What climate-engineering initiatives might be feasible, especially to avoid methane feedbacks caused by global warming?

Climate CoLab members are invited to read Comments by Expert Reviewers on the Geoengineering Proposals

The IPCC defines geoengineering as “intentionally modifying the Earth’s climate at large scale.” This contest invites proposals on all approaches to geoengineering, with particular interest in ideas that would be effective in limiting warming contributions from excitation of positive methane feedbacks in the Earth’s environment.
