Defrauding The Public Through Baseline Shifts

GISS uses an insidious trick to hide their data tampering. They cool pre-1963 years, and warm post-1963 years. This makes their data tampering look much less severe than it actually is. A better visualization is to normalize the graphs to the most recent common data, and show the total magnitude of the tampering. The animation below shows that.

    The 2003 link doesn’t work.

    This is great stuff but I want to see the source.

    Judith Curry (in a 7/2014 blog post) links to a blog post by Brandon Shollenberger that seeks to support how surface temperature data is handled while being critical or dismissive of your criticism of its handling. I thought you might want to read the criticism and respond to it, if you haven’t yet. The post is linked below:

    Best wishes,

    Despite all the explanations I’ve heard from each of these government agencies that felt the need to go back in history and examine the temperature record. It’s just strange that every temperature record prior to 1979 was cooled and every one after has been warmed. I don’t care what the explanation is. Just like the medieval warm period was accepted as being a very hot period on the earth and now it’s contested and swept off as localized phenomenon.

    It doesn’t smell good. Same as the climategate emails. Everyone in the media says nothing to look at here. That makes me give more weight to it.

    In Roma, Western Queensland, where I grew up, I was told of the night in the early 1930’s – 1934??, where a heat wave produced one day/night, a minimum temperature of 100 degrees F. It did not drop below that all night. I remember the heat well. Later in January 1939, age 11, i recall seeing our thermometers read 118 degreesF. (Shade Temperature). I was covered in blisters caused by the extreme dry heat. Pores were sealed by the low humidity and perspiration only produced by a hard pressure on the skin. These readings(37.8C & 47.8C) have since been “homogenised” down by the Met. Bureau.

  6. Never does the media report on the weather,without giving temperature readings,out of context.
    Their reports are always sensational.
    I believe that they are trying to mislead the public.
    The thermometer was invented during the Little Ice Age.
    Thank God the temperature has gone up.🐸
