Certain lakes in Africa reported to belch CO2 from rotting veg in the lake bottom. Sudden release, the CO2 drifts down the lowest valley out of the lake, everything dead down wind. Cows, dogs, people, birds. The CO2 is rapidly taken up by growing plants and cleared from the air. Big mystery until solved by investigations.
Stage and movies productions, low mystery fog, produced by dry ice= CO2. Heavier than air.
Surface growing plants, land and sea, take up CO2 instantly when in contact. CO2 is basic plant food. 85% of Earth covered by oceans. Land plants minor users of CO2 in comparison to the sea plants and buffer systems.
CO2 atomic wt. -44. O2 -32. N -28. H2O -18. Clouds(water vapor) on a hot day can only get up to the mid 20,000 ft.
Fuel burned above 30,000 ft (jet fuel) main way CO2 gets into the upper atmosphere in large quantities. 2-5 tons per hr per engine. 3.66 tons of CO2 /ton of fuel burned. Settles down slowly.

And your question is?

===================

“CapNemo” likes to go to all the global warming questions and paste in a statement pooh-poohing the threat. His statement is misleading and incorrect.

He says it’s only increased by 1 degree (F) in 125 years. This is a misleading number, because it is a global average: land and sea. We don’t live in the middle of the ocean and that’s not where the polar ice caps are melting. The temperature change over land surfaces has been twice that, and most of it in the last 40 years.

He says, “The average temperature in Antarctica is 109 degrees below zero.” If you go to his source, it says, “Temperatures reach a minimum of between -80 °C and -90 °C (-112 °F and -130 °F) in the interior in winter and reach a maximum of between +5 °C and +15 °C (41 °F and 59 °F) near the coast in summer.” OK, now the observation that the caps are melting makes more sense. It melts at the coast, in the summer, DUH! (Note by the way that his average number (-109) is only 3 degrees lower than one of the minimum numbers. I wonder, what kind of math did he learn?)

Then he says, “Back in the '70s all the hype was about global COOLING”. All what hype? I was around then. I don’t remember any hype. And if you go to his source, it says, “This theory gained temporary popular attention due to press reporting … The theory never had strong scientific support”. He tries to mislead us, by implying that a temporary flurry pf press reporting is comparable to what we are seeing now and that some hype without scientific basis is somehow similar to a consensus within the scientific community about global warming.

The truth is that those 2 degrees are HUGE in the scale of average weather change. But the real problem is the speed of change and that it's accelerating. Scientists are predicting a temp 4 to 8 degree (F) increase over the next 75 years. “This may not sound like a great deal, but just a fraction of a degree can have huge implications on the climate, with very noticeable consequences." (http://www.channel4.com/science/microsites/U/ukweather2080/5_predicting.html ). Yes, scientists predict, that's their job. They've gone to school years more than we have and spent their lives studying this stuff. This representrs humanity’s BEST GUESS at where this is all going. Of course, you can believe it snows in hell, or any other stupid thing you want. No one can stop you from believing what you'd rather hear, than what is the most probable outcome.

The link between CO2 and global warming is undisputed at this time. The amount of CO2 in the atmosphere has increased by more than 50% over the last 115 years (250 to 381 ppm, http://awesomenature.tribe.net/thread/fcc70c8b-be7e-489b-85f7-6c6c08031c65 ). In the last 30 years, it increased at a rate 30 times faster than at any period during the last 800,000 years. In other words, this change is totally unprecedented. (http://awesomenature.tribe.net/thread/fcc70c8b-be7e-489b-85f7-6c6c08031c65 ). What else is totally unprecedented about the last 115 years? Industrialization and the population explosion. Duh. This is not rocket science; it is simple arithmetic!

"If Bert Drake is right, the good news is that, within the foreseeable future, Maine residents will be able to stop banking their foundations and to store their down parkas and snow blowers in the barn permanently. The bad news is that a lot of those barns will be underwater" (http://awesomenature.tribe.net/thread/fcc70c8b-be7e-489b-85f7-6c6c08031c65 ). Yes, this is opinion. Who is Bert Drake? He's an SERC researcher who's been studying this for 17 years. If we aren’t going to believe our scientists, who then shall we believe??? Oh, I know. Let's believe CapNemo!!!

If global warming wasn't a real threat, why have 178 nations ratified the Kyoto Protocol to limit CO2 emissions? Why are the US and Australia the only two holdouts among the industrialized nations? (http://environment.about.com/od/kyotoprotocol/i/kyotoprotocol_2.htm )

CapNemo’s statement reminds me about the frog in the pot on the stove that doesn’t move as the water gradually gets hotter and hotter. From this seemingly insignificant 2 degree change, we’ve already seen enormous consequences. (http://www.davidsuzuki.org/Climate_Change/Impacts/) How much hotter does it have to get for some people to wake up and face the music? And in the meantime, while you’re pondering all of this, be sure to check the dates on people’s references. Things are changing so rapidly that older information is no longer useful.

I think that if the only source of CO2 in the atmosphere was from the Jet engines then by your argument wouldn't that mean that mean that all of the CO2 would then move to the surface of the earth because it is heavier than air. This would then mean that if we took the concentration of CO2 in the atmosphere then it should be 0. But this is not the case. There is still CO2 in the atmosphere. So i don't think that CO2 would move to the surface, maybe wind might play a role?

Actually the temperature of the earth has increased less than 7/10 of 1 degree (C) from 1880 to 2005. That is an increase of about 1 degree (F) in 125 years. You may choose to believe that is global warming or you may not. Source: http://data.giss.nasa.gov/gistemp/2005/2005cal_fig1.gif There are numerous charts all over the internet showing the same. Some say that 1 degree is enough to impact the global climate, others say it's not. Most proponents of global warming think the earth's temperature has risen much more than that and don't even know that it has only risen by 1 degree. But the charts do not lie as do the proponents on both sides of this issue. The average temperature in Antarctica is 109 degrees below zero. Source: http://en.wikipedia.org/wiki/Antarctica#Climate It seems to me 108 below (one degree warmer) is still pretty cold and not enough to melt anything. But there are those that say it will.

Back in the '70s all the hype was about global COOLING and another ice age was coming. I remember that they blamed pollution for that too. They said that all the pollution was darkening the skies and not as much sun was coming through so the earth was cooling off. It took many years to discover that they were mistaken and it was all just hype. Source: http://en.wikipedia.org/wiki/Global_cooling So when someone says, "the sky is falling" don't believe everything you hear on either side of the issue. There are Spin Doctors galore out there.

Most of the time people will form an opinion and not really be informed about the subject with which they become so opinionated about. So it's best that you not form your opinions from other's opinions, (as in this forum) but on the facts presented. (Many do not provide any proof or links to prove their point, just their opinion.) With that said we do have a responsibility to do our part by doing whatever is within your power to keep our planet alive and well.

I hope that helps...

Possible answer to the sudden release of the CO2 . Take a coke and put salt in it the CO2 will come out rapid.Possible the CO2 was in the lake and a large shelf of salt broke off and flashed the CO2 off.
The CO2 from high altitude aircraft will fall like a rock. When measuring CO2 it is so heavy that it could smother u ,so look for it on the ground,not up in the air.

Is there a question in there?

As indicated by others in response to your previous question, CO2 does not simply sink by virtue of its atomic weight. The kinetic energy of the gas particles in the atmosphere is enough to overcome the differences in weight.
