Antonio Guterres made his plea as thousands of participants descended on a sprawling expo centre in the Turkish Mediterranean city of Antalya for the UN's annual two-week climate conference.

The summit comes after a year of punishing heatwaves in Europe, major wildfires in Indonesia and catastrophic floods in Nepal, with an exceptionally strong El Nino weather phenomenon fuelling more climate chaos.
