Let's see if Al Gore can answer this one (Letter To The Editor)

In the matter of "greenhouse gases," carbon dioxide is, shall we say, the gas du jour. We should surely be up to date and knowledgeable on CO2, which is said to be forming a kind of blanket which prevents the escape of all this global heat to outer space.

So can I table the question: How does the carbon dioxide get up there?

Carbon dioxide is one-and-a-half times heavier than air. I doubt even Al Gore would try to challenge that. So why doesn't it just lie around at ground level like autumn mist, and, of course, choke us all to death?

I bet it's a peaceful and quiet bast to experience.

The canopy turns the cockpit into a greenhouse in short order once it's closed. That's great in the dead of winter, but this time of year it quickly turns into a clam bake. The cure is opening all the fresh air vents, but that makes for a lot of wind noise, especially if you are flying much over 60 kts. Otherwise, it is quite peaceful.....
