evidence: Community-systemic issues are systematic errors shared by multiple diverse climate models (e.g., across CMIP ESMs) and are typically due to a community-wide issue related to the absence, or manner of treatment, of one or more physical processes. [...] Similarly, OMIP-like ocean-only experiments that systematically change out only the observed wind stress for the CanESM5 wind stress are not definitive: the specification of other surface forcing from observations (e.g., surface air temperature and SSS) carries with it the imprint of observed sea-ice distributions, and the lack of coupled feedbacks suppresses the true effect that wind stress bias would have in the coupled model.
