Climate actions
Early warning systems (EWS) are key elements for climate change adaptation and disaster risk reduction that aim: The significance of an effective early warning system lies in the recognition of its benefits by local people. Early warning systems include detection, analysis, prediction, and then warning dissemination followed by response decision-making and implementation. Such systems are in place, in many parts of the world, to monitor, forecast and warn people about e.g. tropical cyclones, floods, storms, tsunami, avalanches, tornadoes, severe thunderstorms, volcanic eruptions, extreme heat and cold, forest fires, drought, etc. To be effective and complete, an early warning system needs to comprise four interacting elements namely: risk knowledge, monitoring & warning services, dissemination & communication and response capability. Critical issues include: limited geographical or temporal resolution, lack of evaluation of predictive validity, incorrect use of an early warning system that could result in significantly increasing the impacts for the affected population, public understanding of and trust in the system.
