IPCC:AR6

Browsing IPCC's Sixth Assessment Report (AR6)

The Sixth Assessment Report (AR6) comprises three Working Group contributions: Working Group I (The Physical Science Basis), Working Group II (Impacts, Adaptation and Vulnerability) and Working Group III (Mitigation of Climate Change) and a Synthesis Report.

The Synthesis Report integrates the three Working Group reports as well as the findings from the three cross-Working Group Special Reports prepared during this assessment cycle: Special Report on Global Warming of 1.5ºC (SR15, October 2018), Special Report on Climate Change and Land (SRCCL, August 2019) and Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC, September 2019).

During the AR6 cycle the IPCC also updated its methodologies with the 2019 Refinement to the 2006 Guidelines on National Greenhouse Gas Inventories (May 2019). For this representation here in MediaWiki, we have declared this report out of scope.

Climate Change 2023: AR6 Synthesis Report

A Report of the Intergovernmental Panel on Climate Change

The Synthesis Report integrates the three Working Group reports as well as the findings from the three cross-Working Group Special Reports prepared during this assessment cycle. Climate change is a serious and accelerating threat to human well-being and planetary health, but the window to secure a livable future remains open if transformative action is taken this decade.

Global Warming of 1.5°C

Special report

Cover SR1.5

Limiting warming to 1.5°C rather than 2°C would significantly reduce climate risks, but requires rapid, far-reaching, and unprecedented transitions in energy, land, transport, and industry by 2030.

Climate Change and Land

Special report
