CASTEL GANDOLFO, Italy, July 9 (Reuters) – Pope Leo has interrupted  a two-week vacation on Wednesday to celebrate a special Mass exhorting Catholics to exercise care for creation, in the Vatican’s second major appeal in a week for the world to address global climate change.

“Today … we live in a world that is burning, both because of global warming and armed conflicts,” the pontiff said in a small outdoor ceremony in Castel Gandolfo, an Italian hill town about an hour’s drive from Rome where he is spending his holiday.
