the problem with climate change is the wild swings in weather - if you want to stabilize and buffer these swings, you need to maximize biomass. having a mature forest ecosystem acting as a carbon/nitrogen buffer does a lot of good, but in a way that is difficult to measure

I think we get tunnel vision on CO2 ppm because it's a metric with a nice clean causative effect (greenhouse), but more energy on earth is not what's actually causing us grief, we've destroyed most of the mature ecosystems and decimated total biomass, and we are surprised that this causes issues with the total ecosystem because we consider atmospheric problems somehow unrelated to all the living things participating in chemical cycles with that atmosphere. we need more buffer wherever we can get it, and I hate to see someone poo-pooing ecosystem restoration in favor of carbon sequestration.
