Swedish teenager Greta Thunberg warns COP25 talks in Madrid, Spain: 'Our leaders are not behaving as if we are in an emergency.'
Activist Greta Thunberg has criticised governments at the UN climate talks for avoiding taking action to cut greenhouse gas emissions.
In a speech at the COP25 talks in Madrid, Spain, the Swedish teenager, who inspired the worldwide school strikes for climate movement, said: "Our leaders are not behaving as if we are in an emergency."
She said the science showed that, at the current rate of emissions, the world is set to use up the whole "carbon budget" - the amount of pollution that can be put into the atmosphere and still keep global warming to 1.5C - in eight years.
Countries previously committed to curbing global warming at "well below" 2C above pre-industrial levels and to pursue efforts to keep temperature rises to 1.5C in the Paris Agreement secured in 2015.
