An article in the NYTimes opens:
Pope Francis on Thursday called for a radical transformation of politics, economics and individual lifestyles to confront environmental degradation and climate change, as his much-awaited papal encyclical blended a biting critique of consumerism and irresponsible development with a plea for swift and unified global action.
The vision that Francis outlined in the 184-page encyclical is sweeping in ambition and scope: He described a relentless exploitation and destruction of the environment, for which he blamed apathy, the reckless pursuit of profits, excessive faith in technology and political shortsightedness. The most vulnerable victims are the world’s poorest people, he declared, who are being dislocated and disregarded.
It will be interesting to see what effect, if any, this encyclical will have on world affairs. The Pope, of course, is not the first public figure to speak out on climate, and it takes more than words to change the world.
But a papal encyclical is not a speech or a white paper, it is the official expression of an institution whose history stretches back two millennia and whose constitutions live on every continent and speak a multitude of tongues. It is thus transnational in scope in a way that perhaps no other document is. And it is a teaching document (emphasis mine):
Francis has made clear that he hopes the encyclical will influence energy and economic policy and stir a global movement. He calls on ordinary people to pressure politicians for change. Bishops and priests around the world are expected to lead discussions on the encyclical in services on Sunday. But Francis is also reaching for a wider audience when in the first pages of the document he asks “to address every person living on this planet.”
Will that happen? And not just on this Sunday, but on many Sundays after, Saturdays too, and Wednesday evenings.
In part we can measure the impact of Laudato Si (Praise Be to You) by the opposition it provokes.
Yet Francis has also been sharply criticized by those who question or deny the established science of human-caused climate change and also by some conservative Roman Catholics, who have interpreted the document as an attack on capitalism and as unwanted political meddling at a moment when climate change is high on the global agenda.
