Scientists studying the Thwaites Glacier in West Antarctica, known as the "Doomsday Glacier," have revealed alarming trends that could lead to significant sea-level rise in the coming centuries. The International Thwaites Glacier Collaboration (ITGC), a joint research initiative between the U.K. and the U.S., has been monitoring the glacier, which is roughly the size of Florida, since 2018.
Recent findings indicate that Thwaites has been retreating for over 80 years, with a marked acceleration in the last 30 years. Rob Larter, science coordinator of ITGC, stated, "Our findings indicate it is set to retreat further and faster." If the glacier collapses, millions in low-lying areas, such as Bangladesh and Pacific Islands, could face catastrophic sea-level rise, with major cities like New York and London also at risk.
While some researchers believe Thwaites may remain stable for the next few decades, the long-term outlook remains dire. The ITGC warns that by the 23rd century, Thwaites and much of the West Antarctic Ice Sheet could be entirely lost, potentially raising global sea levels by over 10 feet.
Currently, sea levels are rising by 0.13 inches per year, with the Thwaites region contributing to 8 percent of this increase. Advanced technologies are being used to study the glacier, yet uncertainties about its future remain. Ted Scambos, U.S. science coordinator of the ITGC, emphasized that while climate action can mitigate some effects, the results will take time to manifest.
As scientists continue to monitor this critical region, the urgency for global climate action becomes increasingly clear. Understanding and addressing these changes is essential for future generations to cope with the impending impacts of rising seas.
