Australia formally signs up to climate agreement

The federal government has formally signed up to the Paris Agreement on climate change, joining more than 100 other countries committing to help curb global carbon emissions. The move comes despite the United States' election of climate sceptic Donald Trump, who has indicated he will overhaul that country's climate policies. The United States is the world's second-largest emitter.
