Weather and climate don't stop at borders. Every single forecast you see, from the rainfall in your backyard to a track map of a moving cyclone is created from millions of observations, collected by people, satellites, radars and weather stations all around the world.
Through the World Meteorological Organization, countries share weather data and knowledge. This helps communities to prepare, respond, and stay safe when it matters most. By observing the weather and climate today, we can protect tomorrow.
