Drought, Bushfires and Climate Change: The Hot Topic

The recent drought (2017-2019) but especially the horrific fires throughout Eastern Australia now called the Black Summer (~ August 2019-February 2020) has generated what could be called a “tipping point” in the broader Australian community discussion about climate change. In this talk we will examine in detail the facts around the drought and investigate how droughts are related to a warming climate. That investigation will focus on the underlying thermodynamic reason for warming during droughts. We then extend that investigation from drought to the subsequent Black Summer. Finally we will compare the facts we have established about drought and bushfires with projections made by climate models to investigate whether there is a reasonable expectation for more drought and bushfires with warming.
