Climate body faces deadlock over timeline of new reports

Why in the News

Report timelines at the Intergovernmental Panel on Climate Change (IPCC) are usually approved in “a matter of minutes”, but after nearly three years of debate its members still cannot agree when to publish the next assessment, a deadlock unprecedented in its history. Representatives of its 195 member states were expected to meet in plenary at Addis Ababa, seen as the last chance to fix dates before the UN climate talks of November 2028.

What is the IPCC, and why does the timing matter?

1. What it is: The IPCC is the UN body that reviews published climate science for governments. It works like an examiner who reads all the research and writes the textbook negotiators use.
2. Policy weight: Its assessments have informed every major UN climate agreement for three decades.
3. Three reports: The next (Seventh) assessment cycle will cover the extent and causes of climate change, vulnerabilities and adaptation, and options to stop warming getting worse.
4. The 2028 link: At the November 2028 talks, governments assess progress towards the Paris Agreement (2015) goals in a global stocktake, which guides climate finance and national emission targets.
5. The takeaway: Without agreed dates, countries could decide the next phase of action without consensus on critical questions, such as how far some warming might be reversible.

What are members divided over?

1. Chairs’ work plan: Scientists chairing the report groups proposed approving all three reports by September 2028. A French co-chair said the plan rests on workload, not the summit’s timing.
2. Opponents’ demand: Countries opposing the plan want the second and third reports pushed into 2029.
3. Coalition alarm: A coalition of countries pushing for more robust action is alarmed that the reports might miss the 2028 talks.
4. Political pressure: Some governments criticise climate policies as hurting industrial competitiveness or barring emerging economies from cheaper, more polluting fuels.
5. US exit: The United States, the IPCC’s biggest funder, quit the organisation in January 2026.

Why do India and other developing countries want more time?

1. Developing country bloc: India, Kenya, Saudi Arabia, Russia and China want more time so that scientists from less resourced countries can contribute meaningfully.
2. Practical barriers: Some scientists struggle to publish new research in time, or to take time off regular jobs for unpaid IPCC work.
3. Thin representation: Developing countries have long argued their perspectives are underrepresented, because fewer of their experts take part and their researchers have fewer resources to publish peer reviewed studies.
4. India’s position: India’s representative at the IPCC called it “short-sighted” to tie the body’s value solely to the 2028 talks. He said issues of “equity and inclusivity” are in some instances “simply ducked”.

Challenges

1. Consensus rule: The IPCC decides by consensus among member governments, so a determined group can stall even a routine work plan.
2. Funding gap: The loss of its biggest funder strains the budget that supports authors and meetings.
3. Science without dates: Negotiators may enter the 2028 review relying on the Sixth assessment, completed in 2023.
4. Credibility risk: A science body seen as split along political lines loses authority with both sides.

Way Forward

1. Staggered approval: Agree firm dates now, letting the first report precede the 2028 talks if the others need more time.
2. Fund participation: Expand the IPCC Trust Fund support that pays for developing country experts to attend and contribute.
3. Wider evidence base: Use the IPCC’s existing provision for regional and non peer reviewed literature to capture research from less resourced countries.
4. Replace US money: Other members should widen contributions to cover the US withdrawal.

Conclusion

The IPCC’s next assessment has no agreed timetable, and the dispute is as much about whose science is counted as about dates. Whether the Addis Ababa plenary fixes publication dates before the next global stocktake is the milestone to watch.

Back2Basics: Global stocktake

1. What it is: A periodic review under Article 14 of the Paris Agreement of collective progress towards the agreement’s goals, held every five years.
2. Inputs: It draws on the best available science, including IPCC reports, and on submissions from countries.
3. First stocktake: It concluded at COP28 in Dubai (2023) with a call to transition away from fossil fuels in energy systems and to triple renewable capacity.
4. Purpose: Its outcome informs each country’s next Nationally Determined Contribution (NDC), its national climate pledge.

Matching Previous Year Question

“[2026] Consider the following statements with reference to India’s response to climate change: I. India’s LT-LEDS is a crucial tool for achieving net-zero emissions by 2070. II. India’s BUR-4 (Dec 2024) recorded ~8% decrease in GHG emissions in 2020 over 2019. III. Climate-resilient development necessarily depends on quick and short-term achievement of emission reduction targets. Which of the following relationships is/are correct? 1. Statement I is empirically supported by statement II 2. Statement III contradicts the approach implicit in statement I 3. Statement I and statement III together establish the premise of long-term sustainability (a) 1 only (b) 1 and 2 (c) 2 and 3 (d) 3 only ANSWER: B”
