As I said earlier, one of the difficult things about climate change is that we don't have a long period of history from which to forecast events and the impact on the economy from events. It's really what we think of as shocks, and they can have an effect on growth.
If you looked at GDP in British Columbia, you saw the effects of the forest fires last summer very directly. In order to really think about the effects on the economy, you have to sort of forecast what we anticipate some of those shocks to be, how much more frequent they'll be, what the scale will be and those kinds of things.
