Most people think of early warning in terms of immediate and short-term concerns such as major weather events (hurricanes, cyclones, tornadoes), climatic variations (El Niño events, or droughts caused by lack of rainfall), or geo-physical events like earthquakes and tidal waves. These immediate and often unpredictable events require specific measuring and advisory systems.
Specifically targeted national and international organizations focus on the early warning of these events. UNEP/DEWA supports these activities and is directly involved in partnerships designed to ensure the more timely delivery of data and information on such natural hazards. However, UNEP/DEWA primarily focuses on identifying issues which take much longer to develop and might better be identified as "emerging environmental threats."
UNEP Global Environmental Alert Service (GEAS)
UNEP Global Environmental Alert Service (GEAS) is a mechanism for identifying, selecting and communicating early warning information on emerging issues to decision makers on a regular basis across UNEP's focus areas.
The Global Environmental Alert Service continuously scans the scientific literature, analyses results of earth observations and other data sources to produce widely distributed alerts, focussing on policy relevant environmental hotspots, environmental science, and near real-time environmental hazards in an easily understandable format.
It takes the pulse of the planet and enhances UNEP's ability to provide regular, science based updates to its member states and the international community on the status and trends of the global environment.
