Sea level lunacy slammed by Sir Tipene

from a National Business Review article of 1 September posted on Facebook:
“Sir Tipene rails against madness of Christchurch sea rise plan” by Chris Hutching

Resentment is growing among property owners in Christchurch and residents are organising themselves since the council announced it would tag 18,000 coastal properties with warnings of inundation from rising sea levels, severely depressing land values without good cause.

You might wonder why predicting rising sea levels might have been unexpected. After all, the whole world expects the sea to rise because we refuse to stop burning hydrocarbons.

Well, when you examine the actual evidence for rising seas, you find anomalies. The IPCC concluded in its latest report, AR5 (2013), that anthropogenic warming of the atmosphere (and thus the sea) would probably cause the sea to rise (by thermal expansion) about 450 mm by the year 2100. This is in the medium range of ‘scenarios’ offered by the IPCC, neither low nor high. The AR5 concluded the “likely” range for sea level rise by 2100 would be between 450 mm and 600 mm. So that is a reasonable amount to be expected, but the IPCC went a little further:

The basis for higher projections of global mean sea level rise in the 21st century has been considered and it has been concluded that there is currently insufficient evidence to evaluate the probability of specific levels above the assessed likely range. Many semi-empirical model projections of global mean sea level rise are higher than process-based model projections (up to about twice as large), but there is no consensus in the scientific community about their reliability and there is thus low confidence in their projections.

So whence comes this projection of one metre of sea-level rise? From the most extreme of the imagined scenarios of greenhouse gas emissions, called Representative Concentration Pathways (RCPs). The highest is called RCP8.5, which stands for a global level of radiative forcing of 8.5 W/m2 by 2100.

IPCC flunkeys usurp good guidance for Christchurch

The mean sea level rise under RCP8.5 is about 740 mm by 2100. But, you say, the Christchurch council has picked a figure 50% higher even than that! Why? Because that 1000 mm is the very highest guesswork that could possibly occur under RCP8.5.

None of these “calculations” are based on observations, but only on unverified computer models. Nobody knows, and cannot know until the time comes, whether these models are accurate, yet we are expected to believe them and sacrifice, in the case of Christchurch coastal properties, our personal fortunes on the expectation that the models are correct.

This is not science, this is scaremongering. On what basis has the council chosen the most extreme end of the most extreme emission scenario?

Lianne Dalziel, Mayor of Christchurch, claims the Christchurch earthquake gave us “50 years of climate change in a few minutes” to reinforce the one metre sea level narrative. The use of the earthquake tragedy as a climate change propaganda tool is despicable.

Here’s how the NBR described Sir Tipene O’Regan’s attack on the council’s reasoning.

Sir Tipene O’Regan is adding his voice to the chorus of protest against Christchurch City Council’s proposed restrictions on properties now deemed at risk of flooding from climate change.

Worst-case UN fantasy dooms foreshore properties

Sir Tipene lives at South Shore, one of the areas where council staff have tagged land titles, restricting existing rights to develop properties and laying them open to increased insurance and potential devaluation.

“What I find most offensive is their intellectual dishonesty. If they really believe in these projections, then they should be prohibiting all building in Christchurch and moving the whole place to West Melton (a small town to the west of Christchurch), or the Canterbury foothills.

“But they’re not. They’re building stuff all over the place that would be compromised if you accepted their theory. Why rebuild Christchurch at all if you believe this plan is valid?”

Abuse of power

Sir Tipene also says it is an abuse of power to speed up the passage of the district plan under the provisions of the Canterbury Earthquake Recovery Act, forbidding appeals except on points of law.

“This whole thing should be done on a national basis, not left to individual councils to decide.”
It was ironic that the earthquakes actually raised the level of the land where the O’Regan’s live by about one third of a metre (other areas at the neck of the South Shore spit fell).

“In that respect we now find ourselves on a little island surrounded by a sea of doom. That gives us another 130 years rather than the 100 years estimated by the council’s Tonkin & Taylor engineering report. All of the assumptions in the report fail to consider what might happen to the level of the land.”

Better a doormat than test the evidence?

“Pegasus Bay is built up from the sediment coming from the mountains down the Waimakariri, Ashley, Waiau, Hurunui and Clarence rivers,” said Sir Tipene. “It’s extraordinary they can talk about erosion without talking about that build-up. Wellington wouldn’t exist if it hadn’t been for the 1855 earthquake, which raised the place up.

“Nor have they considered mitigation, although they seem to accept it for the suburb of Sumner across from the South Shore spit where there is a man-made sea wall. It’s another indicator of the Christchurch class war.

“It’s a real indictment of the level of intelligence we’ve come to expect. These people are interviewing their keyboards. And you’d have to ask if the decision makers around the council table have even read these reports. [Cabinet minister Gerry] Brownlee and his minders have to say ‘slow down’ and look at this again.”

It’s hard not to agree.

    ‘Sweden: The land of the rising coastline’

    Reuters | 2 December 2012

    A Stone Age camp that used to be by the shore is now 125 miles from the Baltic Sea. Sheep graze on what was the seabed in the 15th century. And Sweden’s port of Lulea risks getting too shallow for ships. In contrast to worries from the Maldives to Manhattan of storm surges and higher ocean levels caused by climate change, the entire northern part of the Nordic region is rising and, as a result, the Baltic Sea is receding.

    The uplift of almost a centimetre a year, one of the highest rates in the world, is part of a geological rebound that has been taking place since the end of the Ice Age removed a vast ice sheet from regions around the Arctic Circle. “It’s a bit like a foam rubber mattress. It takes a while to return to normal after you get up,” said Martin Vermeer, a professor of geodesy at Aalto University in Finland. Finland gains 2.7 square miles a year as the land rises.

    In the Lulea region, just south of the Arctic Circle, mostly flat with pine forests and where the sea freezes in winter, tracts of land have emerged, leaving some Stone Age, Viking and medieval sites inland. That puts human settlements gradually out of harm’s way from sea flooding, unlike low-lying islands such as Tuvalu or Kiribati or cities from New York to Shanghai. Facebook is investing in a new data centre in Lulea on land that was once on the sea floor.

    But rising land also has a cost. Lulea is planning to deepen its port by 2020 to let in bigger ships and offset land rise; the price tag will be SEK1.6bn (£150m). Just to continue to accommodate existing ships, dredging the port would cost a quarter of that amount.

    Lulea’s old town, with a 15th-century church and bright red-painted wooden houses, built as an outpost of the then Swedish-Finnish kingdom to counter Russian influence near the Arctic Circle, was originally constructed on an island for safety. Now a village, it has been left high and dry, out of sight of the sea.

    In one spot, Sweden’s coastline has risen 300 metres since the Ice Age ended about 10,000 years ago.

    Interactive tool predicts future sea levels

    Sea levels are expected to rise half a metre in the next 50 years and coastal communities can now gaze into that future and get a glimpse of what it might look like.

    Waikato Regional Council launched its Coastal Inundation tool at the first Sustainable Waikato forum, held at the Don Rowlands Centre at Lake Karapiro on Wednesday

    […]

    Niwa coastal oceanographer Rob Bell, who collaborated with council on the project, told the forum sea levels were at their highest point in history and were expected to increase.

    “We have already burnt into the Earth’s climate system half a metre of sea level rise,” said Bell.

    Niwa and Ministry for the Environment advice said projected sea levels will continue to rise over the century to a metre above current levels.

    Bell said sea level rise is “certain to happen”

    The main points regarding the hearings panel were around interpretation of policy advice, and also the appropriate building codes to manage the perceived level of risk

    The main policy documents are NZCPS 2010 and CRPS (Canterbury Regional Policy Statement). Both these state a level of 0.5 m SLR should be planned for by 2100, and the effects of 0.8m assessed.

    Somehow, CCC, and every other council, have managed to morph this into a 1m SLR policy.
    New maps and clarification of building codes should help the panel come to a decision.

    Judge Hassan was very fair to all parties. I was most impressed by him.

    There is a one day conference on SLR on April 8th
    https://www.antarcticreport.com/articles/the-antarctic-report-sea-level-rise-conference

    From the blurb

    The sea has risen globally by 20cm on average over the last 100 years, but that increase has accelerated markedly in the last 20 years.

    Except the tide gauges don’t agree.

  14. Richard C (NZ) on 04/03/2016 at 11:50 am said:

    >”Both these state a level of 0.5 m SLR should be planned for by 2100″

    Even 0.5m is over twice the Lyttleton II historical trend. J Hassan is asking for 0, 0.5, and 1m. Historical falls between 0 and 0.5 so maybe they are considering that..

    Also can’t help noting the 100 yr timeframe keeps changing. IPCC projections begin 1990 i.e. those projections can and should be assessed continually (say every 5 yrs) because 25 years have already elapsed and 100 yrs falls on 2090. Then 100 yrs ends “by 2100” implying 100 yr projection starts from 2000. Now J Hassan is asking for 2115 from 2015 start which means 0.8 is to be “adjusted” to 1m.

    At this rate, I’m wondering when projections will start at 2100.

    And I see a big bone-of-contention is CCC waterways not being cleared and even planted. This was what happened in the Brisbane hinterland floods. Urban waterways were planted and had structures and walkway bridges built in them so the water was effectively dammed. Same thing on the farm I was bought up on. The waterway downstream was clogged so the flats of the farms immediately upstream flooded. The downstream farmer didn’t want to spend on clearance so the upstream farmers had to do the work at their own cost (the downstream guy allowed them to do this). Pollution in the floodwater had killed animals and the floods took pasture out of production for weeks.

  15. Andy on 04/03/2016 at 12:14 pm said:

    I agree the issue around starting points is a bit silly

    The MfE advise on planning for 0.5 m SLR by 2100 and then 10mm a year beyond that, so all the current policy is blindly adding 10mm a year for every year beyond 2100

    Then, the CCC project 1m SLR by 2115, which would require 14mm a year by 2115 according to my calculations, and then this magically transforms to a linear rate of 10mm a year after that.

    In the real world (which is obviously irrelevant here), Lyttelton II plods along at 1.7mm a year

    Wellington 2.45 mm/yr, Bluff/Southland Harbour 1.57 mm/yr (sparse data).

    “1.7mm a year” is the NZ per century average of multiple tide guages (I think). In any event, the multidecadal trends fluctuate markedly and each local tide guage differs from the NZ average.

    I don’t see how a blanket 100 yr advice can be issued across NZ given the above.

    “I don’t see how a blanket 100 yr advice can be issued across NZ given the above.”

    I explained to the panel that RCP 8.5 implies “catastrophic” climate change, temps over 5 degrees C above now, one metre SLR, based on some implausible socio-economic pathways (I didn’t go anywhere near the CO2 question)

    They got the message (not just from me though)

    Unless this kind of stuff gets challenged regularly, then one metre SLR just becomes a “fact”, embedded in the collective subconscious.

    >”Lyttelton II……. 2.36 mm/yr long-term from PSMSL data”

    From 1990 gives 0.295m rise by 2115
    From 2115 gives 0.236m rise by 2115

    From 1990 gives 0.059m rise at 2015 (plus or minus).

    This is the default long-term scenario. A departure from it requires proof of long-term departure occurring. That is, evidence beyond multidecadal fluctuation. NOAA’s 50 yr trends moving every 5 yrs shows this is all but impossible over less than about 50 – 100 years given 3.00 mm/yr 1940 – 1990 and 1.85 mm/yr 1950 – 2000 in Lyttelton II.

    ‘An answer to: Is the rise in sea levels accelerating?’

    by: Jan Kjetil Andersen, March 28, 2016

    […..IPCC AR5 case with updated data……]

    I have selected three set of series, which I call very long series, long series and medium long series.

    Very long series are 1900 through 2013; long series 1925 through 2014 and medium long are 1950 through 2014.

    In addition, all selected series have at least 80% complete monthly readings.

    Of the 281 stations in the Gloss network only 6 fulfils the criteria for very long series, 9 for long series and 22 for medium long series. The list of these stations is given in the end of the article.

    Two averages are made for each set of series; one simple average, and one global gridded average. The latter one was computed by dividing the globe in a 6×12 grid consisting of 72 cells measuring 30 degrees latitude times 30 degrees longitude. First, an average of all stations within each grid cell are computed. The global average is then an average of the all grid cells with a weighting of each grid cells according to its area. Because degrees longitude are shorter closer to the poles, the grid cells are also smaller. The relative length of one degree longitude, is cosinus of the degree latitude at the same spot. The weight of each grid cell is therefore the absolute value of cosinus of the degree latitude in the middle of the cell.

    The benefit with this method is that we get less bias toward the areas with most stations. The gridded average is therefore the most important of the two.

    The plots of absolute rise and 18-year trend are shown below.

    [see plots]
    Figure 7 a)-f). Absolute rise and 18-year trend for three different time intervals.

    b)18-year trend for very long series. Both start and end years for the 18-year period are shown. No discernible acceleration is evident from the moving average plot, but the linear trend line reveals a very small acceleration. However, all of this small acceleration is due to the small spikes in each end of the series.

    d)18-year trend for long series. We see that the largest rise occurred in the period starting around 1965. No discernible acceleration can be seen after the 1965 – 1973 period

    f)18-year trend for medium long series. We see an acceleration for the simple average, but any acceleration for the gridded set is more dubious. Except for a very short spike in the end, the rise in recent decades are no higher than 1960-ies. All the trend in the gridded series is due to the spike since 2011. To visualize this I have included a trend line of a series that stops in 2011 (green color).

    […]

    So what to make of all this?

    I have not made any regression analysis to show whether the small increase is statistically significant or not. I welcome anyone to do that. However, I think the graphs gives a quite clear message even without further analysis; if there is any acceleration, it is infinitesimal.

    Eugenie Sage: Would she discourage a first-home buyer from taking out a 30-year mortgage today on a home in a low-lying coastal area, given the risks facing such properties over the next 30 years?

    Hon PAULA BENNETT: It would depend on where it is, what mitigation happens over the next 30 years, and what adaptation local councils are taking responsibility for.

    Eugenie Sage: Does she believe that councils are giving homebuyers enough information on the effects that rising sea levels may have on future property values in areas like the south coast of Wellington, south Dunedin, and Napier’s low-lying suburbs?

    Hon PAULA BENNETT: Not consistently, no. I do not think they are giving enough information.

    Eugenie Sage: When rising sea levels cause worse flooding in coastal communities, leaving some homes uninsurable, will the Government be ready and willing to step in and compensate homeowners, as it did with homeowners who were affected in the red zone after the Canterbury earthquakes?

    Or incredibly bonkers.

    Applied to Wellington, that’s this graph except shown is 30cm in 35 years to 2050 as per Dr Jan Wright:

    30cm in 30 years is an even steeper, more bizarre, and totally unfeasible red line slope to 2045.

    These people are as mad as march hares

    As you say, 1.7mm a year in 30 years is about 5cm, and there is no obvious sign of acceleration.

    So we would require an average SLR that is 6 times the current rate, on average, over the next 30 years, for this “incredibly certain” outcome

    The latest saga is here

    “No compo for homes rebuilt in potential flood zone”

    http://www.radionz.co.nz/news/regional/303141/no-compo-for-homes-rebuilt-in-potential-flood-zone

    The council have managed to stuff up their mapping and let several houses be built at lower than the acceptable heights (i.e acceptable to the council), leaving property owners with devalued and potentially uninsurable properties

    Their flood heights are based on their climate projections.

    The council refuses to pay out compensation

    The latest MfE guidance indicates no new development within 1.9m of high tide.

    This is significantly worse than previous guidance.

    Oh, and the author is a previous Greenpeace employee.
