Climate change and global warming

Climate change refers to the infinite variations in temperatures and weather conditions, including precipitation, temperature and winds. These changes can be natural, for example by variations in the solar cycle. Global warming refers to the persistent warming of the Earth caused by increased emissions of greenhouse gases. Climate change encompasses global warming but refers to the consequences of this change in the Earth's overall temperature. Warmer temperatures over time alter weather patterns and upset the usual balance of nature. This brings many risks to human beings and all other life forms on Earth. Global warming refers to the increase in global temperatures due primarily to increased concentrations of greenhouse gases in the atmosphere.
