Still Waiting!

February 27, 2013

By Paul Homewood


I am still awaiting answers for the following questions I have raised.


GHCN Temperature Adjustments

Last October, I raised the issue with NCDC of a tranche of temperature adjustments made by GHCN in Iceland, (cooling the past, naturally.) I specifically requested details of how they arrived at the adjustment for one station, Stykkisholmur. The full story is here.


Immediately, Bryant Korzeniewski responded:-




Despite several chase ups, which have been responded to, I still await a reply to my question.


Adjustments to US Temperatures

On 20th Feb, I emailed Deke Arndt of NCDC, to ask if he could explain how the 1934 temperatures for Iowa had been adjusted down by over a degree from those originally recorded.


As of yet, no answer. On previous occasions, Deke has always responded promptly to my inquiries.

Kansas “Record” Temperatures

On 21st Feb, I contacted Dr Chuck Rice, of Kansas State University, to ask for comments about a statement he had given to the Irish Times, which seemed to imply that temperature records had been broken by a wide margin in Kansas last year.


No answer yet.


Story here.




I don’t expect people to jump up straightaway to my requests, and I am sure they have a lot of better things to do. But they are all on the public payroll, and, in the case of NCDC, have a duty to be transparent.

Furthermore, they should not be difficult questions to answer. Which rather leads to the conclusion, might their answers be the slightest bit embarrassing?





Again no answer as yet.

    Hello, Paul, I guess that you will just have to be patient for a few more weeks, or pose the questions again. When I read of the Kansas data I sought out Chuck Rice’s email address, and indeed composed an email, but decided in the end not to send it. If you like I’ll collect it and send it or a modified version. He really ought to be brought up to speed on using real data. These guys should be left in no doubt about their mistakes, deliberate or just through ignorance, I feel.

    Cheers, Robin

    Do you have the data organised so that you can easily see, for a given date (e.g. in 1934) what proportion of past records are adjusted down versus up?

      I’ve only done 1934 itself. Each state is listed. The only ones adjusted up are California and New Mexico.

        I’d forgotten that you’d listed everything, state by state.

        Doing a quick look through your list, that means that for 44 states, 1934 records were adjusted down, for 2 it stayed the same and for two the past temperatures were adjusted up.

        They definitely have some answering to do.
