But I love a good dog pile!
anthropogenic carbon dioxide constitutes only 3.4% of the total amount produced.
First of all, if you have a tight rope walker who's using a balance bar and the balance bar weighs 10lbs, adding .3 lbs to one end of that bar and not the other is going to have a very distinct effect.
Assuming your data is correct (and I have my doubts), you are still talking about 3.4% of CO2 which is being added annual above and beyond what the atmosphere can get rid of. That's tipping the scale.
Second of all, does this 3.4% include domesticated animals? Or are we talking just industrial and automotive output? Cows exist in numbers which would be unthinkable without our aid. They produce quite a lot of CO2 and methane. Are they NOT to be considered a man-made source?
Third, does this 3.4% take into account the REMOVAL of CO2 removers from the system? Cutting down rain forest reduces the amount of CO2 which is being removed from the system which increases the effect of what we put in.
So now, we have the tight rope walker with the 1/3 lb weight on one end of his balance bar and a couple helium balloons tied to the other.
Lastly, let's talk about your politics for a second.
What EXACTLY is the problem with reducing green house emissions?
Let's pretend that you are absolutely correct and that human CO2 has little effect on the environment. Further, let's pretend that even if we zero'd out emissions we'd still see a warming trend.
Okay.
So, what's the HARM in zeroing out emissions? What's the HARM in reducing the burning of coal, for example? What's the HARM in increasing free energy from renewable resources?
I hear a lot of people like yourself complaining about the "scam" as though there was some negative effect from reducing pollution and increasing energy independence.
So far the ONLY time I've had someone try and explain the "problem" they were saying that some people were making money off the change. As if there weren't people making money off the current system.
So, spin us a tale. What EXACTLY is the "worst case scenario" from cleaning up our act and cutting back on pollution?
