International Research Cautions on Geoengineering Methods
Study addresses concerns about melting ice after COP27 in 2022.
Proposed methods include atmospheric particle injection, submerged barriers, ice enhancement, glacier water extraction, and marine nutrient addition.
Methods face high costs, ecological risks, and practical challenges.
Lead author Martin Siegert says projects would cost $10B, likely fail, and delay emission cuts.
Study concludes rapid greenhouse gas reductions are the only viable solution.
Geoengineering could harm ecosystems, international relations, and climate efforts.
