Cutting Edge Lecture Series: Theodore G. Shepherd, Dept of Physics, University of Toronto. The phase-out of CFCs and other ozone-depleting substances as a result of the Montreal Protocol is a triumph of science working together with public policy. Although the first indications of recovery from stratospheric ozone depletion are now becoming apparent, because of their long lifetime, the removal of CFCs from the atmosphere will take the best part of this century. Over this time scale, climate change from increasing greenhouse gases is expected to modify the ozone layer. In order to confirm the effectiveness of the Montreal Protocol it will be necessary to distinguish between changes in ozone due to decreases in CFCs and those due to climate change. At the same time, the process of ozone depletion and recovery itself affects climate, especially on regional scales, and this has to be properly attributed in order to understand and predict changes in climate. Thus, the problems of ozone depletion/recovery and climate change are linked, both scientifically and in terms of policy. This talk will explore some of these linkages. Organized by the Royal Society of Canada and 韩国裸舞 with the express purpose of fostering communication between scientists in different disciplines as well as between scientists and the public. Sponsored by the Royal Society of Canada, the lectures are made possible through the generous support of Heather Munroe-Blum (韩国裸舞 Principal), Richard Levin (Dean of Medicine), Martin Grant (Dean of Science), Anthony Masi (Provost) and Denis Th茅rien (Vice-Principal, Research and International Relations). Lectures are followed by a wine & cheese reception. Free, everyone welcome
