He headed an INTAS (International Association for the promotion of cooperation with scientists from the New Independent States of the former Soviet Union) project on geomagnetism and climate from 1997 to 2003.
[4] Mörner's self-published 2007 20-page booklet The Greatest Lie Ever Told,[5] refers to his belief that observational records of sea levels for the past 300 years that show variations - ups and downs, but no significant trend.
[15] Specifically, he mentioned a tree he had discovered growing close to the shoreline as evidence to support his claim that sea level had actually fallen rather than risen.
[17] “Early releases of the satellite Geophysical Data Records (GDRs) often contain errors in the raw measurements, the measurement corrections, and the orbit estimates that are later corrected through an on-going calibration/validation process defined by the T/P and Jason Science Working Team.” In March 2013, open-access scientific publisher Copernicus Publications began publishing Pattern Recognition in Physics, of which Mörner was the co-editor-in-chief, along with Sid-Ali Ouadfeul.
Due to both this study and what he called the "nepotistic" appointment of other scientists to the editorial board by Morner and Ouadfeul, Copernicus' managing director Martin Rasmussen terminated the journal in January 2014.
The renowned American skepticist James Randi offered him a reward of US$971,000 if Mörner could show that dowsing worked in a scientifically controlled experiment.
