‘Adjustments’ To Create Spurious Sea Level Rise Have Now Infected The PSMSL Tide Gauge Data

December 5, 2017

By Paul Homewood


NoTricks brings news of a new scientific study which uncovers more skullduggery, this time with tidal gauge data:



In a new paper published in Earth Systems and Environment this month, Australian scientists Dr. Albert Parker and Dr. Clifford Ollier uncover evidence that Permanent Service for Mean Sea Level (PSMSL) overseers appear to have been engaging in the “highly questionable” and “suspicious” practice of adjusting historical tide gauge data to show recent accelerated sea level rise where no such acceleration (or rise) exists.

Extensive evidence from “tide gauges, coastal morphology, stratigraphy, radiocarbon dating, archaeological remains, and historical documentation” all suggest that sea levels in the Indian Ocean have effectively been stable in recent decades.

The authors expose how PSMSL  data-adjusters make it appear that stable sea levels can be rendered to look like they are nonetheless rising at an accelerated pace.

The data-adjusters take misaligned and incomplete sea level data from tide gauges that show no sea level rise (or even a falling trend).  Then, they subjectively and arbitrarily cobble them together, or realign them.   In each case assessed, PSMSL data-adjusters lower the earlier misaligned rates and raise the more recent measurements.  By doing so, they concoct a new linearly-rising trend.

This adjustment of tide gauge data to yield a rising sea level trend where none exists is not occasional or episodic.  Instead, for every adjustment of raw data analyzed, “the adjustments are always in the direction to produce a large rise in sea level.”

The suspicious perpetuity of this pattern strongly suggests that there is an agenda driving these arbitrary and subjective realignments.

From all appearances, the data-adjusters at PSMSL are attempting to “correct” the sea level rise data that do not support the conceptualization of a rapidly-rising sea level trend in response to rising human CO2 emissions.

As Drs. Parker and Ollier conclude: “It is always highly questionable to shift data collected in the far past without any proven new supporting material.”

Not content with cooling the past, the climate mafia are now trying to reduce historical sea levels!

    The whole of “climate science” has been corrupted beyond belief by money and politics. Climate “scientists” invented fake news. The question is “how do we get corruption out of science”? Or is it even possible these days?

    Still, there’s no denying that the earth actually does go round the sun……………er – right?

    I’ve always said, the left will rewrite history and Britain ain’t in the sums. Science too, science SCIENCE!! we are lucky that they [the critical theorists] are a bit thick, well a lot thick really. Oh yes, that’s why of course these days they don’t teach the kids to add up, subtract and divine and think their own thoughts. It’s a parallel universe in Britain, thank cultural Marxism and a government who knows not of what it is about – since the day of Jan 1st 1973 when all their ‘thinking’ was done for them………..

    as we sail off the edge of the earth, don’t say u wuzn’t warming innit?

    When data is adjusted there is not unreasonable to expect full, detailed documentation of the rationale behind those adjustments – obvious – but seemingly that’s not the case in this matter.

    What should be of deeper concern is if access to the real, recorded raw data is obfuscated in any way (beyond the usual and inexcusable NERC bureaucratic nonsense) – can anybody save me the spadework of scoping that out?

    I think the responsibility for the adjustments should be better elaborated – as in PMSL is based at Proudman Laboratory in Liverpool and the present director is Dr. Lesley Rickards and it is essentially a department of NERC.

    I now treat all graphs as mere marketing devices. Not to be trusted. I even treat my own creations with suspicion and worry about any unsuspected garbage lurking in the input.

    Many thanks, we who don’t live next to the ocean have to depend on the internet for our information. 🙂

    These adjustments are worthy of Enron’s accountants.

    The AGW question is not whether the sea level is rising but whether SLR is driven by emissions
