大国院士丨正因为难，所以必须要干——专访中国科学院院士焦念志

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]
