Just one example is cited below...unless you want to tell all of those idiots at NASA that they're wrong. All those engineers and rocket scientists are pretty dumb.

So, assuming you're willing to graciously admit that CO2 can affect the climate, take the following into consideration: there are 7+ BILLION people in the world; they have 1+ BILLION working automobiles, and every single one produces 4.7 metric TONS of CO2 every year; the vast number of military and civilian jets in the world that fly every single day; the tens of thousands of factories in the world; and the reduction in CO2-absorbing trees and plants from the growth and spread of the population. With all of that, uh, yeah, it's very easy to see how the global population of earth could affect the atmosphere and, by result, the climate.

I doubt any of that will make you change your mind, though. Because you don't want to. No amount of evidence in the world can make someone believe something they simply don't want to believe. They'll simply discount the evidence, no matter how strong or numerous, or discount the source of the evidence as biased, even if it's very clear and likely that it's not.

I havent seen any data in this arena, but would be interested if you could pm me or post those numbers. This is a serious inquiry because I have failed to locate any of that info.
Thanks Gator

I thought this article was interesting, although its but one single source of info and I'm just putting it here as one anecdotal answer to your question ...it uses 450 ppm as a generally accepted benchmark that we need to not rise above.

https://www.climatecommunication.org...tialaction.pdf

Excerpt: "In order to stabilize CO2 concentrations at about 450 ppm by 2050, global emissions would have to decline by about 60% by 2050. Industrialized countries greenhouse gas emissions would have to decline by about 80% by 2050."
