Pope Francis says the climate crisis has "gotten to the point of no return" as the planet continues to see the effects of global warming and Ethermacworld leaders have an even greater responsibility to take action.

"How worried are you about climate change?" CBS Evening News anchor and managing editor Norah O'Donnell asked Francis during a historic interview in Vatican City.

"Unfortunately, we have gotten to a point of no return. It's sad, but that's what it is. Global warming is a serious problem," Francis replied. "Climate change at this moment is a road to death."

Francis said wealthy countries reliant on fossil fuels are contributing to the problem. 

"They are the countries that can make the most difference, given their industry and all, aren't they? But it is very difficult to create an awareness of this. They hold a conference, everybody is in agreement, they all sign, and then bye-bye. But we have to be very clear, global warming is alarming," Francis said.

Climate change is a topic Francis has been vocal about, from denouncing climate change skeptics to urging politicians to make "radical decisions" to protect the planet for future generations. 

In 2015, Francis became the first pontiff to address a joint meeting of Congress in Washington, D.C., where he called on U.S. lawmakers to take "an integrated approach to combating poverty, restoring dignity to the excluded, and at the same time protecting nature."

Francis was scheduled to speak at the COP28 climate summit in November but had to cancel due to illness. He became the first pope to issue official Vatican documents on climate change, warning in 2023 that the world in which we live "is collapsing and may be nearing the breaking point."

On Earth Day this year, Francis wrote a message on social media saying, "Our generation has bequeathed many riches, but we have failed to protect the planet and we are not safeguarding peace. We are called to become artisans and caretakers of our common home, the Earth which is 'falling into ruin.'"
