A special report covering a hundred years of weather records from around Australia and what it means to the way we live. Dr Jonica Newby investigates what has happened to our weather over the past 100 years. Has the weather changed in the last 100 years or not? So, I'm heading on an investigation that's all about the simple facts. Real tidal gauges, actual temperature records. And this will be a proper weather report, going round Australia to the places you and I live and play. It's time to take the temperature of Australia. And, when it comes to weather, there's one organisation perfectly placed to guide me. They formed 100 years ago. They are the Bureau of Meteorology. Climate change.
