Speaking of CO2, has everyone seen the recent issue of Science News with
the photo of the open beaker of liquid CO2 sitting in the sand at a couple
of km underwater?  This was an article about a possible solution for
global warming: rather than letting greenhouse-gases escape from industry,
liquify them and release them deep underwater where the pressure is
naturally high enough to maintain their liquid state.  (Sounds a bit like
dumping industrial waste in the desert!)  The article mentioned that the
rolling globs of liquid CO2 attracted curious fish.  From the fishes
viewpoint, CO2 is "naturally" a liquid, eh?
