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 abnormal variations to the climate, and the effects of these variations on other parts of the Earth.
Global warming, as it is defined, can cause climate change. It is also notable that climate change can magnify the process and impact of global warming. Global warming is the warming of the lower atmosphere as a result of the increase of a number of gases that have been classified as greenhouse gases.
