are we going to run out of wter?

Answer 1

There is no evidence of any meaningful reduction in earth's water supply. Pure water just won't be so easy to get, since we've grown accustomed to wasting so much of it. God provides lots of it continuously by distillation in the water cycle, and distributing it in aquifers so it's available nearly everywhere on earth just by digging a hole in the ground. If global warming or something else changes that, it will most likely change the distribution, not the quantity. Rainfall patterns may move away from areas which traditionally receive abundant rain, toward areas which traditionally receive little. Even if nothing changes, many areas will run out of easy pure water simply because they exhaust fossil water supplies.

Answer 2

No, it will just be harder to get.
We have the technology to remove the salt from seawater to make it drinkable. It just takes a lot of energy to do it but it is possible.
The biggest problem isn't drinking water though. It is irrigation water for our food crops. A warmer climate (whether man or naturally created) could cause less rain to fall which affects lake levels, river flows, mountain snowpacks, etc. This in turn creates a dearth of water to use on crops to grow our food.
That's why there is so much talk about global warming. Even if we're not completely to blame (maybe its mostly natural warming), we are still affecting our planet in negative ways.
Hope that helps.
