Thank you for the marvelous graphs, lol.
But in all seriousness, if you look closely at a graph comparing greenhouse gases and temperatures over time, you'll notice that the greenhouse gases FOLLOW the temperature. That's right, the planet gets warmer first, then we find more greenhouse gases! Alright, so what does this mean for us? The planet is getting warmer, no reasonable person would dispute this. This evidence also suggests we are not the only cause. The real question at this point is how much are we contributing to the whole deal? I'm not smart enough to know. While we are almost guaranteedly helping this along, evidence suggests that maybe not as much as you might think.
