Rising sea levels threaten coastal cities and one of these is Alexandria, a city that has survived invasions, earthquakes and fires over the last 2000 years but may not withstand seawater.
Alexandria, which is washed by the Mediterranean Sea, is home to more than 5 million people and is one of Egypt’s main industrial centers. The first changes, as declared by the Egyptian water resources ministry, are already visible today: the sea level has indeed risen by 1.8 mm every year until 1993. From 1993 to 2012 it rose by 2.1 mm to year and from 2012 onwards of 3.2 mm per year, increases that may seem insignificant but that could indicate a substantial acceleration in raising the water level.
To favor the sinking of the land are also the various dams built on the Nile river, in particular upstream, which are exacerbating the same effects of rising sea levels with consequences that could be catastrophic in a few decades.
The area of the citadel of Qaitbay which houses a medieval fortress built on the ruins of the lighthouse could be particularly vulnerable.
Even the citizens experience these climatic changes: every year that passes the waves are always higher and the winters are getting colder as well as the increasingly hot summers.
