About one quarter of the world’s permafrost regions are in Canada, underlying about half of our country. The North, especially the western Arctic, has had the most rapid climate warming, with annual temperatures at Inuvik, NWT, rising since the 1960s from -9.5 \u00b0C to above -6 \u00b0C. Adjustments in the precipitation regime are primarily to rainfall in early autumn. These indicators exceed projections made in 2000 for the magnitude of climate warming under the highest rate of greenhouse-gas emissions then thought likely. The consequences of such climate change for permafrost environments depend on the history of ice accumulation in the ground and\u00a0distribution of such ice with depth. Permafrost is no longer in thermal equilibrium with the climate, as it was 50 years ago. Instead, there are sites where the response to climate change is only in terms of temperature and others where ground properties are changing. In some cases, the adjustments to terrain integrity are gradual but in others catastrophic. The primary direct costs associated with climate change effects on permafrost accrue from deterioration of infrastructure. In Yukon, for instance, the proportion of the operation\u00a0and maintenance budget for transportation infrastructure associated with climate-related costs rose from 24% to 53% in 1994\u20132022.<\/p>\n\n\n\n

A graduate student of Carleton (MA 1983; PhD 1986), Chris has been a member of the Department of Geography since 1992. His field investigations on the permafrost environment in Yukon and\u00a0western Arctic Canada began in 1982, with the focus of the research on the relations between climate and\u00a0permafrost, particularly those driving the response of permafrost terrain to climate change. In 2018, he was awarded a D.Sc. by the University of Durham and, at home, the Polar Medal. In 2023 he received the Award for Scholarly Distinction of the Canadian Association of Geographers and in 2024 the Mentorship Medal of the Canadian Federation of Earth Sciences. He was President of the International Permafrost Association in 2020\u20132024.\u00a0<\/p>\n\n\n <\/div>\n\n
