Carbon dioxide and methane. Human activity is releasing more and more of these gases from the burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide (CO2) from the atmosphere).
So the natural greenhouse effect that has kept the earth warm for millions of years is being enhanced into an accelerated greenhouse effect.
carbon dioxide (CO2) and Methane (CH4).
The greenhouse gases contribute to the greenhouse effect. Greenhouse gases are inescapable.
The greenhouse effect warms the gases in the atmosphere.
Greenhouse Effect
it allows solar radiation to penetrate to the surface!
The rain-forests are important to the environment because they filter gases, such as carbon and methane, common greenhouse gases, in the atmosphere. Without them, there is nothing to stop the greenhouse gases in the atmosphere. These gases then trap more heat, adding to global warming. THE GREENHOUSE EFFECT!

The greenhouse effect is the natural process by which greenhouse gases keep the earth's temperature at a comfortable level suitable for human existence. The enhanced greenhouse effect is the increase in greenhouse gases that is leading to global warming. The term "enhanced greenhouse effect" is also referred to as the "anthropogenic greenhouse effect" and is the idea that humans may have an effect on global climate. It is also referred to as the "runaway greenhouse effect".
The greenhouse effect is the natural way that the Earth keeps warm. Too many extra greenhouse gases turn the greenhouse effect into an enhanced greenhouse effect. The enhanced, or accelerated, greenhouse effect is causing global warming.
There is a greenhouse effect on Earth because three-atomed gases in the atmosphere retain heat and ensure that the earth stays warm. Other examples of a greenhouse effect are the atmospheres of Venus and Mars. Mercury has an atmosphere but has no greenhouse effect, as the main gases (hydrogen, helium and oxygen) are not greenhouse gases. So Mercury is a non-example of the greenhouse effect. The moon is also a non-example, as it has no atmosphere at all.
