More recently Mazen has made the similar claim:
'The IPCC claim that most of the recent warming (since the 1950s) is due to man assumed that current models adequately accounted for natural internal variability. The failure of these models to anticipate the fact that there has been no statistically significant warming for the past 14 years or so contradicts this assumption. This has been acknowledged by major modeling groups in England and Germany”'
I suspect the stuff about modelling falure is just handwaving.
Actually he's just lying. In an infamously misrepresented paper, Mojib Latif showed that models could generate a decade
or even two of no significant warming and modellers did not kick up any sort of fuss.
Lindzen may be twisting the sense to "no model run 14 years ago predicted exactly what's actually happened", but of course no model is
expected to predict the year-by-year evolution of the climate and even so long ago they were running ensembles.
It's all bollocks, but Lindzen, the
WSJ, the blogosphere, waddya gonna do?
Perhaps what Lindzen should have written is:" there has been global warming over the last few years but it has not been statistically significant".
What he
should have written depends on his objective, and that isn't to
inform in this case. Lindzen is first and foremost a polemicist, and for his purposes he wrote just what he should have done. In Lindzen we see a marriage of intelligence with complete absence of integrity.
Perhaps I have it wrong, but I am assuming that Madzen’s null hypothesis here is that there has been no increase or decrease of underlying warming over this fourteen year period.
I'm assuming his hypotheses are entirely concerned with the gullibility of his audience, and the best ways to exploit it.
Were he speaking as a scientist, his null hypothesis would be that there was
no underlying trend in global temperature over the period, which warming would have to be tested statistically against.
It's worth noting that 95% as "statistically significant" is quite arbitrary. Deniers naturally seek out the longest period that sneaks under that. When Phil Jones was ambushed the significance was 93% in 15 years (1995-2009). 2010 pushed it to 95% so now it's back to 14 years from '97. In a few years they'll be down to 12 or less, mark my words

.
At some level of significance the visible evidence that there was such warming is not strong enough for him to reject that null hypothesis. But that null hypothesis it seems to me would only be of interest if the world began 14 years ago. However I am ready to be corrected by Westwall or Furcifer or any other defender of Madzen
I'm never going to defend a scientist who keeps his emails secret just because he's working for the private sector. Damn' suspicious, that sort of behaviour
