The Record Hot UK Summer of 2025: Validation of the UKMO Methodology, but the Record Was Only in Tmin

UPDATE: Criticism of the Following Post from The Daily Sceptic

Due to the holidays, I just now saw the post at The Daily Sceptic criticizing my support of the UK Met Office methodology for combining temperature monitoring stations’ data. In retrospect, I should have made it clear that my comments that follow only address the UKMO method for combining stations of various lengths of record, how they “replace” closed stations with surrounding stations, and the use of urbanization-influenced stations. I do not mean to suggest that there are no other time-dependent changes (say, in instrumentation types) that could cause spurious warming in the record. Nor do I claim there are no time-dependent increases in urban heat island spurious biases in the record. I only address (1) the fact that a closed station being replaced with a surrounding station does not necessarily cause problems with long-term monitoring; (2) that the UKMO creation of a fine (1×1 km) grid of UK temperatures from extremely sparse data does not
