The US Department of Energy's (DOE) Office of Science initiated the Energy Exascale Earth System Model (E3SM) development in 2014. The project was motivated by the need for a climate and Earth system model that would support DOE’s energy mission and meet the requirement to run on the next-generation Exascale computing systems. To provide actionable information on the climate impacts on energy and other sectors and how climate change may influence the sustainable energy futures, we developed a three-pronged strategy focusing on high-resolution modeling to improve simulations of extreme events that impact energy production and use, modeling the coupled human-Earth system to project future outcomes, and large ensemble modeling to quantify uncertainty. In this presentation, I will briefly introduce various E3SM capabilities, including the recently released E3SM version 3 and the global cloud resolving model (SCREAM), modeling experiments with output broadly shared with the community, and examples of science applications of E3SM towards understanding Earth system predictability and the potential impacts of climate change on coastal and urban populations.
