Forecast for Solar Geoengineering
June 6, 2020
Solar geoengineering—using technology to reflect a portion of sunlight back into space—may become necessary to limit climate change, says a onetime leader in the field, but “more research is needed to make anything akin to an informed deployment decision, and any process of moving toward deployment will be messy.” Issues has regularly followed these matters, exploring basic principles to guide research and decision-making, the importance of global collaboration, and the need to avoid vested interests among researchers and groups deploying geoengineering technologies.
