A couple things on that
A)I'm brushing over the French vs American thing because it's growing irrelevant (and Americans are more ethnically diverse)
Studies on heart disease incidence are stratified by race, and it's the same thing even if you compare white people in America and in France.

B) I didn't say anything about the heating of the middle ages. I haven't researched it. There is consensus about volcanic activity, it's mainly due to cooling because the smoke blocks out the sun. the carbon emissions aren't as effective or consistent. If you want me to research the warming of the middle ages, I might do it but I don't really care to take the time to at this time. You're citing wikipedia. Come on now.
and C) well unless there is some sort of major global disaster, yes, according to Darwinism they will remain steady. It would take extremely massive increases/decreases in populations to make a footprint. since we're talking about CO2 emissions coming out that would have to be a global disaster, otherwise it's just animals reducing the populations of other animals via predation which leads to an increase in the predatory organisms. You trade prey for predators essentially. Thus it stays relatively steady.
So in other words, we're supposed to believe that our mass breeding of COWS has contributed significantly to the human carbon footprint? What about all of the buffalo that were killed out west in the late nineteenth century? Shouldn't that have reduced CO2 levels significantly? And why can't relatively minor perturbations in the balance of phytoplankton/zooplankton or photosynthetic bacteria/aerobic bacteria cause global warming when their biomass is many many times larger than cattle's?

Once again, scientists generally don't agree on how exactly fluctuating volcanic activity can affect climate. Even the same blog you quote says as much.

And there is still no real scientific explanation in how ice ages occur. They can't all be explained by volcanoes.
1) fair enough, if we were discussing the difference in French/Americans I would press further, but its an irrelevant conversation that's railroaded off point
2) I never said any of that. You'd have to present some sort of statistical data because I don't know how much more we've bred cows. One could argue that that contributes to warming, and then you have a philosophical argument about whether humans are responsible, which indirectly they kind of are. As for the extinction of certain buffalo, again it depends on statistic, of which I don't know. But what I do know is that that was during the period of the beginning of the industrial revolution.
I have no qualms in admitting that animals are largely responsible for CO2 output, I will say it's true, even though I don't know it as a fact (and if someone presents me with evidence that supports it either way, I will accept that evidence unless better evidence presents itself saying otherwise), but you can't ask me to make professional readings of specific animal populations and their subsequent extinctions leading to changes in the carbon footprint. I have my doubts that one subset of one species of an animal has a significant monopoly or "leading percentage" on carbon emissions.
Further, you're missing the point on the small organisms. There's only ways such organisms can increase in population and thus their carbon footprint 1) outside causes, but only a massive disaster would lead to an exponential or noticeable change and 2) other aerobic agents being the victim of predation; thus the prey is decreased and the predator is increased, counteracting each other. I don't much about cells but you have to present me a certain case or reason why they are increasing,
because for the last time saying animals x,y, and z contribute to carbon emissions is a meaningless statement. If you're going to say an increase in emissions on their part is responsible, you have to prove it by showing their increase in population and thus emissions, not just say it could be happening
3)true, but what we do know is that the gases they release are only 1% of the carbon emissions and greenhouse gases per year that humans release per year and smoke cover acts as a cooling effect. The lack of activity in the last 100 or so years doesn't seem to show any correlation with the current trend.
Further, the link you stated doesn't seem to say what you say it said. It basically says there doesn't seem to be a strong correlation outside of a lot of activity contributing to a cooling effect because of the smoke cover and a lot of activity accumulating carbon emissions, but only that could be done over an excruciatingly long amount of time.
Volcanos just don't seem to be having an effect on the current trend right now.
