Pope Francis

VATICAN CITY — Pope Francis called today for a bold cultural revolution to correct what he calls the “structurally perverse” economic system of the rich exploiting the poor that is turning Earth into an “immense pile of filth.”

In a sweeping manifesto aimed at spurring action in U.N. climate negotiations, domestic politics and everyday life, Francis explains the science of global warming, which he blames on an unfair, fossil fuel-based industrial model that he says harms the poor most. Citing Scripture and past popes’ and bishops’ appeals, he urges people of all faiths and no faith to undergo an awakening to save God’s creation for future generations.

It’s an indictment of big business and climate doubters alike.

“It is not enough to balance, in the medium term, the protection of nature with financial gain, or the preservation of the environment with progress,” he writes. “Halfway measures simply delay the inevitable disaster. Put simply, it is a matter of redefining our notion of progress.”

Environmental scientists said the first encyclical, or teaching document, on the environment could have a dramatic effect on the climate debate, lending the moral authority of the immensely popular Francis to an issue that has long been cast in purely political, economic and scientific terms.

Veerabhadran Ramanathan, a Scripps Institution of Oceanography scientist, said the encyclical would be a “game-changer in making people think about this.”

The energy lobby was quick to criticize the encyclical and its message.

“The simple reality is that energy is the essential building block of the modern world,” said Thomas Pyle of the Institute of Energy Research, a conservative free-market group. “The application of affordable energy makes everything we do — food production, manufacturing, health care, transportation, heating and air conditioning — better.”
