Noted Sea Level Expert Accuses IPCC of Falsifying Data

Claims IPCC estimates are bunk; Observational data shows no sea level rise trend

Note: Dr. Nils-Axel Mörner has been studying sea level change for 35 years. He is the former head of Stockholm University's department of Paleodeophysics and Geodynamics. Dr. Mörner is and an expert reviewer for the IPCC, leader of the Maldives Sea Level Project, and past president of the INQUA Commission on Sea Level Changes.

A noted expert in sea level change has accused UN's IPCC panel of falsifying and destroying data (PDF) to support the panel's official conclusion of a rising sea level trend. The accusations include surreptitious substitution of datasets, selective use of data, presenting computer model simulations as physical data, and even the destruction of physical markers which fail to demonstrate sea level rise.

The expert, Dr. Nils-Axel Mörner, also raps the IPCC for their selection of 22 authors of their most recent report on sea level rise (SLR), none of which were sea level specialists. According to Mörner, the authors were chosen to "arrive at a predetermined conclusion" of global warming-induced disaster.

Sea level changes can be detected by a number of methods. Rotational timing is a very precise method, and is based on the fact that a change in the earth's radius will cause minute differences in it's rate of rotation. A rise in sea level increases the radius slightly, and can therefore be detected by precisely timing when the sun rises and sets. This method can detect changes in sea level as small as one millimeter. Data collected in this manner has shown the ocean to have risen and fallen slightly several times since the early 1900s, without any definitive trend.

Satellite altimetry is another method. Mörner says that, in 2003, The IPCC's altimetry dataset, which had previously displayed no clear trend, suddenly changed, with past readings modified to show a strong uplift. Though corrections to datasets are supposed to be clearly announced and identified, this was done secretly, and not labeled. When Mörner inquired about the discrepancy, he was told the readings had been adjusted by a "correction factor".
Where did this factor come from? The least precise method of measuring sea level is tide gauge records. These are problematic as the land under the gauge may itself be rising or falling. Hong Kong maintains six tide gauges, five of which show no trend. The sixth, located on land where compaction is causing the ground to sink, was chosen by the IPCC as the correction factor for global altimetry data.... More   Comment in the Forums
