A new paradigm from the Arctic

(From Moore 2025) "The prevailing “consequences-based paradigm” defines the role of climate scientists as informing the public about the negative effects of climate change, assuming this will mobilize political action to reduce emissions. Under this paradigm, research into strategies other than decarbonization is often seen as counterproductive, an…

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…
