NZ climate scandal: NIWA “adjusts” records to show warming
New Zealand may have its own “Climategate”, including manipulation of temperature readings, according to a combined research project undertaken by members of the Climate Conversation Group and the New Zealand Climate Science Coalition. The researchers claim that temperature readings from seven weather stations throughout New Zealand have been adjusted to show a higher degree of warming than is justified by a study of the original raw data.
Spokesman for the group, Richard Treadgold, said that recent claims that New Zealand is warming have been proved wrong. “Official information clearly shows that temperatures in New Zealand have actually been remarkably stable since 1850. We got the data from the online National Climate Database maintained by NIWA and we made our own graph, which we compared with theirs. The results are shocking.
“NIWA’s official graph (done originally by Dr Jim Salinger, who features also in the emails leaked from the Climatic Research Unit of the University of East Anglia) shows considerable warming, which they give as 0.92°C per century, saying this is consistent with global warming over the 20th century. But the actual temperature readings taken from the thermometers show an almost flat trend for 150 years.
“These figures all come from NIWA. So, why are they so different from each other? Because NIWA has adjusted the earliest temperature readings downwards by up to 1.3°C, which has the effect of introducing a false ‘warming’ as the graph then ‘climbs’ to the present day. It’s a disgrace. So far, neither Dr Salinger nor NIWA has revealed why they did this,” said Mr Treadgold ..
