Namibia – June 17th, 2013

Plumes of dust blow southwestwardward off the coast of Namibia, by both the rocky, tan northern portion and the sandy, orange southern portion of the Namib Desert. In the full image, similar wispy plumes of dust can be seen much further southward along the coast, for much of the length of the sandy desert.

Climate Change Affecting Wildlife in Etosha Pan, Namibia

Namibia – April 3rd, 2013

Visible at the top center of this image is the Etosha Pan, in Namibia. Although it is one of the harshest and most barren areas on Earth, the Pan and the surrounding sweetveld savannah plains are home to more than 114 mammal and some 340 bird species.

This animal life is sustained only because of underground springs that form waterholes on the outskirts of the pan. These waterholes allow animals to fight off the dry and the heat as they migrate across Etosha, seeking refuge from temperatures that can reach as high as 120 degrees Fahrenheit.

Without a subterranean water table and the numerous places where it reaches the surface, little game would have been attracted to the region in the first place. There are indications, however, that the climate may be changing. 1995 was the 18th year of below average rainfall in Etosha. Large herbivores, as a result, have become more widely dispersed in search of grazing, and the predators alsoseem to be ignoring their previous range limits to widen their search for prey. Lion pride structure has become loose, with individuals traveling huge distances.

Climate Change Creating Harsher Conditions in Namib Desert, Namibia

Namibia – January 27th, 2013

Living in the Namib desert was never easy due to extreme temperatures and sparse vegetation, but signs that climate change may be worsening the already harsh conditions in this area of desert have led to concern over how local farmers will water crops.

Namibia is the driest country in sub-Saharan Africa, with annual rainfall varying between 30 millimetres (1.2 inches) in the desert to as much as 500 millimetres in the extreme northeastern Caprivi Region. Climate change may already be making the situation worse, with increases in temperature of around 1.2 degrees Celsius observed.

According to scientists, in recent years, hot temperatures are getting hotter, hot days of above 35 degrees Celsius are becoming more frequent and the number of cold nights decreasing. Rainfall seasons are already starting later and ending earlier, affecting subsistence farmers who grow staple foods (click here to read more).

Namibia - May 6th, 2012

A faint phytoplankton bloom hangs in the waters off the shores of Namibia. The bloom is situated west of the southern part of the Namib Desert, an immense dunefield with tall, orange sand dunes. Phytoplankton blooms are common in this area due to the mixing of hot and cold ocean currents.

Namibia - April 15th, 2012

This image focuses on the bright red and orange sand dunes of the souther Namib Desert. The Southern Namib (between Lüderitz and the Kuiseb River) comprises a vast dune sea with some of the tallest and most spectacular dunes of the world: in the Sossusvlei area, several dunes exceed 300 meters (984 ft) in height. As one moves eastward, the dunes give way to more rocky terrain.
