I am just asking whether geoengineering has been demonstrated as a feasible solution to reverse trends of global warming and anthropogenic greenhouse gas emissions. Geoengineering proposals typically aim to reduce the global greenhouse effect through several hypothetical means (like increasing cloud albedo.) http://www.geoengineering.ox.ac.uk/www.geoengineering.ox.ac.uk/what-is-geoengineering/what-is-geoengineering/ http://www.geoengineering.ox.ac.uk/www.geoengineering.ox.ac.... Dykes and dams that curtail flooding of coastal regions can be monumental undertakings but aren't typically referred to as "geoengineering." Hydropower from a dam could be a good way to reduce carbon emissions, but again wouldn't be considered geoengineering.
