Researchers drill into Antarctica's 'Doomsday Glacier'

Season 2026 Episode 25 | 7m 04s

An expedition to Antarctica has brought scientists and researchers to the widest glacier on Earth. The Thwaites Glacier is nicknamed the Doomsday Glacier because of its potential impact on sea levels if ice continues to melt. Miles O'Brien reports on the work to drill into the ice to record temperatures and understand the impact of climate change. It's part of our series, Tipping Point.
