Crisis in New Zealand climatology

MfE NZ climate impact map

The Ministry for the Environment NZ climate impact map (a digression this, to be sure, but it must be said) — pure fiction, created to frighten children, the scoundrels! Why have they stopped using the tried-and-true method of examining historical weather records to predict the limits of future climate? Why do they trust the output of computer models when they are unverified and their predictive skill is zero? If the models give skilful predictions, why does the IPCC give us umpteen possible futures and tell us: “pick one”, saying “we don’t make predictions”? Why do they believe the models when the IPCC declares that our scientific knowledge of the climate is “poor”? In other words, we don’t have a clue how the climate works — so we don’t know if we dominate the climate. Our Environment Ministry should explain themselves then start thinking for themselves and not just believe uncritically what issues from Greenpeace and the IPCC.

The warming that wasn’t

by Barry Brill

The official archivist of New Zealand’s climate records, the National Institute of Water and Atmospheric Research (NIWA), offers top billing to its 147-year-old national mean temperature series (the “NIWA Seven-station Series” or NSS). This series shows that New Zealand experienced a twentieth-century warming trend of 0.92°C.

The official temperature record is wrong. The instrumental raw data correctly show that New Zealand average temperatures have remained remarkably steady at 12.6°C ±0.5°C for a century and a half. NIWA’s doctoring of that data is indefensible.

The NSS is the outcome of a subjective data series produced by a single Government scientist, whose work has never been peer-reviewed or subjected to proper quality checking. It was smuggled into the official archive without any formal process. It is undocumented and sans metadata, and it could not be defended in any court of law. Yet the full line-up of NIWA climate scientists has gone to extraordinary lengths to support this falsified warming and to fiercely attack its critics.

For nearly 15 years, the 20th-century warming trend of 0.92°C derived from the NSS has been at the centre of NIWA official advice to all tiers of New Zealand Government – Central, Regional and Local. It informs the NIWA climate model. It is used in sworn expert testimony in Environment Court hearings. Its dramatic graph graces the front page of NIWA’s printed brochures and its website.
