According to the Met Office, September daily average maximum temperature in the UK was just over 17°C which makes it . . . . wait for it . . . . the 24th warmest since records began in 1910. UK Septembers became noticeably warmer after 1985, until 2006, then they started to get cooler again. 2019 merely continues that downward trend.
In the longer running Central England database, September 2019 mean temperature was 14.3°C, which puts it a stunning 68th warmest EVAH since records began, beaten only by 1729, 1795, 1760, 1780, 1731, 1730, 1750, 1708, 1678, 1680, etc. etc. etc. In fact, it looks like September in the 1700s was generally a much warmer month than it has been so far in the 21st century.
So I fully expect more universities and councils to declare a climate emergency with this latest horrifying revelation of how global heating is dramatically affecting the first month of Autumn in these Sceptred Isles and of course, it merely provides further justification, if any were needed, for Boris’s Bonkers Boiler Ban in 2020.
