Swallowed Islands: Getting Sea Level Rise Out of Variability

Guest Essay by Kip Hansen

 

featured_imageDamien Cave, the NY Times Australia bureau chief, writes yet another heart-rending story with great personal touches about how the Solomon Islands are being “swallowed by the sea”.  His latest offering is titled: Solomon Islands Dispatch — His Pacific Island Was Swallowed by Rising Seas. So He Moved to a New One.

The story is about a seaweed “farmer” who grows a particular ” wiry breed that’s exported across Asia.”   The seaweed grows in the shallow water around his “island”.  Calling it an “island” is a bit of a stretch — it is really a sand spit or sand bar, “At mid-tide, it’s 24 steps across at its widest point, and 58 steps long.”   [ Note:  this is not a coral atoll — just a pile of sand, maybe over some bit of rock.] Of course, The Sea Weed King’s first sand spit got washed away by the currents, so he moved to a new one.  Here’s what it looks like:

seaweed_kings_island

We’ll have to guess what the elevation above Mean High Water is, the Times doesn’t tell us, but is certainly isn’t more than a foot or two.

Now, you can read the whole story in the NY Times (linked in the first paragraph) — but here’s the thing — the Times repeats this oft-echoed falsehood:

Scientists call it a global hot spot. The surrounding seas have risen about 7 to 10 millimeters per year since 1993, roughly three times today’s global average — and what scientists expect across much of the Pacific by the second half of this century.”

They get that impression from someone looking at graph like this:

A_rise_out_of_variability

That’s right — my golly — 225 millimeters in 25 years — that’s 9 mm/yr!

Oh my — I won’t say it — I won’t.  I will not call this F… News.

I will, however, supply a more pragmatically annotated graph of the NOAA-listed  Tide Gauge in the Solomons:

tide_gauge_SLR_Stat1861

Experienced readers will see right away (have already seen in the first graph) how a big rise has been made out of highly variable data.  The data is extremely  variable — 18 inches of variability, which is about the same as the normal daily tides in the Solomons.  In fact, over the last 25 years or so, Mean Sea Level at Honiara has soared and fallen over an 18 inch total range, ten times or so.  Even if we insist on using the apparently somewhat outlier date of 1993 (far left) we can only squeak out a 4 inch rise comparing to range for 2015-2016 (a 6 month peak in 2017) and 2018.

A reverse-bias view would be something like this:

tide_gauge_SLR_Stat1861_2

 

The truth however, is the bare raw data for Honiara-B:

raw_graph

When we have the raw data graph (this is monthly MSL) a trained observer can see what the real situation is.  We suspect that an equipment move or change made the break in 1997 sometime.

Drawing “trend” lines over times series graphs is itself a form of bias, constructed from the choice of start and end dates.  I have already demonstrated that the “alarming rise in sea level” in the Solomons is a construct of such choices and presents an entirely false image of the situation.  Likewise, selecting mid-1990s to early-2018 is equally biased, but in the opposite direction.

The graph immediately above is what we really know about sea level changes at Honiara-B — there has been a very wide range of variability over the last 25 years.  Mean Sea Level at Honiara-B is currently running low in the range, not high.

How one finds out about all this is to go to the PSMSL website and find the PSMSL page for Honiara-B station in the Solomon Islands.  There is a lot of information there, but the data authority for Honiara is actually the National Tidal Centre in Kent Town, South Australia.  The National Tidal Centre page for Honiara offers downloads of yearly data.

# # #

Of Note:  The New York Times article quote used above contains this:  sea level has “risen about 7 to 10 millimeters per year since 1993, roughly three times today’s global average — and what scientists expect across much of the Pacific by the second half of this century.”   This links to a very interesting 2015 paper titled: “Coastal vulnerability across the Pacific dominated by El Niño/Southern Oscillation” in NATURE Geoscience by Patrick L. Barnard et al.  It is a mystery to me why they used this as a reference as this paper does not make any predictions for mean sea level rise for the Pacific, none, at all.   It does, however, say this:

“Upper-end sea-level rise scenarios [IPPC projection scenarios] could displace up to 187 million people by the end of the twenty-first century1, with flood losses exceeding US$1 trillion per year for the world’s major coastal cities by 2050 (ref. 2). However, prior studies typically omit key oceanographic components of water level elevations during storms that drive severe beach erosion and flooding of coastal communities, and can be highly temporally and spatially variable. As the climate system evolves nonlinearly, so too will the spatial distribution of mean and extreme wind speed, wave height, period and direction, water level anomalies, and resulting coastal response, as is evident from trends observed over the past two decades.”

and

“We find that observed coastal erosion across the Pacific varies most closely with El Niño/Southern Oscillation, with a smaller influence from the Southern Annular Mode and the Pacific North American pattern. In the northern and southern Pacific Ocean, regional wave and water level anomalies are significantly correlated to a suite of climate indices, particularly during boreal winter; conditions in the northeast Pacific Ocean are often opposite to those in the western and southern Pacific.”

# # # # #

Author’s Note:

Journalists should do their job.  They should check the most pertinent facts for themselves — in this case:  Is sea level really rising 7-10 mm/yr in the Solomons?

Finding out that it hasn’t and isn’t makes a much more interesting story than “yet-another-alarmist-talking-point”.

Do note that while coral atolls are generally self-regenerating, sand spits/sand bars are not — they are at the mercy of the currents and waves.

Thanks for reading.

This story is idiot-bait. You measure sea rise during an El Nino in the Solomon Islands (which as a whole will be around for another 10M years) and claim panic? Did you try this year when the weather condition is La Nina and claim the land is rising? Or the seas receding?
Because that is what the measure shows.

In fact you have it backwards. The hot Nino years of early 2000s show lower sea levels in West Pacific Solomon Islands. The “super el Nino ” of 1998 is a notable trough in the data. The building El Nino from 2012-2016 also shows a drop.

This graph seems to be a fairly good proxy for ENSO cycles, if someone has the time to plot the two.

Warmer surface water accumulated in WPWP spreads eastwards during El Nino and causes a warm anomaly in tropical Pacific SST. This is reflected by a drop in MSL at sites like the Solomon Islands.

The Times article can easily be show to be fiction by plotting the data and showing linear regression instead of cherry picking two points and joining them together in MS Paint .

It should also be quite obvious that water levels at some point on the globe can not keep rising three times faster than the global average. It’s a pretty stupid proposition which even an uneducated person would question.

Also worth remembering is that coral bleaching occurs during strong El Nino, because of sea level fall, and the Indian Ocean is also impacted.

Hi Kip, I agree about all the caveats, I was just showing that however the authors arrived a 7-10 mm / y it was BS. Linear regression provides the best fit of a constant rate of rise for that data. and it is half to one third of the range cited.

That would be the most scientific way to rebut their claim. Maybe you would like to add that graph and the true rate of change as an update at the end of the article.

Solomon Islands are in a “hot spot” in the sense that it is some of the warmest SST on the planet. It is NOT a “hotspot” for sea level rise. It is totally average.

In fact if you start after the anomalous drop caused by the 1998 “super” El Nino, there is no statistically meaningful trend over the last 20 years. ( insignificantly negative. )

Kip, the rise is totally bogus science. See graph above, linear regression gives 3.4 mm/y with that data. That is totally in line with global averages. No sea water piling up ever higher in WPWP.

Unless of course they are Climate Correspondents for the BBC who fall over themselves to tell us about places with high “sea level rise”. I am aghast at the deliberate and disingenuous way in which the issue of relative sea level is dealt with by people (and their agents) who have snouts in the climate troff. Interesting how they ignore completely the most obviously and most sensitive place of all in Europe….The Netherlands…Strange that! The lack of scientific rigor in the prosecution of research around sea level indeed a large part of this trillion dollar a year scam is deliberate and Joe Public is just told “believe”. Isostasy and eustasy figure nowhere in the calibration of any sea level data I have been party to. The fact that media outlets like the BBC can brazenly promote alarmism with downright lies connecting problems for example in Miami or the Mekong Delta to climate change supposedly quoting “scientists” is an insult to all normal scientists working outside the smoke and mirrored world of climate “science” for whom professional integrity and ability dictates employability. Indeed, I find it more and more difficult to put the words climate and scientist together. When your livelihood depends on the Climate Merrygoround your integrity MUST be in question until proven otherwise. Climate “activist” is a better term and frees the rest of real science from this embarrassment!

Remember the battle for Guadalcanal 1942-43. For six months US Marines and Japanese troops fought over the control of Henderson Field on the north coast of the island. Whoever held Henderson Field ruled the skies over the Eastern Solomons because it was built on the only piece of land flat enough and big enough for an airfield in the whole Eastern Solomons.

tide-forecast shows that Honiara has tides of 0.8-1.0 meters and on top of that they expect swells of 0.8 meters for next week. And that is without any big storms passing by.
So who gives a frack about an adult actors length per century of rise. Another industry that is known for it’s exaggerations.

July 26, 2018 9:16 pm

Oddly enough, NOAA has data for that location going back much further:

Linear trend = 2.576 ±3.571 mm/yr
Acceleration = 0.284 ±0.635 mm/yr²

The midrange value for that linear trend is slightly higher than the global average, but certainly not worrisome. 2.576 mm/yr for 84 years would be 8.5 inches of sea-level rise by year 2100.

Notice how sea-level falls in the western equatorial Pacific during El Niño events. That’s because the east-to-west (“easterly”) trade winds weaken during El Ninos, causing the ocean water to slosh east. So at San Diego, Calif., the opposite happens: sea-level spikes up during El Niño, and drops during La Niña.

Worth noting that the R-Squared is 0.083 and the error is 1 mm/yr larger than the linear trend, so the actual trend could be -1 mm/ yr. My statistics prof. would have said a 0.083 R-Squared means the data sets are unrelated.

Nice response, Dave! I note the quote “The surrounding seas have risen about 7 to 10 millimeters per year since 1993,…”

As I do not recall any tide gauges present in the “surrounding seas” it can mean only that satellite altimeter numbers make up the numbers furnished in the claim. They do not have the resolution to validate or verify these and thus are not empirical data. The tide gauge is, and the result is stunningly clear!!!

“However, the conventional SAR interferometry only can achieve meter level height accuracy.

Dave,
Just looking at your graph I’d say a linear trend before 1998 and another after 1998, before and after the probable instrument change, would both be pretty close to zero and possibly even below the global average. The jump after 1998 is fairly obvious.

Reply to  Dave Burton
July 27, 2018 10:19 am

I agree with y’all that short-duration records like these are of dubious value for trend determination. You really can’t even say with certainly that sea-level is rising at all there, over the long term. That’s why I dislike the practice of many sea-level specialists, of using data from large numbers of short-duration measurement records, rather than a smaller number of high-quality, long-duration records, like these:

That said, I wouldn’t go quite so far as to say this Honiara data is completely useless.

For one thing, it could be cleaned up a bit by adjusting for the obvious ENSO influence, just as we routinely adjust for predictable seasonal variations (annual cycle).

There might also be a bit of PDO influence evident in that record. To my eye, there appears to be a slight inverse correlation with PDO. From mid-1970s to late 1990s sea-level tended to the low side, while PDO was positive. From mid-2000s to early-2010s sea-level tended to the high side, while PDO was negative. Here’s a PDO graph:

Kip, w/r/t/ reporting too many digits of precision, that’s my longstanding practice if-and-only-if a confidence interval or error margins are also explicitly reported. Discarding insignificant digits is really just a crude shorthand for implicit confidence interval reporting. Reporting a few extra digits (along with the confidence interval!), avoids adding additional errors from rounding artifacts, and explicitly reporting the CI avoids conveying an erroneous impression about the precision with which the quantity is known.

If you look at the middle of the end ranges you get a ‘trend’ from about 6900 to 7000 so about 100 mm over say 24 years at most.

I saw a similar ‘kiddy fiddling’ of data based on Port Jackson (Fort Denison in Sydney Harbour) data since the late 18th century. The data had a distinctive periodic variation which was the PDO signal. The data started on a PDO ‘trough’ and finished on a ‘crest’. Lo and behold!!! an uptrend. You would have got the same for data created by a pure sinusoid!

Quite apart from the cherry-picked ‘elevation’ over two decades cited by the NYT reporter, I was struck by how many times the average Solomon Island sea surface had either risen (or plunged) about that same full foot over the course of just a year or so. Gave me motion sickness just following it with my gaze; or perhaps the feeling was due to once again getting jerked around by some pretend “journalist” in the current death spiral of a once proud profession in the informative service of their fellow citizens?

Is sea level really rising 7-10 mm/yr in the Solomons?

Yes. Yes it is, because they say it is.

Scientists call it a global hot spot. The surrounding seas have risen about 7 to 10 millimeters per year since 1993, roughly three times today’s global average — and what scientists expect across much of the Pacific by the second half of this century.

Somehow, only “scientists” know how a “hot spot” can be global and only in the Pacific at the same time. I wonder what brand of dihydrogen monoxide they’ve been drinking?

However, prior studies typically omit key oceanographic components of water level elevations during storms that drive severe beach erosion and flooding of coastal communities, and can be highly temporally and spatially variable.

Natural erosion and accretion can be very large. link People insist in building near the shore and every year folks lose their valuable property to the sea. This has been going on for centuries. In spite of this the world’s great harbors continue to exist.

Perhaps you should remove the ”guess” of broken or moved equipment in 1997, anyhow there is no Evidence of broken equipment, but opposite exists, namely following study. According to this study there was a high negative (reverse) Anomaly ( -30 cm/s) of Western intense boundary currents (WBCs) during 1997 related to ENSO. At least it indicates Sea level change during the event – see e.g. picture 9b from http://www.legos.obs-mip.fr/members/gourdeau/my-filing-cabinet/altisolsea/altipapier.pdf?lang=fr

Kip — One thing to watch out for re the Solomon Islands is that the region is at the juncture of a number of crustal plates. See https://en.wikipedia.org/wiki/Solomon_Sea_Plate

Two consequences of that situation:

1. Data for Honiara are not necessarily indicative of what’s going on at other locations in the region. Those locations can, and I believe do, move up or down somewhat independent of Guadalcanal.

2. Because there are subduction zones in the area, there can be significant vertical land motions that have nothing to do with global sea level rise.

This has been the subject of a LOT of discussion and terrible journalism over the years — some of it so awful that even the Guardian backed away from it at times. Here’s a link to an article by David Middleton with lots of links. https://wattsupwiththat.com/2016/05/16/five-pacific-islands-vanish-from-sight-as-sea-levels-rise-part-deux-the-erosion-strikes-back/

Interestingly, when we sailed the Bahamas back in the early to mid 90’s the main/official charts available at the time were based on British surveys from the 1800’s. The depths over the banks and inside the Exumas were still fairly accurate. Of course some of the entry channels and bars had moved around a bit from the storms but the overall depths were not noticeably different from the charts. It wasn’t until Belize where you worried about inches and had to watch the tides very closely.

That night sailing on the banks can be fun but maybe a bit scary in spots. I missed a pole by about 4 or 5 feet that marked a sand bar behind the Exumas one night…. saw it just in time Had two charts showing it to the west so I plotted a clear course well east of it. Damned thing had moved right into the middle of what should have been a clear channel… still had a bunch of fun though.

Someone should create an alarmist global cooling parody site that uses real data; it’s only tweak would be to select the start/stop of the timelines. Let the global cooling narrative begin!

Now if you really wanted to talk about DRAMATIC Sea Level rise, just take the 1998 to 2000 period.
Around 400mm in 2 years, 2 metres per decade, 20 metres per century.
Yet the current sea level is lower than 2000 and looking at Dave Burton’s NOAA graph shows virtually no long term movement at all.
The NYT story typical CAGW Hype.

Many of the sea level gauges in the western pacific show rises over shorter periods. There is a record in the Pacific that goes back a bit further than ’93 with a rate less than a millimetre per year. https://eyesonbrowne.wordpress.com/2018/03/28/kiribati-its-still-there-and-its-beautiful/

A journalist is not going to fact-check something if it fits the narrative they want. They’re more likely to fact check until they get the narrative they’re looking for.

Don’t call someone looking to fit a narrative a journalist. They are merely propagandists or politicians. Many personalities on TV news are merely script readers.

If you think that is bad, check out this statement in the Florida Realtors Magazine article about flood insurance:
“vulnerable South Florida could face economic chaos, especially in the face of rising seas. The region faces one to two feet of sea rise by 2060, according to the Southeast Florida Regional Climate Compact”

WOW!

Who is the Southeast Florida Regional Climate Compact?

http://www.southeastfloridaclimatecompact.org/regional-climate-action-plan/

This is what they produce:

“Regional Climate Action Plan”
“The Regional Climate Action Plan (RCAP) is the Compact’s guiding tool for coordinated climate action in Southeast Florida to reduce greenhouse gas emissions and build climate resilience. The RCAP provides a set of recommendations, guidelines for implementation, and shared best practices for local entities to act in-line with the regional agenda.”

And this is their agenda, note the magic word “funding”

“The Compact calls on the counties to work cooperatively to:
• Develop annual legislative programs and jointly advocate for state and federal policies and funding.”

It’s not the Climate Regional Action Plan ?

Yes. If anybody needs a climate action plan, or whatever you wish to call it, it’s Southeast Florida. Less than 1 foot of slr will cause severe problems in the Miami area, on top of problems they already have. See Kip’s reference.

And this has less to do about climate change and more to with continuation of modest slr which has put southeast Florida at grave risk.

Kip, I really wish you would change some of those pictures you used in that post….they are all from rain and have nothing to do with high tides….and the dog picture is in Key Largo, neighborhood called Twin Lakes, that has standing water every time it rains, that’s not tides either

yes, I know…and people are using them all over the internet to show flooding from tides….every one of them are from 2 3 and 4 day rains….see the clouds in the background…Florida is sunny, unless it’s raining
Second picture down…the one with Sally’s real estate sign in it…woman in red pants…with dog…..that’s Key Largo, Twin Lakes, it’s what we call marl, clay, it’s doesn’t perk…so you get standing water every time it rains…

[excerpt]

Donald Trump’s policies are eminently sensible and beneficial for the USA and the World – he is reversing destructive Marxist nonsense that is harming the economy and putting excessive control over everyone’s life into the hands of unelected leftist bureaucrats.

My expertise is energy. Cheap, abundant reliable energy is the lifeblood of society – it IS that simple!

Most politicians are so ignorant about energy that they should not even opine on the subject, let alone set energy policy. Trump is reversing the many leftist energy debacles, and restoring reliability and economy to US energy.

The example that America will set for the World will ultimately cause other governments to return to energy sanity. If they fail to do so, they will be unable to compete with the USA.

Low sandpit islands come and go all the time. In fact, one big storm could make that island completely disappear in one day. That island’s conditions says nothing about sea level rise or global warming.

The sea level rise from the graph is over 100mm/yr from 1993 to 1996, so I guess that means the oceans are rising much slower then they were. I can only postulate the increased CO2 in the atmosphere some how slows sea level rise from this graph.

I think a really skilled journalist would have measured the sea level during low low tide, started his/her SUV up and left it running and then measured at a high high tide. This would be the most exciting proof of CAGW and sea level rise. It certainly meets all their quality standards.

That Times chart must have been presented as some kind of joke. The “trend line” is so obviously skewed that it makes the actual trend look flat. In fact, looking at the raw chart with no trend lines I conclude that the “trend” is, in fact, non-existent. Do whatever mathematical analysis you want on it to show some kind of “trend” and it’s either wrong or so completely overwhelmed by the noise of the variation as to be meaningless.

But they are. Modern journalists see their “job” as promoting leftist causes. That’s why they became journalists: to make a difference.

California is also in the business of creating sea level rise. Look at California Ocean Protection Council projections for San Francisco compared to tidal gauge records:

Thanks Kip for the link and the article your wrote. You emphasize that the models behave in a chaotic manner due to unforeseen and unpredictable interactions between the component equations. In contrast, the earth’s natural climate is amazingly stable, maintaining a very narrow range of fluctuations in parameters like temperature and precipitation. In a similar way, models project radical changes in sea level, while the actual observed rise since end of LIA are quite slow and steady.

No, it’s actually a form of lying.

These tear jerker sea level rise stories are so silly. Anyone who lives on coastal lowlands and has any understanding of either geology or archaeology knows that sea level rise has been continuing for the last roughly 12KYA to 15KYA since the retreat of the last glaciation began. Where did the Bering Land Bridge come from, anyway? Every school child knows that’s the now submerged lands from whence humans migrated from east Asia to North America.

Google ancient geological maps of the Florida peninsula, and one can easily see that Florida at one time was several hundred miles wider east to west in the shallow Gulf of Mexico than it is today. It is for that reason that archaeological artifacts found to date in Florida tend to be rather recent, just a few thousand years old … the prehistoric natives tended to cluster along the shoreline, and 10 to 15 KYA that shoreline was way out in what is now the Gulf.
