In this case they are showing raw data that speaks for itself. I don't care who published it, that looks pretty definitively like an attempt at deliberate manipulation of the data on NOAA's part.
I crunched the raw data myself and got the same warming trend that NASA and NOAA get. See http://forums.sandiegouniontri... for details
But the 12 NOAA climate-data "adjustments" in a row that have each cooled the past and warmed the present can't be considered "politicized science" since that could totally be legitimate compensations for random errors. You're totally likely to randomly select the same of six options 12 times in a row; this happens 100/6^12 = 0.000000046% if the time!
The adjustments were made to correct for the effects of station moves from town centers to outlying airport (and other) locations. Drill down into the unadjusted NOAA data (ftp://ftp.ncdc.noaa.gov/pub/data/ghcn/v3/) and you will find that *hundreds* of airport stations have data records going back prior to the existence of airports. Those stations were obviously moved. For more info, see a summary of my own independent analysis of the NOAA temperature data here: http://forums.sandiegouniontri...
