Experts and author teams of the Intergovernmental Panel on Climate Change (IPCC) are meeting this week at the Universidad Católica in Santiago, Chile, to advance the first draft of the Working Group I contribution to the Seventh Assessment Report (AR7). Working Group I report covers the physical science related to climate change.
The meeting, scheduled from 21 to 24 April, is the second time the authors will be meeting in person following the first meeting held jointly with Working Group II and III in Paris in December 2025 where they began their work. The authors will meet two more times during the report preparation process to develop and refine the draft in line with IPCC’s principles and procedures
