‘Adjustments’ To Create Spurious Sea Level Rise
Have Now Infected The PSMSL Tide 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.”
Apparently not even tide gauge measurements can be spared from those who tendentiously fiddle with raw data to satisfy an agenda.
‘Multiple Lines Of Evidence’ Affirm Sea Levels Are Stable In The Indian Ocean
The tide gauge result of Aden is perfectly consistent not only with the tide gauge results for Karachi and Mumbai. It is also consistent with the multiple lines of evidence, tide gauges, coastal morphology, stratigraphy, radiocarbon dating, archaeological remains, and historical documentation, for a stable sea level of about zero mm/year experienced over the last 50 years in all the key sites of the Indian Ocean (Mörner 2007, 2010, 2014, 2015a, b, 2016a, b).
Contrary to the adjusted data from tide gauges and the unreliable satellite altimeter data, properly examined data from tide gauges and other sources such as coastal morphology, stratigraphy, radiocarbon dating, archaeological remains, and historical documentation indicate a lack of any alarming sea-level rise in recent decades for all the Indian Ocean.
The new alignment of the data 1878–1936 and 1937–1994 seems by far superior to the one proposed by PSMSL. The aligned metric data 1878–1994 show a trend of − 0.05 mm/year, i.e., nearly perfect stability.
Stable Sea Levels Are Transformed Into Positive Trends Via Arbitrary Adjustments To Past Data
What is proposed as a single record in databases such as the Permanent Service for Mean Sea Level (PSMSL) is often the composition of data collected by different instruments, sometimes in different locations or over different time windows, with significant gaps in between one measurement and the others. … While adjustments are certainly necessary to produce a tide gauge record that may be analysed to infer a trend of the local relative sea level, the way that the alignment is performed may introduce rising or decreasing trends even where the true sea level is oscillating without any trend. How can we perform a proper alignment of data when there are gaps of years and the tide gauge has been moved, destroyed, or replaced?
