Carbon dioxide - Wikipedia
Carbon dioxide (chemical formula CO 2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earths atmosphere as a trace gas.The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.
Liquid carbon dioxide - Wikipedia
Liquid carbon dioxide is the liquid state of carbon dioxide, which cannot occur under atmospheric pressure.It can only exist at a pressure above 5.1 atm (5.2 bar; 75 psi), under 31.1 °C (temperature of critical point) and above -56.6 °C (temperature of triple point).Its uses and applications include the extraction of virgin olive oil paste, fire extinguishers, and as a coolant.

Climate Change: Atmospheric Carbon Dioxide | NOAA Climate.gov
Carbon dioxide is the most important of Earth’s long-lived greenhouse gases. It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant and it stays in the atmosphere much longer.
Carbon Dioxide Absorbs and Re-emits Infrared Radiation ...
Molecules of carbon dioxide (CO 2) can absorb energy from infrared (IR) radiation. This animation shows a molecule of CO 2 absorbing an incoming infrared photon (yellow arrows). The energy from the photon causes the CO 2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon.

How Does Carbon Dioxide Affect the Environment? | Sciencing
Carbon dioxide is a naturally occurring greenhouse gas. Others include water vapor, methane and nitrous oxide. These gases help keep the Earth warm by absorbing the suns energy and by redirecting energy back to the Earths surface. An increase in the amount of carbon dioxide creates an overabundance of greenhouse gases that trap additional heat.
