I liked this article about how they generate those 'wettest/coldest/sunniest/most orangey-yellow period since...' statistics* that are oft-quoted in the media.
*e.g. 'yesterday was the most orangey-yellow autumn day since orangey-yellowness began to be measured by satellite at the start of the Space Age**'
**Space Age: this began in 1957 when the first artificial satellite was launched (Sputnik); it ended in the 1970s and was followed in the US by the New Age*** and in the UK by 'The Age of the Train' .
***New Age: a broad cultural movement combining transendental meditation, spiritualism and talking out of your bottom.
