Scientists can now forecast Antarctic ice loss through mid-century, providing governments with a critical window to prepare for rising sea levels. After this period, the rapid acceleration of unstable ice retreat could make future predictions much more challenging.

Historically, Antarctica has been a significant contributor to global sea level rise due to its vast ice sheets. The ability to predict ice loss accurately offers policymakers time to implement protective measures and adapt infrastructure accordingly.

However, beyond mid-century, the unpredictability of ice sheet behavior could lead to sudden increases in sea levels, posing severe risks to coastal communities worldwide.
