Pope Francis’ global call to combat climate change got mixed reviews Thursday from Mainers, who either embraced the pontiff’s plea for a “worldwide ecological movement” to rescue the environment or questioned his indictment of big business and climate deniers. A chemist before he became a priest, the pope issued the first-ever encyclical to explain the science of global warming and urge all people to address the “present ecological crisis” that threatens God’s creation. “It’s guidance to make us think of taking care of others and Mother Earth,” said Elizabeth Weber, a Great Diamond Island resident, on her way to noontime Mass at the Cathedral of the Immaculate Conception in Portland. In his encyclical letter, entitled “On Care For Our Common Home,” Francis says he hopes to influence ordinary people in their daily lives and decision-makers at critical United Nations climate meetings to be held this year.
