The Sahara Desert spans approximately 9.2 million square kilometers and is in fact the largest hot desert in the world. Located in North Africa, it covers parts of eleven countries, including Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan, Algeria, and Tunisia. This expanse of arid land is characterized by its often harsh climate, with massive temperature swings that can soar above 50 degrees Celsius during the day and plummet below freezing at night.
The Sahara is built up of a diverse amount of geographic landscapes, comprising mainly of sand dunes, gravel plains, rocky plateaus, and even some mountain ranges, such as the Ahaggar (with peaks rising above 9,500 feet) and Tibesti ranges (containing Mount Emi Koussi, a peak that rises a lofty 11,204 feet). Its iconic sand dunes, particularly in Algeria and Libya, can reach heights of up to 180 meters!
Human settlement in the Sahara Desert is limited but historically significant. Nomadic tribes, such as the Tuareg and Berbers, have traveled this desert for centuries, passing through it mainly for trade while other groups of people wouldn't dare try (understandably). There are some oases, providing vital water sources, that serve as hubs for small to medium-sized towns and cities, like Ghardaia in Algeria and Timbuktu in Mali, the latter being a UNESCO World Heritage site.
The short answer is yes. But, how do we know this? A number of studies, including one that spanned 93 years by researchers at the University of Maryland, have concluded that the sands of the Sahara have been expanding for some time, primarily southward into the Sahel region. Having grown an estimated 10% since 1920, this is an undeniable fact that continues to be demonstrated year after year, with expansion often at its fastest during the summer months when the already dry desert becomes even more absent of water.
The growth of the Sahara Desert is mainly driven by natural climate variability and human-induced climate change. Naturally, a process called the Atlantic Multidecadal Oscillation (AMO), a periodic climate cycle in the North Atlantic Ocean, significantly influences this expansion by affecting regional rainfall patterns. In the case of the Sahara, during warm phases of the AMO, this region experiences drier conditions, causing the desert landscape to spread.
The Sahara Desert's expansion is causing significant environmental and socio-economic issues. As mentioned, the southward creep of the desert into the Sahel is exacerbating drought conditions, making it difficult for local populations to maintain their agricultural and pastoral livelihoods. The loss of this farmland leads to food insecurity, pushing communities into poverty and increasing competition for resources. This can, and sometimes has, resulted in conflict and displacement as people migrate in search of more habitable areas.
As mentioned before, the Sahara's growth results from the complex interplay between natural cycles and climate change. Tackling this issue requires understanding these drivers and implementing strategies to mitigate their impacts on vulnerable regions. Reducing greenhouse gas emissions and adopting sustainable land management practices are some of the steps we can also take part in to help address the root causes of desertification.

As the largest among the Siren family, the Greater Siren, found in North America's southeastern coastal plains, can measure up to 38 inches. It demonstrates paedomorphism, retaining external gills their entire life and lacking hindlimbs, pelvic girdle, and eyelids while sporting an unfused pectoral girdle.
Greater sirens are nocturnal hunters, preferring invertebrates such as insects, crustaceans, molluscs, and small fish, thus taking a midlevel predator role in the aquatic food web. .
The Great Spotted Woodpecker is a bird species in Europe and northern Asia. It has black and white plumage, with males having a red dash on the back of their heads. This bird has a stout beak and a long, sticky tongue, perfectly adapted for drilling into tree trunks and catching insects.
Its diet consists mainly of insects, including seeds, nuts, and bird eggs. Moreover, the Great Spotted Woodpecker is adaptable, making its home in various environments, including forests, parks, and gardens.
The Greater Banded Hornet lives in South and Southeast Asia. It features distinctive yellow and black bands and can grow to an inch.
Likewise, they make their homes in complex, large nests within the hollows of trees or underground cavities, which can house several thousand colonies.
The hornets consume other wasps, beetles, caterpillars, nectar, and fruit. They are also essential pollinators within their ecosystems.
Notably, the queen is the sole egg-layer at the heart of each colony, surrounded by her daughters who serve as workers.
The workers use hunting methods such as "hawk predation," capturing and killing other flying insects in mid-air. Meanwhile, they also participate in "aerial jousting" to determine dominance.
Wetlands are areas that are totally or partially covered with water. They are transitional between permanently flooded deep water areas and areas with their water tables near the surface. Sometimes, shallow water covers the surface of the land. Examples of wetlands are:
brackish marsh,
fresh marshes,
salt marshes,
swamps,
wet prairies,
bogs,
forested wetlands,
and vernal pools.
You can also refer to wetlands as areas with dominant natural water saturation levels, determining the soil development processes and the plants and animals inhabiting them. The covering of water in some wetlands could be permanent or seasonal.
You read that right. The Indian Rhino is semi-aquatic and a gifted swimmer. They thrive in habitats near water sources, such as marshlands, grasslands, and alluvial floodplain forests. The Indian Rhino uses water as a defense mechanism to escape potential threats. Swimming also allows them to move between different areas and access abundant vegetation, including aquatic plants, reeds, and grasses growing near the water.
In the early 1900s, there were approximately 500,000 rhinos found in Africa and Asia. However, by 1970, the rhino numbers dropped to 70,000. Unfortunately, today there are only around 27,000 remaining rhinos in the wild. Rhino poaching remains their most significant threat. Poachers target their valuable horns, which are highly sought-after trophies in the illegal wildlife trade and traditional Asian medicine markets.
Poachers relentlessly hunt and kill rhinos, pushing several rhino species to extinction. To make matters worse, the increasing human populations also contribute to habitat loss for these animals. Climate change is intensifying drought and affecting vegetation, further compounding the challenges rhinos face.
IUCN lists the three species of rhino—black, Javan, and Sumatran—as critically endangered species. The white rhino (Ceratotherium simum) is listed as near threatened, with an estimated population of around 18,000. Despite being listed as vulnerable, the Greater One-Horned Rhino (Rhinoceros unicornis) has one of Asia's most successful conservation stories. Thanks to the conservation efforts of Indian and Nepalese authorities, their population has significantly increased.
Conservation efforts to protect rhinos include anti-poaching measures, habitat protection, and community engagement. Well-trained rangers with advanced technology apprehend poachers and dismantle trafficking networks. Translocation, population management, and reducing demand for rhino products are also crucial.
Organizations like the International Rhino Foundation and Save the Rhino International, alongside governments and communities in countries with rhino populations, are actively involved in rhino conservation.
Be part of the solution by simply spreading these rhinoceros facts.

The Great Mosque of Sana'a (Arabic: الجامع الكبير بصنعاء, al-Jāmiʿ al-Kabīr bi-Ṣanʿāʾ) is an ancient mosque in Sana'a, Yemen, and one of the oldest mosques in the world.[1] The mosque is said to have been founded in the early Islamic period, suggested to be in 633.[2][3][4][5] While the precise date of construction is unknown, the earliest recorded renovations occurred under Caliph al-Walid I in the early 8th century, implying a possible earlier date of construction.[4] The mosque was reportedly built in part from spolia from the Himyarite-era Ghumdan Palace and from the Axumite Christian Church of al-Qalis that formerly occupied the site.[1][4] The Great Mosque is the largest and most notable of over one hundred mosques in the Old City of Sana’a.[3]
