But is it too late, give how much CO2 we’ve already pumped into the atmosphere, and how much will be pumped there in the foreseeable future while we wait for solar to be more cost-effective than coal? So what then? Geoengineering schemes to cool the planet? Technology to remove carbon from the atmosphere?

what do really expect to happen?

denial, despair, desperate measures that fall short, blame, and finally adjustment to the radically changed planet after decades of economic chaos, death, and dislocation
