by Climate and Clean Air Coalition Secretariat (CCAC) - 23 October, 2025

Building on a strong record of contribution to the IPCC’s work, members of the CCAC’s Scientific Advisory Panel (SAP) and wider scientific community are joining the Working Groups of the upcoming Seventh Assessment Report (AR7), continuing their leading role in advancing global climate science.  Several have been selected as lead and coordinating lead authors on two of the three Working Groups of the upcoming Seventh Assessment Report (AR7) of the Intergovernmental Panel on Climate Change (IPCC). The Special Report on Climate Change and Cities and the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers are also ongoing.  

IPCC Reports provide an authoritative assessment of the state of knowledge on climate science, mitigation and adaptation responses to climate change. IPCC reports are an important input for policy making and international climate negotiations.
