Guest Post by Willis Eschenbach
Well, my heart fell when I saw the recent BBC article which proudly proclaimed that the people of Kivalina were slated to become “America’s first climate change refugees” …

My heart fell for three reasons. First, because once again we are being presented with natural, expected changes in a shifting, unstable barrier island that are falsely claimed to be the result of “climate change”. Folks, barrier islands are just a pile of sand, and they erode, change, and alter their shape with every change in the ocean that built them. As the residents of the barrier islands of the US East Coast regularly discover (although apparently to their infinitely renewed shock and never-lessening total surprise and outrage), when a storm wanders through their neighborhood, the ocean is more than happy to totally reshape any barrier island at any time. The ocean thinks nothing of cutting a barrier island in two, it’s an everyday occurrence around the planet. And the ocean particularly messes with a location like Kivalina, which as you can see from the article is right at the main channel … where all of the water goes through with every tide, where runoff from a huge storm has to force its way out to the ocean, and where as a result the erosive forces are both the strongest and the most unpredictable.
Second, I was bummed that they’d built such a joke of a seawall, because as the photo clearly shows and the article mentions, the seawall there is having unexpected effects which are not all beneficial. As is common with such amateur attempts to tame the sea, it’s building up sand at one end and being eaten away and undermined at the other. No surprise there, except that this was the Army Corps of Engineers and it was built in 2008 … as I discuss below, they are way, way behind the times if that’s their idea of how to protect Kivalina.
The third reason I was saddened was that I immediately suspected the fine hand of some melanin-deficient historical BIA (Bureau of Indian Affairs) official in the original location of the village. The BIA has been the cause of huge grief for just about all of the people under its jurisdiction, so why not Kivalina? Plus, I doubted greatly that any group of nomadic northern hunters would choose to live right there, they’re generally much smarter than that.
When you look at the location of Kivalina on Google Earth, you have to say, what on earth were the BIA thinking? Never mind, they weren’t.
Figure 2. Overview of the entire island on which Kivalina is located, in the winter, with ice on the ocean. Note the sediment being discharged out the channel by Kivalina, and the areas of reduced ice outside both channels through the barrier islands.
In my previous post on this subject, aptly yclept the “Sixth First Climate Refugees“, it was pointed out that the Fifth First Climate Refugees in the Alaskan village of Shishmaref was located on a barrier island because they’d been moved to that spot by the US government. Years ago, there was a big push to stop the traditional residents from being nomads. Nomads drive governments nuts, you can’t control them. So the government very foolishly insisted the people settle in a terrible location, the barrier island where the town of Shishmaref is now located. Now, nomadic traditional people are far from stupid. You can assume that they were all too familiar with the fragility and changeability of barrier islands, because they only put temporary hunting camps on such islands, and wisely lived on the mainland behind the protection that such barrier islands until they were forced offshore. And the same forced resettlement was the story for the Sixth First Climate Refugees, those in Newtok, Alaska.
So when I saw the picture above, my first thought was, “BIA strikes again”. And sadly, my guess was right. The NANA, the Alaska Native Corporation of the northern peoples, tells the story of Kivalina on their web site:
HISTORY
For more than 1,500 years, the barrier reef where Kivalina is located has been a stopping-off place for seasonal travelers between the Arctic coastal areas and the Kotzebue Sound region. In 2009 human remains and artifacts were discovered near Kivalina representing the Ipiutak, a non-whaling Eskimo culture that was present in northwestern Alaska from the 2nd to 6th centuries A.D. The Ipiutak people inhabited the coastal region only in the spring and summer months, moving inland for the rest of the year.
According to elder knowledge, the original permanent settlement known as Kivalina was located on the coast of the mainland, a few miles north of Kivalliik Channel. The people of Kivalina, like the Ipiutak before them, utilized the barrier reef only as seasonal hunting grounds, making camp there in warm-weather months.The first recorded history of Kivalina occurred in 1847 when a Russian naval officer mistook a seasonal hunting camp at the north end of Kivalina Lagoon—a few miles from the location of modern-day Kivalina—as a permanent settlement, the name of which he logged as “Kivualinagmut.”
From 1896 to 1902, United States federal programs transported reindeer to the Kivalina area and funded the training of some residents as reindeer herders.
Kivalina was relocated to its current location in 1905 when the Bureau of Indian Affairs repeated the error of the Russian naval officer by mistaking a seasonal camp on the barrier reef for a year-round village. The BIA in short order built a school on the southern tip of the island and declared that any inhabitants of the barrier reef and surrounding region who did not enroll their children would be imprisoned. This order compelled the people of the original Kivalina as well as communities inland and north and south along the coast to migrate to the Kivalina created by the BIA.
Like I figured, the locals were far too smart to build permanent villages on a barrier island. They “utilized the barrier reef only as seasonal hunting grounds“. So the village is in such a dangerous, shifting location because white guys with guns threatened to throw anyone who didn’t move there in jail … charming.
Now, in response to the predictable erosion and change in the barrier island, the inhabitants of Kivalina sued ExxonMobil, claiming that CO2 was the cause of their problems … and wisely the Supreme Court threw it out.
The fact remains, however, that just as with Shishmaref and Newtok, the cause of the problems are human actions, although they have nothing to do with CO2. All three villages are in ridiculously unstable, shifting, dangerous locations for the same reason—they were rounded up by the BIA and forced to settle there.
So if I came from one of those villages, I’d want to bring suit as well … but I’d want to bring suit against the Bureau of Indian Affairs. Of course, I assume that in the usual Catch-22 fashion, you can’t do that, because the Feds are immune to most suits … grrr. I can see why the Kivalina folks are upset. I’m just afraid that they don’t have a lot of choices, and as a result they sued the wrong folks.
There is one possibility, however. Modern coastal engineering has progressed since the “just build a vertical wall” style of attempted protection represented in the picture above. The modern practice is to use cement-filled tubes of geotextile fabric that run perpendicular to the beach along the bottom of the ocean. These don’t attempt to stop the ocean, like the vertical seawall pictured above. Here’s the challenge.
Anyone wanting to change the shape of a barrier island first needs to realize that the lovely sand beach is not a solid object. It is a river of sand. Sand is constantly being picked up and moved by each and every wave, either up or down the beach. Now, if you put in a vertical seawall like the one shown in the picture, when the waves hit the seawall their energy is not dispersed. Instead, the energy is reflected down the beach. You can see the outcome in Figure 1.
First, note that in the more distant section of the island just beyond the far end of the seawall, the beach is much wider than after the start of the seawall. For the reason, look at the direction that the waves are striking. The problem is that instead of the wave energy being absorbed by the beach, it is being reflected to run parallel the seawall as a long-shore current. You can see how over time this long-shore current has scoured away the sand from the far end of the seawall, and it has deposited it at the near end.
And eventually, the seawall will be undercut entirely, because a vertical seawall also directs some of the wave energy straight downwards at the base of the wall. This scours the sand out directly under the seawall itself, and will eventually lead to its destruction and collapse. The people up in Shishmaref the Fourth First Climate Refugees, have exactly the same problem. There, a poorly designed seawall has shifted the wave energy to where it’s now eating away the town itself. Seawalls just move the wave energy parallel to the coast.
With the modern practice, however, no such vertical seawall is built. Here’s a picture of such an installation, just after construction:
Figure 3. Three concrete-filled tubes of geotextile fabric, two directly on the sand, and a third one on top of those two.
Note that instead of going along the shoreline, the concrete-filled tubes go perpendicular to the beach, straight offshore into deeper water. Now, remember that a beach is essentially a river of sand. Here’s the important fact—the amount of sand that can be picked up by the water depends entirely on the speed of the water. Fast-moving water can carry more sand than slow-moving water.
So as a corollary of that, if you can slow down the water that is moving the river of sand along parallel to the shore, it will drop its load of sand, and your beach will fill in and stabilize further out into the ocean. And that’s what the tubes full of concrete do. They don’t try to stop the water. They just slow it down a bit, as though the water stubs its toe whenever it goes over one of these tubes. When it slows, it drops its sand, filling in the area in between parallel tubes. A year or so after the picture above was taken, the concrete-filled tubes you see were totally buried in the sand, and the beach extended out well beyond the point of land. Counter-intuitive in a way, because there’s no seawall parallel to the coast at all … but it works like a champ, because it works with nature, not against it like a vertical seawall tries to do. Here’s a before-and-after picture of a larger project:
Figure 4. The waves were undercutting the bluffs, threatening the highway running along the top of the cliff. The system shown in Figure 3 was used all along the coastline. You can see parts of a couple of the concrete-filled tubes perpendicular to the land near the foot of the bluff at the lower right in the second picture.
So while the existing seawall is failing, that doesn’t mean that the folks in Kivalina are out of options. Here’s the link to a main company doing this type of installation, Holmberg Technologies. The pictures above are from their website. (I have no connection with them.) If I lived in Kivalina, I’d get all my ducks in a row tomorrow, and I’d have Holmberg’s on the phone tomorrow. I’d pitch it as Holmberg’s chance to a) get some great publicity, and b) to help to right a historical wrong. The Native Corporation might even be such that Holmberg could get a tax write-off for any contributions, I’d investigate that first. Then I’d call Holmbergs, and offer that the village would provide all the labor, and pay for the concrete, if Holmberg would do the coastal engineering and provide the special geotextile fabric tubes and oversee the project. I’d offer to put their name up all over the project, and mention them prominently in all of the publicity. Can’t hurt to ask … and if they say yes, then I’d hit up the nearest concrete company to provide the concrete as a donation for the same reason. Hey, why not? Could happen. You often don’t get what you ask for, I know that … but it’s rare to get something you don’t ask for, so it’s sure worth a few phone calls. Even if Holmberg says no, I’d get an estimate from them and a plan, asking them for their best possible rates for the reasons stated above, publicity and righting a wrong. Then I’d go out and raise the money, somewhere, somehow, to hire them to do it. See if Crowley Marine or another tug company might contribute towards barging the materials there. Looking at the beach in Figure 4, you can see that by Holmberg’s standards Kivalina would be a fairly small project … just in the middle of nowhere.
Now, the best option is still for the village to move, because no matter what they do to their island, it’s still just a bog-standard barrier island, which means a shifting pile of sand in an incredibly powerful ocean. There are no guarantees in that situation, even with the best coastal engineering advice on the planet.
For example, note in Figure 2 that at the ends of the island where Kivalina is located, both of the channels are located directly across from the main river outlet on the mainland. This is a common situation with barrier islands. Gaps in the islands across from the main rivers allow floodwaters running of the land to go straight out to sea.
Now, look at all of the abandoned channels in the mainland … and consider that in the past those have been the main channel, and could be again. Not “if” but when that happens, it will likely cut through or greatly change Kivalina’s island. So staying is problematic in the long term.
But given the cost of moving the village all at once, If I Ran The Zoo I think what I’d do is first hustle up the donations and the $ to install the new concrete-filled tubes to build up the protective beach on the seaside of Kivalina. That will buy some time. Then I’d pick a good spot for the village on the mainland, maybe even the spot of the ancestral village if that’s a possibility. I’d do all of the necessary local ceremonies to bless the choice, get everyone involved so it’s a true community grassroots decision. I’d divide it up into lots based on what the locals say is fair, plenty of different ways to do that, and offer them to the villagers to move to. There’s got to be better land owned by the tribe or controlled by the BIA somewhere in the area. And that way, over the next decades the population could slowly shift to their new homes, without an immediate costs of millions of dollars.
But all in all, there’s no real good answer. Tragically, it’s more of the usual kind of pain and suffering that trails the actions of the BIA like a bad smell. They have been highly corrupt and totally inefficient since their inception. They’ve screwed their “wards” out of millions and millions of dollars. They’ve taken children from their parents and forced them to stop speaking their native languages. The list of their misdeeds is very long, broken treaties and false promises and government obfuscation and embezzlement at each new page in their sordid history. Every Indian or Eskimo I’ve ever known has said that the Bureau of Indian Affairs is nothing but a nest of crooks and thieves, and in my reading I’ve never found anything to contradict that in the slightest …
Anyhow, that’s the story of the Seventh First Climate Refugees. Turns out that they aren’t climate refugees at all, they are BIA refugees. Just another in a long parade of Alaskan and other tribes who have been shafted by the BIA, forcibly settled in a totally unsuitable location, and as a result left with few good options.
Best regards to all, and as a melanin-deficient person myself, other than my poor ideas about fixing the situation, all I have to offer to the good people of Kivalina are my apologies for the historical actions of people who looked like me, and my sincere wishes for success.

PS—BBC, your climate reporting is pathetic. Doesn’t anyone there think to check up on some dewy-eyed reporter gushing on about the tragic fate of the latest batch of pseudo-refugees? Missing the facts in this story would have been understandable a decade ago, but in 2013, you guys are a running joke. Something on the order of …
How many BBC climate editors does it take to change a light bulb?
No one knows, it appears their lights went out years ago and haven’t been replaced since …

“Now, in response to the predictable erosion and change in the barrier island, the inhabitants of Kivalina sued ExxonMobil, claiming that CO2 was the cause of their problems …”
These people have come along way. They’ve forgotten what their ancestors knew and replaced this knowledge with the melanin-deficient kind.
Willis great article But as usual what is really truly amazing this technique has been used by the Dutch and the Brits themselves for hundreds of years, just go for a walk a long the coast of Holland and the Eastern coast of Brittain and every 100 -150 yards there is a rock pier (imported from French and Swiss Quarries for Holland). Another technique that seems to work along similar lines are not straight up and down seawalls but walls shaped like a stair case, I build one of those ten years ago and it worked to perfection, local laws prevented me from going into the water beyond low water lines.
……beach defences often known as groynes. (interestingly spellcheck’s never heard of them)
http://www.bing.com/images/search?q=groynes&qpvt=groynes&FORM=IGRE
BTW that are now 20 feet further out LOL.
I looked on the BBC page for the words ‘barrier island’ and ‘barrier’ but came up with zero. They did mention that
In some ways you have to excuse Stephen Sackur, the author, as he is not an environmental journalist and probably doesn’t understand what is going on here. He has said:
Maybe he should have carried out “exhaustive research” before literally flying into new territory.
groynes, probably derived from “groans” (the sounds heard all a long the beaches when they were being built.
The Tube concept is not new. Indeed, you will find Jetties all up and down the coasts here. They are merely piles of rocks perpendicular to the beach. And for anyone that has been to “a beach” over an extended period of time, the slowing of the water and depositing of sand is very evident.
But the US Government built the wall in 2008? What lobotomized BIA imbecile forced that move? I am in my 50s so I have seen jetties for over 50 years now.
It has also invested heavily in oil companies and tobacco such as BP, Shell, Occidental, Philip Morris, Imperial Tobacco etc. Anyone who thinks the BBC cares a jot about global warming is living in fairy wonderland.

>>>>>>>>>>>>>>
You forgot to add the US government did this because White Settlers wanted the good land the natives were using. The US government has a long history of moving natives to useless good-for-nothing land and then when the natives can’t make a living there the whites would call them lazy…
“If I lived in Kivalina, I’d get all my ducks in a row tomorrow, and I’d have Holmberg’s on the phone tomorrow. I’d pitch it as Holmberg’s….”
Oh but it is much easier to become the helpless victim, hire some lawyers and let them force someone else to fix the problem. Unfortunately this is how society has evolved as people are constantly brainwashed into believing only government can help while all along, as Willis has pointed out, it is government that is usually the cause of the problem in the first place. Speaking of the Army Corps of Engineers, that agency has done so much damage to so many areas it is a wonder that they are still allowed to be called “engineers”.

Are the army engineers really that stupid? Or did someone decide to build an ineffectual seawall? Scary thought.
Perpendicular breakwaters have been in use in Australia since before I was born.

The were also in use in the USA. I can remember walking (or trying to scramble) on them as a child.

I know one thing for certain. There looks like a beautiful left hand tube wave in that first photo. But if you want to surf it I suggest a very thick wetsuit.

Right. How are they expected to pay property taxes if they’re always moving around….
Groynes were built on the British coast by the Roman Army almost 2000 years ago ,BBC learns very little from history.
Are they the last of the survivors of the 50 million refugees in 2010?
Get a Dutch polder engineer in there and Bob’s your uncle. I share what seems to be general outrage at the BBC. This story is ludicrous. Now the BOOB is in the US and has even managed to get its fingers in the Public Broadcasting System pie, which is subsidized by the American taxpayer.
“but it’s rare to get something you don’t ask for”
Tax Hikes….
The Army Corp of Engineers has a predilection for creating environmental problems, but then they are only following their masters wishes for the most part such as their work in the Everglades.
A number of people have mentioned jetties or breakwaters. Those are not the same as Holmbergs. The jetties block the flow of sand rather than slowing things down. While the upstream part of the beach builds up, the downstream part winds up being starved for sand.
@BarryW – I was one of the neophytes that mentioned jetties. Thanks for the explanation of the difference. You are indeed correct. The sand builds up on the wave side of the jetty, and is lost on the other side.
“PS—BBC, your climate reporting is pathetic.”
And it only costs me £145 a year for the privilege…
“I know one thing for certain. There looks like a beautiful left hand tube wave in that first photo. But if you want to surf it I suggest a very thick wetsuit.”
That wave is only a couple feet high so maybe your feet will get tubed! That triangular point means there is another common wave direction, which means at times there may be two entirely different breaks going on at the same time, at essentially right angle to each other. This can be fun as at the intersection a surfer can switch from one wave to another going at right angle!
Is that a fishtrap (round depression in the sand) located on the protruding section of the island at the lower left (SW ?).

Please Willis, permit me to rephrase that to make a point:
“So the world is in such a dangerous, shifting situation because officials with guns threaten to throw anyone who doesn’t comply in jail … charming
============
I agree with Jan. Official corruption is color blind. It is much easier to steal armed with a gun and a badge than with a gun alone. It is even easier when you do so in the name of “helping”.
Great post Willis. Perpendicular breakwaters, typically made from rocks, are found in many areas of the world and they work by building up sand along the shore. They mimic the way nature creates sandy beaches at the heads of bays.
The other approach, building sea-walls along the beach has been shown time and against to be a failure. It leads to erosion of the beach, and ultimately dooms the sea-wall to failure by undermining.
Before the invention of explosives, the standard method to bring down castle walls was to tunnel under them. The weight of the walls would then cause them to collapse into the tunnels. Nature uses this same approach to bring down sea-walls.
In his usual cut-to-the-heart-of-the-problem, Willis’s characterization of the barrier bar at Kivalina captures the essence of the problem in a single sentence: “barrier islands are just a pile of sand, and they erode, change, and alter their shape with every change in the ocean that built them.” This is in rather sharp contrast to the story by Stephen Sackur of BBC who says “within a decade Kivalina is likely to be under water” as a result of CO2-induced climate change. According to Wikipedia, “As of 2013, it is predicted that the island will be inundated by 2025.”
What’s wrong with the BBC and Wikipedia contentions? Well, to start with, you’d think that both of these sources of misinformation would have bothered to take the time to check Alaskan tide gauge records to see what sea level in Alaska is doing. NOAA lists 15 tide-gauge records and all show a strong negative trend since the mid-1960s. None show any sea level rise in Alaska in the past 50 years! In general, Alaska is not drowning, it’s emerging from the sea! The drop in Alaskan sea level varies from about 1 to 10 mm/yr from place to place, so in 10 years we could expect to see as much as 100 mm (~5 inches) of sea level drop in Kivalina..
Secondly, they predict inundation within a decade. Most of Kivalina is about 10-13 feet above sea level. To drown Kivalina in a decade would require a sea level rise of about one foot per year! Compare that to the actual tide gauge records that suggest as much as 5 inches of sea level lowering. The absurdity of the BBC contention, especially in view of Alaska’s negative sea level change over the past 50 years, is self evident.
Thirdly, Kivalina is situated on a barrier bar at the distal mouth of Kivalina delta. Kivalina is located on a barrier bar built by sediment pushed laterally along the shoreline by wave action. Or as Willis so aptly puts it, a ‘river of sand’ moving along the coast. This is a typical, dynamic geologic situation–the barrier bar is not going away, it will continue to grow as more and more sediment is contributed to the coast by the Kivalina delta.
Fourthly, the cost of relocating Kivalina is estimated to be $400 million (guess who would get to pay for that). Money could be put to far better use in helping people.
A minor correction about the dynamics of man-made groins (barriers at right angles to the beach). Deposition occurs behind the up-wave portion of the barrier because it blocks down-coast transport of sand, not because it slows down the water. To see how this works, refer to p.558-461 in “Surface processes and landforms” by Prentice Hall.
What we can learn from this is that poorly thought out contentions by non-scientists totally destroys their credibility.
Brilliant again, Willis. Nice work uncovering the roll of the BIA and an excellent example of unintended consequences.
