The to the right, shows a yellow line in the shape of a circle around the earth. This circle is the greenhouse of the earth. It is formed by greenhouse gases. The greenhouse effect causes many of the sun rays entering the earth to reflect back onto the earth again as they try to leave. The reason they get reflected back is because greenhouse gases get hit by the sun rays as they try to escape, but instead of breaking through, the sun rays reflect, then becoming heat, making the earth warmer.

There are four main greenhouse gases in the atmosphere: Carbon dioxide (emitted from fossil fuels, decay of biomass, etc.), methane, nitrous oxide, and f-gases.
Fluorinated gases (f-gases), HFC's, PFC's, NF3, SF6, have been increasing ever since 1990. F-gases also destroy ozone, letting in more ultraviolet sun radiation than we need. The graph below shows the amount of fluorinated gases emitted from the United States, starting in 1990, until now.

A very large factor (57%) of the gases polluting the atmosphere is a very well known gas: carbon dioxide. One way carbon dioxide is released, is from fossil fuels. Fossil fuels are organic materials that have been exposed to heat and pressure for so long that they become coal, oils, petroleum (petrol), natural gases, etc. If you burn coal, the gas given off is carbon dioxide.
Transportation and electricity are two very large factors in the emission of carbon dioxide. Transportation includes, planes, cars, trains, and buses. Transportation is a very large polluter of carbon dioxide, because we need to use fossil fuels to make them work, and fossil fuels emit a lot of carbon dioxide.
The reason electricity gives off so much carbon dioxide is because in order for electricity to work, once again, we need to use fossil fuels. Different fossil fuels give off different amounts of carbon dioxide, so we can make better choices to help the planet. Industry gives off carbon dioxide not only because of their use of fossil fuels, but chemical reactions taking place (production of cement) can also let off CO2.
