  To expand on my comment, I think this is a sink or swim moment for humanity. I think we need a great leap in intelligence and technology to get out of this mess, either with AI or genetic engineering because we don't have centuries to come up with solutions and I don't think politics can solve it. It will take real technology to remove substantial amounts of CO2 from the environment, like small scale fusion, or self replicating solar along with efficient ways to remove CO2 from air. Nothing else will do I'm afraid.
