The Intergovernmental Panel on Climate Change (IPCC) has officially opened registration for experts to review the First Order Draft of its Seventh Assessment Report Working Group II contribution. The draft report, which includes 20 chapters, evaluates global climate change vulnerability.
Why it matters
The expert review process is designed to ensure the scientific rigour, balance, and accuracy of findings by incorporating a wide range of academic and institutional perspectives. This step is critical in the development of the comprehensive assessment before the final synthesis release.
The draft report is comprised of 20 distinct chapters developed by experts following an initial meeting in May 2026. This review focuses on assessing accuracy, balance, and clarity within the document.
The players
Intergovernmental Panel on Climate Change
This United Nations body provides regular scientific assessments on climate change, its implications, and future risks to the global environment.
The details
Experts from around the world are invited to register online to provide feedback on the draft, which authors will then address alongside government comments. The process follows a foundational meeting held earlier this year that established the current report framework.
Timeline
May 2026: Authors met to prepare the initial report draft.
9 October 2026: The expert review period officially begins.
20 November 2026: Deadline for experts to register for participation.
4 December 2026: The expert review period concludes.
Late 2029: The Synthesis Report of the Seventh Assessment Report is scheduled for release.
The Big Picture
The current registration process follows the established methodology for developing the IPCC Seventh Assessment Report. This milestone confirms that the research cycle is moving toward its scheduled completion in 2029.
This development allows for broader oversight of the data that eventually informs global climate policies and environmental mitigation strategies. The feedback gathered during this period helps ensure the final reports provide a precise basis for international climate decision-making.
The takeaway
The IPCC continues to rely on a collaborative review model to maintain scientific consensus on climate vulnerabilities. Interested professionals should ensure they register before the November 20, 2026, deadline to participate in the feedback process.
What happens next
The expert review period will officially close on 4 December 2026, after which authors will begin incorporating feedback from experts and governments into the next iteration of the report.
