I'm not talking about climatic change; I'm talking about an increase
in humidity.  And *local* humidity, not global.  Greenhouses gases
create chemical reactions.  That's qualitatively different from simply
pumping moisture into the air, even setting aside the matter of which
would create measurable results more quickly.

For example, the south end of the San Francisco Bay Area, where San Jose 
is located, is surrounded by mountains on three sides.  This bowl-like
landform catches and holds smog at times during the summer months due to
temperature inversions and a lack of wind.  It doesn't strike me as un-
reasonable to wonder whether, in a scenario with thousands of cars pumping
out water vapor say after day, that vapor might collect to the point where
local humidity would be noticeably affected.  Not catastrophically, but
noticeably.
