Water vapour, carbon dioxide, methane and nitrous oxide are the most important greenhouse gases.
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.
Yes, ozone is a greenhouse gas. Any gas with three or more atoms in their molecule are greenhouse gases.
Gas
It doesn't. Ozone is a greenhouse gas.
Carbon dioxide is the gas that is having the greatest impact on the enhanced greenhouse effect.
Water Vapor is the gas that is largely responsible for the natural greenhouse effect that has warmed the earth for millions of years.Carbon dioxide is the gas that is largely responsible for the present accelerated greenhouse effect that is causing global warming.
Water (vapor).
Gas and/or Atmosphere
The normal greenhouse effect which keeps the earth warm enough for life is caused largely by water vapour, with a small effect from carbon dioxide and methane.However, the greenhouse gas responsible for the present enhanced greenhouse effect is carbon dioxide, yes.
In terms of greenhouse effect, natural gas is more benign than coal or oil, because it provides a greater heating effect per unit of carbon dioxide produced. It is therefore not the major cause of the greenhouse effect.
Ozone is a greenhouse gas. However there is little connection between the greenhouse effect and the ozone layer.
Greenhouse gases have kept the planet comfortably warm for millions of years. This has been an advantage.Now, however, there is an excess of greenhouse gases (mostly carbon dioxide from burning fossil fuels). This extra greenhouse gas is causing an accelerated greenhouse effect which is causing global warming. This is a serious disadvantage!
