What initiatives, policies, and technologies can counteract the effects of rising greenhouse gases, whether or not emissions are reduced?

The Intergovernmental Panel on Climate Change defines geoengineering as “intentionally modifying the Earth’s climate at large scale.” Lack of effective action on climate change has led some scientists, chemists and engineers to investigate a variety of technical interventions to counteract some of the effects of rising atmospheric greenhouse gases, without reducing emissions. Geoengineering strategies can operate at a global or local level and commonly fall into one of two broad categories: solar radiation management or carbon dioxide removal.
 

You are invited to submit your proposal here for geoengineering outside of the contest period. Workspace proposals will not be evaluated until a new contest on this topic opens. This is a space to try out new ideas, share your work, connect with other members and recruit collaborators, share your work, engage support, and invite a global community to review and help develop your proposal.
