The July 5th issue of The Economist has two articles pertaining to Canada and climate change. There is one on the Dion carbon tax and another on the pine beetle infestation in our western forests. Both topics have come up here before, but remain pertinent and worthy of discussion.
The critical ongoing question in the first case is probably how effectively Dion will be able to build support for his plan. In the case of the pine beetles, it is probably the extent of the epidemic, as well as the volume of greenhouse gasses that will be emitted as a result. Despite considerable efforts to prevent it, the beetles have now become established in Alberta, having killed more than half the lodgepole pine in British Columbia. Natural Resources Canada estimates that the infestation so far will produce 990 megatonnes worth of emissions by 2020: equivalent to well over a year of total Canadian output. If they spread into the boreal forest, the ecological and climatic consequences could be massive.
