B44D:
The Global Methane Cycle II


Submit an Abstract to this Session


Session ID#: 59942

Session Description:
Methane is a potent greenhouse gas with a shorter atmospheric lifetime than CO2 but a stronger warming potential molecule for molecule.  Concentrations of CH4 continue to increase, making it a critical component of pathways to mitigate climate change. This session highlights bottom-up and top-down integration of measurements and model simulations of methane sources and sinks. Examples of relevant topics include wetland and freshwater emissions, sources from the agriculture and energy sectors, and inverse modeling and atmospheric isotopes. The session also invites research on inter-annual and decadal scale trends and variability. The research presented will contribute to an updated global methane budget being developed under the umbrella of the Global Carbon Project and to IPCC AR6 carbon budgets.
