Sir Brian John Hoskins CBE FRS, (born 17 May 1945) is a British dynamical meteorologist and climatologist based at the Imperial College London and the University of Reading. A mathematician by training, his research has focused on understanding atmospheric motion from the scale of fronts to that of the Earth, using a range of theoretical and numerical models. He is perhaps best known for his work on the mathematical theory of extratropical cyclones and frontogenesis, particularly through the use of potential vorticity. He has also produced research across many areas of meteorology, including the Indian monsoon and global warming, recently contributing to the Stern review and the IPCC Fourth Assessment Report.
Hoskins gained a B.A. (1st Class Honors) and Ph.D. in mathematics from the University of Cambridge, UK, in 1966 and 1970, respectively. He was then Reader in atmospheric modelling (1976–1981) and professor of meteorology (1981–present) at the University of Reading. He was Head of the Department of Meteorology (1990–1996) at the University of Reading and President of the Royal Meteorological Society (1998–2000). He was a Royal Society council member (1999–present) and research professor (2001–present) and the first Director of the Grantham Institute for Climate Change at Imperial College London (2008–present).
Hoskins has spoken on behalf for the use of meteorology in government, industry and society. His group at the University of Reading has expanded to become one of the largest Meteorology departments in the world. He was instrumental in establishing the Grantham Institute for Climate Change at Imperial College London, an international centre for climate change research. He has been Council member for the Natural Environment Research Council that funds and supports most of the environmental research in the UK, and has held numerous roles for the Met Office, most recently as non-executive director and Chairman of the Scientific Advisory Board.
He has made contributions to the Intergovernmental Panel on Climate Change scientific assessments. He contributed to the Stern review of the economics of climate change and was also a member of the Royal Commission on Environmental Pollution which recommended that the UK should aim for a 60% reduction in emissions of carbon dioxide by 2050. He was appointed to the Government's Climate Change Committee, which has been influential in the Government's decision to commit to an 80 percent reduction in greenhouse gas emissions by 2050.
