Central England temperature

Although best efforts have been made by Manley and subsequent researchers to quality control the series, there are data problems in the early years, with some non-instrumental data used. According to Parker et al. (1992), up to 1814 Manley's data These problems account for the lower precision to which the early monthly means were quoted by Manley. Parker et al. (1992) addressed this by not using data prior to 1772, since their daily series required more accurate data than did the original series of monthly means. Before 1722, instrumental records do not overlap and Manley used a non-instrumental series from Utrecht compiled by Labrijn (1945), to make the monthly central England temperature (CET) series complete. For a period early in the 21st century there were two versions of the series: the "official" version maintained by the Hadley Centre in Exeter, and a version that was maintained by the late Philip Eden which he argued was more consistent with the series as originally compiled by Manley. The warmest year on record was recorded in 2022, with an average temperature of 11.15 degrees Celsius. This beat the previous 2014 record by 0.2 degrees and was almost 2 degrees over the 1961-1990 average. ==Trends revealed by the series==

During the eighteenth and nineteenth centuries, a cool period which coincided with cool winters and generally cool summers, the temperatures fluctuated widely but with little trend. From 1910, temperatures increased until about 1950, when they flattened before a sharp rising trend began in about 1975. The warmest decade on record is the 2010s (2011–2020) with a mean temperature of . Both the general warming trend and the hottest year on record at the time, 2014, have been attributed to human-caused climate change using observational and climate model-based techniques. This record was subsequently broken in 2022, when a mean CET of was recorded, above the 1961-90 average and breaking the 2014 record by nearly . ==Extremes==

Taking the 364-year period for the series as a whole: Hottest Coldest ==Mean, maximum and minimum temperatures==

Since 1878, the Central England temperature has recorded daily maximum and minimum temperatures; its daily mean records began in 1772. The tables below show the record average max/min for each season and each calendar month since 1878. Highest minimum Lowest minimum Highest maximum Lowest maximum ==Daily records==

Daily mean temperatures have been available since 1772, with max and min data available from 1878 onward.{{cite web |author1=Met Office U.K. |title=CET Record Breakers Highest mean Highest minimum Highest maximum Lowest mean Lowest minimum Lowest maximum ==See also==
