Lots of charts and tables and stuff, but try and dig lower than that...and nada. Shouldnt this data be out there and readily available?
For instance here
some NASA data set, which was about as good as i could find. But even they say:
sources: GHCN 1880-01/2011 + SST: 1880-11/1981 HadISST1
12/1981-01/2011 Reynolds v2
using elimination of outliers and homogeneity adjustment
Notes: 1950 DJF = Dec 1949 – Feb 1950 ; ***** = missing
So even that data has been adjusted, mixed with other data, and put into a model and fiddles with.
Maybe someone with good google skills can find out the earths (recent 50 year)temperature.
Do you want to understand how it's calculated, or just a list of estimated annual average temperatures? Both are out there, in vast quantities.
Of course data has to be processed before it's used. For example, let's say a weather station is moved from one end of an airport to another, or instrumentation is changed. This may change the raw temperature readings that result. To produce information usable for trend analysis, the data has to be adjusted by some offset. Or, let's say an instrument goes on the fritz. That data has to be discarded.
Model is not a dirty word. We all use models, all the time. That said, producing a gridded average of temperature hardly qualifies as modeling.
There are numerous reconstructions of the surface temperature record, professional and amateur, all over the internet. Open Mind and Blackboard have some of the amateur efforts. Warming is rapid and unequivocal.

Who knows? Will anyone put it in the literature? No, never. Even scientists have stupid opinions, especially about things outside of their areas of expertise. Freeman Dyson on climate change or Linus Pauling on politics spring to mind. The test is what they publish and what, of those things they publish, endures.
