Pope Francis on Monday urged environmental negotiators meeting in Paris to strike a deal to address climate change, warning that the world is "at the limits of suicide."
"I am not sure, but I can say to you 'now or never'," he told a group of reporters aboard the papal plane, en route home from Africa, according to Reuters. "Every year the problems are getting worse. We are at the limits. If I may use a strong word I would say that we are at the limits of suicide."
The pope's comments come as nearly 150 world leaders and others descend on Paris for a United Nations-sponsored environmental summit.
"I am sure they have the good will to do it. And I wish that it will be so, and I pray for this," he said.
He specifically cited problems associated with glacial melt in Greenland and rising sea levels in low-lying countries. Just a few days ago, Francis warned of a "grave environmental crisis" facing the world.
He is far from alone. Speaking at the summit, President Obama on Monday quoted Martin Luther King Jr. in warning that “there is such a thing as being too late.”
