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…

How large is the design space for stratospheric aerosol geoengineering

First published in Earth Systems Dynamics, January 25, 2022. Summary... Managing multiple climate goals simultaneously with stratospheric aerosol cooling. Small cooling is easier than large cooling with more choices of strategies available. Zhang and MacMartin et al., How large is the design space for stratospheric aerosol geoengineering, Earth…

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…
