In a question related to how great he thinks I am, 'Always 100 percent accurate' (and ironic name) claimed that atmospheric CO2 increase [always] follows a global temperature increase. I've heard that argument here several times from GW skeptics, but why do they keep making it?
If you examine the following 2 plots from 1960-Present:

http://en.wikipedia.org/wiki/Image:Instrumental_Temperature_Record.png
You'll see that atmospheric CO2 and global temperature are increasing at the same time, with temperature lagging slightly behind CO2 increase.
The logic is that because CO2 followed temperature increases in the past, it must always follow in that order, but that's a logical fallacy. Of course CO2 can cause a temperature change because it's a greenhouse gas! 1 more plot worth examining:

So why do GW skeptics keep repeating this false claim?
