Global Warming is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
Global warming occurs when carbon dioxide (CO2) and other air pollutants collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally this radiation would escape into space, but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. These heat-trapping pollutants—specifically carbon dioxide, methane, nitrous oxide, water vapor, and synthetic fluorinated gases—are known as greenhouse gases, and their impact is called the greenhouse effect. Some factors leading to the cause of global warming include;
1. Burning fossil fuels
When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere.

2. Deforestation & Tree-Clearing
Plants and trees play an important role in regulating the climate because they absorb carbon dioxide from the air and release oxygen back into it. When vegetation is removed or burnt, the stored carbon is released back into the atmosphere as CO2, contributing to global warming.

3. Agriculture & Farming
Animals, livestock like sheep and cattle, produce methane, a greenhouse gas. When livestock grazed at a large scale, the amount of methane produced is a big contributor to global warming.
These are among a few causes of Global Warming.
