How quickly will Antarctica鈥檚 massive Thwaites Glacier melt, and what will that mean for global sea levels and coastal cities? Scientists spent several weeks aboard the research ship Nathaniel B Palmer, studying Thwaites as part of a five-year, international effort to try to answer those pressing questions. Our reporter Carolyn Beeler takes us onboard for a deep dive into the science and the stakes for our future.
