世界领先的气候变化权威机构成员会议于周五结束，未就发布其下一份关于变暖星球最新科学的评估报告的时间表达成一致，四位熟悉情况的消息人士称。
The meeting of the members of the world's leading authority on climate change ended on Friday without an agreement on a timeline to publish its next review of the latest science on the warming planet, four sources familiar with the matter said.
本周，政府间气候变化专门委员会（IPCC）195个成员国的代表在埃塞俄比亚首都亚的斯亚贝巴举行会议，许多人认为这是在2028年11月联合国气候谈判之前就报告发布日期达成一致的最后机会，届时各国政府将评估2015年巴黎协定所设定目标的进展。
The meeting of representatives to the Intergovernmental Panel on Climate Change from its 195 member states in Ethiopia's capital, Addis Ababa, this week was seen by many as the last chance to agree publication dates before UN climate talks in November 2028, when governments are due to assess progress toward goals set in the 2015 Paris agreement.
这一持续近三年的僵局可能导致各国在关键问题上缺乏共识的情况下决定下一阶段的行动，这些问题包括全球变暖在多大程度上可能是可逆的。IPCC未立即回应置评请求。
The impasse, which has lasted nearly three years, could leave countries to decide the next phase of action without consensus on critical issues, including the extent to which some global warming might be reversible. The IPCC did not immediately respond to a request seeking comment.
该争议反映了富裕工业化国家、主要新兴经济体和较贫穷国家在应对气温上升方面的深刻分歧，以及应由不同国家承担多少责任的分歧。
The dispute reflects deep rifts among wealthy industrialized nations, major emerging economies and poorer nations over how to respond to warming temperatures and how much of that burden should be shouldered by different countries.
有30个国家组成的联盟对IPCC的报告可能无法及时准备好用于2028年气候谈判表示担忧，该联盟包括欧洲、拉丁美洲和小岛屿国家，他们主张立即采取行动。
The possibility that the IPCC's reports might not be ready in time for the 2028 climate talks has alarmed a coalition of 30 countries, including European, Latin American and small-island states pushing for immediate action.
然而，印度、肯尼亚、沙特阿拉伯、俄罗斯和中国等国家正在争取更多时间来准备IPCC的下一份报告，以确保来自资源较少国家的科学家能够作出有意义的贡献。
However, countries including India, Kenya, Saudi Arabia, Russia and China are pressing for more time to prepare the IPCC's next reports to ensure scientists from less-resourced countries can make meaningful contributions.
IPCC对世界现有气候变化知识的评估报告在政府间具有重要影响，因为这些报告由数百名国际专家撰写，并得到每个成员国的批准。
The IPCC's reviews of the world's existing knowledge on climate change carry weight with governments because they are written by hundreds of international experts and approved by every member state.
这些报告也被政府用于制定应对气候变化的计划，并曾被引用在国际法院的裁决中。
Its reports are also used by governments to plan their responses to climate change and have been cited in international court rulings.
联合国环境规划署一再表示，全球限制升温的努力远远不足，需要更深层次的减排，以避免更极端的天气和气候相关灾害。
The UN Environment Programme has said repeatedly that global efforts to limit warming are falling short and that deeper emissions cuts are needed to avoid more extreme weather and climate-related disasters.
