New Report

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…

What Is Ocean Fertilization?

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.
