Israel does this for a different reason: To collect minerals from the dead sea.
It doesn't increase rainfall.
Israel is actually desalinating water and rejuvenating a river, which eventually will reach the dead sea (although that's not why they are doing it, but it makes the point that evaporating water isn't doing much).
Maybe you mean on a far larger scale?
Well - the ocean itself is much larger, and water evaporates from its surface all the time. Humans aren't going to make an evaporation zone larger than the ocean.
Also: Water does not (mainly) evaporate because of heat, but rather because of wind. There's lots of heat in the desert, but not much wind. The ocean has a ton of wind.
- eklitzke 3y agoActually deserts can be quite windy, especially deserts near the ocean. Wind forms when there's a pressure differential, and the most common reason for a large pressure differential is when there are two adjacent areas with a significantly different temperature. So when you have a desert next to the ocean, the desert cools at night and then during the day, as the air in the desert heats up, it lowers the air pressure on land and pulls in air from the cooler air over the ocean. This phenomenon is why the SF Bay Area consistently has high wind and good sailing conditions during the summer, especially in the afternoons. That said, none of this contradicts the overall point you were making.
