A U.S. study is under way to evaluate several possible ways to limit climate change including solar radiation management and carbon dioxide removal. The study will primarily be an analysis of peer-reviewed literature, and will not involve any substantial new research, experimentation, or development of new geoengineering technology, spokeswoman Lauren Rugani of the National Academy of Sciences said.
"The project's main goal is to provide a technical evaluation of proposed geoengineering techniques such as carbon dioxide removal and solar radiation management, to determine what we know and don't know about their physical capabilities, technical feasibilities, known risks, and intended or unintended consequences," Rugani said.
The evaluation would include general comments on how using such technology may impact the environment, economy and national security. The study committee includes experts in oceanography, earth sciences, environmental sciences, remote sensing, global ecology, marine chemistry and geochemistry, public policy, history of science, atmospheric and climate science and national security, Rugani said.
