Governments have delayed again a decision on timing for IPCC climate science reports due to unresolved disputes at a recent meeting in China. Although an outline for the reports was agreed upon, key nations diverged on report delivery timing. An interim deal facilitates the initiation of the assessment process in 2025, with further discussions slated for later this year.
Governments have once again delayed a pivotal decision regarding the timing of key climate science assessments by the Intergovernmental Panel on Climate Change (IPCC). This is the third consecutive postponement, resulting from unresolved divisions at the recent IPCC meeting in Hangzhou, China. While officials managed to agree on the outline of three primary reports, a consensus on their delivery timeline remains elusive.
Most representatives supported a proposal from the IPCC’s administrative body to complete the scientific review process by August 2028. This timeline would allow the findings to be incorporated into the Global Stocktake under the Paris Agreement. Notably, support for this plan came from several nations, including those from Europe, Japan, Turkiye, and numerous small island states. However, it faced strong opposition from China, Saudi Arabia, and India, who expressed concerns about inclusivity in the process.
In the closing moments of the meeting, Chinese officials facilitated a preliminary agreement to commence the assessment process in 2025. Nonetheless, the deadline for the completion of reports will be further discussed at the next IPCC session, for which no date is currently established. IPCC Chair Jim Skea remarked on the progress achieved in outlining the scientific content despite a demanding agenda, emphasizing the importance of multilateral consensus.
The IPCC is currently engaged in its seventh assessment cycle (AR7), focusing on three reports that address the scientific basis of climate change, vulnerabilities of systems, and solutions to mitigate emissions. The sixth assessment previously played a significant role in guiding the first Global Stocktake in 2023, culminating in commitments to transition away from fossil fuels during COP28.
The role of China as the summit host was scrutinized for its leadership potential in global climate efforts, especially in the context of reduced US participation under previous administrations. Liu Zhenmin, China’s Special Envoy for Climate Change, underscored the need for multilateralism to advance global climate action. However, observers noted discrepancies between China’s public statements and its negotiating stance, indicating a priority for national concerns over global obligations.
Within the meeting, considerable time was devoted to discussions about the contents of the IPCC reports. Concerns arose from Diana Urge-Vorsatz, IPCC Vice-chair, regarding the removal of crucial scientific terms such as “Paris Agreement” and “fossil fuels.” She stressed that diluting these concepts undermines the effectiveness of international climate discussions.
Delegates also failed to agree on the outline for a methodology report addressing carbon dioxide removal technologies. A proposal led by Saudi Arabia to include marine geoengineering solutions was largely rejected due to concerns over the risks posed by such technologies. Many delegates argued that the scientific basis for these methods has yet to be sufficiently established.
The absence of US governmental representatives heavily impacted discussions, as previous travel restrictions imposed by the Trump administration curtailed their participation. Although the future of US involvement in the IPCC remains uncertain, ongoing discussions highlighted fears regarding the implications of such a withdrawal, particularly concerning the technical support the US previously provided to IPCC mitigation efforts.
In light of these challenges, it remains imperative for countries to collaboratively prioritize actionable commitments and timely decisions in the realm of climate science and policy.
In summary, the ongoing indecision surrounding the timing of critical IPCC climate science assessments underscores the rifts among nations regarding their commitment to climate action. While consensus on report outlines was achieved, the failure to finalize timelines suggests significant hurdles remain. The latest meeting in China illustrated both the need for broader inclusivity and the challenges posed by entrenched national interests, particularly in the context of global climate cooperation. Without resolute action, vulnerable nations may continue to face profound climate impacts.
