Duncan Wingham is Professor of Climate Physics at University College London, and was the first Director of the Centre for Polar Observation & Modelling. He is a member of the NERC Science and Technology Board and is Principal Scientist for the CryoSat Satellite Mission.[1]
In the 90s, Wingham was involved in a four-year satellite study of the Antarctic ice sheet. His conclusion then, and from later research, is that the Antarctic has contributed little to observed rising sea levels in the 20thC. Paradoxically Wingham stated It is possible that the consequences of global warming on sea level rise have been underestimated. He expanded Other sources of rise must be underestimated. In particular it is possible that the effect of global warming on thermal expansion [on the oceans] is larger than we thought.[2]
In a 2005 interview Wingham stated Antarctic is to some extent insulated from global warming because to its north are zonal flows in the atmosphere and ocean, unimpeded by other landmasses...I am not denying global warming[3]
