Improved ice sheet modeling techniques in this study indicate that current rates of ice loss from the West Antarctic Ice Sheet show a strong possibility of future collapse in the region, even with no further warming. If ocean temperatures simply remain at present-day levels for several centuries, the models project that two of the largest glaciers in West Antarctica, Thwaites and Pine Island, will collapse, resulting in global sea-level rise of at least 1.2 meters from these two glaciers alone. Simulations of immediate cooling temperatures down to pre-industrial slowed, but in most cases could not prevent the collapse. This research highlights the potential for significant sea-level rise even without additional warming, emphasizing the long-term consequences communities could face under current climate conditions.
