Make the Desert Bloom

 Tomas Pueyo has an idea to help combat global warming and rising seas. His idea is to create new seas by flooding several below sea level basins, such as the Dead Sea or Death Valley with seawater to create or enlarge inland seas. Here is an image from his Substack pages showing how Egypt's Qattara Depression could be flooded to create a sea. This image was cropped to better fit the format of this page.

Because the depression is below sea level pipelines from the sea can generate electricity while bringing water in from the Mediterranean Sea. This electricity could be used to desalinate some of the sea water and pump that water into a reservoir. 

The article discusses how the Mediterranean Sea was similar to the Dead Sea during the Messinian Salinity Crisis. The sea level was very low and the basin was very hot, dry and salty. This period ended with the Zanclean Flood when the Straits of Gibraltar were breached and the Atlantic Ocean emptied huge quantities of water into the basin. The rising sea levels made the climate of the surrounding areas wetter and cooler and resulted in a large increase in vegetation. Eventually a thriving ecosystem formed and the suggestion is that creating new seas would have a similar effect. Here are some suggested locations where new seas could be created. Once again, I have altered the original image, breaking it into hemispheres for readability.

Israel and Jordan have both considered doing this for the Dead Sea. International political issues have gotten in the way but most of these other candidates don't involve international borders so they could be more easily done. There is much more to read about this process in Uncharted Territories.
