Researching strategies to reduce solar radiation on Earth
Solar radiation management (SRM) or “solar geoengineering” is a theoretical approach to mitigating some of the adverse impacts of climate change by reflecting inbound sunlight back into space and cooling the atmosphere. Such large-scale, deliberate climate interventions have potentially significant and wide-ranging implications, yet the associated efficacy and risks remain insufficiently understood.
How it Works
Harvard’s SGRP program is one of the leading global efforts to model the impacts and study the governance of SRM. Unless policy and science conspire to radically reduce emissions in the coming years, hundreds of millions of people around the world will be at greater risk of disease, draught, flooding, and death in the near future. In that scenario, knowing if and how to shade sunlight will prove critical.
Harvard’s SGRP employs Harvard’s convening power to bring together scientists, environmental leaders, and government officials to discuss the technology and its governance. The program produces research that advances the science and technology frontier while disseminating ideas taken up by other researchers and government research programs.
