Any water you capture will just be sent back into the air later. Think of what y...

The important thing is the speed of capturing and returning the water to the air, not only the fact that it will be eventually returned.

When we change one or both of the speeds - the balance shifts, and the effective humidity of air changes to new stable value.

But there is a feedback loop - the faster you take the water, the slower you can get it.

And the more water is returned the faster it ends up in the air. My estimate from wind speeds is that everything will stabilize within 2 days.

i.e. taking water from the air will have no impact. See: http://news.ycombinator.com/item?id=4816580 where I expanded on the topic a bit.
