The U.S. government has moved one step closer to turning science fiction into reality. On Wednesday, the federally funded National Academy of Sciences released a new report laying out six avenues to alter the oceans in an attempt to suck more carbon dioxide out of the sky and store it for centuries to come.
The ideas explored in the 300-page, peer-reviewed report include using electrical currents on seawater and dumping iron in the ocean to encourage massive plankton blooms. All six are far from ready for primetime, but the report is essentially a roadmap for a research program and legal framework for the techniques.
