In March 2018 authorities in Alexandria, Egypt, began removing five hundred residents from their homes along the Al Mahmoudeya canal—dug in 1820 under orders from Viceroy Mohamed Ali—and into high-rises. “There are many areas,” says Alexandrian climate scientist Mohamed El Raey, “that are located at least three meters below sea level. They will have to be abandoned and the people relocated.” Estimates suggest near-term rise in sea levels will inundate a third of the city.
