Pope Francis declares 'climate emergency' and urges action

Addressing energy leaders, pope warns of 'catastrophic' effects of global heating

Pope Francis has declared a global "climate emergency", warning of the dangers of global heating and that a failure to act urgently to reduce greenhouse gases would be "a brutal act of injustice toward the poor and future generations".

He also endorsed the 1.5C limit on temperature rises that some countries are now aiming for, referring to warnings from the Intergovernmental Panel on Climate Change of "catastrophic" effects if we crossed such a threshold. He said a "radical energy transition" would be needed to stay within that limit, and urged young people and businesses to take a leading role.
