Rising sea levels are becoming increasingly intimidating. The ancient city of Alexandria in Egypt could be of the early victims of global warming, scientists warn.
Hundreds of concrete barriers have been built to protect the city founded by Alexander the Great from the waves of the Mediterranean Sea.
The crumbling barriers of Alexandria's Eastern Harbor, however, are no match for a sea that scientists say will rise between one and three feet by the end of this century. They predict that rural towns and urban areas along Egypt's northern coast will be flooded, turning millions of people into environmental refugees and threatening some of the country's ancient landmarks.
In 1994, a team of underwater archeologists discovered what they believe to be the remains of the Pharos Lighthouse, one of the Seven Wonders of the ancient world. The tower, which was more than 350 feet high, guided ships into Alexandria's Harbor with a beacon of fire. Emad Khalil, an underwater archeologist at the University of Southhampton in the United Kingdom, says the antiquities that are still above ground may one day suffer the lighthouse's fate.
"One of the … issues we are facing is not just the sea level rising, but the violence in the sea and the waves affecting the corniche, the wall surrounding the Eastern Harbor," Khalil says.
Alexandria's residents might not notice the change, but rural farmers say they're already living with the consequences as salty water from the rising Mediterranean pushes into the fertile Nile Delta and contaminates the groundwater used to irrigate crops. Just a few miles from the city's port, Khamiesa Abdelsalam Tuto says the sand that covers the trunks of her family's date palms and tomato plants is quickly being replaced by salt, reports Liane Hansen for NPR (National Public Radio) in the US.
