It seems that Richard Treadgold, he of the “climate conversation” that isn’t, wants me to engage in an exchange of views. Following a brief flurry of comments at the Coal Action Network blog, Treadgold writes:
Here’s my challenge: let us, you and me, persevere with this most crucial of national debates.
I am afraid my answer is no, Richard, and I shall explain why.

New Zealand’s merry little band of climate deniers are turning out to be a right bunch of Cnuts. Sea level rise and its implications for Christchurch and the wider world have been making news in recent weeks — as have new projections of rapid sea level rise over the remainder of this century. So what does a good climate denier do? To stay faithful to their core belief — that climate change isn’t happening, or isn’t going to be bad — they have to argue against policies designed to deal with its impacts, as well as those intended to cut carbon emissions. Sea level rise? Like Cnut, they line themselves up against the waves.
I’ve blogged many times on the challenge sea level rise poses for post-quake Christchurch. The 2011 quakes caused large parts of the city to drop by up to half a metre — effectively delivering decades of sea level rise in a matter of minutes. For some areas of the city tidal and run-off flooding are now commonplace.
The current debate on sea level issues has been prompted by the city council’s long term planning process — which recommends that development should be restricted in areas where future sea level rise is expected to cause problems. Not surprisingly, this has some owners of coastal properties concerned that they will lose out. The council has also looked at the idea of building a tidal barrier across the Avon-Heathcote estuary to protect the city.
Local politics and property owner self-interest is bumping into the harsh realities of climate change, leading to a wide variety of responses — including “it isn’t happening”.

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, managed to get their “reconstruction” of the NZ temperature record through peer review and into the scientific literature. To no-one’s surprise, they found that warming in NZ was only one third of that found by NIWA and a generation of NZ climatologists. To do that, they had to torture the data beyond endurance, as I showed at the time.
Equally unsurprising is that Richard Treadgold, prime mover of the whole fiasco, felt moved to respond in a number of typically prolix posts at his blog. His first, What Mullan actually says, purports to lay out the disputed points:
…I think these are the debating points he’s trying to make, lined up with the passages in which he makes them.
One small problem. This is not a debate. The facts are what the facts are, just as the temperature data is what it is. No amount of handwaving — or appeals to judicial authority — can change the facts of this matter. What can change is the interpretation placed on those facts, and that’s where Treadgold et al went wrong on day one.
In 2010 they decided — and explicitly told the world — that NZ’s climate scientists had been cooking the books. Everything they’ve done since has been a part of building a false narrative, a silly superstructure of misinterpretation and misdirection clumsily bolted together, designed to fool anyone sympathetic to their position. The new paper, by de Freitas, Dedekind & Brill 2014 (dFDB 2014) is just the latest effort to prop up that tottering edifice.
I have no intention of wasting time by playing along with Treadgold et al’s narrative. There are so many misdirections and misunderstandings on display in his sequence of posts that it would take a magnum opus to deal with them all. If I thought that by doing that I might change their minds — win them over to the world of climate rationality — then I would be happy to do it, but Treadgold et al are not what I would describe as rational actors. They admit no facts that are inconvenient to their world view, and show no sign of educability on climate science.

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 blog. One — by Bob Dedekind — sets out to be a rebuttal of my original post. Sadly for Bob and his co-authors, he has only managed to dig himself into an even deeper hole.
For the sake of the record, therefore, I have taken the time and trouble to deal with each of his points in detail. The results of my researches do not make pretty reading for De Freitas, Dedekind, Brill, or the editorial team, reviewers and publishers of Environmental Modelling and Assessment.

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 to avoid paying court-ordered costs — have finally found a learned journal gullible enough to accept and publish their shonky reworking of NZ’s temperature record. Earlier this month Environmental Modelling and Assessment published A Reanalysis of Long-Term Surface Air Temperature Trends in New Zealand by ￼CR de Freitas & MO Dedekind & BE Brill (DOI 10.1007/s10666-014-9429-z).
My attention was drawn to dFDB 2014 by an NZCSC press release, and yesterday Richard Treadgold, the man who kicked off the whole sad affair five years ago, posted a disingenuous and misleading article about the paper at his blog. As you might expect given the authors, the paper does not call for an upward revision in the amount of warming NZ has experienced over the last century. The abstract concludes with the following:
Current New Zealand century-long climatology based on 1981 methods produces a trend of 0.91 °C per century. Our analysis, which uses updated measurement techniques and corrects for shelter-contaminated data, produces a trend of 0.28 °C per century.
As you might also expect, given the authors and their respective track records, the paper is riddled with schoolboy howlers and outright misrepresentations. It would probably never have seen the light of day without the assistance of Chris “Pal Review” de Freitas and his undoubted ability to steer tosh to publication.
