Met Office Should Put 2.5°C ‘Uncertainties’ Warning on All Future Temperature Claims

It is “abundantly clear” that the Met Office cannot scientifically claim to know the current average temperature of the U.K. to a hundredth of a degree centigrade, given that it is using data that has a margin of error of up to 2.5°C, notes the climate journalist Paul Homewood. His comments follow recent disclosures in the Daily Sceptic that nearly eight out of ten of the Met’s 380 measuring stations come with official ‘uncertainties’ of between 2-5°C. In addition, given the poor siting of the stations now and possibly in the past, the Met Office has no means of knowing whether it is comparing like with like when it publishes temperature trends going back to 1884.

There are five classes of measuring stations identified by the World Meteorological Office (WMO). Classes 4 and 5 come with uncertainties of 2°C and 5°C respectively and account for an astonishing 77% of the Met Office station total. Class 3 has an uncertainty rating of 1°C and accounts for another 8.4% of the total. The Class ratings identify potential corruptions in recordings caused by both human and natural involvement. Homewood calculates that the average uncertainty across the entire database is 2.5°C. In the graph below, he then calculates the range of annual U.K. temperatures going back to 2010 incorporating the margins of error.

The blue blocks show the annual temperature announced by the Met Office, while the red bars take account of the WMO uncertainties. It is highly unlikely that the red bars show the more accurate temperature, and there is much evidence to suggest temperatures are nearer the blue trend. But the point of the exercise is to note that the Met Office, in the interests of scientific exactitude, should disclose what could be large measurement inaccuracies. This is particularly important when it is making highly politicised statements using rising temperatures to promote the Net Zero fantasy. As Homewood observes, the Met Office “cannot say with any degree of scientific certainty that the last two years were the warmest on record, nor quantify how much, if any, the climate has warmed since 1884”.

The U.K. figures are of course an important component of the Met Office’s global temperature dataset known as HadCRUT. As we noted recently, there is ongoing concern about the accuracy of HadCRUT with large retrospective adjustments of warming in recent times and cooling further back in the record. In fact, this concern has been ongoing for some time. The late Christopher Booker was a great champion of climate scepticism and in February 2015 he suggested that the “fiddling” with temperature data “is the biggest science scandal ever”. Writing in the Telegraph, he noted: “When future generations look back on the global warming scare of the past 30 years, nothing will shock them more than the extent to which official temperatures records – on which the entire panic rested – were systematically ‘adjusted’ to show the Earth as having warmed more than the actual data justified.”
