EPIC Lunch & Learn: Marine Cloud Brightening for Climate Impact Attenuation

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.
