Atmospheric Chemist Susan Solomon Awarded the 2026 Tang Prize in Sustainable Development, Unraveling the Mystery of the Ozone Hole and Advancing Global Environmental Governance

Contributing sentiments towards policy:

60% : Her proposed mechanism of heterogeneous chemical reactions showed that, under the extremely cold conditions of the Antarctic stratosphere during winter and spring, polar stratospheric clouds (PSCs) form, and the surfaces of their ice crystals provide highly effective reaction sites.
50% : Her major contributions include proving that chlorofluorocarbons (CFCs) were indeed the cause of the widening ozone hole in Antarctica; proposing the heterogeneous chemical reactions that explain ozone hole formation; demonstrating that the impacts of CO₂ emissions are largely irreversible for more than 1000 years; and co-leading the production of the United Nations Intergovernmental Panel on Climate Change (IPCC)'s Fourth Assessment Report on the Physical Science Basis of Climate Change, which comprehensively synthesized key knowledge in climate science.
