Now, you might conclude that "0.2% - 0.3%" means that "man did not cause the warming."

But this isn't, in a more exacting sense, what the author(s) actually concluded.

And, in my mind, if they were to reach the same exact conclusion that you you just did, then they would undoubtedly have to conclude that CO2 isn't a greenhouse gas in the first place...something which I seriously doubt that they would do.
