The goal of reaching “Net Zero” global anthropogenic emissions of carbon dioxide sounds overwhelmingly difficult. While humanity continues producing CO2 at increasing rates (with a temporary pause during COVID), how can we ever reach the point where these emissions start to fall, let alone reach zero by 2050 or 2060?

What isn’t being discussed (as far as I can tell) is the fact that atmospheric CO2 levels (which we will assume for the sake of discussion causes global warming) will start to fall even while humanity is producing lots of CO2.

Why is that? The reason is due to something called the CO2 “sink rate”. It has been observed that the more CO2 there is in the atmosphere, the more quickly nature removes the excess. The NASA studies showing “global greening” in satellite imagery since the 1980s is evidence of that.

I don’t understand why this issue is not being discussed. All of the Net Zero rhetoric I see seems to imply that warming will continue if we don’t cut our CO2 emissions to essentially zero. But that’s not true, because that’s not how nature works.
