When did official weather records begin?
Amateur meteorologists have recorded the weather for centuries, but it was only in the mid-1800s that this became official. In 1854 the British government set up the Meteorological Department, which later became the Met Office. Several other countries set up national weather services to record and forecast the weather in this time period too. The problem was that they used different methods, which only gradually became standardised, hence the Met Office today only has reliable weather records from 1914. However, by analysing historical records, ice cores, fossils and other sources, scientists can estimate the weather conditions far further back in time.
