I am going to be telling you about 5 independent variables that are contributing to the cause of a problem the world is currently faced with, global warming. What is global warming? Well, global warming is a rise in the Earth 's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect (which I will talk more about.) Which is when our ozone layer has a hole which gradually increases, and increases heat from the sun. This causes major problems such as the polar caps melting and increase of temperatures on Earth. The number one cause of global warming is the large amount of greenhouse gases being released into our atmosphere on a daily basis. So, as the amount of greenhouse gases being released into the atmosphere increases, global warming increases. You may be asking how greenhouse gases are associated with the increase of global warming. Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide and ozone. These are all formed through the process of burning fossil fuels. Methane traps the sun 's heat in the earth 's atmosphere with the help of the other greenhouse gases through a naturally occurring process known as the greenhouse effect. During the day, the sun shines through the atmosphere. Earth 's surface warms up in the sunlight. At night, Earth 's surface cools, releasing the heat back into the air. But scientists have noticed a high increase in the amount of greenhouse gases being
