On: Ask HN: What's a promising area to work on?

Can you expand on what you mean by this? How will water cause a war? Do you mean freshwater access?

[al_chemist → johnmorrison]

Global warming will melt ice caps and flood the world. Or global warming will evaporate water and dry the world.

One thing is sure. Global warming, water and world war three. /s

> flood the world

No, there isn't nearly that much water.

> will evaporate water and dry the world

How would this work? Either the water is on the ground or it is in the air, neither case is a dry world. Where would all the water go to "dry the world"?
