A scientific expedition to Antarctica is allowing researchers to get a rare view of the Thwaites Glacier, which juts out of the West Antarctic ice sheet.
The view is thrilling and other-worldly. But the real-world implications of the research could be devastating for the planet.
The Florida-sized glacier is melting and it has the potential, by itself, to cause sea levels to rise two feet globally. A new study found near 25 percent of the ice sheet is unstable.
Carolyn Beeler, an environment reporter for "The World," spent more than a month on board the research ship Nathaniel B. Palmer traveling to Antarctica earlier this year.
She joins Midday Edition on Monday to talk about what researchers are trying to understand about the melting glacier.
