Ironic OECD countries actually REDUCED their emissions based on a peak in 2007 and continue to do so. Not reduced as a percentage of GDP or adjusted for population growth, but reduced in absolute levels. It's all China, but I guess it's cool to blame things on developed countries.
There are literally 100k deaths in Europe that can be prevented if they lifted restrictions on AC so that they can feel good about making a negligible effect on carbon emissions. So I think you have it opposite, how much pain do rich countries have to endure before they realize that their efforts are in vain.
And before you say "that's because the West outsources all the dirty production to China", even trade adjusted emissions are down considerably and continue to be down.
Please do some research if you're interested in this topic, it's not hard to do. Just follow the logical steps.
1. What causes global warming
2. Who produces most of these chemicals
3. Are there any global trends over the last 20 years in production of these chemicals
