Climate change: what's the solution ?

Some scientists argue that we’ve already gone too far…They say that mitigation alone, or reducing CO2 emissions at their source, can no longer prevent climate change and all the danger that comes with it. They think that geo-engineering our climate (releasing aerosols into the atmosphere, carbon capture etc.) to counter the effects of greenhouse-gas induced warming is the way to go. But can we do this successfully? Do we understand the global climate system well enough to determine the feasibility and risks involved? The 2009 Lorne Trottier Public Science Symposium will welcome climate scientists and a historian of science to discuss the scientific and social ramifications of geo-engineering our climate and whether mitigation is still where we should focus our energy.

Fifth annual Lorne Trottier Public Science Symposium, Thursday, Nov. 19, 5 to 7 p.m., Stephen Leacock Building, Room 132. All are welcome, but seating is limited. For more information call 514-398-2852 or visit
