Pope Francis warned of disastrous consequences if humanity does not immediately react to the threat of climate change, since the world has reached a “critical moment” and there is no time to waste.

“Dear friends, time is running out!” the pope told a group of participants in a Vatican-sponsored conference on energy transition Friday. “We cannot afford the luxury of waiting for others to come forward or of prioritizing short-term economic benefits. The climate crisis requires decisive action from us, here and now.”
Despite the pontiff’s frequent denunciation of a “politics of fear,” he seemed determined to paint as frightening a picture as possible of an impending climate apocalypse in order to incite people to action.
This conference “takes place at a critical moment,” Francis said. “Today’s ecological crisis, especially climate change, threatens the very future of the human family, and this is not an exaggeration. For too long we have collectively ignored the fruits of scientific analysis, and catastrophic predictions can no longer be viewed with contempt and irony.”
The pope’s words Friday went beyond sounding a general alarm and scorning climate-change skeptics. They also urged specific political action, most notably regarding penalties for carbon usage such as a carbon tax.
“A carbon pricing policy is essential if humanity wants to use the resources of creation wisely,” he said. “The failure to manage carbon emissions has produced a huge debt that will now have to be repaid with interest from those who come after us.”
The cost of carbon usage must be paid here and now by those who use it, and not deferred for future generations to cover, he proposed.
