Do Ice Sheets Exist Today in Greenland and Antarctica?

Yes. Both Greenland and Antarctica have massive ice sheets formed by millennia of snow accumulation and compaction.

Greenland Ice Sheet

• Covers ~80% of Greenland
• Volume: ~2.85 million km³
• Average thickness: ~2,150 m
• Vulnerable to accelerated melting from climate change

Antarctic Ice Sheet

• World's largest: ~14 million km²
• Volume: ~26.5 million km³
• Average thickness: ~2,160 m
• Divided into East (stable) and West (vulnerable) sheets

These ice sheets critically regulate sea levels, reflect solar radiation, and influence global weather. Their melting due to climate change has far-reaching impacts.
