Once the storm passed, it was assumed that the million or so Katrina evacuees would, as in past cases, return to repair and rebuild their homes. Some 700,000 did return, but close to 300,000 did not. They are no longer evacuees. They are the first large wave of modern climate refugees.
One of the defining characteristics of our time is the swelling flow of environmental refugees, including those displaced as a warmer climate brings more-destructive storms and rising seas. The prospect for this century is a rise in sea level of up to 6 feet. Even a 3-foot rise would inundate parts of many low-lying cities, major river deltas, and island countries. Among the early refugees will be millions of rice-farming families from Asia’s river deltas, those who will watch their fields sink below the rising sea.
The flow of rising-sea refugees will come primarily from coastal cities. Among those most immediately affected are London, New York, Washington, Miami, Shanghai, Kolkata (Calcutta), Cairo, and Tokyo. If the rise in sea level cannot be checked, cities soon will have to start either planning for relocation or building barriers that will block the rising seas.
River deltas contain some of the largest, most vulnerable populations. These include the deltas of the Mekong, Irrawaddy, Niger, Nile, Mississippi, Ganges-Brahmaputra, and Yangtze Rivers. For example, a 6-foot sea level rise would displace 15 million Bangladeshis living in the densely populated Ganges-Brahmaputra delta. The London-based Environmental Justice Foundation reports that “a one meter [3 foot] sea-level rise would affect up to 70 percent of Nigeria’s coastline affecting over 2.7 million hectares. Egypt would lose at least 2 million hectares in the fertile Nile Delta, displacing 8 to 10 million people, including nearly the entire population of Alexandria.”
Low-lying islands will also be hit hard. The 39 members of the Alliance of Small Island States stand to lose part or all of their territories as sea level rises. Among the most immediately threatened are Tuvalu, Kiribati, and the Marshall Islands in the Pacific Ocean and the Maldives in the Indian Ocean. Well before total inundation, islanders face salt water intrusion that can contaminate their drinking water and make it impossible for deep-rooted crops to survive. Eventually, all crops will fail.
