"warming in New Zealand over the past 156 years was indeed man-made, but it had nothing to do with emissions of CO2-it was created by man-made adj..."

Read the whole story at NZ Climate Science where they "compared raw data for each station (from NIWA’s web site) with the adjusted official data". Shockingly they found that whilst the official temperature record shows a clear rise in average temperatures, the raw data shows nothing of the sort. On digging further they discovered that:
"About half the adjustments actually created a warming trend where none existed; the other half greatly exaggerated existing warming. All the adjustments increased or even created a warming trend, with only one (Dunedin) going the other way and slightly reducing the original trend.

The shocking truth is that the oldest readings have been cranked way down and later readings artificially lifted to give a false impression of warming, as documented below. There is nothing in the station histories to warrant these adjustments and to date Dr Salinger and NIWA have not revealed why they did this.

One station, Hokitika, had its early temperatures reduced by a huge 1.3°C, creating strong warming from a mild cooling, yet there’s no apparent reason for it.

We have discovered that the warming in New Zealand over the past 156 years was indeed
man-made, but it had nothing to do with emissions of CO2—it was created by man-made
adjustments of the temperature. It’s a disgrace."

I wonder what the explanation will be and what other "official temperature records" have been likewise adjusted?
