Ian Grote Stirling OC FRSC (September 26, 1941 – May 14, 2024)^[2]^[3] was a research scientist with Environment and Climate Change Canada and an adjunct professor in the University of Alberta Department of Biological Sciences.^[4]^[5] His research has focused mostly on Arctic and Antarctic zoology and ecology, and he was one of the world's top authorities on polar bears.^[6]

Stirling authored five non-technical books and more than 250 articles published in peer-reviewed science journals.^[4] Over the course of his career, and well into his retirement from Environment Canada in 2007, when he became a scientist emeritus, he wrote and spoke extensively about the danger posed to polar bears by global warming.^[7]

Early life and education

Ian Stirling was born to Andrew and Margaret Stirling on September 26, 1941 in Zambia, where his father worked as a mining engineer. They returned to Canada after the Second World War, settling in the mining town of Kimberley, British Columbia.^[2] He completed his B.Sc. at the University of British Columbia (UBC) in 1963, and his M.Sc. in zoology at UBC in 1965, where he met his spouse, Stella.^[2]

For his M.Sc. thesis, Stirling studied captive blue grouse under James F. Bendell.^[8] In 1968, Stirling received his doctorate from the University of Canterbury, New Zealand having done his field work on the Weddell seal from Scott Base in Antarctica, followed by post-doctoral research on South Australian fur seals at the University of Adelaide in Australia.^[9] His three children were born in New Zealand, Australia and Canada, respectively.^[2]

Career

From 1970 to 2007, Stirling was employed as a research scientist for the Canadian Wildlife Service.^[4] His research focussed on polar bear biology and ecology, with his most notable work being a long-term study of polar bears in western Hudson Bay near Churchill, Manitoba. He was among the first to draw attention to the potential impacts of climate change on polar bears.^[10] He was also an adjunct professor at the University of Alberta for more than 30 years, after settling in Edmonton in 1972.^[2] Stirling retired in 2007.

Stirling has served as a member of the Committee of Scientific Advisors of the Marine Mammal Commission, and he was the first Canadian to be elected president of the Society for Marine Mammalogy.^[11] He was a long-standing member of the IUCN Polar Bear Specialist Group and was also a scientific advisor to Polar Bears International.^[12]

Death

Stirling was diagnosed with lymphoma in 2019. The illness advanced to leukemia in 2023 and he died of effects of cancer in 2024, at age 82.^[13]
