re: That's why you need the paper
from p. 3:
The more frequently a climate scientist’s work touches on sensitive or controversial issues, the more interference he or she reported. More than three-quarters (78 percent) of those survey respondents who self-reported that their
research “always” or “frequently” touches on issues that could be considered sensitive or controversial also reported they had personally experienced at least one incident of inappropriate interference. More than one-quarter (27 percent) of this same group had experienced six or more such incidents in the past five years.
Oh, and, btw, NCAR is an independent agency whose scientists are not Federal employees (also from page 3). Their significantly lower incidents of interference are given as contrast to those whose employment is more easily threatened.
That's why you need the paper, TB -- you who wrote I haven't read anything except the survey number tables. But I posted the link, so people can do their own thinking.
