Alexandria immersed in the sea due to climate change, research warning. Since the establishment of Alexander Macedon, this old city has been the place of some of the most important events in history before the birth of Cleopatra. But now scientists warn that Alexandria is immersed in the sea due to the increase in the levels of the oceans.

A new study showed that the 2300 -year port city in Egypt was experiencing a sharp mutant of Muslims about the number of crashes of buildings, Daily Mail wrote. The researchers warned that a city where miracles like the ancient world like the great Alexandrian library and the Alexandria lighthouse have gradually disappeared.

Over the past decade, the number of buildings of Alexandria's buildings has increased a year before the “alarm” each year, because the saline water penetrates the city's foundation deeper. Over the past 20 years, 280 buildings have been destroyed due to coastal erosion and 7,000 other buildings are now threatened to collapse in the future.

The leading author Sarah Fuad, a landscape architect from Munich Technical University, said: For centuries, building Alexandria is the miracle of the technique that can withstand earthquakes, storms, tsunamis and now a change of change. It takes many millennia. “

Founded by Alexander the Great in 331 BC, Alexandria was once the largest city in Earth and was one of the most important places in the ancient world, reminding Daily Mail.

The city, called the “Mediterranean bride”, thanks to its location on the coast, has become an important commercial and transport center, connecting the Middle East and Europe. However, the closeness to the country, which has made the city prosperous, now threatens its destruction due to the rapid overflow of the sea. When the planet heats up due to the accumulation of greenhouse gases in the atmosphere, the average temperature of the ocean increases.

As the Daily Mail continues, how water is hot, it also expands and combines with fresh water due to the rapid melting of the shield, increasing the level of the oceans.

According to the National Ocean and Ocean Research Agency (NOAA), since 1880, the level of oceans has increased by 20-23 cm, and only since 1993, this increase is 10 cm.

A recent study conducted by the University of Nanyan Technology (NTU) in Singapore showed that by 2100, the level of oceans could increase to 1.9 meters if carbon dioxide emissions (CO2) will continue to increase.

The researchers have agreed on satellite photos with historical cards to see how fast the city coast has disappeared since the 1880s. The analysis showed that in the past few decades, the coast of Alexandria has moved into the country by tens of meters, and some areas withdraw 3.6 meters per year.

Co -author of the study, Doctor Essam Hegegie, a water resource expert at the University of Southern California, said: “We are witnesses of the gradual disappearance of historic coastal cities and Alexandria defeated anxiety.

But the increase in sea level is not sharp to have catastrophic consequences, daily notes.

Dr. Hegegie, a water resource expert at the University of Southern California, said: “Our research rejects the widespread misconception that you will just need to worry when sea level increases by a meter.”

The increase in sea level only a few centimeters increases the risk of floods and most importantly allows salt water to penetrate into coastal cities. As the water level increases, they are in contact with the foundations of the buildings and due to the penetration of salt water, the structure is destroyed for a long time before they are in direct contact with the sea.

The researchers took the land samples throughout the city to study the “chemical impression” involving the penetration of salt water.

The co -founder of the study, Professor Ibrahim Saleh, a land scientist from Alexandria University, said: “Our analysis of the isotopes showed that buildings were destroyed from the bottom up, because the penetration of sea water destroyed the foundation and weakened the soil.

This led to the collapse of hundreds of buildings located more than a kilometer from the coast.

Researchers are worried that these issues are characteristic not only for Alexandria and may affect coastal cities around the world.

A recent NASA study showed that some areas of California, including San Francisco, in the literal sense, plunged into the ocean faster than the level of the sea increased.

When landslides fall into sea levels, salt water can penetrate deeper into the country and destroy more and more buildings.

To solve these problems, researchers offer a number of feasible solutions, including the construction of sand dunes along the coast, building high -class or resettlement buildings of people to the most vulnerable areas.

Dr. Hegegie concluded: “Historical cities, such as Alexandria, are a cradle of cultural exchange, innovation and history, which is important for our general human heritage conservation.
