Do you have any references on the actual speed of reabsorption? I tried to find some, but didn't have much luck. I've heard numbers as high as 200 years to absorb all of it, but I don't know how "all" was defined for that metric. 90%, 99%, 99.99%? The actual rate of reabsorption is a pretty critical metric here. Even if it only takes 50 or 100 years to absorb half of it, that may not be fast enough as CO2 levels in the next 50 years are still pretty important considering potential feedback loops that could be triggered in that time frame.
