Global warming has become a major problem for us. Apart from CO2 as a major cause of global warming , I would like to point out that natural Air is being used as a compressed air in the factories , car tyres etc.etc . Definitly like other natural resources air is also in limited quantity. As per survey 600millions vehicles are being used in the world. It means 4x600millions tyres have been filled up with the compressed air. Definitly so much of qty of air must have been reduced from the atmosphere resulting reducing the air density. Therefore I would like to ask scientists whether the abundant use of compressed air which is not being released to atmosphere may play a role in global warming in future?

Insignificant. Do you have any idea how much of our atmosphere evaporates into space EVERY DAY???
You Global Warming believers worry about the strangest things!

Time to reach for the calculator...
1 - VOLUME OF ALL TIRES
> Number of vehicles in the world = 1.3 billion (I think the figure of 600 million may be just cars)
> 6.5 billion tires in the world (I've allowed for a spare tire in every vehicle)
> Average outer diameter (o) of a tire = 700mm (a top side estimate), larger than average car tire to allow for commercial vehicles etc
> Average inner diameter (i) of a tire = 500mm (a top side estimate)
> Average width of a tire = 200mm (a top side estimate)
Volume of air in one tire = 500 (Ïro² - Ïri²) = 94,285,710mm³ or 94.3l³.
Multiply by 6.5 billion = 613bn l³ or volume in all the tires in all the world, same as 613 million m³.
2 QUANTITY OF AIR IN ALL TIRES
> Volume = 613mn m³
> Normal atmospheric air pressure = 14.7psi
> Assume average pnuematic tire = 30psi
At normal atmospheric pressure the volume of air is 613mn m³ , inflated the volume of air is 1251mn m³. Therefore the amount of extra air required to inflate all the tires in all the world is 638mn m³.
3 COMPARE THIS TO THE VOLUME OF ATMOSPHERE
> Inner diameter (i) = 12,756,000m
> Outer diameter (o) = 12,766,000m (almost all the mass of atmosphere occurs within the first 10km)
Volume of atmosphere = 4/3 ro³ - 4/3 ri³ = 2.773980²¹ - 2.767466²¹ = 0.006514²¹ = 6,514,000,000,000,000,000m³ or 6,514,000,000mn m³
6,514,000,000mn ÷ 638mn = 10,210,031.
4 SUMMARISE
The amount of air in all the tires in all the world is approximately one ten millionth of the total volume of air.
5 CONCLUSION
The proportion is so small as to have a negligible effect.
6 FURTHER INFO
Taking air out of the atmosphere and storing it in compressed form causes the gases within the atmosphere to expand in order to maintain equilibrium. This expansion of gases (including the greenhouse gases) reduces the incidence of global warming.

I think you just came up with a solution for Global Warming, we should inflate our tires with CO2, that way it'll free up the air in our tires and get rid of the CO2 in the atmosphere :o

Your premise may be a Yahoo! answer record for convoluted thinking. I'd like to keep in step with you by offer the suggestion that we invent something called synthetic air for use in filling our tires. By the way, you forgot all of those darn bicycles.

Interesting. A little crazy, but interesting.
