Carbon dioxide - Wikipedia
Carbon dioxide is a chemical compound with the chemical formula CO 2. 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..
Carbon dioxide | Definition, Formula, Uses, & Facts | Britannica
Carbon dioxide, a colorless gas having a faint sharp odor and a sour taste. It is a greenhouse gas, but it is a minor component of Earth’s atmosphere, formed in combustion of carbon-containing materials, in fermentation, in respiration of animals, and employed by plants in the photosynthesis of carbohydrates.
Carbon Dioxide - Climate Change: Vital Signs of the Planet
Carbon dioxide (CO 2) is an important heat-trapping gas, also known as a greenhouse gas, that comes from the extraction and burning of fossil fuels (such as coal, oil, and natural gas), from wildfires, and natural processes like volcanic eruptions.
Climate Change: Atmospheric Carbon Dioxide
The global average carbon dioxide set a new record high in 2023: 419.3 parts per million. Atmospheric carbon dioxide is now 50 percent higher than it was before the Industrial Revolution.
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.
How Exactly Does Carbon Dioxide Cause Global Warming?
Over the past few years, we’ve received a lot of questions about carbon dioxide — how it traps heat, how it can have such a big effect if it only makes up a tiny percentage of the atmosphere, and more.
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.
Global warming - Carbon Dioxide, Climate Change, Greenhouse Gases ...
Of the greenhouse gases, carbon dioxide (CO 2) is the most significant. Natural sources of atmospheric CO 2 include outgassing from volcanoes, the combustion and natural decay of organic matter, and respiration by aerobic (oxygen-using) organisms.
