The Sahara covers roughly 8% of Africa's land area, not Earth's total land area. It spans about 3.6 million square miles, which is about 5% of the world's land.

Desertification, driven by overgrazing, deforestation, and climate change, is pushing the Sahara's boundaries south into the Sahel region at an alarming rate.

Snow fell in the Algerian town of Ain Sefra in 2018, a rare event due to cold air from Europe. The Sahara averages under 1 inch of rain annually in its driest regions.

Camels store fat in their humps, not water. They conserve water through efficient kidneys and can go long periods without drinking, but the hump is for energy.

Around 10,000 years ago, the Sahara had grasslands, lakes, and rivers due to shifts in Earth's orbit. Rock art in the region shows giraffes and hippos.

About 10,000 years ago, the Sahara had a wet 'African Humid Period' with savannas, lakes, and even hippos—until climate shifts dried it out.

Around 10,000 years ago, the Sahara was a green savanna with lakes and rivers due to changes in Earth's orbit. This period, called the African Humid Period, ended about 5,000 years ago.

The Sahara has permanent settlements, including the city of Tamanrasset in Algeria and numerous oases towns. Over 2 million people live in the Sahara region.

Camel spiders can run fast (about 10 mph), but not 30 mph, and they don't scream. They hiss by rubbing their legs together. This myth comes from exaggerated soldier stories during the Gulf War.

The Nubian Sandstone Aquifer System beneath the Sahara holds fossil water that fell as rain over 10,000 years ago. It's non-renewable but supplies water to Libya, Egypt, and Sudan.

Snowfall has been recorded in the Sahara several times, most notably in 2018 near Ain Sefra, Algeria, due to rare cold air intrusions.

Around 10,000 years ago, the Sahara had a wet phase called the 'African Humid Period,' with grasslands and large lakes like Lake Chad.

Only about 15% of the Sahara is sand dunes; the rest is rocky hamada, gravel plains, and mountains.

Snow has fallen in the Sahara several times, most famously in 1979 and 2018 in Algeria, though it melts quickly due to the sand's warmth.

Camels store fat in their humps, not water. They conserve water through efficient kidneys and can drink up to 30 gallons at once.

While the Sahara is sunny, the Atacama Desert in Chile gets the most direct solar radiation due to its high altitude and clear skies.

Snow has been recorded in the Sahara several times, most notably in 1979 and 2018, especially in higher elevations like the Aïr Mountains.

Camels’ humps store fat, not water. They conserve water through efficient kidneys and dry feces, and can drink up to 30 gallons in minutes.

The hyper-arid core of the Sahara, like the Libyan Desert, can go decades without measurable rain. One station recorded no rain for over 50 consecutive years.

While natural cycles play a role, human activities like overgrazing and deforestation accelerate desertification. It’s not purely natural expansion.

Snowfall occurs in the Sahara roughly every few decades, with notable events in 1979, 2016, and 2018. The cold air from higher altitudes meets moisture, creating rare snow in the desert.

The Sahara fluctuates seasonally and over decades due to climate patterns like the African Monsoon, growing or shrinking by up to 10% annually.

The Sahara is too dry for most carnivorous plants. Only a few species exist in sparse, damp pockets, nowhere near 200.

Emi Koussi, in the Tibesti Mountains of Chad, stands at 11,302 feet. It's a shield volcano and the highest peak in the Sahara, though many assume it's in Morocco or Algeria.

While desertification is a concern in some regions, satellite data shows the Sahara's size fluctuates naturally with climate cycles. It has actually shrunken in some decades due to increased rainfall.

Sahara sand is mostly derived from ancient sandstone and quartzite, not primarily the Atlas Mountains, which contribute a minor fraction.

Vast aquifers, like the Nubian Sandstone Aquifer System, hold ancient water trapped thousands of years ago, used for irrigation today.

The tallest sand dune in the Sahara is about 1,500 feet high, less than half the Empire State Building's height (1,454 feet to roof). No dune tops 2,000 feet.

Silver ants of the Sahara have reflective hairs and produce heat-shock proteins, allowing them to forage in extreme heat.

The Nubian Sandstone Aquifer System lies beneath the Sahara, containing fossil water. It's one of the largest underground freshwater reserves in the world.

While desertification is real, the Sahara's expansion varies by region and is not a steady 30 miles per year. Estimates are more modest and disputed.

Desertification and shifting climate patterns cause the Sahara to advance south into the Sahel region at roughly 30 miles annually.

The Sahara holds records for high temperatures, but the hottest spot is the Lut Desert in Iran, and Death Valley holds the highest air temperature.

NASA satellites show that Saharan dust clouds travel across the Atlantic and provide essential phosphorus to fertilize the Amazon basin.
