My main point is that if CO2 levels fall below 150 ppm there would be a mass extinction of land-based plants, and of all the animals who depend on this vegetation. If you care about life on the continents, and human life, this is a valid concern when people explore schemes to rapidly remove massive quantities of CO2 from the atmosphere.
- EamonnMR 8y agoIt is unlikely that we will accidentally lower CO2 levels too quickly.
- thebooktocome 8y agoMoreover, if we do happen to accomplish such a thing, it's easy to raise C02 levels; just burn more fossil fuels temporarily.
- EamonnMR 8y agoI wonder if we'll ever increase the biomass enough that we'll actually want to increase the total carbon in the system...
