The Summary for Urban Policymakers (SUP) Volume IV synthesizes findings from the IPCC’s Working Group I, II, and III reports to give an overview of the state of knowledge on the physical science of climate change; impacts and risks from climate change; and the solution space covering adaptation and mitigation action. Collectively, SUP Volume IV discusses the findings of each working group report from the IPCC Sixth Assessment Report (AR6) for an urban context.
