I believe that climate change is one of the biggest threats to human civilization of our time, if not the biggest. So in that sense I’m glad that Pope Francis’s upcoming encyclical will apparently be a strong endorsement of our responsibility to address it.
Still, I find the excitement around this encyclical to be a bit odd. There seems to be an assumption that this will somehow be a game-changer in galvanizing support for climate action. But if there’s one thing we know about American politics at least, it’s that Catholics’ political behavior is, in general, not detectably different from non-Catholics. Catholic voters as a group vote pretty much the same as the general electorate, and there is no cohesive ideological stance shared by Catholics as such. Among politicians, liberal Catholics like Joe Biden and Nancy Pelosi freely disregard the church’s teaching on same-sex marriage and abortion, while conservative Catholics like Rick Santorum and Paul Ryan ignore its views on the environment and economic justice. Everyone’s a cafeteria Catholic, essentially.
Now, people have come up with various ways to nuance this or have deployed subtle arguments about why it’s OK to disagree with the church or the pope on some issues, while others are non-negotiable. Which, as part of an intra-Catholic debate seems totally legitimate. But it also reinforces the point that people will emphasize the parts of the church’s teaching that line up with their preexisting political commitments. Liberals will talk a lot about social justice and the environment, while conservatives will keep emphasizing gay marriage and abortion. What I don’t see a lot of evidence for is that people are going to change their mind on a big issue like climate change based on what the pope says.
Of course I could be wrong, and in this case I hope I am!
