We are being repeatedly told, mostly by government agencies, that manmade CO2 emissions are responsible for dangerous global warming.
Is it?
Well, the first question to be answered is how much of it is there?
The answer is “very little.”
When we look at the composition of air, we find that it is made up of two main components – nitrogen and oxygen, at about 78% and 21% respectively.
You don’t have to be a rocket surgeon to realize that this adds up to about 99%
Now you may be asking at this point – ” wait a sec – I thought that we were being polluted to death by CO2.”
Well, you are asking a very good question. Because even of the 1% left over that is not nitrogen or oxygen, most of it is argon (about 0.97%). Carbon dioxide then at last gets a look in at about 0.03%. You’ll notice in the pie chart below that water vapour is 1% – this will vary according to the local climate – tropical, arid, etc.
Look at the tiny slice (the red line) that is CO2.
That’s it – that’s all there is. A tiny amount.
Because of all those zeros, it is usually expressed as parts per million, somewhere between 300 and 400. In other words, for every million molecules of air only a few hundred are CO2.
So all in be billions and trillions of dollars that are being spent around three world on “research”, all the commission targets, all the green schemes, every carbon tax and trading scheme around the world, every conference junket in exotic locations, every item of news devoted to it, and all the spruiking from the ALP and the Greens are about a gas whose concentration is so small that we have to express it in parts per million.
And make no mistake – when you are expressing something in parts per million, you are speaking about something that is present at “trace” levels.
So there is hardly any CO2 present in the atmosphere anyway.
So how could a gas present in such miniscule concentrations be influencing our climate?
That’s what I’d like to know. Tomorrow we’ll look at why people say it does, and whether these explanations hold up.

You don’t know what happens if you remove all CO2 from the atmosphere? I take it you have no science education then. When CO2 reaches 200ppm life on earth starts to diminish. When it drops to 150ppm all life on earth ceases
what happens if you remove all the co2 from the atmosphere? Does the earth not cool dramatically? Then once anaerobes become the dominant mass on earth methane would warm increase temperatures? IF you call yourself science literate then why would make the correlation between low concentration and no warming? You flaccid argument of “there is not enough of it in the atmosphere to make a difference” is rendered invalid from the sheer fact that it CO2 helps keep the atmosphere warm. If you removed the small concentration then temperature would change. Doesn’t that make it very important?
