I thought "scientists" were behind the belief in global warming. Even the simplest student should be able to tell from those numbers that CO2 is irrelevant in the warming of the earth.

The fact that the numbers are small or that the amount of one thing is tiny in comparison to other things has nothing at all to do with whether or not it can have a large impact. That's determined by other factors. If you don't know those other factors, simply making an assessment by saying, "Them number's are soooo small; they can't possibly have any effect on something this big" is itself unscientific and unthinking. See how many molecules of botulinin it takes to bring down an organism billions and billions of times greater in terms of numbers of molecules. There are a lot of other things involved. In the matter of anthropogenic GW, it turns out that even doubling, tripling, or quadrupling the total amount of atmospheric CO2 wouldn't have effect past a certain (small) point).

Didn't you just negate this "The fact that the numbers are small or that the amount of one thing is tiny in comparison to other things has nothing at all to do with whether or not it can have a large impact." with your concluding statement?

That's part of the whole argument against CO2 increases causing global warming. Since other factors ARE involved simply claiming that CO2 increases as the main cause of GW, as the GW alarminsts are now touting, cannot be the sole cause of GW.
