The Intergovernmental Panel on Climate Change concluded a week-long meeting in Addis Ababa without establishing a firm timeline for its seventh comprehensive assessment report on climate science. The report, known as AR7, was originally scheduled for publication in 2028, marking seven years after the previous assessment released in 2021. However, disagreement over the publication date has created uncertainty about the scientific guidance available to governments ahead of the Cop31 climate summit scheduled for next month.
A coalition of governments including Saudi Arabia, Russia, India, China, and Kenya has objected to the 2028 timeline, contending that climate science has been dominated by developed nations and that this influence has affected the conclusions drawn. These countries argue that postponing the report to 2029 or beyond would allow for greater inclusion of scientific contributions from developing regions. Scientists and climate experts, however, express concern that delaying the report would prevent it from informing the next cycle of emissions reduction pledges scheduled for discussion at the Cop33 climate summit in late 2028, a critical juncture under the Paris agreement framework for assessing whether national commitments align with temperature goals.
Proponents of the 2028 deadline note that most research intended for inclusion in AR7 has already been completed and is undergoing review. The IPCC maintains that it implements rigorous measures to include scientists globally and actively works to prevent developed-country bias in its assessments. Critics of the delay proposal also observe that the nations advocating for postponement possess substantial scientific capacity and resources that could have been directed toward expanding developing-country research contributions.
Civil society organizations remain divided on the matter. Some view any postponement as an obstacle to emissions reduction progress, while others contend that ensuring equitable participation and representation in scientific processes carries equal importance to meeting deadlines. One proposed compromise would preserve the 2028 publication date for the report’s physical science section while allowing subsequent sections addressing climate impacts and solutions to be delayed for expanded input.
Scientists from developing countries, including representatives from China and India, have issued a public commitment to continue their work on the assessment regardless of the outcome. IPCC leadership has pledged to reconvene discussions at the earliest opportunity, with the dispute expected to feature prominently in the upcoming climate negotiations.
