There are various potential ways to “geoengineer” the Earth to counteract global warming. Brightening clouds, putting a haze into the stratosphere, bringing cooler water up from the ocean depths: all are being studied. There is little doubt that at least one of these methods could, if used in concert with significant emission cuts, end the warming and bring temperatures back down sooner than emission cuts can on their own. But if a nation starts geoengineering, how should others react? Would they continue to cut emissions in the face of an alternative? What if geoengineering helped in some places but made things worse in others? Worries about justice, democracy and safety mean some want research into the area stopped. In an ever-hotter world would everyone comply with such a ban? This panel from SXSW 2023 discuss the various geoengineering methods under consideration and what the impacts and implications could be.
Featuring:
Kate Ricke, Scripps Institution of Oceanography and School of Global Policy and Strategy at UC San Diego
Peter Frumhoff, Senior Science Policy Advisor at the Woodwell Climate Research Center and Harvard University Professor
Oliver Morton, Briefings Editor at The Economist
Shuchi Talati, Founder & Executive Director, The Alliance for Just Deliberation on Solar Geoengineering
