A massive Antarctic glacier, dubbed the “Doomsday Glacier,” is melting at an accelerating rate and could be approaching irreversible collapse, international researchers are reporting. The Thwaites Glacier, holding enough ice to raise global sea levels by over two feet, has seen rapid retreat in the past 30 years.
Scientists from the International Thwaites Glacier Collaboration used ice-breaking ships and underwater robots to study the glacier up close since 2018. Their findings reveal warm ocean water funneling through deep cracks in the ice, causing unexpected melting patterns. While computer modeling suggests catastrophic cliff collapse is less likely than feared, researchers project Thwaites and the Antarctic Ice Sheet could disintegrate within 200 years. This collapse could ultimately lead to 10 feet of sea level rise, devastating coastal communities worldwide.
