英文摘要	As the climate crisis worsens, pressure is mounting for world leaders to accelerate climate action. A National Academies of Science, Engineering and Medicine report ([ 1 ][1]) released in March recommends that the United States invest unilaterally to expand research on solar geoengineering, a set of controversial proposed strategies to cool the planet by reflecting sunlight back to space. However, unilateral, preemptive research without broad public participation, and before a global governance structure is established, risks exacerbating international conflict and undermining progress on energy system transformation away from fossil fuels in the highly contested and politicized landscape of global climate policy ([ 2 ][2]–[ 4 ][3]). The idea of a technical intervention to counter global warming may have some appeal, but the social, political, and environmental risks associated with solar geoengineering research need to be prioritized in policy discussions ([ 2 ][2], [ 5 ][4], [ 6 ][5]). Given the dangers of advancing solar geoengineering ([ 7 ][6]), including further concentrating power among elites ([ 2 ][2]) and deterring mitigation efforts ([ 4 ][3]), inclusive processes for public deliberations on whether, when, and how public funding should be provided to support climate manipulation are essential. Advocacy for solar geoengineering research continues to be dominated by white male scientists from the Global North funded by tech-billionaires and elite philanthropy ([ 8 ][7]). More diverse voices are needed to expand public discourse beyond the narrow technocratic narrative that limits authentic deliberation about the risks. The United States is already the world leader in solar geoengineering research, but given widespread distrust of the country's leadership on climate change ([ 9 ][8]), and the legacies of unilateral US action in international affairs, fear of US unilateralism in advancing solar geoengineering technology is likely to increase risks of militarization or securitization of this planetary-scale intervention ([ 10 ][9]). Research on solar geoengineering, therefore, if it is to proceed, needs to be multilaterally governed under the United Nations systems ([ 11 ][10], [ 12 ][11]). Rather than establishing a unilateral US research program on global manipulation of Earth's climate, the Biden/Harris administration should expand US investment in multilateral, coordinated efforts to reduce fossil fuel reliance, advance global climate action, and commit to climate justice. 1.
