Why do weather records only begin in 1914?
Actually, they didn't. While the Met Office seems keen on saying "since records began in 1914" to describe any kind of record-busting weather (such as 2007's "wettest summer"), it has records that go back much further.
The England and Wales Precipitation series, which measures rainfall and snow, goes back to 1766, and the Central England Temperature series, which covers the temperature from the south Midlands to Lancashire, is the longest-running record in the world, dating from 1659.
"They were kept on a personal basis by amateur meteorologists," says Sancha Lancaster, a spokeswoman for the Met Office. "We have an archive here of thousands of people's weather diaries. Many don't just record the weather, they also record the effects on wildlife and plants. It takes years to quality-control them and put the data on to a computer."
