Geoengineering | Atmospheric Chemistry Observations & Modeling: National Center for Atmospheric Research
Geoengineering global and regional climate and weather has become an emerging topic in recent years. Delayed actions to reduce greenhouse gas emissions are projected to have irreversible effects on Earth’s climate and weather events with dire consequences for society and ecosystems. Geoengineering could be an opportunity to mitigate the worst impacts until emission and greenhouse gas concentration reductions have been effective. In particular, approaches that globally reflect sunlight have a large potential to reduce global temperatures based on recent model studies. At this time, however, it is not known if geoengineering is a viable solution, and a lot of work is needed to understand potential benefits, side effects, and risks of different approaches, in order to appropriately inform society and stakeholders.
