Climate Change and Global warming

Global warming caused by human induced greenhouse gas emissions, as well as the resulting large-scale weather pattern alterations, are all part of climate change. Though there have been previous periods of climatic change, people have had an extraordinary impact on Earth's climate system and caused worldwide change since the mid-20th century. A long-term alteration in a place's temperature and usual weather patterns is referred to as climate change. Climate change can refer to a specific place or the entire globe.

CO2 and other air pollutants accumulate in the atmosphere, absorbing sunlight and solar radiation that has bounced off the earth's surface, resulting in global warming. Normally, this radiation would escape into space, but these chemicals, which may persist in the atmosphere for years to centuries, trap the heat and cause the earth to warm. Greenhouse gases are heat-trapping pollutants such as carbon dioxide, methane, nitrous oxide, water vapor, and synthetic fluorinated gases, and their impact is known as the greenhouse effect.
