EXCLUSIVE: Met Office Uses Junk Temperature Measurements to Fill “World Treasure” 350-Year Temperature Record

n Climate: The Movie, William Happer, the former physics professor at Princeton, describes the Central England Temperature (CET) record as a “world treasure” since it provides continuous recordings from 1659 – over 350 years. It shows a rise just over 1°C from the depths of the Little Ice Age to the present day. These days, the CET is under the control of the politicised Met Office, keen to catastrophise weather and climate in the interest of promoting Net Zero. Recent revisions have retrospectively cooled the near past and boosted readings from the last 20 years. In addition, the Daily Sceptic can reveal that two of the three measuring stations currently used to add to this scientific treasure are taken from near-junk class 4 sites that come with official ‘uncertainties’ of up to 2°C.

Class 4 site Pershore College was added in 2006 and joined Stonyhurst, also class 4. The other site Rothamsted is a pristine class 1 site and is deemed to provide an accurate reading of the surrounding air temperature away from natural and artificial heat corruptions. Classification and ‘uncertainties’ by class are set by the World Meteorological Organisation (WMO). Quite why the Met Office can’t find three class 1 sites in the whole central England area is a bit of a mystery, although a clue might be provided by the recent freedom of information request the Daily Sceptic made to the organisation. We discovered that nearly eight out of 10 Met Office measuring stations across the United Kingdom were sited in near-junk class 4 and junk class 5. The latter class comes with WMO prescribed ‘uncertainties’ up to 5°C. Class 1 sites number just 24 and make up only 6.3% of the total.

At the very least, given the scientific importance of the CET, the Met Office could at least move the stations to more suitable nearby locations away from the disqualifying heat corruptions.

But if adding near-junk figures to the collection is not bad enough, the investigative science writer Paul Homewood last year discovered considerable tampering in 2022 with the recent CET record. He initially found that in version one, the summer of 1995 had been 0.1°C warmer than 2018. In version 2, the two years swapped places with 1995 cooled by 0.07°C and 2018 warmed by 0.13°C. Alerted to these changes, Homewood then analysed the full record from version 1 to 2, and the graph below shows what he found.

As can be seen, the adjustments up to 1970 are small with ups and downs offsetting each other. Homewood then found that the years from 1970 to 2003 had been cooled markedly, followed by significant rises to 2022. Homewood concludes that “unfortunately it is part of a much wider tampering with temperature globally – and the tampering is always one way, cooling the past and heating the present”. Given that we now know that the Met Office has been using class 4 statistics for two thirds of its database since 2006, the recent higher adjustments would seem to call for clarifying explanations from the state-funded Met Office.

But explanations from the Met Office are thin on the ground. It continues to promote a 60 second spike to 40.3°C at RAF Coningsby at 3.12pm on July 19 in 2022 as a U.K. temperature record, despite the known presence of three typhoon jets attempting to land around the same time. The record has become a national joke, even more so after the Daily Sceptic revealed that Coningsby is a class 3 site with an ‘uncertainty’ of 1°C. All that can be said is that at least Coningsby replaced the previous class 5 record set at Cambridge Botanic Gardens in 2019.
