For over 100 years the North European cities of Oslo, Stockholm and Helsinki have been steadily rising from the sea with no suggestion from observed evidence that local sea levels will not continue to drop by a few millimetres a year. That is until 2020, when the IPCC’s new AR6 Sea Level Projection Tool suddenly promoted substantial sea level rises all round. The discovery appears to baffle Ole Humlum, Emeritus Professor of Physical Geography at the University of Oslo. It seems that this tool was not produced to test the validity of a scientific idea. It was instead an attempt to “alarm the user”, he said.
