Sciencewise, a UK public dialogue program, summarized a 2014 dialogue on geoengineering. The dialogue involved 85 public participants and 74 experts over 14 months to inform research funding. Geoengineering aims to counter climate change through large-scale interventions, but raises moral, social, and environmental concerns. Participants cautiously supported research but emphasized linking it to emissions reductions and respecting natural systems. The dialogue influenced two funded projects to include public engagement components.
