The World Meteorological Organization plans to release its State of Climate update for 2026 on November 9, the opening day of COP31 in Antalya, Türkiye.
The agency’s conference page, updated November 6, places the release on Earth Information Day and describes it as a scientific assessment of climate indicators and impacts. The UN climate convention’s official listing confirms that the conference runs from November 9 to 20.
WMO says its work at the conference will focus on observations, climate information and early warning systems. Its announced events cover greenhouse-gas concentrations, heat and health, El Niño response and investment in the systems used to monitor hazards and warn communities.
The UN Environment Programme is also outlining implementation-focused events. Its published programme includes a Resilient Cities, Buildings and Cooling Pavilion and discussions on climate investment. A session on resilience for cities, infrastructure and water is listed for November 12, while finance activities include events on Finance and Trade Day on November 13.
The programmes show what the agencies intend to contribute before the negotiations begin. They do not establish a negotiated agreement or predict the findings of WMO’s unreleased update.
For readers following the summit, the immediate checkpoints are the November 9 scientific release, the conference’s confirmed daily programme and any formally adopted decisions. Figures and policy commitments should be assessed from those documents once published, rather than inferred from the advance agenda.
