New report “High level review of a wide range of proposed marine geoengineering techniques” comprehensively examines a wide range of marine geoengineering techniques to remove carbon dioxide from the atmosphere or boost the reflection of incoming solar radiation to space (albedo modification) or in some cases both. Further, the report recommends a) that a coordinated…

In 2012, OCB released a position statement regarding its stance on commercially driven ocean fertilization experiments that do not adhere to international protocols. OCB continues to be in support of scientifically rigorous, well-controlled ocean fertilization experiments that comply with international protocols for ocean dumping and marine pollution.

Ocean fertilization is a form of geoengineering (large-scale human actions to deliberately manipulate environmental systems) that involves adding nutrients to the upper (sunlit) layers of the ocean to stimulate phytoplankton activity (photosynthesis) in an attempt to draw down atmospheric CO2 levels.

The National Research Council released pre-publication versions of two reports Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration and Climate Intervention: Reflecting Sunlight to Cool Earth (4-page brief available here)

A 2013 study addresses geoengineering impact of open ocean dissolution of olivine on atmospheric CO2.
