Sahara Desert
The world's largest hot desert spanning 9.2 million km² of hyper-arid sand ergs, reg plateaus, and oases.
0°C at night to 50°C in afternoon (32°F - 122°F)
Less than 100 mm (4 in) per year, with years of zero rain
Hyper-arid with extreme diurnal thermal fluctuations
Egypt, Algeria, Chad, Libya, Mali, Mauritania, Morocco, Niger, Sudan, Tunisia
Ecosystem Structure & Biodiversity
Despite extreme thermal shifts and water scarcity, the Sahara supports hyper-specialized xerocoles—animals adapted with reflective fur, concentrated renal systems, subterranean burrows, and oversized appendages designed for heat dissipation.
- ✓The Sahara is roughly equal in size to the entire United States or China.
- ✓Only 25% of the Sahara is sand dunes (ergs); the remaining 75% is rocky gravel plateau (reg).
- ✓The Sahara was a lush green savanna covered in lakes and hippos just 6,000 years ago.
Rulers of the Food Chain
Desertification pushing beyond boundary zones, motorized over-hunting, and expanding solar infrastructure disturbing sensitive dry dunes.
