|English: The SPICE project will investigate the feasibility of one so-called geoengineering technique: the idea of simulating natural processes that release small particles into the stratosphere, which then reflect a few percent of incoming solar radiation, with the effect of cooling the Earth with relative speed.

The NAS website describes the study as an investigation into "a limited number of proposed geoengineering techniques, including examples of both solar radiation management (SRM) and carbon dioxide removal (CDR) techniques."
The purpose of this is to comment "generally on the potential impacts of deploying these technologies, including possible environmental, economic, and national security concerns", the website claims.
Solar radiation management (SRM) is a theoretical branch of geoengineering which moots the idea of reflecting sunlight in an attempt to block infrared radiation and halt rising temperatures.
The cost of the project is reported to be $630,000, which NAS is splitting with the CIA, the National Oceanic and Atmospheric Administration, and NASA reports say. Read more >>
