“瓦里关曲线”见证全球气候治理的中国担当

Core Viewpoint - The Wari Pass Global Atmospheric Background Station, located at an altitude of 3,816 meters on the Tibetan Plateau, has been operational for over 30 years, providing crucial data for global climate change research and is now protected by local regulations effective February 1, 2026 [3][10]. Group 1: Scientific Value and Observations - The Wari Pass Station has accumulated long-term atmospheric CO2 concentration data, creating the "Wari Pass Curve," which aligns closely with observations from the Mauna Loa Observatory in Hawaii, indicating a consistent rise in greenhouse gas concentrations globally [4][7]. - The station's establishment in the 1990s filled a critical gap in the global atmospheric observation network, particularly for inland areas, and has since become a key site for greenhouse gas monitoring in China [5][7]. Group 2: Environmental Protection and Sustainability - To ensure the accuracy and sustainability of observations, Qinghai Province has implemented protective measures around the Wari Pass Station, including the establishment of an 80-acre protection zone to control potential pollution sources [10]. - The new regulations will integrate meteorological environment protection into land use planning, reinforcing the commitment to ecological preservation while supporting the station's operations [10]. Group 3: Contribution to Climate Governance - The Wari Pass Station is part of a broader national network of atmospheric observation stations in China, which includes one global background station and over 120 greenhouse gas monitoring stations, contributing to the "China Greenhouse Gas Bulletin" [13]. - China's carbon emissions increased by approximately 0.6% in 2024, a slower growth rate compared to the global average of 0.8%, indicating progress in managing emissions [13]. - The station's data is vital for assessing China's climate action effectiveness and supports international climate governance efforts, with China actively participating in global climate discussions and initiatives [19].
