One of those jets uses more fuel on a flight than a year of driving does for most of us—yes, I know that we’re talking jet fuel versus gasoline.

So what’s the difference? Jet A is basically good kerosene, which is cheaper to produce that gasoline. We just took a trip using one of our “family’s” Cessna Citation X jets, and while it may use a bunch of fuel, it sure it a nice way to travel. Go when you want, and no bother with TSA.
The distance between Louisville and Buffalo is 460 nautical miles. A Cessna Citation Bravo business jet making that trip today would experience, at flight level 450, a six knot tailwind, which is very mild. The required fuel to takeoff, climb, cruise and descend would be 1,680 pounds of Jet A. Using a conversion rate of 6.75 pounds per gallon, that works out to about 250 gallons, or about twelve tank fulls of gas assuming a 20 gallon tank.
Do “most of us” buy gas once a month?
Cessna Citation X uses $800 of fuel per hour. Seats 8
I would guess that it stands to reason --- dumping large concentrations of CO2 at altitude (in the article 31,000 ft elevation was mentioned) would be vastly more significant in recapture of IR radiation (transforming that into heat) that otherwise would be escaping back into "space" in IR spectrum, than the same amount of CO2 would be nearer to the ground ---where in seasons of green growth, significant amounts are taken up by plant life.
Where are the computer models? We must have computer models. [a.k.a clown 'science']
Next time your at an airport get a whiff of that jet exhaust. It's a lot nastier than your car. Then watch them leave from behind and notice the brown cloud.
