Core Insights - The twelfth International Ecological Society Wetland Conference and the twentieth annual meeting of the European chapter of the International Wetland Scientists Association took place in Tartu, Estonia, where a significant initiative on coastal wetland carbon sinks was presented by a team led by Chinese Academy of Sciences academician Jiao Nianzhi [1] Group 1: Initiative Overview - The initiative titled "Land-Sea Interaction - Coastal Wetland Carbon Sink Initiative under the United Nations Ocean Decade ONCE Plan" outlines five major action frameworks aimed at guiding global research and collaboration on coastal wetland carbon sinks [2] - The five action frameworks include promoting scientific cooperation, establishing a global alliance, conducting technology sharing, integrating local wisdom, and implementing demonstration projects [2] Group 2: Conference Highlights - The session on "Coastal Wetland Negative Carbon Emissions: Mechanisms, Practices, and Challenges" was co-chaired by Jiao Nianzhi and researcher Ye Siyuan, focusing on climate change, sea level rise, and nutrient loading, discussing strategies to enhance the carbon sink function of coastal wetlands [3] - Experts from various fields emphasized the importance of coastal wetlands as key "blue carbon sinks" and identified challenges in their protection, advocating for interdisciplinary research to overcome technological bottlenecks [3] Group 3: ONCE Plan Background - The ONCE Plan, initiated by Jiao Nianzhi in 2019, aims to explore ocean negative emission mechanisms through collaboration among multiple national research institutions and establish international standards to address climate change [4] - As of 2024, the ONCE Plan has attracted participation from 33 countries and 79 research institutions, enhancing China's international influence and technological leadership in marine negative emissions and ecological protection [4]

Core Viewpoint - The "Coastal Wetland Carbon Sink Initiative" was presented at the 12th International Ecological Society Wetland Conference, highlighting the importance of coastal wetlands in carbon sequestration and the need for global collaboration in research and technology sharing [1][2]. Group 1: Initiative Overview - The initiative proposes five action frameworks to guide global research and collaboration on coastal wetland carbon sinks, including promoting scientific cooperation, establishing a global alliance, sharing technology, integrating local wisdom, and implementing demonstration projects [2]. - A total of 32 scientists from 15 countries signed a support document for the initiative, marking a significant step in building a global collaboration system for coastal wetland carbon sink research [2]. Group 2: Conference Insights - The conference focused on key issues such as climate change, sea level rise, and nutrient loading, discussing strategies to enhance the carbon sink functions of coastal wetlands [3]. - Experts emphasized the challenges faced in protecting coastal wetlands as critical "blue carbon sinks" and the need to overcome technological bottlenecks in land-sea interactions [3]. Group 3: ONCE Plan Background - The ONCE Plan, initiated by Academician Jiao Nianzhi in 2019, aims to explore ocean negative emission mechanisms through international collaboration and has attracted participation from 33 countries and 79 research institutions by 2024 [4]. - The plan is integrated into the UNESCO "Decade of Ocean Science for Sustainable Development" action plan, enhancing China's international influence in marine negative emissions and ecological protection [4].

Core Insights - The article discusses the urgent challenge of global warming and highlights the ocean's role as a significant carbon sink, capable of absorbing vast amounts of carbon dioxide [2][3] - A Chinese scientist, Jiao Nianzhi, has proposed an innovative mechanism called the "microbial carbon pump" to enhance the ocean's ability to sequester carbon [2][5] - The "International Marine Negative Emission Science Plan" led by Jiao aims to provide a global solution for carbon management based on Chinese practices [8] Group 1: Ocean's Carbon Absorption Capacity - The ocean absorbs approximately 2 billion tons of carbon dioxide annually, which is equivalent to the emissions from about 800 million gasoline cars [3] - The ocean's carbon storage capacity is about 50 times that of the atmosphere and 20 times that of land [3] Group 2: Microbial Carbon Pump Theory - Jiao Nianzhi's "microbial carbon pump" theory suggests that microscopic marine organisms can be utilized to enhance carbon absorption [5][6] - The process involves organic carbon particles being encapsulated, preventing them from being consumed by bacteria, thus allowing them to settle on the ocean floor for long-term storage [6] Group 3: International Collaboration and Research - The "International Marine Negative Emission Science Plan" has garnered support from 79 institutions across 33 countries, focusing on collaborative research to explore marine carbon sequestration mechanisms [8] - Jiao emphasizes the importance of sharing knowledge and promoting scientific collaboration on a global scale [8]
