Natural greenhouse effect is the effect from water vapour in the air absorb and irradiate back the infrared radiation to earth. Effect from water vapour alone resulted to global temperature increase of 17 C and thus it is not the freezing earth.
The greenhouse gases present in the earths atmosphere are both naturally produced and man made. The natural greenhouse gases (methane, water vapour, carbon dioxide) make the Earth warmer than it would be without the Greenhouse effect (this allows it to be habitable). The addition of man made greenhouse gases (methane, carbon dioxide and a few others) increases the temperature past the natural levels. SO the greenhouse effect is both natural and a result of human activities. If you consider the opposite of a "natural effect" to be a "supernatural effect" resulting from gods, devils or ghosts -the greenhouse effect is natural with no supernatural contribution.
Natural gas is a greenhouse gas, methane, and when it is burnt it releases the other greenhouse gas, carbon dioxide.

the greenhouse effect
More greenhouse gases, whenever we burn fossil fuels (coal, oil and natural gas).
The term "greenhouse effect" is made up of two different effects: "Natural and Man-made". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earth's natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and natural gas). The three most significant green houses gases and the amount they contribute are water vapor (80%), carbon dioxide (6%) and methane (1%). Nature produces 99.7% of all green house gas emissions.

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.
Water vapour is a greenhouse gas that traps heat rising from the surface of the earth. In doing so it contributes to the natural greenhouse effect.
The natural greenhouse effect keeps the earth warm enough for life. The enhanced greenhouse effect is causing global warming.
