Governments have once again postponed a crucial decision regarding the timing of a significant climate science assessment, marking the third delay following protracted discussions at a meeting of the Intergovernmental Panel on Climate Change (IPCC) in Hangzhou, China. The meeting aimed to align the IPCC’s work with UN climate policy but ended without resolving persistent disagreements.
While officials reached a consensus on the outlines for the IPCC’s upcoming reports, no agreement was made on their delivery timeline, despite intensive negotiations that included a lengthy 30-hour session on the final day. The majority of participating nations, including European countries, Japan, and various small island states, supported a proposal to complete the scientific review process by August 2028. This timeline would allow the findings to contribute to the upcoming “Global Stocktake,” an evaluation of climate action under the Paris Agreement.
However, countries like China, Saudi Arabia, and India opposed this timeline, raising concerns about the process’s inclusivity. In a last-minute compromise brokered by the Chinese representatives, the assessment process was set to begin in 2025, with further discussions planned for the next IPCC meeting.
IPCC chair Jim Skea emphasized that despite the complexities involved, key scientific content had been clarified, showcasing the panel’s ability to build multilateral consensus. The current IPCC cycle, known as AR7, will compile vital climate science across three reports, focusing on the foundations of climate change, the vulnerabilities of affected systems, and potential mitigation strategies.
Previous assessments have notably informed significant agreements, such as those made at COP28, which marked a commitment to transitioning away from fossil fuels. As climate discussions evolve, the continuing role of major economies like the US and China remains heavily scrutinized, especially as the US has exhibited hesitancy in its international climate diplomacy under previous administrations.
Additionally, technical discussions during the meeting highlighted concerns regarding the emphasis on various methodologies for carbon removal technologies, with debates over the relevancy of marine geoengineering proposals. Many nations worried that elevating these controversial approaches could detract from the urgency of genuinely effective climate solutions.
Despite the setbacks, global advocacy remains strong, particularly for vulnerable nations facing the brunt of climate change impacts. Advocates like Greenpeace’s Zhe Yao stressed the pressing need for decisive action, criticizing delays that hinder progress against climate pressures faced by at-risk communities.
As the landscape of climate negotiations evolves, the hope is that continued dialogue and collaboration can yield solutions that address the urgent needs of vulnerable populations while effectively tackling the climate crisis on a global scale. It is crucial for nations to come together in unity, prioritizing meaningful action over extended discussions, to forge a path toward a more sustainable future.
