  2. Carbon dioxide - Wikipedia

    en.m.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is a chemical compound with the chemical formula CO2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature and at normally-encountered concentrations it is odorless..

  3. Carbon dioxide in Earth's atmosphere - Wikipedia

    en.m.wikipedia.org/wiki/Carbon_dioxide_in_Earth's_atmosphere

    In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of three main greenhouse gases in the atmosphere of Earth. The concentration of carbon dioxide (CO 2) in the atmosphere reach 427 ppm (0.04%) in 2024. [1]

  4. Carbon dioxide - Simple English Wikipedia, the free encyclopedia

    simple.m.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide (CO 2) is a chemical compound and is acidic. It is a gas at room temperature. It is made of one carbon and two oxygen atoms. People and most animals release carbon dioxide when they breathe out. Also, every time something organic is burnt (or a fire is made), it makes carbon dioxide.

  5. carbon dioxide, (CO 2), a colourless gas having a faint sharp odour and a sour taste. It is one of the most important greenhouse gases linked to global warming, but it is a minor component of Earth’s atmosphere (about 3 volumes in 10,000), formed in combustion of carbon -containing materials, in fermentation, and in respiration of animals and ...

  6. Greenhouse gas emissions - Wikipedia

    en.m.wikipedia.org/wiki/Greenhouse_gas_emissions

    Carbon dioxide (CO 2), from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the United States. The United States has higher emissions per capita.

  7. Carbon dioxide removal - Wikipedia

    en.m.wikipedia.org/wiki/Carbon_dioxide_removal

    Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.

  8. Definition, Emissions, & Greenhouse Effect - Britannica

    www.britannica.com/science/greenhouse-gas

    Greenhouse gas, any gas capable of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the phenomenon known as the greenhouse effect. Carbon dioxide, methane, and water vapor are the most important greenhouse gases.

  9. Carbon cycle - Wikipedia

    en.m.wikipedia.org/wiki/Carbon_cycle

    The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component of biological compounds as well as a major component of many rocks ...
