Core Viewpoint - The Trump administration's decision to revoke the 2009 greenhouse gas endangerment finding marks a significant reversal in U.S. federal climate policy, raising concerns in scientific, legal, and public health domains, with potential implications for judicial, energy sectors, and international climate governance [1][3]. Regulatory Changes - The U.S. Environmental Protection Agency (EPA) described the decision as "the largest single rollback of regulation in U.S. history," claiming it would save taxpayers over $1.3 trillion by alleviating regulatory burdens that exceeded $1 trillion [2]. - The EPA's rationale is that the Clean Air Act was originally intended to regulate criteria air pollutants and toxic substances, not greenhouse gases, suggesting that previous interpretations expanded regulatory authority unnecessarily [2]. Legal and Scientific Controversy - The 2009 finding, established during the Obama administration, recognized six greenhouse gases as threats to public health, forming the legal basis for various emission control measures [3]. - Critics argue that revoking this finding undermines scientific consensus on climate change and contradicts global climate governance trends, potentially complicating future regulatory efforts [3][4]. Broader Implications - The decision is part of a broader trend, with the Trump administration reportedly taking over 300 actions to roll back climate-related policies, which may weaken the U.S.'s credibility in global climate governance [6]. - Recent actions include the revocation of fishing bans in marine protected areas and directives to support coal-fired power plants, which could lead to increased operational costs for electricity users [6][7]. Economic Impact - The economic losses from climate-related disasters in 2025 alone are estimated at $115 billion, indicating a significant financial burden associated with climate inaction [7]. - The interplay between energy security, economic costs, and climate risks will continue to shape the future of U.S. climate governance [7].

Core Insights - The article highlights the significance of the Wari Pass Atmospheric Background Station in Qinghai Province, which is the only global atmospheric background station in China and one of the highest in the world, operational since September 17, 1994 [2] Group 1 - The Wari Pass Station is located at an altitude of 3,816 meters and has been continuously monitoring atmospheric conditions for nearly 32 years [2] - The station's data contributes to the "Wari Pass Curve," which reflects the monthly average concentration of carbon dioxide in the atmosphere, playing a crucial role in China's climate change response and global climate governance [2] - The dedicated personnel at the station exemplify commitment and responsibility in high-altitude meteorological observation, ensuring accurate data collection for environmental monitoring [2]

转自：法治日报 □ 本报记者 赵阳 当地时间1月27日，美国退出《巴黎协定》的程序正式生效，这个历史累计碳排放占全 球20%的国家，成为唯一一个两次退出该协定的国度。从2017年在特朗普首个任期内首次"退群"，到 2021年拜登政府时期仓促重返，再到2025年再度官宣退出，美国围绕《巴黎协定》上演的退出"戏码"， 早已超越气候政策本身的争议，沦为一场暴露"美国优先"霸权逻辑的政治闹剧，其"合则用、不合则 弃"的单边行径，正给全球气候治理带来难以愈合的创伤。 美国的"退群"决定，从来不是基于科学判断 的理性选择，而是国内政治利益算计的必然结果。2025年特朗普政府重启"退群"程序，背后清晰可见共 和党与化石能源行业的利益绑定——2024年总统选举中，化石能源巨头为特朗普阵营注入巨额政治献 金，而且传统能源行业的数百万从业者构成了其核心选票基本盘。这种"选票与金主绑定"的政治生态， 让美国政府毫不犹豫地将全人类的气候福祉让位于短期政治利益。 更值得警惕的是，美国的"退群"行 为具有明确的选择性标准。在特朗普扬言退出的66个国际组织及协定中，31个隶属于联合国框架，且多 集中在公共卫生、气候治理等"不能体现硬实力" ...

Core Viewpoint - The Wari Pass Global Atmospheric Background Station in Qinghai Province plays a crucial role in monitoring greenhouse gas concentrations and contributes significantly to global climate change research through its long-term observational data [3][4][10]. Group 1: Importance of Wari Pass Station - The Wari Pass Station has been operational for over 30 years, providing continuous and high-precision observations of atmospheric carbon dioxide concentrations, which are critical for understanding global climate trends [3][4]. - The data from Wari Pass, known as the "Wari Pass Curve," aligns closely with observations from the Mauna Loa Observatory in Hawaii, demonstrating a consistent increase in greenhouse gas concentrations globally [3][4]. - The establishment of the Wari Pass Station filled a significant observational gap for continental atmospheric monitoring, contributing to the global atmospheric observation network [3][4]. Group 2: Environmental Protection Measures - To ensure the accuracy and reliability of observations, Qinghai has implemented protective measures around the Wari Pass Station, including the establishment of an 80-acre protection zone to control potential pollution sources [9]. - New regulations effective from February 1, 2026, will provide a legal framework for the protection of the Wari Pass Station, integrating environmental protection into land use planning [9]. - The station's operational environment is maintained with strict protocols to minimize human interference, which is essential for the continuity and comparability of the data collected [7][9]. Group 3: Contribution to Climate Change Mitigation - The data generated by the Wari Pass Station is vital for assessing China's efforts in combating climate change, with the 2024 report indicating a 0.6% increase in human carbon emissions, lower than the global average of 0.8% [11]. - The station serves as a foundation for a national network of atmospheric observation stations, enhancing China's capacity to contribute to global climate governance [10]. - China's commitment to improving its technological support for climate change initiatives is evident, as it aims to lead in global climate governance and sustainable development [12][13].

美国总统特朗普在2025年1月20日就任当天签署行政令，宣布美国将退出《巴黎协定》。联合国在2025年1月28日宣布，已收到美国退出旨在应对气候变化的 《巴黎协定》的通知，退约将在2026年1月27日起正式生效。 国际人士表示，美国再次退出《巴黎协定》是对多边主义的又一次破坏。美国放弃气候承诺，将造成严重后果。 法国前总理 法比尤斯：美国总统曾公开宣称"气候变暖不存在"，这与目前全部科学共识完全相悖。在这种错误论调影响下，美国重新大力发展石油和天然 气生产，甚至成为唯一一个两次退出《巴黎协定》的国家。考虑到美国在国际体系中的重要地位，这种行为对全球气候治理，带来了非常消极、负面的影 响，尤其令人担忧的是多边主义本身正受到攻击。我们看到全球多地爆发战争，一些国家公然宣称，规则和国际法无关紧要，力量和单边行动才是关键。 德国绿党创始人之一、前欧洲议会议员弗兰克·施瓦尔巴-霍特表示，美国放弃应对气候变化的承诺是一场灾难，尤其糟糕的是，会对其他国家做出错误示 范。 德国民众也表示，美国的这一行为可能对地球环境造成灾难性的后果。 柏林居民 芭芭拉·费舍尔：美国是二氧化碳和甲烷等温室气体的主要排放国之一，而且美国的行动对 ...
