World Meteorological Day: The Sun, the Earth, and the Weather
Since 1950, the World Meteorological Day is observed every year on March 23. This year's theme is "The Sun, the Earth, and the Weather".
For over 4.5 billion years, the Sun has been driving the weather and delivering the energy that powers all lives on the Earth. Its heat ensures warmth and liquid water on the planet, which all living beings need to survive.
As climate changes and long-lived greenhouse gases accumulate, extreme weathers occur more often with devastating effects. Extreme cold, scorching heat, typhoons and snowstorms, all pose severe threats to the existence of humans and wildlife.
The Sun has endowed the Earth with much more than forests, water and diversified wildlife communities. All these elements make up our only home planet.
