I've looked at Christopher Brooker's article, it's nonsense. Temperatures are rising, see the IPCC report. If you don't believe the IPCC report, visit*:

RealClimate, a site run by climate scientists, debunks the unpublished report Brooker refers to [1]. It's no surprise that this report wasn't published. The EPA probably does peer-review, so I doubt that paper would have had any legs.

On climate models over-predicting warming, this is nonsense. Climate models can't be expected to exactly track global mean temperature because of internal climate variability. This is why you have a fuzziness to individual model runs.
Additionally, the fact that climate models aren't perfect does not undo the basic laws of physics. Carbon dioxide is a greenhouse gas and traps heat radiation. No matter what nonsense is spurted from the likes of Christopher Brooker or anyone else, this fact can't be undone.

* Of course, if you don't trust the IPCC, you might not want to trust NCAR, the Hadley Centre, NASA GISS, etc. because some of the IPCC authors work at those institutions.
