Reuters - Some U.S. scientists are expressing hope that Pope Francis' encyclical on global warming embracing the view that it is mostly caused by human activities will change public opinion in the United States, where the issue is highly politicized.
Texas Tech University climate scientist Katharine Hayhoe said the pope's document is important because more facts alone will not convince climate change skeptics.
"We have to connect these issues with our values," said Hayhoe, who described herself as an evangelical Christian.
Hayhoe said the pope's document will expose the "cognitive dissonance" in using religious arguments against global warming - for example, that God would not let this happen.
"The real reason you object to it has to come out of the closet," Hayhoe said.
