I really really wish that we are overdoing it.
The data just looks that bad, and we are one the worst path.
We emitted 5/6th of what's ok to stay below 1.5°C, and 2°C is not that much more, and we're not stopping. (500 Gt vs 600 Gt)
At the current emission rate (12 Gt/yr) we have 10 years left to stop completely. A few decades won't cut it.
Almost all scenarious of the IPCC now include negative emissions to be able to reach the targets.
The technology does not exist, would need to be implemented on a massive scale (eg plant all the available area minus agriculture and a selected few sanctuaries with trees and make biochar out of them) and the investment in eg artificial photosynthesis is not there, probably because there is little money in it. (The process is different from that for biofuels.)
We might not make it in time. Don't rely on this.
(The total available stored carbon seems to be on the order of 3000 Gt.)
