Most previous environmental issues were somehow, if sloppily, fixed over time. Humans are not as thick as you insinuate. Some of them, yes, but the awareness of climate issues is already fairly widespread in most developed countries and is slowly seeping into other parts of the world as well.
I firmly believe that we will be able to sequester carbon economically one day. I am not able to say when, of course. But there are a lot of ways to sequester carbon already, even though expensive ones, and I don't see why they should stay expensive forever. Humans are pretty good in applied chemistry and always come with ways to do things cheaper.
And carbon sequestration isn't something that would require consent of the entire world. Even five or six countries working together could pull it off.
