Blocking the Sun: Study Looks at Costs of 6 Geoengineering Schemes

As the planet warms and the world continues to emit greenhouse gases at a searing pace, some argue that geoengineering ideas are rapidly becoming attractive, if not downright necessary. For the uninitiated, the Royal Society defines geoengineering as (pdf) "The deliberate large-scale intervention in the Earth's climate system, in order to moderate global warming." In other words, hack the planet . One of the two main categories of geoengineering is solar radiation management, or SRM. (The other is the direct removal of carbon dioxide from the atmosphere.) The idea is to mimic what volcanos do naturally, by putting aerosol particles into the stratosphere on a massive scale. For example, when Mount Pinatubo erupted (image, above) in 1991, the cloud that encircled the planet caused an overall cooling of about half a degree. An argument has been raging for years now about the ...
