DG, you are coming across as a tinfoil hat-wearing, raging lunatic. Is that what you're aiming for?

(2) When their models can predict future climate patterns, then I'll take notice.
(1) You are free to do your own independent reading and research to test the veracity of the temperature anomaly data. I have, with a fair degree of (admittedly non-professional, casual, hobbyist) rigour. The chart is a fair and reasonable reflection of actual temperature anomaly over the time period shown. Whether you believe it or not has no bearing on the relative strength of the data.
(2) You'll think about the future when we can predict the future? That seems more than a little idiotic. I guess you mean you'll pay attention to the "so-called AGW problem" when the models can predict the future? I can sort of follow you down that path, to a degree... Sort of akin to "when somebody can prove god's existence I will believe in god." Most people (religious or spiritual ones, anyway) don't apply that standard to belief, but happily apply it to AGW. Personally, I consider the AGW hypothesis unproven and (currently) unprovable, which isn't the same as believing it cannot be true. One way of looking at it would be to adopt Pascal's wager (about the existence of god) to AGW; you might not be sure, but the benefits of belief may be long-lived with widespread effect, and may substantially outweigh its costs, whereas the benefits of non-belief may be short-lived and selfish. I'm sitting on the fence until I can decide for myself which way to believe, and that may take until after I've passed (it's not an easy topic to fully absorb, particularly for those of us with limited intellect). That opens me to criticism from both sides of the debate, but I don't particularly care, and my own personal opinion has no power to sway the masses toward doing or not doing something particularly bad or good.
