DESCRIPTION:Cutting Edge Lecture Series: Theodore G. Shepherd\, Dept of Phy
 sics\, University of Toronto. The phase-out of CFCs and other ozone-deplet
 ing substances as a result of the Montreal Protocol is a triumph of scienc
 e working together with public policy. Although the first indications of r
 ecovery from stratospheric ozone depletion are now becoming apparent\, bec
 ause 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. I
 n order to confirm the effectiveness of the Montreal Protocol it will be n
 ecessary 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 d
 epletion and recovery itself affects climate\, especially on regional scal
 es\, and this has to be properly attributed in order to understand and pre
 dict changes in climate. Thus\, the problems of ozone depletion/recovery a
 nd climate change are linked\, both scientifically and in terms of policy.
  This talk will explore some of these linkages. Organized by the Royal Soc
 iety of Canada and 9I制作厂免费 with the express purpose of fostering
  communication between scientists in different disciplines as well as betw
 een scientists and the public. Sponsored by the Royal Society of Canada\, 
 the lectures are made possible through the generous support of Heather Mun
 roe-Blum (9I制作厂免费 Principal)\, Richard Levin (Dean of Medicine)\, Martin Gr
 ant (Dean of Science)\, Anthony Masi (Provost) and Denis Th茅rien (Vice-Pri
 ncipal\, Research and International Relations). Lectures are followed by a
  wine & cheese reception.\nFree\, everyone welcome
