The greenhouse effect

The atmosphere of the Earth contains the so-called greenhouse gases. The most important greenhouse gases are water vapor, carbon dioxide, methane, low altitude ozone, laughing gas (nitrous oxide) and fluorohydrocarbons. These absorb a part of the heat rays that otherwise would escape into space. Therefore the temperature rises. Through the natural greenhouse effect the average temperature on Earth is higher than it would be without the greenhouse gases. The man-made greenhouse effect, especially the massive release of CO2, causes a significant additional warming, that changes the entire climate.
