 This study uses a joint sensitivity modelling to estimate the global surface temperature changes associated with national scale carbonaceous aerosol cook stove emissions, finding that removing these emissions could result in a central estimate of 0.06 k cooling. The study also identifies countries with the highest emissions and largest temperature impacts, as well as those that would provide the most efficient cooling from a switch to fuel with a lower BC emission factor. These results can inform climate impact assessments for cook stove initiatives across the world. This article was authored by Forrest Lacy and Daven Hens.
