More all-time temperature records have been smashed across Australia's interior as a climate change-fuelled heatwave grips the continent. Some of the hottest temperatures included the outback South Australian town of Maree, where the mercury nudged 49.8C. Senior meteorologist Dean Narramore said the blistering heat had broken dozens of temperature records across South Australia, NSW and Victoria over the course of a week. Mr Narramore said the records that had been broken were multigenerational, with some having stood for a century. "They're not just 10 or 20 years old, they're 30, 50, 80 and in some cases 100 years old," he said.
