Thermometers Say That The US Has Been Cooling For 80 Years

The USHCN graph below shows actual temperatures measured by thermometers in the US. The 1920s, 1930s and 1940s were the hottest decades, before Hansen and Tom Karl altered the data.

    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.
      year month count(*)
      1934 7 16384
      1998 7 15292
      1999 8 10031
      1934 8 9561
      1998 8 8847
      1933 7 8306
      1998 6 7480
      1999 7 6636
      1933 6 6338
      1934 6 5233
      1933 8 3874
      1998 9 3752
      1999 6 2678

  2. 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.
