The westerlies in the Northern Hemisphere, which increased

precipitation and temperature anomalies, especially over Europe.
Evidence
from glacial advance / retreat (e.g. the evidence
from tropical Andean glaciers you cite above) is often difficult to interpret, because glacial mass balance represents in general a subtle competition between the influences of ablation (determined by
changes in temperature thresholds reached) and accumulation (determined by
changes in humidity and
precipitation).
The study concludes that the growth of the Mauna Kea glacier caused by the AMOC current
