Anthropogenic climate change is already increasing the risk of extreme weather impacts to people and natural systems. While CO2 emission reduction provides the best-studied path to minimize negative outcomes, implementation is far from straightforward. Climate interventions (geoengineering) have been proposed to mitigate some of the negative impacts of warming –especially in the near-term alongside decarbonization– but pose significant additional risks and uncertainties. I will present a broad overview of some climate intervention schemes and a deeper dive into so-called marine cloud brightening, including technical feasibility and the impacts of low cloud variability on weather extremes.
