World leaders urged not to COP out of climate action in Madrid

Political leaders, diplomats and negotiators are meeting for two weeks of talks amid a growing sense of urgency.

It began with the bang of a gavel in a cavernous hall on the outskirts of Madrid.

The latest round of UN climate talks. More than 25,000 people, more than 50 heads of state.

And an urgent call to action from the UN Secretary General, Antonio Guterres.
