A statement from the University of Manitoba, where Barber has been teaching since 1993 and holding the Canadian Chair of Arctic System Science, said Barber died of complications from heart failure. “David was a visionary researcher with a passion for the Arctic, an entrepreneurial scholar and a generous mentor and friend,” said a statement from Barber’s colleagues at the Center for Earth Observation Science (CEOS). “He has touched the lives of countless people and he will miss them very much. Our thoughts and condolences are with his family and everyone who has known him.” Barber has been a major force in Arctic system science and research on climate change for over thirty years. Author of numerous academic studies and publications, Barber is known for his research on snow over sea ice and how changes in sea ice affect natural and human systems inside and outside the Arctic. Over the course of his academic career, Barber has won numerous accolades, including the Order of Canada Officer, a title awarded in 2016. Barber’s efforts have led to the establishment of a marine research center in northern Manitoba. “Canada should detect and mitigate transport-related leaks,” said a statement from the governor’s office. Barber was survived by his wife, three children, an adopted grandson and a grandson, according to the University of Manitoba. An event honoring Barber’s life will be held at the University of Manitoba on April 23, 2022.
