IPCC面临报告时间表的空前僵局，关键2028年联合国气候谈判临近。
政府间气候变化专门委员会（IPCC）成员国在就其下一份评估报告的发布时间表进行了近三年的谈判后仍然陷入僵局。
IPCC Faces Unprecedented Deadlock Over Report Timelines Ahead of Crucial 2028 UN Climate Talks Member states of the Intergovernmental Panel on Climate Change (IPCC) remain deadlocked after nearly three years of negotiations over the publication timeline for their next assessment reports.
超过30个国家的联盟，包括欧洲和小岛屿国家，要求在2028年11月联合国气候峰会之前发布所有三份主要报告，以制定国家减排目标。
A coalition of more than 30 nations, including European and small-island states, demands the release of all three major reports before the November 2028 United Nations climate summit to inform national emission targets.
相反，印度、中国、沙特阿拉伯、肯尼亚和俄罗斯等国家主张将两份报告推迟至2029年，认为压缩的时间表会损害包容性并增加发展中国家研究人员的负担。
Conversely, countries including India, China, Saudi Arabia, Kenya, and Russia argue for pushing two reports to 2029, asserting that a compressed schedule compromises inclusivity and burdens researchers from developing nations.
此争端发生在美国于2026年1月退出IPCC之后，并在2026年10月12日埃塞俄比亚亚的斯亚贝巴即将举行的关键全体会议之前。
The dispute precedes a crucial plenary meeting in Addis Ababa on October 12, 2026, following the United States' withdrawal from the IPCC in January 2026.
