Date: 22 September 2025,
Time: 9:00-10:30 AM New York time (GMT-4)
Location: United Nations Headquarters
Convened by: The Secretary-General’s Climate Action Team, WMO, UNDRR, IFRC, ITU, UNEP, Brazil
The discussions will be presented in the main program at the Secretary-General’s Special High-level Event on Climate Action on 24 September and captured in a Chair’s Summary, reinforcing adaptation and resilience as key pillars of the COP30 Action Agenda.
As global temperatures rise, the frequency and intensity of extreme events are increasing. Floods, droughts, wildfires, storms and heatwaves are claiming millions of lives, devastating ecosystems and undermining social and economic development. The costs are growing exponentially.
Early Warning Systems (EWS) are one of the most eZective methods for reducing disaster deaths and losses. Countries with strong EWS have mortality rates nearly six times lower than those without, and even 24 hours’ advance warning can cut damage by up to 30%. Yet, as of March 2024, 108 countries reported having such systems in place. Significant gaps and challenges remain especially in vulnerable regions such as Africa, the LDCs and SIDS.
The United Nations Secretary-General’s Early Warnings for All (EW4ALL) initiative aims to ensure every person on Earth is protected by early warning systems by 2027. With two years remaining to meet this goal, it is critical to accelerate efforts on all fronts.
In addition, extreme heat has emerged as one of the deadliest, most far-reaching and often underestimated hazards of our time, with cascading impacts that disrupt health, labour productivity, food security, education and energy systems, particularly in urban contexts and informal economies.
This dialogue will bring together national governments, subnational authorities and regional partners, the private sector, philanthropy, Indigenous and youth representatives and civil society to take stock of progress and identify concrete, high-impact solutions that can be championed, replicated and scaled up. The goal is to mobilize political will and institutional momentum to deliver early warnings, heat risk prevention and reduction and long-term redesign, planning and anticipatory measures to protect lives and livelihoods in the age of extremes.The dialogue will:
- Take stock of progress and gaps in implementing Early Warnings for All (EW4All) and extreme heat resilience.
- Identify concrete, high-impact solutions ahead of COP30 in Belém.
- Mobilize political and institutional momentum to accelerate action on EW4All toward 2027.
- Identify how investments can be scaled for priority actions of the Secretary-General's Call to Action on Extreme Heat (social protection, labour, environment/science, low carbon cooling).
- Make links to upcoming political processes: WMO Congress, World Health Assembly, COP30 Beat the Heat Call to Action, ILO Tripartite process.
By invitation only.
