I've never had it fully explained to me yet (but maybe Al Gore can produce the explanation - he does that well, with glib answers for most things that are difficult to explain) .. how Carbon Dioxide, which is a heavier-than-air gas .. can climb to sufficient stratospheric heights, and in sufficient quantities, to act as a global warming agent .. ??
Note the simple explanation on the following site .. and I quote ..
CO2 gas is 1.5 times as heavy as air, thus if released to the air it will concentrate at low elevations.

Now, I notice on the following, MI university, glib GW site .. no mention ANYWHERE of Carbon Dioxide being 1.5 times as heavy as air .. and concentrating at
LOW ELEVATIONS .. ??

Maybe I missed something in science class?? .. maybe it was when I was asleep?? .. or maybe when it was I was too busy admiring how shapely, and how long, the legs were, on Miss Snorks .. ??
