The impacts of oil and gas activity on peoples in the Arctic using a multiple securities perspective (GAPS)

Dawn Bazely, Annette Dubreuil, Gabrielle Slowey, Gunhild Hoogensen & Julia Blythe Christensen Kereliuk
Background: Since the early 1970s oil and gas development has come to dominate the industrial sector in the Arctic. At the same time, the region is experiencing climate change with increasing intensity. The pace of resource development has accelerated significantly in recent years as the price of oil and gas has risen, motivating industry to travel further north to extract fossil fuels for global consumption. Increasing pressure from various governments¿Russian, Norwegian, Canadian and American¿requires the...

Climate change Impacts on Canadian Arctic Tundra ecosystems (CICAT): Interdisciplinary and multi-scale assessments

Greg Henry, Alain Cuerrier, Angela Bedard-Haughn, , Keith Egger, Michelle Garneau, Richard Farrell, Robert Grant &
At some CICAT research sites, we established experiments that simulate warming and changes in snow depth and measured the responses. Warming causes earlier flowering, greater growth and an increase in the cover of shrubs and grasses. We also examined the changes in vegetation across large areas using satellite data, and our results have shown a decrease in important winter range of the Bathurst caribou herd during the past twenty years due mainly to increases in...
