00:59:02 Meeting Close
Summary: Anthropogenic climate change is shifting wildfire regimes more towards the extreme end of the fire behaviour spectrum. This can be seen in recent patterns of wildfire occurrence, with fires exhibiting more intense and erratic behaviours, burning outside of traditional seasonal windows, and manifesting more often as violent pyroconvective events with global reach and impact. This can also be seen in recent patterns of wildfire impact, with wildfires frequently wreaking devastation upon human and environmental assets at unprecedented levels. Examples include the destruction of entire townships in the western US — most recently in Los Angeles, mass fatalities and destruction of coastal townships in Greece, unprecedented number of deaths due to wildfire in Portugal in association with their first recorded instance of pyrocumulonimbus, record fire seasons in Canada including wildfires burning above the Arctic Circle, and of course the Australian Black Summer.
In this talk, Jason Sharples will discuss the scope of the extreme wildfire issue and highlight some of the insights that have been gained through the last two decades of research. These include a better understanding of the fundamental dynamics of wildfire under extreme conditions and the unique hazards that arise as a consequence. Professor Sharples will also discuss the global impacts of extreme wildfires and emphasise the need for improved fire management, highlighting some of the complexities that need to be addressed. Indeed, finding an effective management solution, which balances the many and varied aspects of wildfire risk, presents itself as a significant national and international challenge.
About the Presenter: Jason Sharples is a mathematical scientist at the University of New South Wales (UNSW), Professor of Bushfire Dynamics and founding Director of UNSW Bushfire. As an internationally recognised expert in dynamic wildfire behaviour and extreme wildfire development, his research has extensively influenced research, policy, and practice in Australia and internationally. He uses advanced mathematical and computational models to understand the dynamics of wildfire propagation and to pinpoint geograph... [truncated]
