Several sites I visited reported that in a gas engine 19 pounds of carbon dioxide were released for every pound of gasoline burned. Since CO2 does not rise in the atmosphere, and it is about the same weight as Nitrogen, it just floats around. Therefore, it would seem that a major source of atmospheric heating is from high altitude commercial and military jet plane exhaust emissions in the upper atmosphere. Does anyone know of a way in which total aviation gas purchases by commercial airlines can be captured as data input for calculations? Does anyone know the typical fuel consumption of various common types of commercial and military jet aircraft?

CO2, with a molecular weight of 44 is considerably denser at any given T and P than nitrogen (MW 28). But, when emitted from combustion, it will be at considerably higher temperatures than the surrounding atmosphere and will thus may have a lower density. At 372 degrees F, CO2 will have the same density as nitrogen at 70 degrees F. Above this temperature it will actually be "lighter" than air and will rise.

the protection rigidity consistently has preparation routines happening. I study there's a practise workout getting in this week, and perchance longer in Washington & Oregon and 2 alternative states contained in the crucial component to the country. that's meant to be like a simulated warfare, and the Canadian protection rigidity would nicely be preserving joint routines mutually. however, that's unlawful to buzz { low element intense speed run } a populated section and a suitable criticism might want to be filed on the close-est protection rigidity base. yet you want the range of plane and top time it surpassed off to record the document. If a pilot is got here upon in charge of a low element buzz he will be repremanded, extraordinarily if any homestead windows were damaged or different damage carried out. If the plane crashes into your position, do not problem because in a chop up 2d the homestead would not be there.

If I were THAT interested, I'd download the engine specs for the various jet engine types, then the total fleet numbers for the commercial, general, and military fleets. But that would be a LOT of work, especially if it were unpaid.

The only data i know is that aviation represents 3% of CO2 emissions.
Also, gases dont stay at where you release them, there are flows (due to change of temperature) that make then move, higher, lower, north, south east and west.

CO2 is heavy enough that it is used to smother a fire, and as soon as the CO2 cools down it will fall like a stone.

A lot less than if the same number of people it was carrying were
