Antarctica is rising because of a phenomenon called post-glacial uplift. Huge volumes of ice have melted from the continent's glaciers, making it lighter. This means it is slowly rising. The melting glaciers are causing sea levels to rise. A geologist wrote: "Measurements show that the…Antarctic ice sheet is changing shape surprisingly quickly. The land uplift from reduced ice on the surface is happening in decades, rather than over thousands of years."

Researchers used 3D models to estimate rising sea levels. They could rise by 19.5 meters by 2500. A glaciologist wrote: "With nearly 700 million people living in coastal areas, and the potential cost of sea-level rise reaching trillions of dollars…understanding the domino effect of Antarctic ice melt is crucial." She wrote about "the climate injustice toward nations whose emissions are low, while their…vulnerability to sea-level rise is high."
