FILE - In this Saturday, Jan. 17, 2015 file photo Pope Francis, wearing a yellow raincoat, waves to the faithful as he arrives in Tacloban, Philippines. Anxiety has so gripped American conservatives over Pope Francis' upcoming encyclical on the environment that you might think a pope had never before blamed fossil fuels for global warming. Or accused energy companies of hoarding the Earth's resources at the expense of the poor. Or urged the rich to consume less and share more. (AP Photo/Wally Santana)
