Of course you do. Macroevent theories are comprised of hundred or thousands of data points. The theory itself is the plasible event the data points to.
You're kidding, right? You test a theory by testing whatever the theory predicts. A theory is meaningless if you can't test it. Testing the source data isn't testing the theory. You must test the results and see if they matched predictions. Global warming doesn't predict levels of CO2 in the past. It predicts temperature changes in the future. You test the latter, not the former to see if it's right.

Erm, in the sliver of space representing 2000-2007 where the little lines remain close (though slightly above) to the 2000 baseline?
That chart is a set of predicted temperature changes. All of them predict a pretty steady temperature increase over the next century. You should be able to measure this once you've gone 10% of the way. Not being able to do so calls them into question.

Of course, going back to
the other chart, we see that temperatures
have increased slightly since 2000. Just as predicted!
Huh? Those are historical data Joph. There's no prediction there. They measured temperatures up to around 2002. There was a slight increase after 2000, but it's pretty clearly tapering off. And it has continued to for the next 7 years. Something that was *not* predicted by Global Warming theories.

You need to learn to read charts.
To be able to tell one that predicts future trends versus one that's just historical data? Yeah. That's me with that problem...

The models show it about .1 degree warmer from 2000 to 2007. The temperature chart shows it about .1 degree warmer in the years following 2000. So, ummm... yeah, you cleverly proved that the models are pretty much dead on. Congratulations!
Huh? The chart you linked doesn't show that at all! Of the three data points after 2000, the highest is only .05 degrees above the 2000 number. Where do you just magically double that value Joph?
And the 2000 number is .18 degrees
lower than the peak in 1999 (actually 1998 I believe).

Your "argument" relies on comparing the average of one decade with an outlier data point against another decade which was slightly warmer year to year but missing the outlier to skew the average.
No. It doesn't. My argument is based on trendlines. I'm not looking at the outliers. The trend over the last 10 years has been significantly shallower than the trend for the preceding 30 years. That's my point. Whatever was causing increased temperature increase during that earlier time period has slowed down in the last decade. Yet emissions of greenhouse gas have not been reduced.
Ergo, the previously measured increase cannot have been caused by greenhouse gases alone. More importantly, greenhouse gas emissions almost certainly were not the major cause of that earlier temperature increase. Some other factor either contributed to the earlier period's rapid temperature increase *or* has intervened to slow down that increase over the last decade. In either case, that effect (whatever it is) seems to be having a much more significant impact on global temperatures than greenhouse gases.
Get it? That's how science works. You're latching onto one theory and defending it to the death. I'm looking at the freaking facts and drawing some very obvious conclusions. Does this mean that CO2 emissions have *nothing* to do with temperature? Of course not. But it's not such a significant factor that we should be spending (wasting) billions of dollars reducing emissions.
