It
absolutely has. As the post I linked observed, the UAH record is
actually different in the 1979-1983 period than the HadCRUT4 data, but Spencer is plotting them starting at both at 0.0 -- that is, by plotting them on the same axis he's making you believe that they agreed in the year 1983, which they absolutely did not. This had the effect of globally lowering that curve with respect to the HadCRUT4, when in fact it was a temporary blip and for the rest of the period plotted, they are in very close agreement.
The charge that the models chosen differ over the last decade plus has not been laid.
He also manipulated the presentation of the climate model data by choosing the 1979-1983 baseline, a period where the agreement was not the closest between the models and the data. By doing this, he's making it look like the models were off for the next 20 years, when in fact it was mainly only the 1979-1983 period that they were wrong during. In other words, he's taking the worst possible five year stretch for the climate models and then just straight up lying to you, because he's making it look like they
did agree at 1983 and then disagreed later.
...I don't even know why I bothered with this, you either won't understand what I just said, or you'll ignore it.
It you wish to compare with the IPCC, then take into account that the IPCC made the Medieval warm period disappear following their initial report.

No, they didn't "make the medieval warm period disappear."
By the way: Here's the actual figure from the first IPCC report:

Somehow, whoever made the image you linked managed to have actual IPCC temperatures for the medieval period, when the iPCC figure is merely a schematic not presenting real data. Now that is fascinating; could it be that your favorite climate "skeptics" are
falsifying data? Nah, couldn't be...
