Ocean Circulation Continues for Centuries Even After Key AMOC Engine Shuts Down

The Ocean Circulation That Persists Even After a Key AMOC Component Fails, by Nathaniel Scharping (Eos, American Geophysical Union, published 13 October 2026), is a research spotlight summarizing a study in AGU Advances.

Community Earth System Model 2 (CESM2) is a fully coupled, open- source global Earth system model developed collaboratively by the National Center for Atmospheric Research (NCAR) and the broader research community. It simulates Earth’s past, present, and future climate and Earth-system states and served as a major contributor to the Coupled Model Intercomparison Project Phase 6 (CMIP6).

Model output from preindustrial control, historical, and other experiments is publicly available (e.g., via ESGF). CESM2 has been applied in diverse studies, including AMOC behavior under CO₂ quadrupling, ice-sheet coupling, sub seasonal prediction, and chemistry- climate interactions.
