I'm not sure why you think all the water on the earth's surface is going to vanish.  Water is warmed and evaporates into the atmosphere and comes back to earth all the time.  A warmer earth doesn't mean all the water suddenly disappears.

Life can exist with a very small amount of water and there is still a lot of water inside the earth.
