Ratios matter little to the climate. Total volumes do. When you build your infrastructure from scratch, it makes sense not to go for XIX century technologies.
I agree. It would be much better if wealthy nations subsidized clean energy technology for developing countries so that they can leapfrog the fossil fuel stage.
On the other side of the argument, borders also don't matter to the climate, so everyone should be doing everything they can instead of finger-pointing, no?
Ratios matter a lot. If everyone behaved like Canadians we'd be fucked. If Canadians behaved like Chinese, we'd be less fucked. I was replying to someone who felt upset with China as a Canadian, and I explained his own country and its population behaves worse.
