I can try to answer part of that, sir.
The language on uncertainty on levels of competence was determined by the scientists. It's not a matter of taste; it's a matter of statistics, more than anything else, and of scientific judgment.
I was in Paris, because I'm a member of the IPCC bureau. I don't recall any instances when governments were able to change those statements of uncertainty. What the Chinese did try to do was modify some text that had to do with the relative contributions of human factors and solar variability to the radiative forcing that we've seen. They were successful in actually removing a piece of text; nevertheless, the information is there in the graphs very clearly for anybody to read.
