It acts as a blanket to keep the earth warm, the co2 particles reflect the suns rays back at us, so it gets hotter.
Greenhouse gases in the atmosphere interfere with the transmission of infrared rays into space.The primary atmospheric component that absorbs/blocks infrared (as well as microwave) radiation is water vapor, the amount of which remains relatively constant.Carbon dioxide is the dangerous greenhouse gas which has been building up rapidly since the Industrial Revolution when we began burning fossil fuels. This buildup is causing global warming and climate change.Clouds also prevent infrared radiation escaping into space.
- carbon dioxide is released in the atmosphere: - part of carbon dioxide in the atmosphere is absorbed by the biosphere - part of carbon dioxide in the atmosphere is absorbed by body of waters
Some of the gases found in our atmosphere which absorb infrared light are: carbon dioxide, methane, and water vapor. Gases found in our atmosphere which absorb ultraviolet light are ozone (O3) and oxygen gas (O2).
Carbon dioxide is totally transparent in the visible spectrum of light, but somewhat opaque at some infrared frequencies. Thus, it allows the sun's energy to pass freely through the atmosphere to the surface as visible light, but when this energy is re-radiated from the earth as infrared (heat) rays, some of them are absorbed by the atmospheric carbon dioxide, preventing them from escaping into space. When the atmospheric concentration of carbon dioxide increased, as is occurring now as a result of human activities (burning fossil fuels), it stops or absorbs more of the infrared radiation at these frequencies, making the air and the earth warmer. Thus we have global warming.
From the animals around it breathing oxygen and converting it to carbon dioxide.

Three planets, Earth, Venus and Mars, all have greenhouse effects from carbon dioxide (CO2) in their atmosphere.
Carbon dioxide (and other gases) creates a "blanket" around the earth trapping heat in the atmosphere. If these "greenhouse" gases were not there some of the heat would escape from the earth's atmosphere --------------------------------------------------------------------------------------- Carbon dioxide is transparent to visible light but opaque to infrared light (i.e. heat). When sunlight passes through the atmosphere and heats the surface of the earth the earth radiates infrared light. At low levels of carbon dioxide most of this infrared escapes to space, cooling the earth; but at high levels of carbon dioxide most of this infrared is reflected back down to the surface of the earth, keeping it hot.
If there wasn't we should all be dead right about now. Carbon dioxide is the most influential factor in the greenhouse effect of our planet. It allows visible light rays to pass into the atmosphere, however as they pass through it, many are refracted into infrared radiation (Heat/Thermal Energy). The infrared rays are now too weak to escape our atmosphere, and therefore heat has become trapped, allowing the atmosphere to remain at a temperature that is suitable for the life on this planet. Therefore, of course there is still carbon dioxide in the atmosphere.
Venus has the thickest carbon dioxide atmosphere.

Mars is the terrestrial planet with a thin carbon dioxide atmosphere. Venus also has an atmosphere of carbon dioxide, but it is very thick.

Carbon dioxide and other greenhouse gases are opaque to infrared radiation, therefore the less atmosphere there is for an infrared telescope to look through, the more you will be able to see.
