Inside the deadlock at the world's top climate science body
Summary
The IPCC is deadlocked over when to publish its next climate science reports, with member states split between a 2028 timeline and delays into 2029. The dispute could leave governments heading into the next UN climate talks without the latest scientific assessment of global warming, climate finance and emissions cuts.
Key Points
- IPCC member states are still split over a timeline for publishing the next round of climate science reports after nearly three years of debate.
- A bloc of countries wants the reports ready before the 2028 UN climate talks, while others argue the schedule is too tight for thorough scientific review and inclusion.
- The deadlock reflects wider tensions between wealthy nations, major emerging economies and poorer countries over climate responsibility, equity and development needs.
- The IPCC says its next review will include new chapters on climate finance and irreversible harm, but missing the 2028 deadline could weaken policymaking.
