Methane at the Crossroads

Symposium at American Chemical Society National Meeting, 26-30 March 2023

Call for abstracts

Global atmospheric methane concentration was 720 ppb in pre-industrial times and is 1,900 ppb in 2022. For the past ten years, annual global emission of methane averaged 576 Tg CH4 with global CH4 sink average 556 Tg CH4; this mismatch reflects the observed imbalance in the atmosphere, i.e., the CH4 growth rate, and can be attributed to human activity. Atmospheric methane is dwarfed by carbon dioxide, which is responsible for the majority of global radiative heat trapping, but methane is a much more intense (infrared active) greenhouse gas. Further, the mean half-life of methane is about ten years, substantially less than carbon dioxide. Thus, if methane emission can be reduced (and/or sinks increased) we have a near-term opportunity to reduce the rate of global warming, per the objectives of the Intergovernmental Panel on Climate Change. Speakers will address methane in the atmosphere and scale-able efforts to address methane emission. This symposium is aligned with U.N. Sustainability Goals: 7) Affordable and Clean Energy; 9) Industry, Innovation and Infrastructure; 13) Climate Action, see: U.N. SDGs
