How would we get to negative emission levels?
I'm sure natural processes have some capacity to absorb additional carbon, but I feel like we're way past that point. Given how much we've already increased CO2, it will likely take centuries for any noticeable drop.
Going meaningfully faster will require massive reforestation and maybe some geo-engineering.
So I'm asking you in the hopes that your argument will be understood correctly, instead of being misleading due to distorted interpretations.
