Abstract
A transect of climate sensitive tree ring‐width chronologies from coastal western North America provides a useful proxy index of North Pacific ocean‐atmosphere variability since 1600 AD. Here we use this high‐resolution record to identify intervals of an enhanced interdecadal climate signal in the North Pacific, and to assess the timing and magnitude of abrupt shifts in this system. In the context of this record, the step‐like climate shift that occurred in 1976–1977 is not a unique event, with similar events having occurred frequently during the past 400 years. Furthermore, most of the pre‐instrumental portion of this record is characterized by pronounced interdecadal variability, while the secular portion is more strongly interannual in nature. If the 1976–1977 event marks a return to this mode of variability there may be significant consequences for natural resources management in the North Pacific Sector.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
