The Greenhouse Effect

The greenhouse effect is something, what is caused  by several gases called Greenhouse gases. The main type of gas is carbon dioxide. There is a lot of water vapor(hidrogen dioxide) and nitrous dioxide in the atmosphere too.

The picture is explaining the Green House effect in detail. The main thing what is going on, is that we produce  greenhouse gas in factories and also generate it with cars, and so on. This gas traps the solar energy inside the atmosphere, raising the temperature significantly. Since the beginning of the Industrial Revolution, the burning of fossil fuels has contributed to a 40% increase in the concentration of carbon dioxide in the atmosphere from 280 ppm to 397 ppm. Here is a % amount of contribution to the greenhouse effect by various gases.

Gas	Formula	Contribution (%)
Water vapor	H2O	36 – 72%
Carbon dioxide	CO2	9 – 26%
Methane	CH4	4 – 9%
Ozone	O3	3 – 7%

Heres another picture of how the greenhouse effect works:

So it's possible, that in several years, the time it takes for greenhouse gases to leave the atmosphere, will increase significantly, and therefore the temeperature too.
