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.
Industrial ocean based system for algae production, powered by wave, tide, current and sun, aim to fix more CO2 than total human emissions
