On that point of what we need to do not affecting normal people - I don't think that's accurate either.
We WILL need to live different lives in the developed countries. Our lifestyles (beyond carbon emissions) are not sustainable.
If everyone on earth lived as those in the US did, we'd need 4-9 earths. So long as higher quality of life looks like how we live, people around will strive to adopt that. China is by volume, now the largest emitter, but it's only 1/6 of the US in per capita emissions!
I find it hard to see a scenario where we've addressed climate change and ecological collapse, while we live the way we live today.
