Title:Wetland Methane Feedback over the Last Decades: A Bottom-Up Perspective

Moderator:Professor Geng Haopeng, College of Earth and Environmental Sciences, Lanzhou University

Time:January 16, 2024 (Tuesday) from 15:00 - 17:00

Venue:Room 502, Qilian Hall, Chengguan Campus, Lanzhou University

Summary of report:

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.

Expert Profile:

Zhang Zhen, a researcher at Tibetan Plateau Research Institute, Chinese Academy of Sciences, a selected researcher of "Overseas Excellent Youth Program" of the Foundation Committee. He has worked as a research scientist at WSL Institute, University of Maryland, and NASA Goddard Space Flight Center. He has long been engaged in mechanistic studies of biogeochemical cycling in terrestrial ecosystems, quantitative estimation and driving mechanisms relating to methane emissions from wetlands and methane cycling. He has published more than 60 papers, some of which have been published in Nature, Nature Climate Change, Science Advances, National Science Reviews, Nature Communications, PNAS and other journals, and several papers have been listed as highly cited articles. Some of his papers have been cited in several authoritative literature, including the Sixth Report of the IPCC and the Second National Assessment of Climate Change (NACCC). Currently, he is mainly involved in the Global Carbon Project Methan, and leads the simulation experiment of terrestrial wetland model ensemble.
