Egypt’s coastal city of Alexandria, which has survived invasions, fires and earthquakes since it was founded by Alexander the Great more than 2,000 years ago, now faces a new menace in the form of climate change.
Rising sea levels threaten to inundate poorer neighborhoods and archaeological sites, prompting authorities to erect concrete barriers out at sea to break the tide. A severe storm in 2015 flooded large parts of the city, causing at least six deaths and the collapse of some two dozen homes, exposing weaknesses in the local infrastructure.
