There is a guaranteed solution to stop it from becoming apocalyptic which is comparatively easy and cheap, and we know it would work: just move away from fossil fuels and carbon intensive production ASAP. This requires political will we don't have, and fantasies like this just distract from what is necessary and the steps we must take.
These kind of pie-in-the-sky things takes money and attention from real solutions that work. They are false hopes that make people complacent and the problem seem less urgent, thinking that we'll tech our way out without fundamental changes to how we live on this planet.
