Abstract

A conservative evaluation of glacial-geologic, sea level, and benthic δ O 18 data indicates that ice volume at 35,000 yr B.P. was approximately 50% of that extant at the Last Glacial Maximum, LGM, (20,000 yr B.P.); that is, it doubled in about 15,000 yr. On the basis of literature for the North Atlantic and a sea-surface temperature (SST) data compilation, it appears that this rapid growth may have been forced by low-to-mid-latitude SST warming in both the Atlantic and Pacific Oceans, with attendant increased moisture transport to high latitudes. The SST ice-sheet growth notion also explains the apparent synchroneity of late Wisconsinan mountain glaciation in both hemispheres
