New Study of Geoengineering Raises New Worries
June 25, 2024
A cloud-modifying method proposed for blocking some sunlight in order to cool western coastal areas of the United States could work, at least initially, but also could cause severe adverse effects in the region and across other nations, according to a Guardian report on a new modeling study. The cautionary findings reinforce David W. Keith’s call in Issues for strengthening research on both solar geoengineering and possible policy and governance options. “Only an integrated research program,” he writes, “can hope to achieve the multiple objectives instrumental to making the science, policy, and politics of solar geoengineering work.”
