This presentation will provide an overview of recent CESM development activities emphasizing evolving Earth system capabilities, and new approaches for accelerating model development and deployment. Meeting the evolving needs from ESMs requires advances in both scientific realism and computational capability, including movement toward high-resolution (10–25 km) and ultra-high-resolution (km-scale) modeling configurations, more seamless prediction systems spanning subseasonal-to-seasonal (S2S), seasonal-to-decadal (S2D), and multidecadal climate projections, and exploiting AI through hybrid Machine Learning / Physics model versions and flexibly coupled emulators. The talk will discuss CESM progress in these realms and plans for the future.\n \nBiosketch:\nDavid Lawrence is a Senior Scientist at the NSF National Center for Atmospheric Research (NCAR).  His work centers on Earth system modeling, with an emphasis on terrestrial processes and their interactions with climate, including permafrost–carbon feedbacks, land–atmosphere coupling, hydrology, and land-use change impacts all aimed at improving the realism and predictive capability of Earth system models. He currently serves as Chief Scientist of the Community Earth System Model (CESM) and is leading the CESM team towards CESM3 and other developments.  He also played a central role in the development of multiple generations of the Community Land Model (CLM).  He is co-lead of the Land Use Model Intercomparison Project (LUMIP) and serves as the Model Development Liaison for the NSF Learning the Earth with Artificial intelligence and Physics (LEAP) project, an effort to exploit artificial intelligence to improve Earth System models.\n \nZoom Information\nEvent site: https://go.umd.edu/lawrence ( https://go.umd.edu/lawrence )\nZoom Webinar: https://go.umd.edu/essicseminarwebinars ( https://go.umd.edu/essicseminarwebinars )\nZoom Meeting ID: 971 2692 9944\nZoom password: essic\nUS Toll: 13017158592\nGlobal call-in numbers: https://umd.zoom.us/u/aMElEpvNu ( https://umd.zoom.us/u/aMElEpvNu )\n\nResources:\nSeminar schedule & archive: https://go.umd.edu/essicseminar ( https://go.umd.edu/essicseminar )\nSeminar Google calendar: https://go.umd.edu/essicseminarcalendar ( https://go.umd.edu/essicseminarcalendar )\nSeminar recordings on Youtube: https://www.youtube.com/user/ESSICUMD ( https://www.youtube.com/user/ESSICUMD )\nFor IT assistance: Cazzy Medley: cazzy@umd.edu\n URL:https://essic.umd.edu/events/david-lawrence-ncar/ ORGANIZER;CN=John Xun Yang:MAILTO:jxyang@umd.edu CATEGORIES:Fall 2026 LOCATION:UMD Zoom ATTACH;FMTTYPE=image/png:https://essic.umd.edu/wp-content/uploads/2026/08/david-lawrence.png END:VEVENT END:VCALENDAR
