an intensive debate on its existence and, if absent, also on the general validity of current future projections.
Tide gauges provide the most reliable measurements, and best data to assess the rate of change. We show as the naïve averaging of all the tide gauges included in the PSMSL surveys show “relative” rates of rise about +1.04 mm/year (570 tide gauges of any length). If we consider only 100 tide gauges with more than 80 years of recording the rise is only +0.25 mm/year. This naïve averaging has been stable and shows that the sea levels are slowly rising but not accelerating. …The satellite altimetry returns a noisy signal so that a +3.2 mm/year trend is only achieved by arbitrary “corrections”. We conclude that if the sea levels are only oscillating about constant trends everywhere as suggested by the tide gauges, then the effects of climate change are negligible, and the local patterns may be used for local coastal planning without any need of purely speculative global trends based on emission scenarios.

“If we consider only 100 tide gauges with more than 80 years of recording the rise is only +0.25 mm/year. This naïve averaging has been stable and shows that the sea levels are slowly rising but not accelerating. We also show as the additional information provided by GPS and satellite altimetry is of very little help. Computations of “absolute” sea levels suffer from inaccuracies with errors larger than the estimated trends. The GPS is more reliable than satellite altimetry, but the accuracy of the estimation of the vertical velocity at GPS domes is still well above ±1 mm/year and the relative motion of tide gauges vs. GPS domes is mostly unassessed.”
Thanks for that link, Kenneth. Good information and much more realistic than the stuff we are usually fed.

Projected sea level trends of the representative concentration pathway 4.5 (RCP4.5) scenario for 20-, 50-, and 100-yr intervals grow from being largely dominated by internal variability on shorter time scales to being the dominant sea level signal on long time scales. The internal variability is estimated by calculating overlapping trends for the various time scales on the regional sea level control run output from each model. When compared to the ensemble spread of the RCP4.5 scenario trends, the internal variability remains a substantial portion of the spread even after 50 years.
Numerous studies have linked recent high sea level trend patterns in the WTP [Western Tropical Pacific] (global mean removed) to trade wind forcing [e.g., Carton et al., 2005; Kohl et al., 2007; Timmermann et al., 2010; Becker et al., 2012]. Merrifield [2011] used tide gauge data to show that the regional sea-level rise rate increased abruptly in the early 1990s shortly before the start of the TOPEX/Poseidon altimeter record, and that the trend shift matched an enhancement in reanalysis trade wind speeds averaged across the tropical Pacific. Numerical model simulations [Merrifield and Maltrud, 2011; McGregor et al., 2012] confirm that the steady intensification of the trade winds largely accounts for the amplitude and spatial pattern of WTP sea-level rise since the early 1990s.
Tide gauge observations in the western tropical Pacific provide a 60 year long record that strongly reflect trade wind forcing on multidecadal time scales. Similar variations are also exhibited by the dominant climate indices in the tropical Pacific. The recent high sea level rise rates in the WTP beyond the global mean rate are a result of increasing trades, which occur when the PDO (SOI) index exhibits a negative (positive) trend.

“Ongoing land reclamation projects have increased Singapore’s land area from 581.5 km2 (224.5 sq mi) in the 1960s to 719.1 km2 (277.6 sq mi) in 2015, an increase of some 23% (130 km2). The country is projected to grow by another 100 km2 (40 sq mi) by 2030.[95] Some projects involve merging smaller islands through land reclamation to form larger, more functional islands, as has been done with Jurong Island.”

We are now up to 384 Tide Gauges that are co-located with a GPS station (operating for long enough to provide useful information).
This table shows the Vertical land movement (V_GPS) for the stations.
Unfortunately the GPS station ID name is not the best to know where it is so one has to use this table as well to match up the ID to the location.
Battery Park/Sandy Hook (SHK2, SHK5) is actually sinking by about 1.6 mm/year to 3.6 mms/year so the tide guage at Battery Park measuring sea level increase of 2.84 mms/year is essentially measuring no change in real sea level at all.

The computer model overlooked one critical factor–there’s no source for that much water! As Niklas Morner has pointed out, even when warming was 20 times as intense as recently and there were huge ice sheets covering large masses of land, the rate of sea level rise was only about one meter per century. Today with a puny rate of warming for 20 years, no warming for 18 years 9 months, the Antarctic ice sheet growing (not melting), temperatures in Greenland lower now than in the 1930s and 1940s, and no glaciers at the North Pole, the most sea level rise we can expect is about 7 inches per century.

“Claim: Sea Level Rise Could Displace Millions of US Citizens”
And a few million non-citizens 🙂

Quote the abstract
whereas 1.8 m affects 13.1 million people—approximately three times larger than indicated by current populations.
So they are saying that knowing the coast will submerge, double the current population will move there and then get displaced.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Sheesh, what would you expect.

Sea level rise is local: it depends on whether the land is rising or falling, and how fast.
The recent (~140 years) linear trend certainly does not follow the Keeling Curve. A straightforward extrapolation would put the mean sea level in 2100 at The Battery (at the seaward tip of Manhattan where the largest number of people would be ‘affected’) about 24 cm (9-1/2 inches) higher than the current sea level – less than a third of the anxiety-producing figure of 0.9 m.

I’m sure people living in areas where sea level is rising at 18mm each year would already be on the move. I can’t imagine where this would be happening though. Here it’s been rising at 1/30 th that rate for the past century.

“These results suggest that the absence of protective measures could lead to US population movements of a magnitude similar to the twentieth century Great Migration of southern African-Americans”
As usual, they do not say what ‘protective measures’ should be undertaken by the government, Are they suggesting that the government build a 6 foot high sea wall around the whole of the country, for what, to most of us is a quite ridiculous scenario? First, they’re talking about what might happen in 100 years time .when none of us knows what the state of the earth will be at that time. Secondly, if it does happen it’s not going to happen overnight, so the change will be imperceptable. Thirdly the laws of evolution will ensure that if it does happen, as they predict, the population will look after themselves by building houses and property on higher ground to suit the situation at the time.(or perhaps they believe that the coastal population will not notice the rising sea and stay put ’till their lights go out)
Another quite pointless exercise from the ever-increasing and outrageously wasted work, time and cost perpetrated by our so called GW academics.

There willl be sea level rise but it is much smaller than the scare stories. Does that mean we do nothing? Like all the “effects’ of global warming that are excalimed we have been working on the mitigation of these things for hundreds of years already. The 1900s saw a 98% reduction of death from natural disasters. The first decade of 2000 has seen another 50% reduction of death from natural disasters (in 10 years 50% reduction) We are talking 1/100th the death of 1900 now in 2010. We will continue to improve every aspect of our defense against nature worldwide. A lot of the techniques learned and used in the US migrate to the rest of the world as it gets richer meaning that much of the additional gain over the next century would be huge even if all technological development ceased. It is likely by 2100 that ZERO yes ZERO people will die from any natural disaster at all without us spending any more than we do today or anybody spends. With ZERO change in any policy but just continuing with rolling out the improvements over the last century the number of deaths and actual damage will be constantly reduced by drastic amounts.
As the author points outs the adaptation by using new technology we haven’t even imagined could mean zero property damage zero lives lost zero effect from all the storms and droughts or whatever mother nature throws. This is not polyanna. This is clearly factual based on things everybody knows about today.
Yes, people will say but how do you handle rising seas? There are innumerable ways these are handled today from putting buildings on stilts or ilfting them which is a well known and economical practice to building walls and relocation. In the US most sea facing property is considered prime real estate owned by the richest companies and the richest individuals. I bristle at the notion we are supposed to spend vast amounts of money to save these people’s investments 100 years from now. I do not want one tax dollar going to save rich people’s houses or buildings 100 years from now. I fully expect rich people to spend whatever they need to protect, sell their property or do whatever they need to adapt to any sea level rise that happens whether 3 inches or 40 inches.
