Early Warning Is Really a Governance Problem

The UN conversation on heat, cities and El Niño contains a deceptively simple insight: the value of an early-warning system is not the sophistication of the forecast, but whether it changes what people and institutions do before the hazard becomes a crisis. WMO Secretary-General Celeste Saulo reduces preparedness to three practical questions – what threshold triggers action, who has the authority to act, and which vulnerable groups must be reached first and those questions move early warning immediately from meteorology into governance. The UK example makes the mechanism visible: meteorological and health agencies did not simply exchange information during the 2022 heat event; they had already built relationships, decision protocols and weeks of preparation so that a red warning could trigger action across health, social care, infrastructure, government and civil society. UN-Habitat adds another layer by arguing that warnings cannot substitute for the longer institutional work of safer housing, better urban form, greener and bluer cities, and stronger capacity in informal settlements, meaning resilience has to operate simultaneously at the level of immediate response and structural change. What connects these examples is a pattern I keep returning to: information becomes protective only when it can travel through a chain of trust, authority, capability and finance into action. This is why the “last mile” of early warning may be less about transmitting one more message and more about building shared resilience—the relationships and institutional arrangements through which meteorologists, health systems, city governments, community organisations and households know what they are expected to do when a threshold is crossed. The harder question for Early Warnings for All is therefore not simply whether everyone can receive a forecast, but whether the surrounding system has already agreed what happens next.
