Dan Visioni @danvisioni.bsky.social · 27/01/2026We looked at various drivers, including cooling-driven surface O3 changes, drivers of changes in particulate matter, and internal variability, combined with up to date exposure–response functions to understand the ultimate impacts. 110 0
Dan Visioni @danvisioni.bsky.social · 27/01/2026Main finding is that, overall, these feedback balance out and result in changes that are independent of injection rates: if you aim to cool more, you don't end up with worse or better health outcomes (but regionally this varies). Air quality is complicated and not always fully represented in ESMs... 110 0
Dan Visioni @danvisioni.bsky.social · 27/01/2026...and hopefully more detailed studies further down the line can help identify missing pieces. In our paper, we highlight what we think are the aspects where we think the response we find is robust, discussing CESM capabilities, and where there are margins for improvements (nitrogen, dust, etc.). 110 0
