Polls counsel that O’Toole’s political judgment is right: Canadians are extra anxious about local weather change than Individuals.

They’ve already absorbed the lesson of this summer time’s wildfires:

The consequences of world warming are not confined to a couple weak areas. They’re seen from the Pacific Northwest to japanese Canada, from Siberia to southern Europe and South Asia.
