What Is the Greenhouse Gas Effect?

Greenhouse gas is defined as gases in the atmosphere that absorb and emit radiation with the thermal infrared range. The greenhouse gas effect refers to the change in the Earth's steady temperature.

Significance

Much like a greenhouse does for growing plants, the gases in the Earth's atmosphere keep the planet at a steady temperature.

Function

When the sun's rays enter the Earth's atmosphere, the energy is filtered through the greenhouse gases. A portion of the sun's energy heats up the planet. It is then sent back into the atmosphere.

Effects

Without the work of the greenhouse gas effect, the Earth's temperature would become too cold. If the greenhouse gas becomes thicker, the planet will become too warm.

Time Frame

Since the Industrial Revolution began in the 1700s, greenhouse gases have become thicker because pollution from factories.

Sources

The greenhouse gas effect is able to maintain its concentration of gases because of the natural emissions from things on Earth. Organic decay produces carbon dioxide. Natural oil and gas extraction produce methane. Forests and grasslands produce nitrous oxide.

Warning

When humans, either directly or indirectly, alter the structure of the important gas-producing systems, the blanket of greenhouse gas is compromised.
