Do fire works add co2 into the Atmosphere, because if they do then theres tens of millions going off right now. In tens of thousands of them going off on my street tonight.
Happy fourth of July!!!

I see your point. What about a volcano going off with fire sprewing. Looks like trillions of fireworks going off there.

No, they don't.
The products of fireworks are particulates. If they could somehow get up in the stratosphere, they would actually cool the atmosphere some. But since the smoke from fireworks is confined quite close to the ground, it falls to the ground pretty quickly and thus has no real effect.

Which is why after Bonfire Night on the 5th November here it is often foggy the next day.

No Real Effect? I beg to differ. The smoke on our block and the whole area was so dense you could barely breathe. Some of the bombs going off knocked the pictures askew on the walls.

There is no large-scale effect from fireworks simply because of the relative amounts of carbon burned worldwide. They present a tiny fraction of it compared to petroleum products, coal, and wood being burned worldwide on a daily basis.

All the carbon in those fireworks started out from a plant source, so it originally came FROM the atmosphere. Burning it just completed the cycle.
Put that in your pipe and smoke it!

Yeah but burning them releases the carbon, previously locked away in the plant, back into the atmosphere.

No real effect on the global temperature was what I meant. Particulates in the lower troposphere get rained out quite quickly. Only if they get all the way up into the stratosphere (as in a large volcanic eruption) do they hang around long enough to have any real cooling effect.
