The atmospheric gases carbon dioxide, methane and nitrous oxide are all greenhouse gases that help to heat the Earth.
oxygen and carbon dioxide
Greenhouse gases help keep the earth's temperature at a comfortable level suitable for human existence. When we increase the atmospheric concentration of greenhouse gases above their natural level, this leads to global warming, in other words higher average temperatures across the globe.
the reason is that certain gases, dubbed greenhouse gases by us scientists have the ability to trap heat radiation from the suns rays in our atmosphere, heat that would normally dissipate into the vacuum of space. those gases include methane and carbon dioxide. when in suitable amounts those gases are actually beneficial to life on earth as without them the earth would be far too cold to support any interesting life. unfortunately human activities are releasing huge amounts of said greenhouse gases into the air, meaning that more heat rays are trapped and hey presto, the world heats up
Stratospheric ozone
The greenhouse effect is simply the atmosphere's ability to retain heat. This is caused by gases, which we call greenhouse gases. These gases trap heat, rather like greenhouses trap heat to help grow plants in cold climates.
There are several gases that are classed as greenhouse gases.They are:water vaporcarbon dioxideozonemethanenitrous oxideCFCsEnergy from the sun heats the earth's surface and atmosphere, which drives the earth's weather and climate. The earth's surface radiates some of this solar energy back into space. These atmospheric gases are called greenhouse gases because they help trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse.

A green house for plants helps to keep in certain moistures and certain gases with in the vacinity. also keeps all your plants nice and warm in the winter! so, the gases hold in certain heat
A valve that brings atmospheric air into the furnace exhaust to help expel the exhaust gases.
Greenhouse gases in the atmosphere help trap heat emitted from the Earth, otherwise the temperature of Earth's surface would be below zero.

The greenhouse effect is capturing heat in the atmosphere. It does this with the help of various greenhouse gases, especially carbon dioxide and methane. Because human activities are putting much more of these gases into the atmosphere without any signs of slowing, the atmosphere now has too much heat trapped in it.
Stratospheric ozone
The atmospheric shield which protects Earth from the radiation of the sun is the Earth's own magnetic field. Also, the ozone layer (O3 particles in the stratosphere) help to filter Ultraviolet light.
