The New Zealand Government’s chief climate advisory unit NIWA is under fire for allegedly massaging raw climate data to show a global warming trend that wasn’t there. The scandal breaks as fears grow worldwide that corruption of climate science is not confined to just Britain’s CRU climate research centre.
In New Zealand’s case, the figures published on NIWA’s [the National Institute of Water and Atmospheric research] website suggest a strong warming trend in New Zealand over the past century [go to the link to see the graphs; the fraud is astonishing] But analysis of the raw climate data from the same temperature stations has just turned up a very different result [go to link above to see graphs]
Gone is the relentless rising temperature trend, and instead there appears to have been a much smaller growth in warming, consistent with the warming up of the planet after the end of the Little Ice Age in 1850.The revelations are published today in a news alert from The Climate Science Coalition of NZ:
Straight away you can see there’s no slope—either up or down. The temperatures are remarkably constant way back to the 1850s. Of course, the temperature still varies from year to year, but the trend stays level—statistically insignificant at 0.06°C per century since 1850.Putting these two graphs side by side, you can see huge differences. What is going on?
Why does NIWA’s graph show strong warming, but graphing their own raw data looks completely different? Their graph shows warming, but the actual temperature readings show none whatsoever!
Have the readings in the official NIWA graph been adjusted?It is relatively easy to find out. We compared raw data for each station (from NIWA’s web site) with the adjusted official data, which we obtained from one of Dr Salinger’s colleagues.SNIP
