Natural wetlands emit approximately 30% of global methane (CH4) emissions. The water‐logged soils in wetlands are ideal for producing methane (an important greenhouse gas), and the patterns and intensity of these emissions are likely to change as the planet warms. Our estimates of global wetland CH4 emissions and the factors that drive them are uncertain, in part due to the scarcity of high‐resolution CH4 emission datasets.
As part of a USGS Powell Center synthesis group, we compiled eddy flux tower measurements of CH4 emissions from 82 sites across the globe. This unprecedented CH4 dataset allows us to tackle important questions about what drives methane emissions, how we can improve biogeochemical models of CH4 emissions, and how wetlands may respond to climate change. Prof. Jackson will discuss the many on‐going projects in this USGS Powell group, including what we have learned so far and what big questions remain.
Happy hour to follow at Avogadro's Number.
