The plan spans phases from computer simulations and lab work to progressively larger outdoor sulfur dioxide release experiments, and finally full-scale monitoring if deployment proceeds. Coordinated execution would take about a decade and cost roughly $370 million; uncoordinated efforts could take 20 years and $1.4 billion. The proposal is controversial: critics like signatories of the International Non-Use Agreement argue the core issues are governance and equity rather than technical uncertainty, and warn about risks like termination shock. Supporters, including former ARIA CEO Ilan Gur and Imperial College's Sebastian Eastham, argue outdoor experiments are necessary to resolve key scientific uncertainties responsibly. ## Full article daily.dev links to this article rather than hosting it.
