Humanity on average produces more carbondioxide than any natural sources, even volcanos.

That is inaccurate when an Indonesia volcano erupted in the early 90s, it released more CO2 than all of man's industrial output from 1800 to that point.  Perhaps you are speaking about each individual human, which from I understand generates about 2.9 pounds of CO2 a day, which for 7 billion humans would be a lot compared to the 0.5 to 1 billion cows, sheep, dogs, etc that exists.  Although insects have the far greater total terrestial animal biomass in the world which is difficult to estimate though some think it is as high as 50%..    Not to mention, the increases in CO2 is equivalent to adding 18 to a 70000 people in a stadium, CO2 is also a notoriously weak greenhouse gas compared to methane or water vapour.

Great rebuttal!
