What is climate change? Climate is usually defined as the average weather in a place. It includes patterns of temperature, precipitation (rain or snow), humidity, wind and seasons. Climate patterns play a fundamental role in shaping natural ecosystems, and the human economies and cultures that depend on them.
For global climate change during Earth's history, see Climate change. Global change refers to planetary-scale changes in the Earth system. The system consists of the land, oceans, atmosphere, polar regions, life, the planetâs natural cycles and deep Earth processes. These constituent parts influence one another.
