Are Non-Glaciated Parts of Antarctica Like a Desert? No

No. While Antarctica is a polar desert by precipitation (<200 mm/year), the ice-free areas (<0.4% of continent) differ from hot deserts:

• Cold, not hot: Mean temps far below freezing.
• Precipitation is snow—accumulates, compacts to ice over millennia.
• Ice sheets (up to 4.7 km thick) cover 99.6%; ice-free zones (Dry Valleys, nunataks) are cold, hyper-arid, but not sandy deserts.
• Unique ecosystems: Microbial life, extremophiles in cryptoendolithic habitats.

They're polar deserts—a distinct biome, not "like the Sahara."
