Religious leaders step up pressure for action on climate change

Faith leaders from an array of countries are urging decision-makers at the Paris climate talks to take action for moral as well as scientific or political reasons

Two years ago Yeb Sano, the Filipino government's lead climate negotiator, broke down in tears in front of the world's diplomats in Warsaw as typhoon Haiyan ripped through his home city of Tacloban, killing thousands of people.

This week he arrived at the Paris climate talks a changed man. No longer a star diplomat, he came on foot after completing a 58-day, 1,500km pilgrimage from Rome. He is now an official adviser to the archbishop of Manila.
