The BBC World Service project Life At 50°C found that the number of extremely hot days every year, when the temperature reaches 50 degrees centigrade, has doubled since the 1980s. This returning series tells the stories of people on the frontline of climate change, sometimes made worse by conflict or pollution. Combining character-led stories, visual extremes and journalistic investigation, recent films were from South Sudan, Syria and Colombia. This new feature-length documentary is set in the coal country of Queensland, where life at 50°C is now a reality, but the economy is fuelled by coal mining. It’s an intimate portrait of lives inextricably linked to a new mine.
