The numbers are to small. But instead of actually debating that you attack me.
Because they are just too small by your declaration.
Very well. *sigh* Let me actually do the math and pluck your numbers apart.
CO2) is only about 0.038%
This number is completely useless. Small things can have a greater effect than you would suspect. Beginning with the fact that the little, little CO2 which you hardly deem worthy mentioning because it's just 0.038% is actually necessary for life. Which does NOT mean that too much isn't bad.
(CO2) levels in the atmosphere have risen by about 30% (280-370 ppmv) over the past 100 years.
Carbon Dioxide accounts for about 4.2-8.4% of the greenhouse effect
So, how large is the Greenhouse Effect? It's commonly estimated at about 32 degrees Kelvin and since you posted no other number that's the one I'll go with. So 5% of 32 degrees is 1.6 Kelvin. An increase by 32% would then cause a rise of temperature by 0.51 degrees. Isn't that far below what we observe, is it? Note that I used a low number from the 4.2-8.4 intervall. Obviously this is a rough estimate, I miss a couple of positive and negative feedbacks loops, but using only the two numbers you posted GW is very plausible.
Humans can only claim responsibility for 3.4% of the Carbon Dioxide (CO2) emitted to the atmosphere annually
True... and what does that tell us? Does that mean the CO2 we output is not enough in tons for the additional tons that appeared in the atmosphere? But it is, that's a simple checking of the numbers. Maybe you mean it's effect on the natural balance is too low? Let's try that.
Let F(t) be the amount of CO2 in the atmosphere at time t. We can model the change by
F'(t) = O(F,t) + H(F,t) - A(F,t).
Here N is the natural output, H is the human output and A is what is absorbed or turned back into O2 and C.
Now, your numbers claim
F'(t) = 1.034 * O(F,t) - A(F,t). And here we stop because we can do nothing at all without studying A, i.e. the CO2 sinks of the world in detail. Of importance is here mainly the dependence of A and F,t. And in similar equations of that form occuring in nature there are very different forms of A's occuring. Easy ones would be
A = const. (example being human breakdown of alcohol in bloodstream)
A = k*F, k being a positive constant (population curves)
In the first case the excess would simply accumulate in the atmosphere, while the second one would support your point.
This shows that this number alone is worthless and the fact that you failed to realize it shows that you don't know what you are talking about.
