What you posted is the opposite of the truth. Models have quite consistently tended to over-estimate future temperatures:

The tables below provide a comparison of model predictions with actual observations and provide a yes-no-undetermined score of whether the models are successful or not.

Scoring is won-lost-tie system. A win means models and observations reasonably agree. A loss means significant disagreement. A tie means the models or observations give contradictory results.

Summary score:

Global Warming Models: Predictions vs. Evidence [Jay Richards]

Although it's not yet updated to the new IPPC report (which hasn't actually come out yet), Doug Hoyt has developed a scorecard to compare the major predictions of global warming models with actual observations. He gives each prediction a "yes-no-undetermined score." So if the major models' prediction is confirmed, the score at the beginning would be 1-0-0. So how do the models score when compared with the evidence? The final score is 1-27-4. That's one confirmed prediction, 27 disconfirmed, and 4 undetermined.

Hoyt isn't a newcomer to the debate. He's published important work on sunspot observations over the past 4 centuries. He also coauthored a book called The Role of the Sun in Climate Change , published by some fringe outfit called "Oxford University Press."
