Global Warming And The Greenhouse Effect

Good Essays

Global warming is the increase in the average surface temperature of the Earth due to the effect of the buildup of greenhouse gases, due to deforestation and burning fossil fuels which causes the heat to be trapped that would otherwise escape from the earth. To understand global warming, you need to understand the greenhouse effect. The greenhouse effect is actually essential for life on earth to exist as it allows the planet to remain warm enough to sustain life. For example if we consider for moment a simplistic comparison of a car parked in the sun. The rays of the sun enter the car through the windows and some of the heat is absorbed by items inside the car (seats, dashboard etc). These objects will in turn begin to release heat and some of this heat escapes back through the windows but some of the heat is reflected back into the car. The result is that more heat enters the car than is able to escape it and the interior of the car warms up. So if you think of the earth’s atmosphere as the car’s interior. The landscape and structures on earth can be seen as the cars seats and dashboard. The role of the cars windows is played by certain things within the earth’s atmosphere such as carbon dioxide, methane gas and water vapour which absorb the heat reflected by the earth below. These are known as greenhouse gasses.
When there are more greenhouse gasses present in the atmosphere, more heat can be retained leading to a rise in the temperature of our planet. This is what I
