One hundred and forty meters of Greenland ice are chilling 3,000 miles from home in a facility in Denver, Colorado, where scientists have been chipping away at a revelation about our planet’s past.

Over the past two millennia, ice caps along the frigid slopes of Greenland’s west coast sometimes expanded in response to a warming climate, according to a new study of ice cores published in Nature Geoscience.

According to the researchers, in past centuries these ice caps would expand due to...
