7SS – R.I.P.

dead parrot

Monthy Python’s dead parrot sketch is famous around the world and still funny. It provides an enduring, oddly acceptable image of death. Just like the death which suddenly overtook the old “official” NZ temperature record which NIWA were defending all year up until, oh, quite recently. But their defence of it died too. Shrivelled up, suddenly dessicated.

Stone dead

NIWA’s long-defended ‘Seven-station Series’ (7SS) is as dead as the parrot in Monty Python’s famous sketch… it rests in peace, bereft of life, demised; it has shuffled off its mortal coil, its metabolic processes now history.

On the eve of Christmas, when nobody was looking, NIWA declared that New Zealand had a new official temperature record (the NZT7) and whipped the 7SS off its website.

NIWA’s spin-doctor, Network PR, likes to pretend that the NZT7 is really only a ‘revised’ version of Jim Salinger’s original 7SS. So when does a revision become a replacement? Continue Reading →

Nothing random about NIWA

No dice — or are they loaded?

Loaded dice for temperature record?

— by Barry Brill, Chairman of the New Zealand Climate Science Coalition

In producing a new temperature record for New Zealand (NZT7), NIWA has again adjusted the raw measurements. Whilst no systemic error was found, one-off issues were raised by random site changes, especially during the early decades of the 20th century.

Curiously, NIWA’s adjustments are not random. Instead, their changes display a near-perfect symmetry, where amplitude is directly proportionate to age. Small adjustments apply to the 1950s, grow larger back in the 1940s, and larger still in the 1930s – before reaching their apogee in 1910-20.

Could this have happened by chance?
