By Jim Salinger, University of Auckland A recent headline – Failed doubters trust leaves taxpayers six-figure loss – marked the end of a four-year epic saga of secretly-funded climate denial, harassment of scientists and tying-up of valuable government resources in New Zealand. It’s likely to be a familiar story to my scientist colleagues in Australia, the UK, USA … Read More

If you think it’s been a warm winter in New Zealand, you’re right. NZ is rapidly approaching the end of a record-breaking winter — the warmest for at least 150 years1. Calculations by Auckland climate scientist Jim Salinger show that NZ’s average temperature for June/July/August is running at 9.5ºC, a remarkable 1.2 deg C above […] … Read More

James Hansen’s tour of New Zealand is off to a flying start, with an appearance on TVNZ’s Close Up, coverage in the Herald (they got his age wrong) and an interview with the Dominion Post‘s Kiran Chug, followed by a business lunch (or a lunch with business) and an evening talk to a packed room [...] … Read More

All of the major global temperature series — surface and satellite — report that 2010 is tied for first place as the warmest year in the long term record. NASA’s Goddard Institute for Space Studies and NOAA’s National Climatic Data Center both have 2010 tied with their previous record holder 2005, while the UK’s Climatic [...] … Read More

2010 was the fifth warmest year in the long term New Zealand record, and December the third warmest, according to figures released by NIWA and analysis by Jim Salinger. Salinger’s rankings are based on the revised “seven station series”. According to Jim: [December] was 1.6 °C above the 1971-2000 average and the third equal warmest [...] … Read More

The National Institute for Water and Atmospheric Research (NIWA) released details of its recalculated New Zealand temperature series last week and in the last couple of days Richard Treagold and the Climate “Science” Coalition have issued statements in reply. And what a contrast they provide: Bryan Leyland for the NZ C”S”C is all bluster, demanding [...] … Read More

Earlier this afternoon NIWA released its recalculated NZ temperature record [full report], and as expected the changes from the “old” seven station series are more or less negligible. The trend over the last 100 years is identical, 0.91ºC per century, as the graph above shows. There are minor differences in some years, and larger ones [...] … Read More

In a bizarre twist to the tale of New Zealand’s climate sceptics and their strange obsession with the minutiae of the history of temperature measurement in New Zealand, it now emerges that they have lodged papers with the High Court [Stuff & NZ Herald, via NZPA], seeking to have the court rule that the National [...] … Read More

The new chairman of the NZ Climate “Science” Coalition, Barry Brill OBE, is certainly not shy about parading his point of view to the world at large. Brill, a lawyer and former junior minister in the 1975-81 “Think Big” Muldoon government, has attempted to argue with John Key’s science advisor, Sir Peter Gluckman, and last [...] … Read More
