I think the bottom line is that the case for global warming is gathering with every passing year. I'm not sure what the tipping point is for a rational person, but based on polls it seems 4/5 Canadians have reached it. The question becomes are we willing to do anything about it, and it probably doesn't even require changing our lifestyle in a measurable way to make a huge impact on emissions. It just requires that all decisions are made with emissions as a consideration.
