The specific charge brought against the Kiwi government was that it’s climate scientists had taken the raw temperature records of the country and then adjusted them artificially with the result that a steeper warming trend was created than would otherwise exist by examination of the raw data alone.
Indeed, the original Kiwi records shows no warming during the 20th century, but after government sponsored climatologists had manipulated the data a warming trend of 1C appeared.
Not to worry, I'm sure nobody else did this exact same thing. I'm sure we can be highly confident of data and data analysis from a group of people collectively committed to the results they give us as a moral issue as much as a scientific angle.
