It describes changes in the state of the atmosphere over time scales ranging from decades to millions of years. These changes can be caused by processes inside the Earth, forces from outside (e.g. variations in sunlight intensity) or, more recently, human activities.
Climate change is any significant long-term change in the expected patterns of average weather of a region (or the whole Earth) over a significant period of time. Climate change is about non-normal variations to the climate, and the effects of these variations on other parts of the Earth. Examples include melting of the ice caps at the South Pole and North Pole. These changes may take tens, hundreds or perhaps millions of years.
In recent usage, especially in the context of environmental policy, climate change usually refers to changes in modern climate (see global warming).
