报告内容📱👩🏭:
Wetlands are the largest natural methane (CH4) emitters and account for one-third of the total combined natural and anthropogenic sources in the global methane budget. The positive response of wetland methane emissions to climate change is an important yet uncertain Earth-system feedback that amplifies atmospheric CH4 concentrations. In this presentation, Dr. Zhen Zhang will discuss the latest wetland methane estimates based on wetland models, atmospheric measurements, and ground observations from a few recent projects, providing insights into wetland ecosystem responses to climate variability and feedback associated with these responses.
