From Antarctica to Brussels, hunting climate clues in old ice

In a small, refrigerated room at a Brussels university, parka-wearing scientists chop up Antarctic ice cores tens of thousands of years old in search of clues to our planet’s changing climate. “We want to know a lot about the climates of the past because we can use it as an analogy for what can happen in the future,” said Harry Zekollari, a glaciologist at Vrije Universiteit Brussel (VUB).
