Greenhouse effect

 

The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet’s surface.

The name comes from an analogy with the warming of air inside a greenhouse compared to the air outside the greenhouse.

The Earth’s average surface temperature is about 33°C warmer than it would be without the greenhouse effect.

In addition to the Earth, Mars and especially Venus have greenhouse effects. The Earth receives energy from the Sun in the form of radiation.

The Earth reflects about 30% of the incoming solar radiation.

The remaining 70% is absorbed, warming the land, atmosphere and oceans.Image

Global warming is the result of the accumulation of gases such as carbon dioxide and methane in the atmosphere which  the heat can come in, but not so easily escape. This is especially burning of coal, crude oil and gasoline power plants, factories and cars that contribute to the buildup of gases in the atmosphere .
