Our planet is getting hot, so we will have lot of vapor -> rains -> fresh water. Just collect it instead of dumping it into river or ocean.

- tomp 11y agoI'm not so sure about this. Water -> vapor -> water loop only works if there's a temperature gradient - you need heat to vaporize water and coldness to condense vapor into water again. If the whole planet is getting hotter, the atmosphere could simply get more humid, with no more rain/fresh water.
- lisivka 11y agoWe have such temperature gradient every night. We have lack of rains in some areas because they are too hot at evening, because of deforestation, but this is an another story. We also can create temperature gradient by adding shade at some areas, e.g. using SO2 at altitude of about 20km.
