Light rays from the sun bombard the earth with enormous amounts of radiation that enter the earths atmosphere (1).The greenhouse gases absorbs infrared radiation when it bounces off of the earth, in the form of heat which is circulated in the atmosphere and eventually some is lost to space (2). The greenhouse gases mostly influence the temperatures of the earth and without the greenhouse gases there would be low temperatures (2). The greenhouse gases make the earth habitable for living organisms by providing warm temperatures (2). The greenhouse gases trap the heat and warm the earth hence making the earth suitable to live in for living organisms, although excess greenhouse gas emission in the atmosphere may lead to drastic changes that may make the earth to be unsuitable to live in (3). The greenhouse gases affect the weather and the climate system (3). The increase in greenhouse gases, which is causing climate change are largely from burning fossil fuels (CO2) and agriculture (methane) (4).
