A study published in Earth and Planetary Science Letters by scientists from Oregon State University, the Woods Hole Oceanographic Institution, University of British Columbia and U.S. Geological Survey and supported by the National Science Foundation investigates the ancient glaciers on Mauna Kea and the impact of the Atlantic meridional overturning circulation, or AMOC, in the North Atlantic Ocean. The study says that at the time it was both colder and there was huge increase of precipitation on Mauna Kea — triple that of the present — and there were more frequent cyclonic storm events hitting the Hawaiian Islands from the north. Mauna Kea had a glacial ice cap of about 70 square kilometers until 14,500 years ago.
