Stuart Browning (Risk Frontiers) unpacks what a Super El-Nino means for the Australian seasonal outlook and the climate drivers in play this summer, including El Niño, the IOD and SAM.  He will also share insights into climate related events of the last year including glacier melting and heat stress.

Tom Mortlock (Aon) shares insights with a global view: what ENSO has historically cost insurers around the world, why the oceans are increasingly driving the outlook, and the uncertainty a slowing AMOC introduces into extreme-weather and climate scenario analysis.
