GENEVA/ADDIS ABABA – As the international community intensifies its efforts to address the escalating climate crisis, the Intergovernmental Panel on Climate Change (IPCC) is set to gather in Addis Ababa, Ethiopia, for its 65th Plenary Session. Scheduled from 12 to 16 October 2026, this high-level assembly marks a critical juncture in the organization’s Seventh Assessment Cycle, bringing together global scientific leaders, policymakers, and international stakeholders to refine the roadmap for the world’s most influential climate guidance.
The session is hosted by the United Nations Economic Commission for Africa (UNECA) and the Federal Democratic Republic of Ethiopia. It serves as a vital platform for aligning the latest scientific evidence with the urgent political requirements of a planet experiencing record-breaking temperatures and extreme weather events.
The Opening Session: Setting the Agenda
The official proceedings will commence on Monday, 12 October 2026, at 16:00 (UTC+3). The event will be held at the Ethiopian Meteorological Institute (EMI) in the Bole Sub City of Addis Ababa.
The opening ceremony is designed to emphasize the intersection of scientific research and actionable governance. IPCC Chair Sir Jim Skea will lead the address, joined by Ethiopia’s Minister of Water and Energy, Dr. Eng. Habtamu Itefa. The ceremony will also feature high-level diplomatic participation through video contributions from key international leaders:
- Prof. Celeste Saulo, Secretary-General of the World Meteorological Organization (WMO).
- Ms. Inger Andersen, Executive Secretary of the United Nations Environment Programme (UNEP).
- Mr. Simon Stiell, Executive Director of the United Nations Framework Convention on Climate Change (UNFCCC).
While the plenary sessions remain closed to the public and the media to ensure rigorous, unhindered deliberation, the opening session serves as the primary window for the global press to engage with the leadership of the IPCC. Journalists in Addis Ababa must register their attendance with Ms. Hirut Alemu at the EMI Public Relations office by the end of the day on Sunday, 11 October 2026.
A Chronology of the Seventh Assessment Cycle
The 65th Plenary Session is not an isolated event but a milestone in a meticulously planned multi-year scientific journey. The Seventh Assessment Cycle (AR7) began in July 2023, following the election of the new IPCC and Task Force Bureaus in Nairobi. Since then, the IPCC has rapidly accelerated its work to provide the evidence base needed for the next decade of climate action.
Key Milestones in the AR7 Timeline:
- January 2024 (Istanbul, Türkiye): The 60th Plenary Session formally approved the production of the three core Working Group contributions to the Seventh Assessment Report (AR7), covering the physical science basis, impacts/adaptation, and mitigation.
- July–August 2024 (Sofia, Bulgaria): During the 61st Plenary, the Panel finalized the outlines for the Special Report on Climate Change and Cities and the Methodology Report on Inventories for Short-lived Climate Forcers.
- February 2025 (Hangzhou, China): The 62nd Plenary resulted in the formal adoption of the structural outlines for all three main Working Group contributions to AR7.
- October 2025 (Lima, Peru): Member governments agreed upon the scientific content for the upcoming 2027 Methodology Report on Carbon Dioxide Removal (CDR) Technologies and finalized the 2026 workplan.
This disciplined approach ensures that by the time the Synthesis Report is released in late 2029, policymakers will have a coherent, comprehensive, and peer-reviewed picture of the climate trajectory for the remainder of the century.
Supporting Data: The Pillars of IPCC Assessment
To understand the significance of the Addis Ababa meeting, one must appreciate the sheer scale of the IPCC’s operation. Since its inception in 1988 by the UNEP and WMO, the IPCC has acted as the "gold standard" for climate science.
The Structure of Scientific Rigor
The IPCC operates through three distinct Working Groups, each tasked with isolating specific facets of the climate puzzle:
- Working Group I: Focuses on the physical science basis of climate change, providing the foundational data on greenhouse gas concentrations and atmospheric changes.
- Working Group II: Evaluates the impacts, adaptation strategies, and vulnerabilities of human and natural systems.
- Working Group III: Concentrates on the mitigation of climate change, assessing technological and policy pathways to reduce carbon output.
Supplementing these groups is the Task Force on National Greenhouse Gas Inventories, which establishes the methodologies used by nations to track their emissions. This infrastructure is supported by thousands of volunteer experts worldwide who distill thousands of scientific papers annually. This rigorous, multi-stage review process is what grants the IPCC its reputation for unparalleled objectivity and transparency.
Official Responses and Strategic Implications
The convening in Addis Ababa is particularly significant given the current global climate landscape. With the conclusion of the Sixth Assessment Report (AR6) in 2023—which provided the scientific bedrock for the First Global Stocktake at COP28—the pressure on the 65th Plenary to deliver clear, actionable data has never been higher.
Strategic Priorities for the 2026 Session
The 65th Plenary will address several critical policy-relevant topics:
- Carbon Dioxide Removal (CDR): As nations struggle to meet the Paris Agreement targets, the 2027 Methodology Report on CDR becomes a centerpiece of the current cycle. The Addis Ababa session will focus on the deployment and verification of these technologies.
- Urban Resilience: The Special Report on Climate Change and Cities (scheduled for March 2027) represents a pivot toward localized climate action. As more than half of the world’s population now lives in urban centers, the IPCC is prioritizing research that helps municipal leaders design climate-resilient infrastructure.
- Short-lived Climate Forcers (SLCFs): The methodology report on SLCFs, due in late 2027, will provide crucial insights into managing pollutants that have a high warming potential but a short atmospheric lifespan, such as methane.
The Role of Adaptation
Furthermore, the IPCC is currently developing a revision of the 1994 Technical Guidelines on impacts and adaptation. By integrating modern metrics and indicators, the Panel aims to provide a more sophisticated framework for governments to measure their progress in adapting to the unavoidable impacts of a warming world.
Conclusion: The Path Toward 2029
The 65th Plenary Session in Addis Ababa represents more than just a meeting of minds; it is a vital checkpoint for global survival. By finalizing the workplans for the Seventh Assessment Cycle, the IPCC is ensuring that the scientific community remains several steps ahead of the political curve.
As Sir Jim Skea and his colleagues convene in Ethiopia, the eyes of the international community are focused on the integration of these complex scientific reports into the broader climate policy landscape. With the final Synthesis Report slated for 2029, the work conducted in Addis Ababa will ripple through national legislatures, international treaties, and corporate boardrooms for years to come.
The science remains clear: the window for meaningful intervention is narrowing, and the role of the IPCC in providing the objective, rigorous data required to navigate this crisis has never been more essential.

Note: The IPCC is the United Nations body for assessing the science related to climate change. Its assessments provide governments at all levels with scientific information that they can use to develop climate policies, and they are a key input into international negotiations to tackle climate change.
