If the sun isn't responsible, then what? How do you explain warm trends which date back thousands of years? And I'd like to know which sources of yours ruled out the sun as the primary cause of climate change, because Dr. Richard Lindzen of MIT, one of the top men in his field, say that the sun is the cause. Dr. Tim Ball, another top guy, says so too.
your chart is cherry-picked and placed at misleading scales and flat out wrong. for one thing, that simply isn't the cru data. and it certainly isn't the entire record of those sources. a better plot looks more like this:
hmm, amazing how that changes the picture, isn't it?
And your chart is cherry picked as well. Lets go back a half billion years then, where you can see there is no correlation between co2 and an increase in temperature.
