Global climate science body fails to set review timeline

The gathering of member nations representing the Intergovernmental Panel on Climate Change (IPCC) ended without a consensus on scheduling the publication of its forthcoming scientific review, according to sources familiar with the closed-door discussions.

The inability to establish a firm timeline for the next assessment report represents a setback for the international body tasked with synthesising peer-reviewed climate research. The IPCC's previous major report, released in 2021, has served as a key reference point for policymakers negotiating climate action commitments globally.

The disagreement over timing reflects broader tensions within the IPCC membership, where countries balance competing interests in how quickly new climate findings are synthesised and disseminated. Some nations have advocated for expedited reviews to inform upcoming climate negotiations, while others have sought more flexibility in the assessment schedule.

The delayed agreement underscores the complex diplomatic negotiations required to advance international climate science cooperation. The IPCC's assessments carry significant weight in shaping climate policy frameworks, including those under discussion at upcoming international climate conferences. The organisation is expected to revisit the timeline question at future plenary sessions.
