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?

That's because Algore invented the Internet and his primary focus is on untruths.
I went up in a glider once and was surprised by all the noise - wind noise as the glider rushes through the air at ~ 100 mph(?) and all sorts of banging caused by minor turbulence on the airframe.
No,No,No!
Just tax the he!! out of watering to save the earth!
If we quit watering lawns then watering of lawns can't be taxed!
NO, it not convection, which is sufficient but not necessary cause. Brownian motion will mix the gases in the absence of convection, wind, turbulance, etc.
If you put the gases in a chamber without convection, etc., they will mix.
>> Anybody can say anything on the internet, but that doesn’t mean it’s true.
You should also factor in the circulatory effects of water vapor, air temperature, & pressure currents.
It certainly can't compare to the noise experienced by one in a P-51 at 250 kts when removing their DC headset in flight.
My ears will never be the same....
Yes, I know. docbnj had a reasonable answer to the original question posted at #35. My point was only the the supposed "best answer" to this question from the linked site appeared to me to be wrong.

Once you become deaf, the noise level seems to abate quite a bit. ;-)
Your consumption of the "drink" is obviously below the set standards created for our own good.
You need to go and quench your thirst via the koolaid and then perhaps you will start talking in lockstep. LOL!
Lake inversion is also a very dangerous source of CO2. I learned all about here on FR!

If man made CO2 is the culprit for today’s global warming, what caused the global warming that melted the glaciers that were covering most of North America 20,000 years ago? Also what caused the global cooling that caused these glaciers to form? Obviously there is some other very significant mechanism other than man made CO2 that causes massive global climate change.
Huh? I appreciate your conveyance with your experience in a glider.
I enjoy hearing of experiences I have not had the pleasure of doing myself.
Especially when it comes to aircraft.
I'll put you on my "lucky dog" list! :- )
Brownian Motion is a result of a molecular-scale twiddling around of thermally vibrating molecules. By contrast, convection happens (sometimes quickly) with rather large volumes of air.
Thunderstorms are a great agent of convection. The typical thunderstorm cell moves air from near the surface up to the tropoause and back, at rates measurable in meters per second. One of those cells last only some 45 minutes, but there are estimated to be thousands going on in the atmosphere at any one time.
There are gentler forms of convection, also going on. Air rises at the equator, for example, and sinks in the Horse Latitudes (about 25-30° north and south of the equator). This goes on constantly, because of differential heating at the Earth’s surface.
The lowest level of the atmosphere is called the troposphere from the Greek root meaning to tun, because it is always turning over. For Brownian Motion fans, I am sorry to say that this is a lot more motion than Brownian Motion ever was dreamed of accomplishing.
Good luck,you’ll need it.Everyone knows flight by intelligent design requires two rotors and much spewing of hot gases to overcome the gravity caused by the flatness of the earth.
Reading and doing research on where CO2 comes from, most is, from what I read, from volcanoes. As an example one small volcano in Pozzuoli, Italy (Solfatara) flows 1,500 tons of CO2 into the air every day and this volcano is really small as compared to Yellowstone and other large and super volcanoes. If one extends the flow of such a super volcano as Yellowstone then Yellowstone should flow several hundred thousand tons per day. So if one counts all the volcanoes and other sources of CO2 the CO2 emitted by humans is so small that it is not even in the same ballpark. But then Algore and the other lefties care less they just want to put us all in the camps.
Well like Rush says, where do liberals get off saying that there is only one perfect climate and that we are ruining it? The climate constantly changes, it is never the same. It goes in cycles, cold, warm, cold, warm. Liberals in their arrogance think they can control it by dictating to other people, keep the climate one set way because they think they are Gods but it`s ridiculous. We can no more control the climate than we can control the sun.
Seems a bit more than “slightly denser”.

“Nature puts our roughly 90% of the CO2 on the earth while all of human activity contributes approximately 10%.”
I agree with Gore; we must redesign nature and bring the CO2 level down to the human contribution level.
