Bending over Backward to be Scientifically Conservative

Justin Gillis:
"Climate change skeptics often disparage these periodic reports from the United Nations, claiming that the panel writing them routinely stretches the boundaries of scientific evidence to make the problem look as dire as possible. So it is interesting to see that in these two important cases, the panel seems to be bending over backward to be scientifically conservative."
