The increase in slope is detectable by visual inspection, but I grant that it is small.
The important thing to remember is it's rising, and fast. From about 315 to 400 from 1960 to the present. About 25% higher in half a century, with very little noise other than the sinusoidal seasonal variation. I can't think of any natural, global parameter that has changed so much so quickly, and in such a smooth and predictable fashion...except for arctic sea ice: it's changed twice as fast.
As for TB's comment, it's his usual attempt to change the subject and confuse the issue. He presents a graph about who is creating the carbon, not how much there is or how fast its growing worldwide over time. The two issues are related, but not the same, because the earth can process carbon and remove it from the atmosphere. The fact that natural sinks can no longer cope with the growth in CO2 concentrations is the problem, not which country is to blame.

Actually, you're both wrong.

- No, that chart is not linear since 70. It is quite curved. Hold the edge of an envelope up to it if you don't believe me.
- Curve in name only.
