What? Absolute humidity at saturation increases with temperature (at fixed pressure). At 100 C (and 1 bar), the air becomes entirely water vapor.

Oops, I had it the wrong way around.

Generally, though, hotter weather means more water evaporates, and regardless of whether the air can hold more or less water, over time the same amount that goes up will come down, meaning total precipitation will increase as the earth gets warmer.
That doesn't mean that this increase will be uniform. The rain may very well come in Sahara, Arabia or Central Asia.

That is incredibly backwards. Which is why when the temperature drops the water literally comes out of the sky.

Yep, you're are right, my bad.
Higher temperature air has less capacity to carry water, 7% less for every degree Celcius IIRC. So there could very well be a link.
EDIT: Nope, I had it completely backwards, which makes much more sense too. Colder = less capacity for water. I need a drink. Can't delete my misinformed comment unfortunately.
