Carbon-cycle feedback emissions reduced with reduced warming, Hausfather and Betts 2024

Hausfather and Betts show natural feedback emissions with SSP 8.5 can be up to nearly 700 ppm CO2 or about 5,000 Gt CO2, but generally between 100 and 350 ppm CO2 or 780 to 2,700 Gt CO2. See figure, “Change in CO2 concentration when including carbon-cycle feedback uncertainties.”…

Geoengineering Reduces Atmospheric CO2 Burden – Friedlingstein 2006

Summary - Reduced natural system sequestration with warmer temperatures causes extra carbon to remain in the sky. Any cooling, natural or human-caused, reduces natural feedback emissions which reduces the atmospheric carbon burden. Geoengineering does indeed reduce the atmospheric Greenhouse gas concentration. Abstract “Eleven coupled climate–carbon cycle models used…

Geoengineering Reduces Cumulative CO2 – Keith 2017

Summary - "If solar geoengineering were used to hold radiative forcing constant under RCP8.5, the carbon burden may be reduced by ~100 GTC, equivalent to 12–26% of twenty-first-century emissions at a cost of under US$0.5 per tCO." It is also important to note that all other warming related responses…
