global average temperature

Global average temperature is a measure of the Earth's overall warmth, calculated by averaging temperatures from across the planet's land, ocean, and atmosphere. It provides a single value that reflects how the Earth's climate is changing over time. Small shifts in this average can significantly impact weather patterns, sea levels, and ecosystems. Monitoring this temperature helps scientists understand climate trends, identify warming caused by human activities like burning fossil fuels, and predict future climate changes. While it simplifies complex regional variations, the global average temperature is a key indicator of the Earth's overall climate health.
