The temperature plots show trends for increasing annual temperatures in recent decades, especially within the Upper Midwest and Alaska, which are indicative of polar amplification.
And this one does graph trend lines for polar stratospheric temperature that on average over recent years would correlate to the trend line for area for PSCs in the article being discussed:
As a final comment on polar amplification, I don't think you could argue the south pole temperature trends offer much support for model performance.
it is very likely that the current trend will continue with polar temperatures rising much faster than the rest of the world [two and a half times faster at the moment.]

Here are some possible choices — in order of increasing sophistication: * All (or most) scientists agree (the principal Gore argument) * The 20th century is the warmest in 1000 years (the «hockeystick» argument) * Glaciers are melting, sea ice is shrinking, polar bears are in danger, etc * Correlation — both CO2 and temperature are increasing * Sea levels are rising * Models using both natural and human forcing accurately reproduce the detailed behavior of 20th century global temperature * Modeled and observed PATTERNS of temperature trends («fingerprints») of the past 30 years agree
There is no imperfection in this reality, it is happening whether we miscalculate or misestimate, the correct focus would be on the polar regions which truly reflect world temperature trends.
I mentioned polar amplification explaining temperature warming trends being greater at higher latitudes.

That is the temperature trend that is reflected by a fair accounting of UHI and that is not amplified by polar extrapolations.
One of the authors of the Monaghan et al. group had previously examined trends in temperature «inferred from skin temperatures from Advanced Very Hi - Res» Radiometer (AVHRR) instruments on polar orbiting satellites» and found «a statistically insignificant cooling trend over continental Antarctica from 1982 to 1998.»
As a result, only 1 out of 7 Global or Land / Ocean (ie, global less polar regions) temperature indices shows a negative trend over that period (HadCRUT4 -0.002 + / - 0.059 C / decade).
We note, however, that the polar regions, where recent warming has been greatest, are overrepresented in the 9 % of the Earth's surface for which observed temperature trends are not available.
