1. CO2noun

   the chemical formula for carbon dioxide, a heavy odorless gas (CO2) formed during respiration and by the combustion or decomposition of organic substances; it is absorbed from the air by plants in photosynthesis. The formula itself, pronounced out, is often used instead of the full name, especially with reference to fire extinguishers using this gas for fire suppression; as, a CO2 extinguisher.

1. co2

   Carbon dioxide (chemical formula CO2) is a chemical compound 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. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change. Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, and seawater. When carbon dioxide dissolves in water, it forms carbonate and mainly bicarbonate (HCO−3), which causes ocean acidification as atmospheric CO2 levels increase.As the source of available carbon in the carbon cycle, atmospheric CO2 is the primary carbon source for life on Earth. Its concentration in Earth's pre-industrial atmosphere since late in the Precambrian has been regulated by organisms and geological phenomena. Plants, algae and cyanobacteria use energy from sunlight to synthesize carbohydrates from carbon dioxide and water in a process called photosynthesis, which produces oxygen as a waste product. In turn, oxygen is consumed and CO2 is released as waste by all aerobic organisms when they metabolize organic compounds to produce energy by respiration. CO2 is released from organic materials when they decay or combust, such as in forest fires. Since plants require CO2 for photosynthesis, and humans and animals depend on plants for food, CO2 is necessary for the survival of life on earth. Carbon dioxide is 53% more dense than dry air, but is long lived and thoroughly mixes in the atmosphere. About half of excess CO2 emissions to the atmosphere are absorbed by land and ocean carbon sinks. These sinks can become saturated and are volatile, as decay and wildfires result in the CO2 being released back into the atmosphere. CO2 is eventually sequestered (stored for the long term) in rocks and organic deposits like coal, petroleum and natural gas. Sequestered CO2 is released into the atmosphere through burning fossil fuels or naturally by volcanoes, hot springs, geysers, and when carbonate rocks dissolve in water or react with acids. CO2 is a versatile industrial material, used, for example, as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery, and as a supercritical fluid solvent in decaffeination of coffee and supercritical drying. It is a byproduct of fermentation of sugars in bread, beer and wine making, and is added to carbonated beverages like seltzer and beer for effervescence. It has a sharp and acidic odor and generates the taste of soda water in the mouth, but at normally encountered concentrations it is odorless.

1. co2

   CO2, also known as carbon dioxide, is a colorless, odorless gas that consists of a carbon atom bonded to two oxygen atoms. It is a byproduct of respiration, combustion, and decay of organic materials. CO2 is a greenhouse gas and plays a vital role in Earth's carbon cycle. It is also used in a number of commercial applications, such as carbonation in beverages and refrigeration.

Examples of co2 in a Sentence

1. Marcie Keever:

   We have to push them to issue a final (endangerment finding) and CO2 standard so we can have a conversation about what the standard should be, we wish the EPA wasn’t defaulting and deferring to ICAO, and instead would lead the way.

2. Hans Gruenfeld:

   A tax does not stimulate companies to make unprofitable investments, the Dutch are trying to get companies to suddenly move faster than elsewhere in Europe. There's a large chance that will only shift production abroad, without reducing CO2 emissions on an international scale.

3. Roger Hallam:

   I want to fully acknowledge the unimaginable suffering caused by the Nazi Holocaust that led to all of Europe saying ‘never again,' but it is happening again, on a far greater scale and in plain sight. The global north is pumping lethal levels of CO2 into the atmosphere and simultaneously erecting ever greater barriers to immigration, turning whole regions of the world into death zones.

4. Geosciences Professor Bogdan Onac:

   The interval also marks the last time the Earths atmospheric CO2 [carbon dioxide levels] was as high as today, providing important clues about what the future holds in the face of current anthropogenic warming.

5. George Shultz:

   Well, the CO2 that's in the atmosphere, it's going to stay there, but we can do a better job of keeping it down.
