Francis’ visit to highlight climate change issue
USA Today - 09/17/2015
Whatever the outcome in Paris, the encyclical is likely to have far-reaching effects, though they may take years to be felt, says Northeastern University’s Matthew Nisbet, who studies the politics and communication of climate change. For moderate Republicans and Catholics who have voted Republican, the pope’s message could “elevate climate change into the box of five issues that they think about” in the voting booth, Nisbet says.
The encyclical signals that Francis himself – who approved and signed the text, though he probably didn’t write much of it, Bretzke says – is keeping his expectations realistic.
