The Sprigg lecture series provides visitors with access to the latest research and thinking around scientific and cultural discoveries at a local and global level and to engage with scientific ideas that affect them and their world, now and in the future.

These free lectures commemorate the life of Dr Reg Sprigg AO, a remarkable South Australian geologist who discovered the world’s oldest fossilised animals in the Flinders Ranges in 1946, now internationally recognised as the Ediacara fossils.

Sprigg lecture series: Prof. John Tibby - Mega-droughts and flooding rains

Tuesday 5th June, 6pm – 7pm (the Museum will open to guests at 5:30pm, with a complimentary glass of wine available prior to the talk)

Book here.

 

Mega-droughts can last two or more decades, and have been responsible for the demise of at least five major civilisations in the past 1500 years. Extreme events such as prolonged droughts or massive floods are occuring ever more frequently, and predictions indicate that there's more to come. Can these events occur naturally, or are they always human-made? Can we reconstruct and learn from previous climates?

In this special Sprigg lecture for World Environment Day, Professor John Tibby will focus on evidence for hydroclimate variation in the 10,000 years since the end of the last ice age, a period with similar climate conditions to the present. He uses evidence from indicators preserved in fossil leaves, pollen and algae, to infer the past hydroclimate. These sediments reveal evidence for substantially more extreme climate events including mega-droughts longer than any in the historical record.

Professor John Tibby currently lectures at the University of Adelaide, and has previously lectured at Loughborough University and University College London. He has been a research associate at Monash University studying the environmental history of the Maritime Continent. His work with the University of Adelaide focuses on the sources and effect of nutrient pollution in the upper Torrens River Catchment.
