What are carbon dioxide emissions?

carbon dioxide emissions (CO 2 ) occur when carbon dioxide is released into the atmosphere, whether naturally or through human activities such as burning fossil fuels. Carbon dioxide is a chemical compound composed of one carbon atom and two oxygen atoms that exist in the gas phase in the Earth's atmosphere. The atmosphere is a number of layers of gases that surround the ground. These gases are tied to the planet and prevents the Earth's gravity. The atmosphere is mainly composed of nitrogen and oxygen, but there are also many other gases in the atmosphere, including a small amount of carbon dioxide. However,

, carbon dioxide emissions and other greenhouse gases disrupted this balance. Greenhouse gas is an atmospheric gas that allows sunlight to go through the atmosphere to reach the ground. When the light hits the ground, some of them bounce back to the universe like infrared radiation or heat. Greenhouse gases capture this heat in the atmosphere, which is the world warmer in the phenomenonknown as a greenhouse effect. A certain amount of greenhouse gases is necessary to control Earth's climate and ensure that the planet is warm enough throughout the life, but too much warming can also endanger life.

natural processes that emit and remove carbon dioxide from the atmosphere in a complex ongoing exchange known as a carbon cycle. The processes responsible for carbon dioxide emissions are called sources and those that remove carbon dioxide are called sinks. Natural sources CO _{2 are breathing plants and animals such as human expenditure and volcanic eruptions. Natural sinks include photosynthesis of plants, during which plants remove carbon dioxide from the air to put sugars and store in plant biomass. The oceans are both sink and source, with tropical waters usually releasing carbon dioxide and colder ocean water absorbing carbon dioxide.}

in a healthyThe carbon cycle is canceled by the removal of carbon dioxide by removing the carbon dioxide, so there is no net change in carbon dioxide concentration. Human activities such as metal production, mineral production and fossil fuel burning have increased carbon dioxide emissions. Meanwhile, the ocean pollution and deforestation, the reduction of trees and other plants for wood, agriculture and the development of cities prevents the natural processes of the removal of carbon dioxide. Between the industrial revolution in 1700 and 2005, the concentration of carbon dioxide in the atmosphere increased by 35%, indicating that the sources in the carbon cycle exceeded sinks.

When fossil fuels such as coal, gas or oil are burned for energy generation, they release carbon in the form of CO _{2 . These fossil fuels are commonly burned for the production of residential and industrial electricity, create and move vehicles such as aircraft, trains, cars and boats. The processes of the production of lime, cement and ash of soda include chemicalIic reactions that transform chemicals in raw materials to create carbon dioxide emissions. Emissions CO 2 occur in a similar way in the production of metals such as iron, zinc and lead. Degradation of oil -based products and the production of chemicals, such as ammonia, also contribute to carbon dioxide emissions.}
