>During past fluctuations of CO2, the world had millions of years to adapt
We won't need to explicitly "adapt". The excess released carbon dioxide is going to make Sahara and Gobi greener, because it will be easier for the plants to grow with a higher concentration of CO2 in the air.
In other words, it's not going to stay in the atmosphere for a long time, it's going to become embodied in the trees and other plants.
Unless we diligently self-destruct by cutting literally all the trees living on the planet. (Possible, but unlikely.)
But even if we just keep doing what we are doing now at the same pace, it's going to be more or less enough. The excessive CO2 is _already_ making the planet greener.
(I guess it's a good idea to plant more trees anyway.)
