   I’m starting to wonder if the daily data has been altered at all? I think only the homogenization process has been tweaked to give anomalies an upward trend.
   Here’s another raw comparison for 1933, 1934, 1998, and 1999 . The rightmost values is the number of temperature max’s above 38C for stations with months that reported at least 25 days of both mins and maxes (the stations used for comparison are stations that are in common to 1930,33,34,98,99).

     Doing the query without regard to station commonality (1999 has about double the stations of 1933, 1934) gives something like …
     The processed data seems to be *very* processed.

   It doesn’t matter. Even with the altered data, there has been no warming trend per century for the last 15 years. There has been a 1C trend for the last 30 years (which would equal a nett benefit to the planet if it warmed by that much anyway) and there has been a 1C trend for the last 60 years.

   So it’s all good news as far as the empirical data goes.

   It’s quite astonishing when you consider the Urban Heat Island effect and their ‘necessary’ adjustments.
