One of the biggest problems we ‘deniers’ face is that few real facts are ever given by the AGW crowd. This is intentional, of course. For instance, they throw around labels like ‘green’ and ‘clean’ but never define them. It can be demonstrated that the atmosphere is ‘cleaner’ today that it has been in decades (in the U.S.), if not centuries (parts of Europe). How can something like CO2, necessary for life itself, be labeled ‘dirty’? It boggles the mind.

I’ve come up with (what I think is) a simple, understandable-by-anyone concept to explain why folks should stop being ‘afraid’ of Carbon Dioxide in the atmosphere.

Here’s line of thinking:

Question1:
What are the molecules that compose air? Name them in order of most-to-least abundant.

Answer:
Nitrogen, Oxygen, Water, Argon, Carbon Dioxide, and Other.

Question2:
If you take a random (or average) sampling of 10,000 molecules of air and assume that each molecule is worth a penny, how much would each of the different components of the air be worth?

(Note: 10,000 pennies is the same as $100.00. If you couch the discussion in dollars and cents rather than, say, PPM - folks will have an easier time grasping the numbers. Even a second grader understands completely the difference between a $20. bill and 4 pennies.)

Answer:
Nitrogen: $77.00
Oxygen: $20.00 (animals NEED this to live)
Water: $ 2.00 (this is the ‘real’ GHG)
Argon: $ 0.95 (that’s right, 25x the amount of CO2)
CO2: 4 cents (plants NEED this to live)
Other: 1 penny

Question3:
As you’ve heard, Humans have pumped MASSIVE amounts of CO2 into the atmosphere, yet it only makes up 4 cents of the entire $100.00 of the atmosphere. (That’s 4 CO2 molecules per 10,000 air molecules). How much of these 4 cents worth of CO2 has been added by Humans?

Answer:
1 penny. (280ppm to 380ppm)

Question4:
Let’s say that Humans had subtracted a penny’s worth of CO2 from the $100.00 worth of our entire atmosphere, instead of adding CO2. What would be the impact?

Answer:
Plants would be severly impacted and dying.

There are many more points that can be made. For instance, if we continue to pump out CO2, we can probably only push the concentration of CO2 to about 5-6 cent’s worth. Also, the threshold level of CO2 above which the MSDS suggests CO2 becomes a problem for workers is 50 cents worth (5000ppm). The amount of CO2 in our breath (using the $100.00 concept) is worth $4.5 of the $100.00 worth of air we exhale.

Anyhow, you get the idea.
Feel free to steal the concept, if you find it useful...
