UN IPCC author: Antarctica’s abrupt glacial melting ‘greatly overestimated’
Dr. Andrew Shepherd, an IPCC author who works at the Centre for Polar Observation and Modelling, said the UOB study used calculations that appeared to have overlooked shifts in snowfall, noting that the "new estimates of ice loss computed (from the thinning of the ice) are far too high, because the glaciers in this sector just haven't speeded up that much."
Dr. Shepherd, who expressed doubt about the results of the UOB study, was a contributing author of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, and he is currently investigating the stability of the Larsen B Ice Shelf in Antarctica.
