Methane possible tipping points or surprises. Why is methane rising, how are sources and sinks changing, what is the risk from hydrates?

October 22, 2023 @ 12:00 am

Join AIMES, the Earth Commission, Future Earth, and the WCRP Safe Landing Climates Lighthouse Activity for a webinar on methane as part of a series that aims to advance the knowledge about tipping points, irreversibility, and abrupt changes in the Earth system.

All you need to know

This event is part of a series of online discussions that aims to advance knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system. It supports efforts to increase consistency in the treatment of tipping elements in the scientific community, develop a research agenda, and design joint experiments and ideas for a Tipping Element Model Intercomparison Project (TipMip).

This discussion series is a joint activity of the Analysis, Integration, and Modeling of the Earth System (AIMES) global research project of Future Earth, the Earth Commission Working Group 1 Earth and Human Systems Intercomparison Modelling Project (EHSMIP) under the Global Commons Alliance and the Safe Landing Climates Lighthouse Activity of World Climate Research Program (WCRP).

    The University of British Columbia

    Sara Knox, Assistant Professor at The University of British Columbia. Sara am interested in the impacts of climate variability and land-use change and management on biosphere-atmosphere exchange of water, energy, and trace gases. Her research and training is in micrometeorology, ecosystem ecology, and hydrology, and her work focuses on soil-plant-atmosphere interactions in a variety of climates and ecosystems.

    She combines micrometeorological measurements with remote sensing and modeling to understand the physical, biological and chemical processes that control trace gas fluxes between the land surface and the atmosphere across a range of spatial and temporal scales. Much of her work to date has focused on measuring and modeling water, energy and trace gas fluxes in restored and natural wetlands and agriculture, and her research has been used to help inform new and emerging climate policy in California.

    Prof. Euan Nisbet
    Royal Holloway University of London

    Euan Nisbet is Emeritus Professor (Earth Sciences), at the Department of Earth Sciences at the Royal Holloway University of London. His research into Modern and Glacial Atmospheres has mainly focussed on Methane in the modern air, including the role of methane in Arctic climate change, methane hydrates and their role in global warming, and the task of assessing present-day atmospheric methane burden. Current work includes major projects on Arctic and Tropical Atmospheric Methane budgets.

    Nisbet leads MOYA: the global methane budget. This is a UK NERC ‘Highlight’ consortium with 14 partner institutions that studies methane across the planet, with aircraft and ground field campaigns in African and South America, as well as monitoring greenhouse gases at a number of stations from the Arctic to the Antarctic and on a ship travelling from north to south in the Atlantic.
