From 9 to 20 November 2026, Türkiye, Antalya, will host the 31st Conference of Parties (COP31) to the United Nations Framework Convention on Climate Change (UNFCCC).
At COP31, WMO will support Parties by providing authoritative scientific observations and information on the state of the global climate system and the state of the global observing system.
In a year in which record-breaking extremes have had a cascading effect on all levels of society and the economy, and against the backdrop of an unprecedented El Niño, WMO will put science at the heart of COP31. WMO will make the case for sustained investment in the observation and early warning systems that protect us all.
