Prof. Bruno Tremblay, Department of Atmospheric & Oceanic Sciences, McGill University. The challenge of controlling, managing, or possibly reversing the impacts of human activities on our planet has an increasingly visible other dimension that has been given little attention, i.e., the actions of a stakeholder community whose interests lie with “business as usual” or that hopes to benefit from environmental change. These issues are playing out now in the Arctic, as it shifts from white, ice-bound, to a seasonally ice free, blue, and resource-accessible state. There are many environmental, socioeconomic and sociocultural arguments for restoring and sustaining a year-round, ice-covered white Arctic. At the same time, there are growing interests in the opening up of a blue Arctic Ocean. In this presentation, we will review recent changes in Arctic sea ice cover, possible causes for the rapid changes that are presently occurring in the Arctic and timescales (political, technological and physical) for the potential restoration of sea ice. This program was made possible with the support of Canal Savoir. http://www.mcgill.ca/science/events/mini
