Donald Trump's decision to pull the USA out of the Paris Agreement on Climate Change attracted scorn from world leaders.
President Macron said that President Trump has, "committed an error for the interests of his country, his people and a mistake for the future of our planet". Chancellor Merkel said: "We need this Paris agreement to preserve our creation. Nothing can, or will, stop us from doing that."
Church leaders, equally, reacted with derision. The Vatican said for Pope Francis this was a "huge slap in the face" and a "disaster for everyone".
People in Ireland often look to their Church leaders to express how they feel in difficult times.
Leaders can be a prophetic voice on climate change. They can call for a change of direction, a repentance, from a path that leads to destruction.
President Trump's decision last week will further endanger the lives of millions of the most vulnerable people on earth.
Church leaders in Ireland need to be a voice for the voiceless, speak out for climate justice and support the Paris Agreement on Climate Change.
