A friend, Barry Horne, who kept meticulous weather records in his home village of Edlesborough in Buckinghamshire from 1969 until 1999, was not convinced about climate change.
He contended that the weather varied too much even over a 30-year period. Just in case he was wrong, however, he printed off his entire records and presented them to me so that if either of us lived long enough, the statistics might help with the answer.
