I don't mean this to sound snarky. I'm genuinely curious where you think the water will go, if not to other places on earth.

We lose atmosphere to space everyday.

And we also gain water from space through meteorites every day.

> Earth is a closed system, so we should expect to see water storage decline in some areas and flooding increase in some areas. Of course, Earth is a closed system, but I am not sure it is that closed.

I afraid that a lot of fresh water is going to become an ocean water. Flooding theory creates the impression of transferring fresh water from one place to another where it will remain just as fresh. It is incredibly hard to create a fresh water from salty one.

Into the ocean.

The ocean covers the majority of the Earth's surface. The ocean is full of salt.

Water which rains out over the oceans is unusable as drinking or irrigation water without expensive processing (desalination).

If historic rainfall patterns change, there is absolutely no requirement that the rain land anywhere useful for our existing infrastructure or human habitation.

Yes, the water won't disappear, but if the effect is rainfall hits the ocean, or say, flood-prone regions even harder then it normally does, it's still going to be coming down somewhere not useful to us.

The problem is not that we can't solve these problems, it's that is is staggeringly expensive to do so.

Fresh water is created from the salty water by evaporation all the time.

Necessity is the mother of all invention, and with Necessity also comes scale, and with scale comes less cost...

Desalination has been expensive because it is not necessary, the second it becomes necessary I bet you will see the costs drop..

If nestle had to use Sea water to fill their bottles I bet they would have a cheap way to do it right quick

Indeed, and it's interesting to note that this natural desalination process also incorporates long-term storage mechanisms. Historically, vast quantities of freshwater have been stored in the form of snow packs and glaciers. However, in our changing climate, this storage is not occurring at the same scale as it used to. This could potentially exacerbate future water scarcity issues, making man-made desalination techniques even more crucial. As challenging as creating freshwater from saltwater may be, it's a puzzle we need to solve with urgency.

Make it so.
