It’s six years since NIWA published their Report on the Review of NIWA’s ‘Seven-Station’ Temperature Series (pdf, 8.5 MB), the latest version of the national temperature record. It’s six years, too, since NIWA promised the people of New Zealand (in Parliament) they would publish the methodology in that report in a peer-reviewed journal. But they haven’t done so—maybe they aren’t too pleased with it.
Last year, three scientists associated with the NZ Climate Science Coalition published a peer-reviewed paper concluding the New Zealand temperature rise over the last hundred years was only 0.28°C, much lower than the last NIWA effort, which claimed it was 0.91°C. Though I notice just now when checking the NIWA website they’re claiming 0.92°C.
