I have come across the work of Nils-Axel Morner who holds that IPCC reports that sea level is rising are inaccurate and alarmist. In his 2004 paper (http://www.sciencedirect.com/science/article/pii/S0921818103000973) he shows a graph of 'raw data' from the TOPEX/Poseidon satellite which shows that over the period from 1993 to 1999 there was no discernible change in global sea level. In IPCC AR4 Ch5 reference is made to a 2004 paper by Cazenave and Nerem which presents the same TOPEX/Poseidon data extended to 2003 but now shows a clear rising trend (http://www.eos.ubc.ca/~mjelline/453website/eosc453/E_prints/2003RG000139.pdf). In AR4 this series is further extended to 2006 and shows a continuing rising trend. It is very much based on this paper that the AR4 drew its conclusions about sea level rise.
Can someone explain to me why, at least for the first 6 years, these two presentations of the same data show such divergent trends? Morner is also reported as saying: 'In 2003 the satellite altimetry record was mysteriously tilted upwards to imply a sudden sea level rise rate of 2.3mm per year. When I criticised this dishonest adjustment at a global warming conference in Moscow, a British member of the IPCC delegation admitted in public the reason for this new calibration: ‘We had to do so, otherwise there would be no trend.’ (http://iceagenow.info/2011/12/satellite-sea-level-data-tilted-distort-figures-sea-level-expert/) Robert Chris The Open University [email protected] -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
