Why it matters
This session is essential for coordinating global climate research strategies as the IPCC progresses through its seventh assessment cycle. The decisions made regarding funding and project timelines will shape the scientific outputs used to guide international environmental policy.
The session follows the formal start of the seventh assessment cycle in July 2023. It aims to advance research efforts that include upcoming publications like the Special Report on Climate Change and Cities expected in March 2027.
The players
Intergovernmental Panel on Climate Change
