I don’t think you actually mean “raw data about temperature change” because most of the warming is only seen in the processed readings, not the raw data.
Consider the USCRN raw temperature dsta, which comes from the gold standard observation network, with carefully sited locations and the best instruments. It was designed from the start to have reliable observational data needing few, if any, corrections. It has seen very little warming since it went live about 15 years ago. True, it only covers the US, and 15 years isn’t yet long enough to have enough statistical significance for a confident claim of little to no warming, but it is getting close. One can’t simply ignore the data, though. It will soon require an explanation.
