9 Reasons for Climate Unchange in New Zealand

Dear Reader,

Just yesterday, the New Zealand Climate Science Coalition released an article giving 9 reasons why a paper published by the climate research arm of the National Institute of Water and Atmospheric Research Ltd (NIWA) is defective:

• It runs counter to all the historical records regarding “NZ average temperatures,”, including those compiled in 1867, 1920, and 1964. The archive shows that current temperatures are slightly cooler than those of 150 years ago.

• Its trend outcome is heavily influenced by data from Auckland and Wellington stations which are declared in the peer-reviewed literature to be contaminated and to show false warming; and it fails to adjust for UHI at any of the six non-rural stations.

• It uses adjustments derived from comparisons between “isolated stations” in direct defiance of the scientific authorities.

• It radically departs from the statistical techniques laid down by its chosen precedent, Rhoades & Salinger. Correctly applied, those techniques demonstrate that New Zealand has experienced no material warming trend during the past century.

• It does not disclose the uncertainties (margins of error) associated with any of its adjustments; and statistically insignificant changes are applied.

• Its high warming trend is created by implausible accumulating adjustments, which lack the random spread and self-balancing effects described in the literature.

• Its sole corroboration, the 11SS, is driven by missing data and is demonstrably flawed ; it serves no purpose other than to damage NIWA’s credibility.

• Recommendations from station reports by the Australian Bureau of Meteorology (BoM) were apparently ignored. The pervasive secrecy surrounding all of the BoM review documents casts doubt on the process.

• Most of the warming in NIWA’s graphs occur during the first half of the twentieth century. This pattern is at odds with NIWA’s official advice that warming was driven by global CO2 emissions – which are concentrated in the last 40 years.

So what?

Well, have a look at the last point about CO2 emissions: "This pattern is at odds with NIWA's official advice that warming was driven by global CO2 emissions". If there's no CO2 emissions-driven warming, there's probably no justification for the Emissions Trading Scheme. Although, this was alleged yesterday too.

I'll keep my eyes peeled for any updates. If it's true, I should hope we don't see a significant rise in power prices either; that'd be nice.

Yours sincerely,

Andrew Greaves.
