Forgotten: Historic hot temperatures recorded with detail and care in Adelaide

What I found most interesting about this was the skill, dedication and length of meteorological data taken in the 1800′s. When our climate is “the most important moral challenge” why is it there is so little interest in our longest and oldest data?

Who knew that one of the most meticulous and detailed temperature records in the world from the 1800′s comes from Adelaide, largely thanks to Sir Charles Todd. The West Terrace site in Adelaide was one of the best in the world at the time, and provides accurate historic temperatures from  “Australia’s first permanent weather bureau at Adelaide in 1856″. (Rainfall records even appear to go as far back as 1839.)  Lance Pidgeon went delving into the National Archives and was surprised at what he found.

If we want to understand our climate the records from the 1800′s in Adelaide are surely worth attention?

The BOM usually shows graphs like this one below starting in 1911. You might think you are looking at the complete history of Adelaide temperatures and that smoothed temperature is rising inexorably, but the historic records remain unseen. While “hottest” ever records are proclaimed in the media, few go hunting for older hotter records. Yet, one of the hottest temperatures recorded in Australia were recorded in 1828, and raging heatwaves with temperatures over 50C occurred in the 1800s. In 1896 a monster heatwave across the nation killed hundreds, and people were even evacuated on emergency trains.
