The study identifies significant risks associated with Antarctic ice loss, including the potential inundation of one-quarter of Australian residential properties and the displacement of millions globally. Pacific Island nations are particularly vulnerable, with rising sea levels threatening infrastructure, land use, and community stability. While the next three decades offer a predictable trajectory for sea level rise, the long-term risks remain uncertain, with the possibility of rapid and irreversible ice loss. This uncertainty underscores the urgency for governments to act within the current window of predictability to mitigate future humanitarian and economic challenges.
