Long image but worth checking out (I beleive I originally saw it posted on here in cool picture thread) -

If you reduce Canada's contribution to 0, and compound the rest of the line at a rate of 2% less, it just doesn't matter.
I think that it is important to reduce environmental impacts, to continue to R&D better products and processes that are better for the environment - but I can also do math, and it is obvious to see that climate change is not going away (unless we nuke 50% of the world's population, but that seems a little heartless).
The solutions to the problems that climate change will bring will cost huge amounts of money and capital, whether it is upgrading electrical grids to support EVs or retrofitting old buildings etc. and our country will need a strong economy in order to make those investments.
There is a difference between kneecapping your economy to try to stop the temperature from increasing, and investing in your economy for when the world gets hot, and I think the smart decision is the latter.
