John H. Mercer (1922-1987) was a British glaciologist known for his research on Antarctic ice streams and the West Antarctic ice sheet's vulnerability to melting. He postulated that climatic warming could cause significant ice sheet retreat, especially during the last interglacial. Mercer's findings were significant enough to coin the term 'John Mercer effect,' highlighting potential modern impacts. Educated in England and Canada, he worked at several institutions, ultimately becoming a senior research scientist at Ohio State University until his death.
