Voyage to Antarctica seeks to learn why a glacier is melting

Season 2026 Episode 17 | 12m 00s

Scientists are worried about the melting of Antarctica's ice sheets and what it could mean for sea levels. There's a two-month-long journey underway to conduct research that will better explain what's happening. But it's a journey that provides no guarantees that researchers will even be able to get the data they want. Science correspondent Miles O'Brien reports for our series, Tipping Point.
