Even with aggressive action on climate change, our economy will still be larger than today. All sectors will increase, including that great cash cow of oil and gas. In this "devastated" future, Canada will be richer and Wal-Mart will be bigger.
So, are we better off with action on climate change? Economically, we may be marginally worse off, but our well-being is rooted in more than economics. For starters, the growing trash heap in which we live may be a little smaller. And that may just make us all better off.
It really does seem opponents of climate change action are fighting for economic obesity, rather than settling for economic health.
