Heat: 2014 breaks global temperature records, 2015 could be hotter - Hot Topic

Gareth Renowden Jan 18, 2015

Last year was the warmest year on record for the planet, analyses by NASA and NOAA show, and it’s possible that 2015 could be warmer still. 2014 was warmer than previous record holders 2005 and 2010, and comfortably ahead of 1998. 13 of the hottest 15 years on record have all occurred since 2000.

Solid Treadgold, easy action (NZ still warming fast) - Hot Topic

Gareth Renowden Dec 03, 2014

It’s time to return to the delusions harboured by New Zealand’s little coterie of climate cranks about the NZ temperature record. Readers may recall that — somehow — the men who lost a court case against NIWA and then folded the charitable trust they’d used to bring the case in order to avoid paying costs, […] … Read More

National Business Review: last bastion of climate denial in NZ pushes de Freitas tosh - Hot Topic

Gareth Renowden Nov 18, 2014

The National Business Review — New Zealand’s biggest-selling business weekly — provides a happy media home for climate deniers of all stripes. Columnists like former ACT Party leader Rodney Hide and right wing spin doctor Matthew Hooton1 are given free rein to rant and rave about climate issues, but occasionally editor Nevil Gibson offers its […] … Read More

Danger Dedekind! Heartbreak Ahead (still wrong, still digging, NZ still warming fast) - Hot Topic

Gareth Renowden Nov 05, 2014

Over last weekend, my post criticising the new paper by Chris de Freitas, Manfred “Bob” Dedekind and Barry Brill that claims warming in New Zealand’s temperature records is only one third of that calculated by the National Institute of Water and Atmospheric Research (NIWA) attracted a flurry of attempted ripostes at Richard Treadgold’s Climate Conversation […] … Read More

NZ cranks finally publish an NZ temperature series – but their paper’s stuffed with errors - Hot Topic

Gareth Renowden Oct 31, 2014

You can’t teach old dogs new tricks, it seems — certainly not if they’re gnawing a much loved old bone at the time. The lads from the NZ Climate Science Coalition — yes, the same boys who tried to sue NIWA over the New Zealand temperature record and lost, and who then folded a trust […] … Read More

Tangaroa gets an overhaul - Griffin's Gadgets

Peter Griffin Jul 11, 2014

NIWA’s research ship Tangaroa has spent the last few weeks in dry dock at the Devonport Naval Base where it is receiving an overhaul that will set it up well for many more voyages of discovery. But the inclement weather in Auckland has hampered efforts to get a fresh coat of paint onto Tangaroa’s bottom. Said NIWA’s operations manager John … Read More

Record winter warmth in NZ: June 2014 breaks 140 year record - Hot Topic

Gareth Renowden Jul 01, 2014

Hot off the press — or to be precise, Jim Salinger’s laptop: June 2014 was the warmest June in New Zealand since 1870, 2ºC above the 1971-2000 average, as measured by the long term “seven stations series” originally devised by Salinger and maintained by NIWA. On the larger 24 station series the month tied with […] … Read More
