A paper on US temperature adjustments was published in Geophysical Research Letters on February 5. Download full text here, (pdf, 1.5MB). The University of York has information about the paper including handy links to data.
The paper examines and offers improvements to adjustments to the continental US surface temperature record. The abstract is easy to read and understand:
Numerous inhomogeneities including station moves, instrument changes, and time of observation changes in the US Historical Climatological Network (USHCN) complicate the assessment of long-term temperature trends. Detection and correction of inhomogeneities in raw temperature records have been undertaken by NOAA and other groups using automated pair-wise neighbour comparison approaches, but these have proven controversial due to the large trend impact of homogenization in the United States. The new US Climate Reference Network (USCRN) provides a homogeneous set of surface temperature observations that can serve as an effective empirical test of adjustments to raw USHCN stations. By comparing nearby pairs of USHCN and USCRN stations, we find that adjustments make both trends and monthly anomalies from USHCN stations much more similar to those of neighbouring USCRN stations for the period 2004-2015 when the networks overlap. These results improve our confidence in the reliability of homogenized surface temperature records.
Slate’s response is straight out of the “I told you so” playbook but they haven’t actually read the paper. Continue Reading →

Here’s a place to keep all this together. It’s an important issue
tissue of lies, since the warmists are making a great deal of it and I’m sure a lot of otherwise well-informed people have gained quite the wrong impression from the lies put about by scientists like Gavin Schmidt and Mike Mann that the temperature has been rising for years. Continue Reading →

Source: Inquiry Launched Into Global Temperature Data Integrity
London: 26 April 2015. The London-based think-tank the Global Warming Policy Foundation is today launching a major inquiry into the integrity of the official global surface temperature records.
An international team of eminent climatologists, physicists and statisticians has been assembled under the chairmanship of Professor Terence Kealey, the former vice-chancellor of the University of Buckingham.
Further details of the inquiry, its remit and the team involved can be seen on its website at www.tempdatareview.org. Continue Reading →
Just three days ago Christopher Booker posted The fiddling with temperature data is the biggest science scandal ever which has collected 21,586 comments (h/t Vincent Gray).
The Article is worth reading but most of the comments are not. They are mostly irrelevant and appear to have been mass-produced by opponents of science in order to sabotage the topic (although, like Vincent, I’m not sure about this, as I’m not about to read them all). Continue Reading →
Devastating criticism from William Kininmonth
This is dynamite. Heartland’s November Environment & Climate News reports scientist Jennifer Marohasy and environment editor Graham Lloyd, among others, have learned the Australian Bureau of Meteorology (BOM) has been “fudging” historical temperature records to fit a warming narrative.

The global temperature datasets are slow.
We usually have updates within 30 days of the end of a month, but most are about three months behind, with UAH four months slower than normal.

Anyone know why?

This came up a few days before Christmas. I didn’t get to it then but it needs airing. The surface temperature series of GISS and HadCrut are scarcely worth the disk drives they’re stored on. No wonder the records show warming.
It’s a joke. The shocking truth is that the oldest readings have been cranked way down and later readings artificially lifted to give a false impression of warming. That seems familiar — now where have I read that before…
NOAA changes old temperature records every month. This is a new climate sport in which we imagined Kiwis led the world. But the Yanks have more stamina. They don’t just do it once, they keep on doing it. The data-altering champions in NOAA and NASA put the climate scientists in NIWA to shame. Continue Reading →
We’re working through several answers from the Hon Wayne Mapp, Minister of Research, Science and Technology, concerning questions posed by ACT about the National Institute of Water and Atmospheric Research (NIWA).
The last of the questions posed by John Boscawen on behalf of ACT on February 19 asked about the official graph of the seven-station temperature series which shows warming over New Zealand during the 20th Century.
The answer, on March 1, said the iconic graph was finally justified by work done over about six weeks, from mid-December to early February. I’m sorry, that’s wrong: the graph was not justified by this work; the graph remains unjustified except for the portion related to Hokitika — that’s right, yes, I’ve got it now.
The work NIWA did justified only the temperature history at Hokitika, although it hasn’t been peer-reviewed yet by independent scientists, only by colleagues at NIWA, so there might still be errors in it.
You wouldn’t get away with it at high school
So the temperature graph made from seven weather stations, which NIWA has used for years to prove that the New Zealand climate has warmed, and thus we must take expensive action against global warming caused by humanity’s emissions of carbon dioxide, has never had proper scientific standing.

UPDATE: Comments added and extended 3:30 p.m. February 11.
The Hon Rodney Hide gave welcome publicity in his Leader’s address in the Parliament yesterday to our attempt to obtain the adjustments made to the national temperature record.
Gareth Renowden, at his Hot Topic blog, has again misunderstood what we’re trying to do and tries his darndest to demolish Rodney’s reputation, solely on the basis that Rodney disagrees that the world is dangerously warming from the actions of humanity. Has he not heard of free speech?
However, far from misleading the Parliament, as Mr Renowden scurrilously alleges, Rodney in fact brings its members up to date with the latest developments in the long-running climate scandal, which most of our mainstream media have shown themselves reluctant to do.
Greatest scandal in history of science
Let’s examine his salient points, ignoring the ad hominem attacks on Rodney, the Coalition and me. Here is Mr Renowden, quoting Rodney (RH) (some of my comments in red):
Hide climbs straight into the so-called “climategate” affair:
RH: Climate-gate is now the greatest scandal in the history of science.
Astonishing hyperbole, but straight out of the denial campaign’s play book. Try Googling “greatest scandal in the history of science” and see where the hits are coming from…
I did. They are overwhelmingly about the climategate affair. No problem. In any case, it’s an expression of opinion, cannot be incorrect and is distinctly unastonishing. Continue Reading →
