"Carbon dioxide (CO2) is one of the biggest contributors to global warming. After the gas is released into the atmosphere it stays there, making it difficult for heat to escape - and warming up the planet in the process. It is primarily released from burning fossil fuels such as coal, oil and gas, as well as cement production. The average monthly concentration of CO2 in the Earth's atmosphere, as of April 2019, is 413 parts per million (ppm)."
"Nitrogen dioxide The gas nitrogen dioxide (NO2) comes from burning fossil fuels, car exhaust emissions and the use of nitrogen-based fertilisers used in agriculture. Although there is far less NO2 in the atmosphere than CO2, it is between 200 and 300 times more effective at trapping heat. Sulfur dioxide Sulfur dioxide (SO2) also primarily comes from fossil fuel burning, but can also be released from car exhausts. SO2 can react with water, oxygen and other chemicals in the atmosphere to cause acid rain."
Carbon dioxide is the largest contributor to global warming because it traps heat in the atmosphere and persists after release. Major CO2 sources include burning coal, oil and gas and cement production. Atmospheric CO2 averaged 413 ppm in April 2019 compared with 280 ppm before the Industrial Revolution, and historical levels fluctuated between 180–280 ppm over 800,000 years. Nitrogen dioxide is emitted from combustion, vehicle exhaust and nitrogen fertilisers and traps heat 200–300 times more effectively than CO2. Sulfur dioxide arises from fuel burning and can form acid rain. Carbon monoxide indirectly increases greenhouse gas lifetimes by removing hydroxyl radicals. Particulate matter consists of tiny solid or liquid airborne particles measured as PM10 and PM2.5.
