## Antarctica's Ice Sheet
Antarctica holds enough ice to raise global sea level by 190 feet (58 meters).
## Coastal Vulnerability
1 billion people live in coastal areas; 100 million within 1 meter of sea level.
## Antarctica's Ice Future
Scientists disagree on whether Antarctica will gain or lose ice this century.
## New Study Finds
Antarctica's ice loss is locked in even with 1.5 degrees celsius warming limits.
## Why It's Hard to Predict
Greenhouse gas emissions determine ocean and air warming around Antarctica.
## Snowfall Doesn't Save
Warmer air holds more moisture, but extra snow won't offset ice loss.
## Machine Learning Model
Physics-informed machine learning predicts sea-level change faster than traditional models.
## 10 Million People at Risk
Antarctica could add 10 inches (25 centimeters) of sea-level rise by 2100.
## Key takeaway

Antarctica's ice loss is locked in for this century, extra snowfall won't save it, and coastal flooding risks rise for 10 million people.
