Global warming?

There is a new paper just published that drops the trend of the New Zealand temperature record (NZTR) to 0.28C per century, down from ~0.9C per century. The paper has finally made it through peer review more than a year after it was submitted to the journal Environmental Modeling & Assessment.

A Reanalysis of Long-Term Surface Air Temperature Trends in New Zealand
C.R. de Freitas with M.O. Dedekind and B.E. Brill.

Abstract

Detecting trends in climate is important in assessments of global change based on regional long-term data. Equally important is the reliability of the results that are widely used as a major input for a large number of societal design and planning purposes. New Zealand provides a rare long temperature time series in the Southern Hemisphere, and it is one of the longest continuous climate series available in the Southern Hemisphere Pacific. It is therefore important that this temperature dataset meets the highest quality control standards. New Zealand’s national record for the period 1909 to 2009 is analysed and the data homogenized. 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.

Conclusion:

Using well-accepted homogenization methods, we have derived a mean land surface air temperature trend for New
Zealand over the past century of 0.28±0.29 °C per century, which is considerably less than the S81/M10 value of 0.91±
0.30 °C per century. By excluding weighted averages and including adjustments which are not statistically significant,
S81 may have allowed too many “false positives” to occur. In addition, using long comparison time periods may have
allowed creeping inhomogeneities and undocumented shifts at reference sites to skew the individual adjustments. This is
borne out by Table 5, which demonstrates that in every case the S81 station adjustments greatly increased the individual trends, while the RS93 method resulted in equal numbers of increases and decreases. As noted previously, S81 did not account for gradual effects such as sheltering or UHI. The detrending of Albert Park in Auckland and Kelburn in Wellington also contributed significantly to the mean trend result.
We have also shown that a very similar outcome would follow if those two stations were not corrected but simply omitted
from the series.

Thought this might generate some discussion.

The quibbling over methodology is a common diversion by 'pseudo skeptics'.

You can present the evidence again and again and they default to the same diversionary tactics.

Another tactic is to accuse thousands of scientists of lying, cheating, falsifying or massaging data just so they can get on the research grant gravy train.........

No, only about 12 (max) who do that. Only 2 confirmed, but the other 10 are associates who have based their papers on work by those 2. Where do you get this number of "thousands" from?

Most of the scientists who are currently researching climate are using the same data, and coming up with different results. That alone is what tells us that the science is not settled.

Strange shit happens with weather patterns, always have done and always will do, nothing new there. I remember (as a kid in PN) it snowing in Ashhurst and later in life (early 80's) living in Taupo where the temperature was frequently in the early to mid 30's during one summer.

in other words it's bullshit science,
they will never get the science settled because there is no control eg another planet earth

I believe Global warming is due to Terrorists with box cutters.

[unstuck]

I blame NASA, all those rockets and shit poking holes in the ozone layer.

[mashman]

I believe that global warming is us moving closer and further away from the sun... and A.G.W. and hot bitches constantly gettin their tats oot.

[BoristheBiter]

I believe you guys need to worry less and ride more.

What are the odds on a KB 3:1 ratio on that?

[yokel]

I believe Global warming is due to Terrorists with box cutters.

Almost, the same outfit that dreamed up terrorists with box cutters also dreamed up global warming/climate change.
Hence all the disinformation and confusion
