Antarctica's Ice Loss Locked In
Antarctica will lose more ice than it gains this century even with 1.5C warming limits.
In brief
Antarctica will lose more ice than it gains this century even with 1.5C warming limits. 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. Originally reported by The Conversation.
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.
What it means
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.
