Geoengineering 2013
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.

Proposals
Pull up sunken nutrients to create CO2-capturing plankton blooms, then push new organic carbon into ocean depths before it reverts to CO₂.
Deep water supersaturated with methane can be degassed by lifting it to the surface.
Cloud seeding can induce fresh snowfalls, altering the albedo of underlying snow, rock or vegetation.
For worst-case scenarios we might need a "last chance option" in which we mimic the natural effect of aerosols on a longer time scale.
This proposal is focused to provide the essentials to families destined to walk that fine line between adaptation and migration.
CO2 scrubbing invariably requires power, the generation of which has already contributed to global emissions. Can this problem be solved ?
The walls of log houses is an easily accountable carbon reservoir. CO2, which is naturally captured by trees, could be safely stored there.
Earth's poles are heating up faster than elsewhere with Arctic ice declining. A shaped cloud of dust in low polar orbit could reverse this.
"PICKING UP THE TAB!"
Economical reef innovation could provide the beneficial processes we need to save our oceans' ecological system.
Government to subsidize painting of existing residential roofs to white and also provide a tax credit as a reward.
Geo-Safe(CDR)is a self-funded and effective Carbon Dioxide and Methane Removal Process where all benefits go directly back to the people!
Ocean Macroalgal Afforestation is not geoengineering!
