"Some researchers have argued that it is unfair to attack the IPCC too strongly, pointing out that some errors are inevitable in a report as long and technical as the IPCC's round-up of climate science."<p>Yeah, especially if you willfully ignore them when they're known, in favor of a position.<p>I'm getting the sense that advocacy is playing too high a role in both the science and the policy of climate change. Indeed, advocacy seems to have coupled science and policy into one large system.<p>I'm also wondering if "climate change" shouldn't even be a phrase in common usage, at least not the way we use it to refer to an accepted direction in policy and earth science.
