Antarctica's Doomsday Glacier Is Making Headlines Again - And It's Alarming

Know what to watch, what to have at home, and when it is time to leave: https://thefieldreportstore.com THE AMUNDSEN SEA, September 21, 2026 — Fresh satellite radar from the past week shows the last floating ice shelf bracing West Antarctica's Thwaites Glacier — the so-called Doomsday Glacier — fracturing crack by crack, with the damage now driving inward into the eastern section that had been holding. The Thwaites Eastern Ice Shelf's flow has tripled since 2020, and the British Antarctic Survey says it's very likely to break up this year — so likely the agency pre-wrote the shelf's "obituary." Thwaites alone holds enough ice to raise global seas by about 65 cm, and it braces a wider ice sheet worth roughly 3 meters more. Alongside the radar came a louder claim: that a Pacific tidal wave could be coming, that a global alert should be raised to its highest setting. The real science of what a breaking glacier can and cannot do is stranger than either the panic or the shrug — and it turns on a single measurement scientists cannot see yet.
