You're failing to put things in perspective. There are 500 trees on earth for each human being. That would mean they can absorb 12500 kg per year.
Also, tree are NOT the largest natural CO2 sink, oceans absorb more.
Overall, the biosphere absorbs about 50% of total human emissions (25% by land plants and 25% by oceans). I think that once we drop the CO2 emissions enough, the nature will quickly scrub it out of the air, we don't need to get negative ourselves, just drop close to zero and nature should balance itself pretty quick.
- Mizza 4y agoIt's a carbon _cycle_. We've spent a hundreds of years adding new carbon to that cycle as fast as our technology will allow, which is now very fast. It will remain in the cycle unless we sequester it back into the ground. Plants (for the most part) aren't CO2 limited, they're nitrogen limited. The climate also isn't something that will just snap happily back into place. We're in a local minima. If we climb up this hill, we won't like what we find in the next valley.
