ADDIS ABABA, 17 October 2026 — The Intergovernmental Panel on Climate Change ended a key meeting without agreement on when to publish its next major scientific assessment, leaving a long-running dispute over the review timetable unresolved.

The delay follows nearly three years of disagreement among governments about the time needed to prepare the report and ensure that scientists from countries with fewer resources can participate meaningfully.

The IPCC’s assessments provide a shared scientific basis for climate policy and are closely watched by governments preparing emissions plans, adaptation strategies and international negotiations.

The impasse comes as countries work toward future UN climate talks and assess progress under the Paris Agreement. A delayed assessment could reduce the time available for policymakers to incorporate updated scientific findings into decisions.

Delegations disagreed over how quickly the process should move. Some countries called for a faster timetable, while others argued that a longer schedule was needed to support inclusive scientific participation and a robust review.

The panel said discussions on the schedule and budget remain open and are expected to resume. Reaching a workable agreement will require balancing scientific rigour, participation from all regions and the need for timely evidence to guide climate action.
