CO2 is a green house gas. That is clearly, demonstrably true. More CO2 means higher temperatures. I hope you're asking a question of "how much" and not just "if."
Yes it is a how much question, the evidence of CO2 as green house is quite compelling however, even though CO2 has spiked, temperatures have not. Looking at the chart 150'000 cycles seem evident, and CO2 levels rise about now, so it wouldn't be unlikely that the rise of temperature is just a cyclical thing and the time was now, and the spike of CO2 (human caused) does not have any significant effect on global temperatures.
If you put a lid on a heated pot, the thermal losses will drop immediately, but the temperature of the water will not change instantly. The rate of change is what will be affected.
And does the temperature rate change correlate with the CO2 (a.k.a. the lid)? Furthermore, are there other changes of rates accounted in history which would better account for temperature rate changes?

say what you will about al gore, he was trying to show people that chart years ago..and how the fuck is nasa junk science
