The Winds of (Climate) Change

Larry Hamilton

On Thursday, June 18, 2015, Pope Francis made history in an encyclical — a papal letter that is distributed to all bishops in the Roman Catholic Church — entitled “Laudato Si,” in which he acknowledged that climate change is real. The 180-page document is the first to focus only on environmental issues. In it, the pope stated that climate change “represents one of the principal challenges facing humanity in our day,” and he hopes the letter will help us recognize “the appeal, immensity and urgency of the challenge we face.”

UNH Today asked some of UNH’s climate change experts about the implications of the encyclical. UNH sociology professor Larry Hamilton, who studies environmental sociology, says that Pope Francis’s words could influence people’s political views on climate change. “A lot of people who don’t have much information on climate change are not very set in their opinions,” he says, “so the pope’s statements have the potential to be influential.” However, not everyone’s opinions will change. Hamilton notes that more than 95 percent of scientists who study this topic already think that human-caused climate change is real and problematic, and the pope’s encyclical adds a moral dimension to this scientific consensus. He adds that those with “hardcore ideological views” that climate change is a hoax and conspiracy will not be swayed, but instead “will go to back to sources of information that tell them they’re still right.”

When asked about the effect the encyclical will have on the upcoming 2016 presidential election, Hamilton thinks the candidates are “not talking enough about science in general,” and that there is an “anti-science sentiment in the race.” He hopes that, regardless of whether the pope has changed people’s minds about climate change, his statements bring the conversation about climate, the environment and science back to the public’s attention.
