GEOENGINEERING: ASSESSING THE IMPLICATIONS OF LARGE-SCALE CLIMATE INTERVENTION
“Geoengineering is a controversial issue because of the high degree of uncertainty over potential environmental, economic and societal impacts, and the assertion that research and deployment of geoengineering diverts attention and resources from efforts to reduce greenhouse gas emissions. The purpose of this hearing is to provide an introduction to the concept of geoengineering, including the science and engineering underlying various proposals, potential environmental risks and benefits, associated domestic and international governance issues, research and development needs, and economic rationales both supporting and op- posing the research and deployment of geoengineering activities. This hearing is the first in a series on the subject to be conducted by the Committee, with subsequent hearings intended to provide more detailed examination of these issues.
