Blue Carbon Sink Function Of Chinese Coastal Wetlands And Carbon Neutrality Strategy, Faming Wang, Jianwu Tang, Siyuan Ye, Jihua Liu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Coastal wetlands are the main body of the coastal "blue carbon (C)" ecosystem, and their "blue C" and ecosystem service function are important ocean-based climate change governance methods, which is a "nature-based solution". Chinese coastal wetlands are dominated by salt marshes, with little area of mangroves, while the area of unvegetated tidal flats is large. According to conservative estimation, the current C sequestration of coastal wetlands through sediment burial in China reaches to 0.97 Tg C·a-1, and would increase to 1.82-3.64 Tg C·a-1 at the end of this century. To achieve the commitment of "C neutrality" in 2060, China should …

Coral Reefs: Potential Blue Carbon Sinks For Climate Change Mitigation, Tuo Shi, Xinqing Zheng, Han Zhang, Qifang Wang, Xin Zhong
Bulletin of Chinese Academy of Sciences (Chinese Version)
Coral reefs are one of the most productive, and yet most vulnerable marine ecosystems. The global decline of coral reefs induced by climate change and human activities has already affected the processes of coral calcification and carbon cycling in the reef ecosystem, intensifying the long-standing CO2 "source-sink" debate over coral reefs. Despite the fact that coral calcification is accompanied by the release of CO2 to the atmosphere, the significance of coral reefs as a carbon sink cannot be ignored, given the complex biogeochemical processes in the reef ecosystem and the characteristic mixotrophic lifestyle of the reef-building corals. From the perspective …

Micro-organisms such as bacteria, archaea, and viruses are an immense invisible driving force behind the ocean carbon cycle and play a pivotal role in global climate change. Atmospheric CO2 is transformed into depositing organic components with the help of marine planktonic organisms which act as a biological pump (BP). The labile organic components are then transformed into recalcitrant organic carbon (RDOC) through the action of bacteria, archaea, and other organisms and viruses, which are called the microbial carbon pump (MCP). RDOC can be stored over thousands of years in the water column and the accompanying particulate organic matter can further …
