Re Phillip Bratby’s comment.

I need to do some research but I think you will find that the CET is not continuous that is read from the same stations that have remained in the same places without change. It has been spliced from different “continuous” records over time.

Whilst it is improbable that the Armagh record is also from exactly the same station, I think it has remained in the same place.

No doubt other readers can comment.

Ladies and Gentlemen, the Netherlands is globally warmed by the Hansomatic AlGoreithm thusly:

pre-16/05/1950 – thermograph in large pagoda cabin 2.2m over a mown field
17/05/1950-28/06/1961 – thermograph in stevenson screen 2.2m above mown field (note downward step change in data)
29/06/1961-25/06/1993 – resistance measurement in stevenson screen 1.5m above mown field
26/03/1993-present day – electric sensor in dish cabin 1.5m above mown field (note step up).

So, how did the Hansomatic do?

-1950 step not adjusted
-1961 change is not visible in data
-1993 step not adjusted
-artificial trend introduced

I’ll try to do an adjustment graph a la Steve McI…

Data after Hansomatic adjustments

Note the creation of a non-existent trend in 1880-1950.

So that’s the Netherlands artificially warmed then…

spot the step change:

how do you get the unadjusted data?

Green used to mean naive & gullible or inexperienced in the old days, now it means messianic! Also the sailing expression “a bit green around the gills” used to refer to someone not used to sea travel, & was about to throw up! Was it not Cleopatra who said to Anthony in Shakespeare’s Anthony & Cleopatra, “ah, my salad days, when I was green in judgement”! Says it all really.

Generally, I work in the west country, Devon/Cornwall/Somerset/Dorset. If there is a list of stations available I would be happy to notify someone about any site visits I may be making so that I can be given a list of any nearby surface stations that could be photographed.

Where about are you? My local paper is the Herald Express too and I often write to it about AGW

I worked in a calibration/metrology lab, so I can answer question #2: Once a glass/mercury thermometer is properly calibrated, it really doesn’t need re-calibration [unlike digital thermometers, which drift and are usually much less accurate than mercury thermometers].

If you find a good mercury thermometer [lots of places sell them], a quick-and-dirty way to check accuracy [for a thermometer with a wide enough range] is to make an ice bath with 1/2 distilled water, and 1/2 distilled ice, crushed.

Mix the ice/water bath thoroughly for 30 seconds, put the thermometer in and carefully stir it in the bath for a minute.

After one minute, while holding the very top and keeping the bulb and the lower part of the thermometer in the water as much as possible [never touching the sides], you should read exactly 0 degrees C [or 32 degrees F if it's in Fahrenheit].

If the thermometer has the range, verify linearity by bringing a pot of distilled water to a boil, and repeating the reading. It should read 100 degrees C or 212 F, depending on type. Tests must be done at sea level.

The better scientific mercury thermometers are shipped factory calibrated, but you can do a search for a very inexpensive one by using the keywords “thermometer, mercury” and do your own calibration.

It’s fun keeping a daily log of temps using an accurate thermometer and comparing the result with your local GISS and NOAA record.

You can also buy a temperature datalogger from Anthony for under $60, which does automatic temp recording and downloads it into your computer: click

1. Are thermometers used at surface stations ever checked for accuracy?
2. Are they ever calibrated if they are in error?
And who is responsible?( I know. this is a 3rd question)

It seems tome that this could be as serious a problem as siting.

‘Coldest for at least ten years’ would put it better.
