How much of Antarctica is covered by ice?
Answer
98%
Approximately 98% of Antarctica is covered by ice, containing roughly 90% of Earth's ice and 70% of its fresh water reserves. The Antarctic ice sheet averages 2 kilometers in thickness and has persisted for millions of years, with ice cores providing scientists with climate records spanning 800,000 years. This massive ice sheet plays a critical role in global climate regulation and sea level, with warming potentially causing catastrophic sea level rise.
