Unearthing Australia’s climate history

Few people realise that snow was once a common occurrence for southern Australia’s climate. Historical records help document impacts of past weather extremes such as heatwaves, floods, droughts and even snow. Now scientists are using these fascinating resources to uncover more about Australia’s climate history and also shed light on modern severe weather events...

Previously unknown weather extremes discovered in new Adelaide record

Our analysis of recently transcribed historical data has picked up extreme events such as a week-long heatwave, bushfires, a dust storm, and severe storms that caused hail and flooding in 19th century Adelaide. Citizen scientists transcribed newly discovered historical daily weather observations from 1843 to 1856 for the Adelaide region.  The data show that 1847 … Continue reading Previously unknown weather extremes discovered in new Adelaide record

The longest daily weather record for Adelaide is now fully transcribed!

Our citizen science volunteers have helped to fill an eight-year data gap in Adelaide’s daily weather record, transcribing historical weather journals that cover the period 1843 to 1856. It took 1,103 volunteers 77 days to transcribe over 33,400 classifications on the citizen science platform, Zooniverse.  These newly transcribed observations will help link together historical and … Continue reading The longest daily weather record for Adelaide is now fully transcribed!

Historical climate data can improve our assessment of future climate risk

Australia is a land characterised by dramatic climate and weather extremes. Currently, our understanding of the nation’s climatic history is mostly confined to official records kept by the Australian Bureau of Meteorology that begin in 1900, despite the fact that observations are available from first European settlement of Australia in 1788. Colonial weather observations taken … Continue reading Historical climate data can improve our assessment of future climate risk

One month in: some preliminary results

Since our launch on 8 September 2020, more than 760 Zooniverse volunteers have digitised over 15,000 weather observations to help create Australia’s longest daily weather record. The project is now at the halfway point, with 50% transcribed and 50% still to go. ...
