>a healthy, fully greened planet You're making a lot of very strong assumptions, notably * That a healthy planet is a "fully green" one * That a "fully green" planet is healthy to the organisms that currently live on that planet, particularly humans The Jurassic Era, for example, was much more "green". Humans wouldn't have fared very well in the Jurassic Era. |

We're shooting north of the Carboniferous (+3C) and headed towards the Cretaceous Hot Greenhouse period, where average temps were +5C to +8C over where they are now.
Probably not survivable for humanity as we know it now.
We're already seeing wet bulb temperatures over the survivable maximum in some parts of the world, imagine stacking another 3-5C on top of that. Large parts of equatorial land would be fatally warm to humanity, and the temperate band for growing crops would shift at least a thousand miles north.
