Climate Change 2021 : The physical science basis : Working Group I contribution to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change

Abstract

This Working Group I contribution to the IPCC’s Sixth Assessment Report covers important new advances in climate science that provide invaluable input into climate negotiations and decision-making, with an emphasis on key conditions that, from a physical science basis, are needed to limit global warming and inform risk assessment and regional adaptation. The report was welcomed at the 26th Conference of the Parties to the United Nations Framework Convention on Climate Change.
