This article is really just charts of surface temperature reconstructions. The first charts are the real global and hemispherical and continental reconstructions. And down below you'll see Anthony Watts' very odd notions. (He can't decide which "not global" reconstruction he likes best, so this week he's offered two different versions. Neither of which is global, and for one of which he couldn't even get the dates right.)

IPCC hemispheric and global surface temperature reconstructions
This first one shows the northern hemisphere, southern hemisphere and global surface temperatures as seen by the IPCC in the AR5 report - looking back 2,000 years.
|Figure 5.7 IPCC AR5 WG1 Reconstructed (a) Northern Hemisphere and (b) Southern Hemisphere, and (c) global annual temperatures during the last 2000 years. Individual reconstructions (see Appendix 5.A.1 for further information about each one) are shown as indicated in the legends, grouped by colour according to their spatial representation (red: land-only all latitudes; orange: land-only extra-tropical latitudes; light blue: land and sea extra-tropical latitudes; dark blue: land and sea all latitudes) and instrumental temperatures shown in black (HadCRUT4 land and sea, and CRUTEM4 land-only; Morice et al., 2012). All series represent anomalies (°C) from the 1881–1980 mean (horizontal dashed line) and have been smoothed with a filter that reduces variations on timescales less than ~50 years.|

Anthony Watts' strange ideas of what global surface temperature looks like
You can regard this section as the short version of two recent articles, which were both rather long. For an explanation read the articles doozy and doozy doubled.
Compare Anthony Watts contradictory and competing notions of global surface temperature - in the space of only a couple of days. The top panel is Anthony's global surface temperature as he portrayed it from his view of the "global" Pyrenees in Spain. The bottom panel is Anthony's "global" surface temperature as he portrayed it from his view of an ice sheet in cold Greenland. I've animated the bottom panel so you can also compare Anthony's version of global Greenland with Richard Alley's version of GISP2 in Greenland. (Anthony wrongly claims the series starts in 2000. In fact it starts in 1855.)
I've lined up the top and bottom panels so the years are roughly aligned. Anthony claims both top and bottom are representative of global surface temperatures, despite the fact they are each local to tiny different regions, and are not global, and they are quite different to each other.
They cannot both represent global temperatures. The Pyrenees were coldest when Greenland ice sheet was warmest, warmest when Greenland was coldest, and cooled when Greenland warmed.
You can understand why deniers get so confused. They are being told to believe wrong and contradictory stuff day in and day out. Anthony Watts doesn't just get everything wrong, he can't even keep his own wrong consistent.
