    • Weather and Climate
      Weather is the state of the atmosphere in a region over days and weeks, while climate is the average state of the weather over the longer term – decades, centuries, and millennia. Both are described by temperature, air pressure, cloudiness, moisture, wind speed, and wind direction. Many factors influence climate: the amount of sunlight, the condition of the atmosphere, the oceans, the solid Earth, the great ice sheets, and life itself. It is the complex interaction of all these influences that regulates climate and causes climate change.
