Last November, city leaders, policymakers and scientists, among others, came together to discuss cities’ roles in the climate crisis, in a conference held in Glasgow, Scotland, UK (optica-opn.org/news/gemm-at-cop26). The conference—“Cities Are the Key to the Climate Solution”—took place in parallel with the UN COP26 meeting in Glasgow, and was organized in part by the Global Environmental Measurement and Monitoring (GEMM) Initiative, an international project jointly supported by Optica and the American Geophysical Union.
