Atlantropa, the Messinian salinity crisis, and other Alternative Worlds

Out of this age of crisis, a book has just been published that aims at fully opening the doors of imagination to show how audacious we humans are when in need to restart from scratch:

Alternative Worlds, Blue-Sky thinking since 1900 (R. Vidal & Cornils, eds.; Peter Lang Publishing, Bern, ISSN 3034317875, 9783034317870)

The book includes an article by the editor Ricarda Vidal (King’s College London) giving an updated perspective on the Atlantropa Project (1929). Atlantropa intended to reduce the area of the Mediterranean Sea by 30% by damming the Strait of Gibraltar, allowing natural evaporation to lower the sea level by a couple of hundred meters. With this project, Herman Sörgel sought to control the inflow of Atlantic seawater to generate electricity, to exposing new inhabitable land (former submarine continental shelf), and to use the Nile River to irrigate a vast part of the Sahara Desert.
The project thus aimed at mimicking what nature did 6 million years ago during the Messinian Salinity Crisis, and that's why I coauthor with Vidal a second chapter dealing with what we know about this ancient salinization and desiccation of the Mediterranean from a scientific perspective, and about the footprint this geology left in western culture.
The rest of the volume discusses fascinating Alternative Worlds including seasteads, planned cities, the high-rise age, and the promising worlds-to-be in the outer space.
