• Highest Point: Emi Koussi, a shield volcano in the Tibesti Mountains, at an elevation of 3,415 meters
• Lowest Point: Qattara Depression in Egypt, reaching 133 meters below sea level

The Sahara"s boundaries are defined by the Atlantic Ocean to the west, the Red Sea to the east, the Mediterranean Sea to the north, and the Sahel savanna to the south. Its location and vast size contribute significantly to its diverse climate and ecological zones, ranging from hyperarid central regions to the more vegetated northern and southern fringes.

Despite its harsh environment, the Sahara has been a cradle of ancient civilizations and remains home to various human settlements and unique biodiversity. Its vast expanse and distinct geographical features continue to attract scientific and cultural interest worldwide.

The latitude of the Sahara Desert is approximately 25.284266.

The Sahara Desert, known for its extreme climate, is the world"s hottest large land area. It encompasses two distinct climatic regimes: the dry northern subtropical climate and the dry southern tropical climate. The northern subtropical climate is characterized by high annual and diurnal temperature ranges, cold to cool winters, hot summers, and two primary periods of precipitation. In contrast, the southern tropical climate experiences a strong yearly temperature cycle, mild and dry winters, and a hot, dry season followed by variable summer rains.

The climate of the Sahara is predominantly hot and dry. Summer temperatures commonly range between 100.4°F and 104°F (38°C to 40°C), but can reach extremes such as 136°F (58°C) in Aziziyah, Libya. The region"s unique geography, including the Algerian Desert and other areas, contributes to these high temperatures. Despite its hot days, the desert experiences near-freezing temperatures at night, especially at higher elevations where occasional snowfall occurs.

Cloudless skies dominate the Sahara, allowing for an extraordinary amount of sunshine, reaching up to 3600-4300 hours of bright sunshine annually. This high level of sunshine, combined with the desert"s low humidity, results in minimal vegetative cover and sparse rainfall. Precipitation in the Sahara varies greatly, with some regions receiving as little as 0.04 inches of rain annually, while others, particularly along the northern and southern fringes, receive between 4 and 10 inches due to influences from the Mediterranean Sea and the Intertropical Convergence Zone, respectively.

Climate change has notably impacted the Sahara, contributing to its expansion by about 10% since the early 20th century. This expansion is partially attributed to human-induced climate changes, affecting natural climate cycles. The introduction of large-scale wind and solar farms in the Sahara is being explored as a potential mitigation strategy against these climate change effects, offering possibilities for increased precipitation and vegetative growth in the region.

Overall, the Sahara"s climate is marked by its harsh, arid conditions, significant temperature fluctuations, and sparse rainfall, all of which shape the unique environmental landscape of this vast desert.

The Sahara Desert, despite its harsh climate, supports a diverse range of flora and fauna, each uniquely adapted to the extreme environmental conditions. The vegetation is generally sparse, with pockets of life found in highlands, oases, and along wadis. Plant life includes heat- and drought-tolerant grasses, shrubs, and trees. Notable species include various halophytes (salt-tolerant plants), olive, cypress, mastic trees, Acacia, Artemisia, doum palm, oleander, date palm, and thyme.

Animal life in the Sahara is equally remarkable. Relict tropical fauna includes catfish and chromides in certain areas, while the mammalian population includes gerbils, jerboas, hares, hedgehogs, Barbary sheep, scimitar-horned oryx, gazelles, deer, wild asses, baboons, hyenas, jackals, foxes, and weasels. The birdlife exceeds 300 species, including water and shorebirds, ostriches, raptors, secretary birds, guinea fowl, and Nubian bustards.

Adaptations are a key part of survival in this environment. For instance, the jerboa, a small rodent, is known for its ability to jump high and run fast, and it can extract enough water from its food to survive. The fennec fox, with its large ears, excels in hearing and dissipates heat efficiently. The monitor lizard, found in various sub-species, is venomous and highly adaptable to different environments. The ostrich, known for its speed, can travel long distances and has a keen sense of sight and hearing. The sidewinder, or horned viper, uses a unique sideways movement to navigate the sands effectively.

Other notable species include the death stalker scorpion, one of the most venomous scorpions in the Sahara, and the addax antelope, known for its ability to cross the Sahara sands on its flat feet. The scarab beetle, a symbol of ancient Egyptian culture, has an impressive ability to subsist almost entirely on animal waste. The Dorcas gazelle is adapted to evade predators with its high-speed and reflexive jumping, a behavior known as "stotting". Lastly, the Sahara desert camel, an iconic symbol of desert life, stores fat in its humps which can be metabolized during food scarcity.

The Sahara Desert, encompassing an area as large as the United States, has a sparse population of about 2.5 million inhabitants, primarily due to its harsh environment. Despite these conditions, human settlements have persisted in regions where scarce vegetation supports grazing animals or where reliable water sources exist.

Historically, the Sahara was more widely occupied, as evidenced by stone artifacts, fossils, and rock art that reveal the presence of humans alongside game animals such as antelopes, buffalo, giraffe, elephant, rhinoceros, and warthog. Prehistoric settlements near ancient Saharan lakes show evidence of hunting, fishing, and early agricultural practices.

The introduction of domesticated livestock nearly 7,000 years ago led to the development of nomadic pastoralism, with cattle-herding groups believed to be ancestral to modern Berbers or Zaghawa. Agriculture in the Sahara dates back about 6,000 years with the cultivation of barley and emmer wheat in Egypt, thought to be introduced from Asia.

Archaeological findings suggest diverse populations inhabited the Sahara, leading to occupational specialization and economic interdependence among different groups. External trade played a significant role, with copper from Mauritania reaching the Bronze Age civilizations of the Mediterranean by the 2nd millennium BCE.

The introduction of Islam between the 7th and 11th centuries into North Africa led to significant cultural changes in the Sahara. It became the dominant social force, expanding through trade routes and influencing the cultural and economic systems of the region.

Trans-Saharan trade routes, thriving from 1200 to 1450, linked the wealthy empires of West Africa to the Mediterranean Sea and Indian Ocean. These routes were essential for the exchange of valuable commodities like gold and salt, and for the spread of Islam, contributing significantly to the cultural and economic development of the region.

The Sahara"s inhabitants, categorized as pastoralists, agriculturalists, or specialists, adapted to the desert"s harsh conditions. The pastoral lifestyle was common where pasturage was available, with cattle along the southern borders and sheep, goats, and camels as mainstays in the desert.
