The planet’s warmer temperatures then matched what many scientists predict we may experience in the next 80 to 100 years, making it an ideal era of study in forecasting the effects of a changing climate on our future. In such a colder time, when large ice sheets covered much of the Earth, dry, whirling winds were more than twice as strong as they are today.ĭ’Andrea and his colleagues have come to Hawaii to look for fossilized coral from a different span, the last interglacial period, which lasted from around 125,000 to 110,000 years ago. “Just imagine what these winds were like during a glacial period,” he says. On land, a team of researchers trod through sun-scorched dunes like ducklings in a row, tucking themselves between geological nooks and crannies along the shoreline-searching for answers from a distant past.īilly D’Andrea, a paleoclimatologist for Columbia University’s Lamont-Doherty Earth Observatory, scrunches his nose as he peers up at the sun beneath his wide-brimmed hat.
