UN urges 'unprecedented' action on climate change

The Australian government says it will not phase out the use of coal-fired power, despite a new report saying its elimination is integral to limiting global warming. The report, from the United Nations, shows global temperature rises must not surpass 1.5 degrees Celsius, or there will be catastrophic problems for the world's ecosystems.
