ROME, April 21, 2017 (LifeSiteNews) -- Pope Francis made a climactic appearance in a National Geographic film about “global warming” that was narrated by Hollywood star Leonardo DiCaprio and released on DVD this week.

The film, titled Before The Flood, contained a line-up of left-leaning activists renowned for pushing the theory of man-made global warming. The list included Ban Ki-moon, Bill Clinton, Oprah, Elon Musk, John Kerry, and Barack Obama. 

The film's climactic ending shows DiCaprio, the United Nation’s Messenger of Peace, being received at the Vatican by Pope Francis. According to the film, they spoke about the necessity of the “world community” accepting the “science” behind so-called climate change. The meeting took place in January 2016. 

“One of the most important spiritual leaders on the planet…has now called upon the world community to accept the modern science of climate change. A pope has never done anything like this in history,” related DiCaprio in the film.
