Professor Jonathan Gregory FRS
Jonathan Gregory is a climate scientist, employed since 2003 at the National Centre for Atmospheric Science in the University of Reading (where he is a professor in the Department of Meteorology), and since 1990 at the Met Office Hadley Centre (currently as a Science Fellow). He changed his area of research after his PhD in experimental particle physics because of scientific interest in and personal concern about climate change caused by human activities.
He studies large-scale multidecadal physical processes of change in the climate system, using three-dimensional global models and observational evidence. He has made significant contributions to refining the concept and the evaluation of climate sensitivity (the magnitude of warming caused by increases in greenhouse gases), and to the projection of future sea-level change from ocean warming, ocean circulation change, and loss of ice on land (glaciers and ice-sheets).
He was a lead author of the last three Assessment Reports of the Intergovernmental Panel on Climate Change. He is one of the leaders of the World Climate Research Programme's Grand Challenge on sea-level change.
