• Description:
  Understanding the in fluence of clouds on ampli fied Arctic surface warming remains an important unsolved research problem. Here, this cloud in fluence is directly quanti fied by disabling cloud radiative feedbacks or “cloud locking ”within a state ‐of‐the‐art and well ‐documented model. Through comparison of idealized greenhouse warming experiments with and without cloud locking, the in fluence of Arctic and global cloud feedbacks is assessed. Global cloud feedbacks increase both global and Arcticwarming by around 25%. In contrast, disabling Arctic cloud feedbacks has a negligible in fluence on both Arctic and global surface warming. Interestingly, the sum of noncloud radiative feedbacks does not change with either global or Arctic ‐only cloud locking. Notably, the in fluence of Arctic cloud feedbacks is likely
