Dynamite changes to raw readingsRichard Treadgold | August 15, 2010
What has NIWA done to the original raw temperature readings? What do the adjustments look like? I can do little better than to show them on a single graph.
This clearly shows two important things:
1. The original readings show a slight, insignificant warming.
2. The adjustments have the effect of cranking the older readings down so the trend is now one of strong warming. Indeed, it is 50% greater warming than the globe itself.
Just as our original paper showed, back in November 2009, New Zealand has indeed been the subject of man-made warming, but only by adjusting the figures. Still, to this very day, NIWA refuse to detail the adjustments they made and why they made them.
They have had every opportunity to do this, as we have asked again and again. But they have met us with prevarication, obfuscation and diversion. They sent us to scientific documents where we found no mention of the methodology. They described in detail altitude adjustments where weather stations had moved and suggested we knew nothing about the realities of measuring the temperature and the adjustments that are often required; but it turned out that none of the weather stations were adjusted for altitude changes in the way they said.
In other words, they lied to everybody, in the newspapers and in the Parliament.
Finally, NIWA essentially agreed that they could not justify the adjustments, they didn’t even have the adjustments and therefore they would create a new temperature series from scratch and have it peer reviewed and publish all the data.
This they have not done.
But in the meantime they continue to publish, quote and recommend this “temperature record” which they cannot justify. We believe they ought to withdraw it, and our only recourse now is to ask a judge to order that they withdraw it.
The coming weeks will be interesting.
