Technically Speaking: Hacking the Planet
My goal here, as usual, is to focus on the new language being generated by geoengineers and others in this burgeoning field, and there's plenty of it. The overall goal of solar radiation management (or SRM)--the various schemes to reflect sunlight back into space and thus reduce global warming--is global dimming, which is the gradual reduction in the amount of sunlight reaching Earth's surface. One way to do this is to increase Earth's overall reflectivity, which is also called its albedo, so this form of planet hacking is known as albedo engineering. Examples of proposed projects include cloud brightening, increasing the reflectivity of marine clouds (also called cloud whitening); creating a stratoshield through stratosphere doping.... These two procedures are linked as carbon capture and storage, or CCS. Strategies include adding nutrients to the ocean to increase the number of organisms that can capture carbon, known as ocean nourishment (when the nutrient is iron, this technique is also called iron fertilization); making artificial trees with plastic "leaves" that capture carbon; creating carbon sinks, reservoirs that store carbon; injecting carbon into underground geological structures (geosequestration) or into biological entities (biosequestration), particularly a form of charcoal called biochar; and pumping carbon into the deep ocean, where it dissolves (ocean dissolution).

Now that we have a special language for geoengineering, we're ready for groupthink!
