It is with great sadness that the Intergovernmental Panel on Climate Change (IPCC) has learned of the passing of James (Jim) Philip Bruce, a foundational figure in the establishment of the IPCC. In 1988, while serving as Deputy Secretary-General of the World Meteorological Organization (WMO), Bruce was instrumental in convening the first-ever meeting of the Panel at the Geneva International Conference Centre. Beyond his role in creating the Panel, Bruce remained actively engaged in the IPCC process, notably serving as Co-Chair of Working Group III for the IPCC Second Assessment Report, which examined the economic and social dimensions of climate change. He also served as a Review Editor for the Third and Fourth Assessment Reports and was a member of the official IPCC delegation that travelled to Oslo to receive the 2007 Nobel Peace Prize. Jim Bruce earned an undergraduate degree and an MA in Physics from the University of Toronto before beginning his career as a meteorologist. Throughout his distinguished career, he achieved numerous accomplishments at both the national and international levels. He was the first Director of the Canada Centre for Inland Waters in Burlington, Ontario, and served as Co-Chair of the International Joint Commission’s Great Lakes Research Advisory Board and Water Quality Board from 1972 to 1978. In 1985, he retired as Assistant Deputy Minister of the Atmospheric Environment Service at Environment Canada before continuing his public service at WMO for three years, first as Director of Technical Cooperation and later as Deputy Secretary-General. The IPCC extends its deepest condolences to his wife of 77 years, Ruth, to his family, friends and colleagues, and to the global scientific community.
