If no immediate action is taken to counter the harm, desalination, in combination with climate change, will increase the Gulf’s coastal waters temperature by at least five degrees Fahrenheit across more than 50 percent of the area by 2050, according to a 2021 study published in the Marine Pollution Bulletin on ScienceDirect, a site for peer-reviewed papers.
You’d think the brine could be “mined” for lithium, sea salt, and other mineral content. Then disposed of in the desert rather than thrown back into the sea.
At that point, you’re evaporating all the water out to get the minerals left, which can be a lot more energy intensive as the boiling point of the brine will get higher as water is removed.
And in the end, you’re going to end up with a gigantic salt flat in a windy part of the world. If you are lucky, all you are doing is just making a part of the land more toxic. If you are unlucky, that salt could get airborne and cause its own environmental issues.
Interesting. We’re going to have to figure out something. The middle eastern desert isn’t the only place running out of fresh water.
I will note that evaporation pools are nothing new and don’t require a lot of energy. If you can extract the minerals that are worth something, the process could pay for itself.

Perhaps, but this is going to radicaly alter both how current desalinization plants operate and the supply chain of salt.
It doesn’t seem to be insurmountable, but it is going to be a big deal going forward. At least the main users of desalinization technology are in locations with abundant solar energy.
