- Carbon dioxide - Wikipedia
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 a gas state at room temperature and at normally-encountered concentrations it is odorless
- What is Carbon dioxide (CO₂)? - myclimate
Carbon dioxide (CO₂) is a colourless and odourless gas that is a natural component of the air and part of the global carbon cycle It plays an important role in photosynthesis, in which plants convert CO₂ into oxygen
- Carbon dioxide | Definition, Formula, Uses, Facts | Britannica
carbon dioxide, (CO 2), a colourless gas having a faint sharp odour and a sour taste
- Understanding the basics of carbon dioxide - NOAA Research
Carbon dioxide is a gas produced when an organic carbon compound (such as wood) or fossilized organic matter (such as coal, oil, or natural gas) is burned in the presence of oxygen Carbon dioxide is removed from the atmosphere by “sinks”, such as absorption by seawater and photosynthesis by plants and plankton
- CO₂ emissions - Our World in Data
We can calculate the contribution of the average citizen of each country by dividing its total emissions by its population This gives us CO2 emissions per capita
- Carbon Dioxide - Earth Indicator - NASA Science
Carbon dioxide (CO2) is an important greenhouse gas Greenhouse gases trap the heat from sunlight, warming the planet Without any greenhouse gases, Earth would be too cold to support life But the more greenhouse gases there are in the atmosphere, the warmer the planet becomes
- Climate change: atmospheric carbon dioxide - NOAA Climate. gov
Each year, human activities release more carbon dioxide into the atmosphere than natural processes can remove, causing the amount of carbon dioxide in the atmosphere to increase The global average carbon dioxide set a new record high in 2024: 422 7 parts per million ("ppm" for short)
- Carbon Dioxide - Center for Science Education
Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere Without it, our planet would be inhospitably cold However, an increase in CO 2 concentrations in our atmosphere is causing average global temperatures to rise, disrupting other aspects of Earth's climate
