Scientists issue warning on 'unstoppable' phenomenon that could have global impact: 'Catastrophic consequences'
by Matthew Swigonski, 9/3/2025
"According to a recent study, a team of researchers has determined that the West Antarctic Ice Sheet is at an increased risk of completely collapsing due to continually high levels of atmospheric carbon dioxide. Even with progressive shifts in dirty fuel usage, realistic reductions in CO2 may still not be enough to prevent more abrupt changes."

World’s biggest iceberg, A23a, has broken up
The A23a iceberg has been closely tracked by scientists ever since it calved from the Filchner-Ronne ice shelf in Antarctica in 1986.

" 'The world’s largest iceberg is 'rapidly breaking up' into several large 'very large chunks,' scientists from the British Antarctic Survey (BAS) have said.
"Previously weighing nearly a trillion metric tonnes (1.1 trillion tons) and spanning an area of 3,672 square kilometers (1,418 square miles) — slightly bigger than Rhode Island — the A23a iceberg has been closely tracked by scientists ever since it calved from the Filchner-Ronne ice shelf in Antarctica in 1986.

Scientists looked deep beneath the #DoomsdayGlacier. What they found spells potential disaster for the planet
By Laura Paddison, September 20, 2024
"Scientists using ice-breaking ships and underwater robots have found the #ThwaitesGlacier in Antarctica is melting at an accelerating rate and could be on an irreversible path to collapse, spelling catastrophe for global sea level rise.
"Since 2018, a team of scientists forming the International Thwaites Glacier Collaboration, has been studying Thwaites — often dubbed the '#DoomsdayGlacier' — up close to better understand how and when it might collapse.
"Their findings, set out across a collection of studies, provide the clearest picture yet of this complex, ever-changing glacier. The outlook is 'grim,' the scientists said in a report published Thursday, revealing the key conclusions of their six years of research.
"They found rapid ice loss is set to speed up this century. Thwaites’ retreat has accelerated considerably over the past 30 years, said Rob Larter, a marine geophysicist at the British Antarctic Survey and part of the ITGC team. 'Our findings indicate it is set to retreat further and faster,' he said.
"The scientists project Thwaites and the Antarctic Ice Sheet could collapse within 200 years, which would have devastating consequences.
"Thwaites holds enough water to increase sea levels by more than 2 feet. But because it also acts like a cork, holding back the vast Antarctic ice sheet, its collapse could ultimately lead to around 10 feet of #SeaLevelRise, devastating coastal communities from Miami and London to Bangladesh and the Pacific Islands.
"Scientists have long known Florida-sized Thwaites was vulnerable, in part because of its geography. The land on which it sits slopes downwards, meaning as it melts, more ice is exposed to relatively warm ocean water."
