Climate-cooling technology could help rein in global heating and its impacts, say backers, but critics warn it carries serious and unknown risks, with some calling for research to stop.

"I do see it as a likely option" if plans to cut emissions fall short and dangers grow, said Emmi Yonekura, a researcher on the risks of climate "geoengineering" https://news.trust.org/packages/geoengineering at RAND Corporation, a military-focused policy think-tank, during an online event. But the technology, which mimics the sky-darkening effect of volcanic eruptions, also carries serious and unpredictable risks, critics say - with some scientists so worried that they believe research should stop and outdoor tests be banned.
