I'm going to defer on the climate science question because I don't want to mislead you. You should call an Arctic scientist, perhaps Louis Fortier from ArcticNet, to talk to you about this.
On the issue of it being a tough sell, similar concerns were expressed back in the 1980s about the remedial measures needed to address acid rain. To his enormous credit, Mr. Mulroney got an agreement with the United States on acid rain that resulted in the installation of scrubbers for sulphur and nitrous dioxide on American power plants, which is why we still have fish in lakes around Ottawa.
These are new developments. They require new responses. Again, as I said, this isn't a partisan issue. I cite Mr. Mulroney because I admire what he was able to do on these issues, and I put him forward as a model. By working with allies like the United States, by embracing the opportunity to address new challenges, including through science and technology, we can be responsible stewards of Canada's Arctic.
