ROME – As Pope Francis heads to the French port city of Marseille this weekend for a summit on the Mediterranean, two towering issues will loom especially large – the ongoing migration crisis, amid a new surge in arrivals to Europe, and the global climate agenda.

Francis will travel to Marseille Sept. 22-23 for a third edition of the Rencontres Méditerranéennes, or “Mediterranean Meetings,” following similar gatherings of political and ecclesiastical leaders in Bari in 2020 and in Florence in 2022.
