PrintModule 9: Geoengineering
In one sense, humans have been altering or “engineering” different aspects of the Earth since the earliest civilizations — but this has mainly been on a small scale. Now, the threats presented by climate change are leading to the development of a whole new set of schemes that seek to alter the global climate — a fairly ambitious task. Geoengineering is the term used to describe these schemes to intentionally modify or control Earth’s climate system, in order to reduce global warming. There are two general categories of geoengineering schemes — CO2 removal and insolation (sunlight) reduction.
