Vatican City, Jul 3, 2015 / 06:08 am (CNA/EWTN News).- Cardinal Pietro Parolin, the Vatican’s Secretary of State, has expressed his hope that Pope Francis’ recent environmental encyclical will have a strong impact on the United Nations' three major gatherings this year, and will inspire global powers not only to talk, but to act.

The cardinal spoke to CNA July 2, saying he hopes the effect of the encyclical on the U.N. meetings “will be especially concrete in climate change impact.”
