Greenhouse gas A greenhouse gas is a gas in an atmosphere that absorbs and emits radiant energy within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C, rather than the present average of 15 °C. In the Solar System, the atmospheres of Venus, Mars and ...

- This is the form of the sun's energy reflected off the earth's surface. Greenhouse gases then radiate heat energy back toward the earth. This heats the earth's atmosphere and ultimately contributes to increasingly warmer climates, a process known as global warming. Common greenhouse gases include carbon dioxide (CO2), chlorofluorocarbons (CFCs), methane (CH4), nitrous oxide (N2O), and tropospheric ozone (O3).

What are the operational definitions for carbon dioxide? CO2, or Carbon Dioxide, is a colourless and odourless gas. It is formed as a result of respiration by animals and by the decomposing of organic substances. It is then absorbed by plants and used in the process of photosynthesis (in which the plant releases oxygen back into the air).

Global Warming FAQ Why does CO2 get most of the attention when there are so many other heat-trapping gases (greenhouse gases)? Global warming is primarily a problem of too much carbon dioxide in the atmosphere. This carbon overload is caused mainly when we burn fossil fuels like coal, oil and gas or cut down and burn forests. There are many heat-trapping gases (from methane to water vapor), but CO2 puts us at the greatest risk of irreversible changes if it continues to accumulate unabated in the atmosphere. There are two key reasons why.

Greenhouse Gases and Temperature A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth. The greenhouse effect occurs as the gases reach Earth’s surface. As the short wave energy heats the surface, some of the longer wave energy radiates back into the atmosphere and back into space. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere.

How Global Warming Works The greenhouse effect happens because of certain naturally occurring substances in the atmosphere. Unfortunately, since the Industrial Revolution, humans have been pouring huge amounts of those substances into the air. Carbon dioxide (CO2) is a colorless gas that is a by-product of the combustion of organic matter.

Carbon dioxide in Earth's atmosphere Carbon dioxide in Earth's atmosphere. Carbon dioxide (CO2) is an important trace gas in Earth's atmosphere. CO2 is a major greenhouse gas and plays a vital role in regulating Earth's surface temperature through radiative forcing and the greenhouse effect. Carbon dioxide is an integral part of the carbon cycle, a biogeochemical cycle in which carbon is exchanged between the Earth's oceans, soil, rocks and the biosphere. Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis.

The Greenhouse Effect and Greenhouse Gases The atmosphere is made up of many different gases. Several gases have the ability to reflect the sun's energy radiating from the earth back to the earth as heat. The gases with this capability are known as greenhouse gases (GHGs). The main GHGs are water vapor, carbon dioxide, methane, and nitrous oxide. Without some level of GHGs in the atmosphere, the earth would be much colder than it is and life on this planet would be much different.

Why are CO2 emissions bad? There is sometimes some confusion about the difference between carbon and carbon dioxide and often they are lumped together. Carbon is the element that combines with oxygen to produce carbon dioxide. For every one molecule of carbon, there are two molecules of oxygen (hence CO2). Carbon on its own is not a greenhouse gas, but often CO2 is shortened to carbon for ease of reference.
