Nothing will change until developed rich countries are starting to hurt. And I don't think it's going to hurt enough in 10 or 20 years. The pain will come slowly, people won't see it. It's like going back to the middle age so slowly, that the population don't realize or feel it. And honestly, wars and trump are making climate concerns so difficult to think about.
They are already in pain but are blaming immigrants instead of trusting science.
Also true or false: an immigrant from a third world country will have a higher carbon footprint if they emigrate to a developed country.
Maybe they are part of the problem.
