New New Zealand temperature records - no warming

Via Scoop, sceptics in New Zealand have persuaded the country's weather bureau to revise their temperature records.

NIWA has abandoned the official national temperature record and created a new one following sustained pressure from the NZ Climate Science Coalition and the Climate Conversation Group.

Spokesman for the joint temperature project, Richard Treadgold, Convenor of the CCG, said today: “We congratulate NIWA for producing their review of the NZ temperature record — more than a year after we challenged it — and we think it’s great that NIWA have produced a graph with full details behind it.

“But we note that, after 12 months of futile attempts to persuade the public, misleading answers to questions in the Parliament from ACT and reluctant but gradual capitulation from NIWA, their relentless defence of the old temperature series has simply evaporated. They’ve finally given in, but without our efforts the faulty graph would still be there.”

Congratulations to everyone involved in this effort.  What a triumph for citizen science.

And the punchline is this:

“NIWA makes the huge admission that New Zealand has experienced hardly any warming during the last half-century. For all their talk about warming, for all their rushed invention of the “Eleven-Station Series” to prove warming, this new series shows that no warming has occurred here since about 1960.

I'm honestly surprised that someone on the front line of the AGW debate should take the time to anwer the concerns of an idle civilian who casually lights a firecracker. :)

I totally agree with your concerns about the adjustments that are being made to the temperature record.

But I do have a concern that we might fall into the habits of the alarmists, by beefing up the news with a bunch of spin. You have forced NIWA to take a step forward, which is great. But so far it is only a miniscule step. Perhaps it will lead to greater things.

I hope you keep up the good work,

James Evans,

Oh, but I choose my firecrackers with care, and my answers are for everyone.

Thanks for your kind words and encouragement.

This article is false and directly contradicts the facts, yet cranks still go on about how this is an example of the great conspiracy. Anything and everything gets incorporated into the great conspiracy, in the minds of the common crank.

Honest people can admit when they are wrong. Will this article ever get corrected? I don't think so.

Can you point me to something to support your claim?

Well done Richard et-al
The qu of verifiable data haunts every logical thinking person, especially in these scamulous, rake the cream off the top days.
The BOM is having a shift in data presentation, not so long ago it was quite simple to access un-tinkered data; now their website leans you to corrected, verified and sanitised stuff.
What I particularly dislike are the temp. anomaly graphs so common these days.
The dumbing down of our base education systems over the last 40 years or so is having its effect viz the average person does not have the wit or knowledge to make an effective judgement on just about anything beyond their everyday needs.
Conspiracy, to right.
