Climate science panel pauses meeting without setting next report timeline

The United Nations’ climate science panel ended a meeting in Addis Ababa without agreeing on when it will publish its next major assessment of climate research. The Intergovernmental Panel on Climate Change said Friday that talks on the publication schedule and its budget remain open, and that deliberations will resume at the earliest opportunity.

The IPCC does not conduct original climate research. It reviews and summarizes published studies through reports written by hundreds of scientists and approved by member governments. Those assessments are used to inform national climate plans and international negotiations, and have been cited in legal cases.

The unresolved schedule matters because governments are due to assess progress toward the goals of the 2015 Paris Agreement at U.N. climate talks in November 2028. Reuters reported that the latest IPCC review may not be ready in time for that global stocktake unless countries settle on dates soon.

The disagreement reflects competing concerns about both speed and inclusion. A coalition of more than 30 countries has pushed for reports to be ready before the 2028 talks, arguing that negotiators need current scientific findings. Other countries, including India, Kenya, Saudi Arabia, Russia, and China, have asked for more time so scientists from less-resourced countries can contribute meaningfully.

Scientists in lower-income countries may have difficulty producing research quickly enough to meet a tight schedule, or taking time away from paid work for IPCC assignments. Kenya’s climate representative, Joyce Kimutai, told Reuters that a process that moves too quickly could become less inclusive. The disagreement is therefore partly about how the panel can maintain broad participation while still delivering updated assessments on time.

The meeting ran beyond its planned end, and delegations from some least-developed countries and small island states had to leave, Reuters reported, citing the IPCC’s statement. That left the panel without a final agreement. The IPCC did not immediately announce a date or format for the next round of talks.

The panel’s seventh assessment cycle is already underway, and its working groups are preparing reports on the physical science, impacts and adaptation, and mitigation. The timing debate concerns when those reports will be released, and whether the full body of work can inform the 2028 review of global progress.

The delay does not erase existing climate research or change the findings of earlier IPCC reports. But without a timeline, governments may enter the 2028 talks without the next shared assessment. Countries will continue to use other research and national data, while the IPCC’s members work to resolve the schedule and budget questions.
