How about C + O2 -> CO2. Carbon is not diatomic.
But what does this have to do with microscopic amount of matter being added to the Earth's mass? What effect do you believe meteors have on climate?
Your stupidity is starting to hurt my head. Let's start over.
1. The Earth is not a closed system, nor is its atmosphere.
2. The addition into the atmosphere does not constitute a closed system mechanism.
The purpose of my chemical equation was to highlight the second point. Human activity adds CO2 to the atmosphere by a chemical mechanism. Chemical mechanisms also remove CO2 from the atmosphere.
As for your babble about matter-energy conversion, you are barking up the wrong, and an irrelevant, tree. Matter and energy are, for all purposes relevant to this discussion, are the same. If the atmosphere were a closed system, then neither matter nor energy would enter it or leave it. If the Earth were a closed system then neither matter nor energy would enter or leave it.
I made it quite clear that I am contending that the Earth is a closed system with respect to carbon dioxide. If you can't cope with that, you need a little more experience in the real world.
The Earth and it's atmosphere are the system.
I never brought up any mass additions. You guys did. I simply pointed out that they were as inconsequential as it is possible to be.
YOU brought up the equivalence of matter and energy. That equivalence is utterly irrelevant to climate change and is many orders of magnitude more inconsequential than our daily collection of meteor dust.
I've already asked this of SSDD. Let me ask it of you. The Earth's addition of meteoritic mass over the planet's entire 3.5 billion years is a factor with 18 zeroes after the decimal place (quintillionths). We're actually examining a process that has only been going on for 150 years and we can say we're interested at most in the next few millennia. Further research indicates that the incoming matter includes almost no carbon whatsoever and so is even
more irrelevant to the process under examination.
So,
what is the difference between the abstract construct of a closed Earth system and the real one? If you don't want to talk about that one, how about ANYONE here identifying a truly closed, real, extant system; no energy in or out, no matter in or out.
And do try to tell us that you misstated the CO2 reaction as a test.
