2011: a hot cold year

by Gareth January 22, 2012

The NASA numbers are in, and 2011 was the ninth warmest year since 1880 — 0.51ºC above the 1951-80 global mean. Nine of the ten warmest years in the long term record have occurred in this century. According to the analysis released by James Hansen and his team at GISS, a combination of low solar [...]

McLean’s folly 2: the reckoning

by Gareth January 12, 2012

Ten months ago, Aussie “sceptic” John McLean predicted that 2011 would be “the coolest year since 1956″. I pointed out at the time that this was nonsense, and so it has proven to be. I’ve taken the GISS global temperature figure for Jan – Nov 2011 (+0.51ºC compared to the 1951-80 average) and added it [...]

You’re (not) the BEST thing

by Gareth October 24, 2011

Set aside for one moment the fact that New Zealand has just (in every sense of that word) won the Rugby World Cup for the first time in a quarter of a century, and consider instead events in the world of temperature records. (Don’t worry, it won’t take long). A team led by Berkeley physicist [...]

Fools gold: cranks can’t count

by Gareth February 9, 2011

I don’t know whether to laugh or cry. 14 months on from the start of the Treadgold/Climate “Science” Coalition/ACT campaign to cast doubt on the long term New Zealand temperature record, after parliamentary questions, much mud slinging at Jim Salinger and NIWA, legal action, and the expensive and time-wasting reconstruction of a temperature series that’s [...]

The Climate Show #5: on a hot wet green roof

by Gareth January 21, 2011

The Climate Show returns with the first show of the new year, and it’s a cracker. Our guest is Dr Brad Bass, an expert in “green” roofing who joined Glenn in the Auckland studio to discuss the many advantages of growing things (even trees!) on our buildings. John Cook from Skeptical Science gives us an [...]

Everyone agrees: 2010 ties for top temperature

by Gareth January 15, 2011

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 [...]

Warm year passing

by Gareth January 6, 2011

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 [...]

NZ cooling since 1909!

by Gareth January 1, 2011

New Zealand temperatures have been cooling since 1909, a penetrating analysis of NIWA’s new national temperatures series by Friends of Gin and Tonic, the self-proclaimed “#1 AGW Denial Site in Canada & Australia” has revealed. FoGT explain that in the absence of a full statistical analysis of the new series by Treadgold and the NZ [...]

A Christmas cracker for the cranks

by Gareth December 22, 2010

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 [...]

NIWA’s new NZ temperature series: plus ça change…

by Gareth December 16, 2010

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 [...]
