Nearly one in three (29.2%) U.K. Met Office temperature measuring stations have an internationally-defined margin of error of up to 5°C. Another 48.7% of the total 380 stations could produce errors up to 2°C, meaning nearly eight out of ten stations (77.9%) are producing ‘junk’ or ‘near junk’ readings of surface air temperatures. Arguably, on no scientific basis should these figures be used for the Met Office’s constant promotion of the collectivist Net Zero project. Nevertheless, the state-funded operation frequently uses them to report and often catastrophic rises in temperature of as little as 0.01°C.
Under a freedom of information request, the Daily Sceptic has obtained a full list of the Met Office’s U.K. weather stations, along with an individual class rating defined by the World Meteorological Office. These CIMO ratings range from pristine class 1 and near pristine class 2, to an ‘anything goes’ or ‘junk’ class 5. The CIMO ratings penalise sites that are near any artificial heat sources such as buildings and concrete surfaces. According to the WMO, a class 5 site is one where nearby obstacles “create an inappropriate environment for a meteorological measurement that is intended to be representative of a wide area”. Even the Met Office refers to sites next to buildings and vegetation as “undesirable”. It seems class 5 sites can be placed anywhere, and they come with a WMO warning of “additional estimated uncertainties added by siting up to 5°C”; class 4 notes “uncertainties” up to 2°C, while class 3 states 1°C. Only 13.7%, or 52 of the Met Office’s temperature and humidity stations come with no such ‘uncertainty’ warnings attached.
The above graph shows the percentage totals of each class. Class 1 and 2, identified in green, account for just 6.3% and 7.4% of the total respectively. Class 3 identified as orange comes in at 8.4%. The graph shows the huge majorities enjoyed by the darkening shades of red showing classes 4 and 5. It is possible that the margins of error identified for classes 3, 4 and 5 could be a minus amount – if for instance the measuring device was sited in a frost hollow – but the vast majority are certain to be pushed upwards by heat corruptions.
