A solar pond is a three-dimensional, open-air pit, filled with water endowed with special properties. It receives solar energy through insulation, then the trapped heat is extracted from it from the water lying at the bottom of the pond. When solar energy falls onto the pond, it heats the water, splitting it into three sections: the first section is the uppermost layer, or Surface Zone, containing fresh water with a low level of salinity. This owes to the fact that salts gather at the bottom. The second layer is the middle layer, called the insulating layer or Insulation Zone, whose … Continue reading →

For many years now, the Mediterranean has been facing problems leading to a situation of serious environmental degradation. An increase in the temperature and salinity levels has been recorded during the second half of the 20th century in the Mediterranean Sea. However, this increase does not follow progressive trend and periods of temperature alternation have been observed. Following several climate change scientific reports, sea level trend at the global scale is higher than at the regional scales. Furthermore, in the regional scale there are other influence factors such the atmospheric pressure and the wind. In addition, the small rises in temperature … Continue reading →

Life on an island in the South Pacific has long been considered an idyllic location. But that once reality is becoming a daunting nightmare for the people of Kiribati (pronounced Ke-ree-bas). This nation consists of three archipelagos in the centre of the Pacific Ocean. The total land mass is approximately 811km2 and is spread across 3.5 million km2  of ocean. Of the 33 island and atolls, two-thirds of these land masses are inhabited. The total population of 120,000 people predominantly live on the main island, Tarawa. With the growing trends in the changing global climate, this small Pacific community is … Continue reading →
