"Global Carbon Dioxide Temperatures"?
Please tell me you missed the words "levels / " from the middle of that...

And I didn't say we're too small to make a difference to the planet. I said we're not making that much of a difference compared with the massive differences that Nature itself makes.

A quick Google shows us: math.ucr.edu/home/baez/temperature/1.35Myr.small.jpg. Which shows a huge number of heating and cooling cycles. Beware of the scaling...
Disclaimer: I don't know how accurate it is, but it's from a .edu so I'd guess it's probably been at least a little bit researched.

And that graph says we're doing about right.

Also, remember that people keep calling a hundred years "long term effects". That's actually within living memory (well, within one lifespan). Even if something takes a thousand years to sort itself out that's still only HALF the time since Jesus is reputed to have been born- or about 12x the time since the 1st world war ended. Hell, it's only 20x the age of the Mini!

Anyway, the oh-so-evil oil (boo! hiss!) and other hydrocarbons (gasp!) will all be burnt or uneconomical to extract long before it does any incredibly serious damage.
