Global Status of Multi-Hazard Early Warning Systems 2025
Launched at the COP30 Belém Climate Summit, the Global Status of Multi-Hazard Early Warning Systems 2025 report provides a snapshot of progress in the implementation of the UN's flagship Early Warnings for All (EW4All) initiative, which aims to protect every person on Earth with an early warning system by 2027.
The report reveals measurable progress, with 119 countries, or 60% of all countries, now reporting the existence of a Multi-Hazard Early Warning System. This is a 113% increase over the past 10 years. However, coverage gaps persist, especially among small island developing States, as only 43% of them reported having systems in place.
Comprehensiveness scores for system capabilities have increased by an average of 45% across all regions. Africa has seen the greatest progress since 2015, with a 72% increase in the comprehensiveness, but it remains the region with the lowest scores.
It also places special focus on emerging hazards that are intensifying, including extreme heat, wildfires, and glacial lake outburst floods, which pose new threats that many existing warning systems are not equipped to handle.
The report urges governments to unite around achieving universal early warning protection by accelerating targeted financial investments, strengthening risk governance, and ensuring that all systems are co-developed with local communities to ensure no one is left behind.
