The IPCC tend to be on the very conservative side as they only endorse the most certain, and play down the most extreme as they tend to use normal distributions, which in a situation of rising temperatures they aren't. That they are government appointed probably has some influence too. Some have called it dangerously misleading in the underestimates - sea level rise has been tracking the worst case of the IPCC range of projections. Where that leaves us, I'm not sure.
