Climate change - Essay Example After that, the volume and pattern of warming that is been recorded, cannot be described by these factors alone. Studies shows there's a lot greenhouse gases (GHGs) emitted by humans that speeded up the causes of climate change. This evidences includes glaciers have melted and retreated dramatically, ocean acidification, oceans are getting warmer, and wild climates such as hurricanes and typhoons. Driving cars, deforestation of tropical forests, the emissions of gases from fossil fuel power plants and the increase habit of using chemical fertilizers on agricultural land are some the great factors the contribute the global warming. Levels of GHGs have gone up and down but it stays constant for thousands of years. Scientist usually use the term â€Å"climate change† instead of global warming because Earths average temperature rises and ocean heat spread around the globe cools some areas and on the other hand warms others. Below shows the illustration on the effect of climate cha nge. Studies also show that the Greenland ice is thinning. Some fear that the melting of ice sheet in Greenland could dramatically increase the sea levels. Ice also acts as a solar reflector. Less ice means the less heat reflects. For what we understand in oxygen and carbon dioxide cycle is that, the oxygen we breath comes from plants while human and animals produces carbon dioxides in which plants needed to produce their own food. With the growing industry for wood and paper products and with the use of forest for fuel, contributes to the mass deforestation around the globe. With less forest and a large volume of carbon dioxide from the atmosphere, it contributes to the increasing temperature of earth. Typhoon Ketsana is one of the devastating typhoons that hit the Philippines last 2009.Flood water levels reached 6.1 meters. Affected residents were sent on their rooftop for refuge. Typhoon Ketsana killed 246 people in the Philippines and 32 in Vietnam. The typhoon Ketsana has becom e the focus of marathon discussion of climate change all over the world. Experts say that it is an example of climate disaster which poor nation, such as Philippines could face in warmer world. Below is a picture of victims of typhoon Ketsana Another man-made cause of global warming is the increase of human population. More people indicate more foods. That means more methane because more burning of fuel from transportations and power plants. Since more people needs more foods we have to raise food. Cattles is a good example of food. One source of methane is manure. This means more manure and more methane produced in the atmosphere. Global climate debates continue. Some also believes that global warming is a natural cycle and not caused by human. It is a natural process caused by volcanic eruptions, sun spots, changes on Earth orbit or the Earth changes towards the sun. Some also believed that the cause of increasing temperature in Earth is the activity of sun itself. The star which is at the center of solar system is getting warmer. Some experts also say that if we sum up industrial pollution of mankind, it is only just like a few volcanic eruptions For thousands of years, increasing temperature and the melting of glaciers has been observed. Whether the result is due to greenhouse gases or the sun’s natural cycle, we cannot deny the fact the temperature is rising. Whether global warming is man-made or not we can do something about it.
