We come from the land, and we go back to the land. Aboriginal people have been on this land for at least 60,000 years in some of the most extreme conditions on Earth and survived. And over the last 230 years, the most catastrophic events have occurred to this land because people didn't listen to ancient Aboriginal cultures and knowledge. So my question is, if people were able to look after this place for 60,000 years and thrive, what have we done to ensure that we have a healthy fit world for the next 60,000 years?

Author of Trusting Judgments: How to Get the Best Out of Experts

The idea of expertise and expert judgment has been around and has been something that society depends upon for a long time, but there have been no serious empirical explorations of who's an expert, what a domain of expertise is, and what sort of frailties are experts susceptible to. Those things haven't been addressed in an empirical way until the last 30 years. Some of this work began in the fifties with Kahneman and Tversky. They began to explore the things that make people misjudge risky situations, and that led to a body of research on who makes good judgments and under what circumstances for things that might affect us in various ways.

We're really starting to witness serious climate extremes that can no longer be ignored. And the IPCC, one of our key conclusions to that report was that effectively the human fingerprint on the climate system is now undeniable. It is now an established fact that we have warmed every single continent, every ocean basin on the planet. And again, that's a pretty serious thing to contemplate that human activity from the burning of fossil fuels and the clearing of land has led to this energy imbalance in the earth system, which is leading to a rapidly shifting climate.
