When Cooling Earth, Do It Right
November 3, 2020
With global warming showing little sign of slowing, scientists and policy-makers are looking anew at solar geoengineering to cool the planet, especially the injection of aerosols into the atmosphere to reflect some of the sun’s energy into space. But they worry about doing it right to avoid harmful side effects. For help, they can turn to an Issues article by a geoengineering expert and advocate who outlined basic principles to guide research on solar geoengineering, adding that it should be part of a broader research portfolio that includes climate change mitigation and adaptation.
