We will see the final version of the IPCC's Fifth climate assessment soon. But here is something interesting from the last draft circulated. First, here is there chart comparing actual temperatures to model forecasts. As you can see, all the actuals fall outside the published ranges from all previous reports (with a couple of the most recent data points added by Steve McIntyre in red).
A problem, though not necessarily a fatal problem if the divergence can be explained. And the IPCC is throwing out a lot of last minute explanations, though none of them are backed with any actual science. I discussed one of these explanations here. Anyway, you see their data above. This is what they actually write in the text:
the globally-averaged surface temperatures are well within the uncertainty range of all previous IPCC projections, and generally are in the middle of the scenario ranges”.
This is completely absurd, of course, given their own data, but it has lasted through several drafts, so we will see if it makes it into the final draft. My guess is that they will leave this issue out entirely in the summary for policy makers (the only part the media reads). Steve McIntyre discusses the whole history of this divergence issue, along with a series of studies highlighting this divergence that have been consistently kept out of publication by climate gatekeepers.
The frustrating part is that the IPCC is running around saying they can't have a complete answer on this critical issue because it is so new. By "new" they mean a frequent skeptics' observation and criticism of climate models for over a decade that they have only recently been forced under duress to finally consider.
