Thank you. I'll do my best. It's a very good question.
As my colleagues have said, there's no getting away from the fact that over time we are going to have to reduce our emissions of greenhouse gases, perhaps by as much as 60% and maybe even more. That depends very much on our carbon-cycle models and lots of other things. Because of the inertia in the climate system, because of the inertia in our socio-economic systems, the fact is that certain impacts are going to happen anyway, and we can't ignore those.
Those impacts will differ depending on who you are, where you live, and what you do with living. There are certain regions--for example, in the Arctic--where, as Dr. Peltier was saying, climate change is exacerbated and where the impacts can already be seen. The people who live in the Arctic are very aware of climate change and what they've seen, and of the threat to their health and their livelihoods. In some such places it makes some sense that one needs to think about adaptation.
Other places, because they may be rich or because of other factors, are perhaps not so vulnerable. Africa, for example, is argued to be very vulnerable. I have the pleasure of being associated with the program run by the International Development Research Council, with funding from Canada and the U.K., that looks at adaptation in Africa, because it's understood that Africa is one of the most vulnerable places. I would argue that if they're vulnerable, then their security is our security, and that Canada has a vested interest in actually trying to help those vulnerable countries to cope with climate change, because if we don't, I think there will inevitably be repercussions for Canada.
Thank you.
