Junk Temperature Measuring Network Means the Met Office Cannot Prove There’s Been a “Dramatic Increase” in Temperature

Earlier this month, the Met Office claimed that climate change was causing a “dramatic increase in the frequency of temperature extremes and number of temperature records in the U.K.”. Given what we now know from recent freedom of information (FOI) revelations about the state of its ‘junk’ nationwide temperature measuring network, it is difficult to see how the Met Office can publish such a statement and keep a straight face.
The claims were the headline findings in the operation’s latest state of the U.K. climate report and are said to be based on “observations from the U.K.’s network of weather stations, using data extending back to the 19th Century to provide long term context”. That would be the network where nearly eight out of 10 stations are deemed by the World Meteorological Organisation (WMO) to have ‘uncertainties’ – i.e., potential errors – between 2-5°C. The same junk stations that provide ‘record’ daily temperatures often in the same places, such as the urban heat furnace that is Heathrow airport. The same junk measurements that the Met Office uses to claim collated measurements down to one hundredth of a degree centigrade.
The WMO rates weather stations by the degree of nearby unnatural or natural temperature corruption. Classes 4 and 5 have possible corruptions of 2°C and 5°C respectively and these account for the vast majority of the Met Office sites. The WMO suggests that Class 5 should not be used to provide an accurate measurement of nearby air temperatures, yet nearly a third of the Met Office sites are classified in this super-junk category. Only classes 1 and 2 have no uncertainties attached and only these should be used for serious scientific observational work. But, inexplicably, the Met Office has very few such uncorrupted sites. Even more worryingly, it seems to show no sign of significantly increasing the paltry number of pristine sites.
