Summary
The IPCC's 195 member states met in Addis Ababa from 12 to 16 October 2026 for the 65th plenary, with the timeline for the Seventh Assessment Report (AR7) on the agenda. The working-group co-chairs have proposed approving all three main reports by September 2028, in time for the second Global Stocktake under the Paris Agreement, due to conclude in November 2028.
India, Kenya, Saudi Arabia, Russia and China want the second and third reports moved into 2029. They argue that scientists from less-resourced countries need more time to publish and contribute to unpaid IPCC work. Climate-vulnerable countries in the High Ambition Coalition warn that missing 2028 would leave negotiators relying on outdated science.
The deadlock is unprecedented and it follows the US exit in January 2026, which removed the IPCC's largest funder.
WHY IT MATTERS FOR UPSC & STATE PCS
The IPCC's 65th plenary session in Addis Ababa is seen as the last chance to agree AR7 publication dates that fall before the November 2028 Global Stocktake. Member states remain divided over whether to finish the reports by 2028 or extend into 2029.

The Deadline Is Not the Real Dispute
The commitment Article 14 of the Paris Agreement requires a Global Stocktake every five years to assess collective progress, informed by the best available science.
The first concluded at COP28 in December 2023. The second is due to conclude at COP33 in November 2028. The IPCC exists to supply that science. Its working-group co-chairs have proposed approving all three AR7 reports by September 2028. French co-chair Robert Vautard says the plan reflects workload, not the summit date.
The reality After nearly three years of debate, the 195 member states have not agreed.
India, Kenya, Saudi Arabia, Russia and China want the second and third reports - on adaptation and on mitigation - moved into 2029. The High Ambition Coalition of more than 30 countries warns that relying on reports from 2021-22 would undermine the stocktake. Reuters, speaking with more than a dozen scientists, negotiators and observers, reported that the deadlock has no precedent in the IPCC's history.
Where the
chain actually breaks This is not a dispute about science. It is a dispute about who gets to do the science in time. IPCC authorship is unpaid. A researcher from a less-resourced country must take time away from a salaried job and often struggles to publish the peer-reviewed work the IPCC assesses before its cut-off dates.
Carbon Brief's analysis shows only 30-40% of authors across the AR6 cycle came from the Global South. Working Group I, the physical science report, has the lowest developing-country share. Thiagarajan Jayaraman, who represents India at the IPCC, argues that this is why questions of equity and inclusivity are sometimes simply avoided in IPCC reports.
He calls it short-sighted to value the IPCC only for its input to the 2028 talks. The specific failure point is capacity: funding and time for Global South scientists. A compressed timeline does not create that capacity.
It shortens the window that under-resourced researchers already find too narrow.
The honest counterweight India's case has substance, but its company makes it harder to argue.
Sitting beside Saudi Arabia and Russia - governments that face pressure over fossil fuels - invites the charge that equity is cover for delay. The stakes for vulnerable countries are real. The Global Stocktake shapes the next round of national emission targets and climate finance.
A stocktake without fresh science weakens the case for higher ambition at exactly the wrong moment. The money problem makes both positions harder. The US, which withdrew in January 2026, had given 1.445 million CHF in 2024, about 28% of the IPCC Trust Fund's income.
The resources that could speed up Global South participation are shrinking just as that participation is being argued over.

A direct diagnosis of the bottleneck: why unpaid authorship and publication cut-offs, not scientific disagreement, explain the 30-40% Global South share.
How the AR7 timeline feeds the 2028 Global Stocktake and what negotiators would lose if they relied on AR6-era reports.
The geopolitics of the delay coalition: where India's equity argument genuinely differs from the positions of Saudi Arabia and Russia.
A funding-and-timeline compromise that could meet both the 2028 deadline and the inclusion demand.
