Question

essay on global warming

Answer 1

Global warming is the increase of world's average temperature, mainly in the sector of atmosphere, seas and the land on Earth. here are three serious factor, namely the crack on the lower part of atmosphere, pollution on Earth an so many green houses. The first factor is on the atmosphere. Recent years, many researches show that atmosphere has some kind of crack because of the heat from sun's emission. The layer of atmosphere seems can not take the heat anymore. The crack gets larger as the sun-ray holds in the atmosphere as there are gases as what it seems to be the cause. This second factor, pollution, takes its toll as the one which makes the sun-ray stuck n the atmosphere. These gases are very thick that even the sun-ray can not get through it, or at least it is hard to do it. The third factor is that the green houses, reflected the sun-ray that supposed to be stayed on Earth sending the sun-ray back to space, but remember though, there is the gases that block the process of sending away the sun-ray. If the green houses don't stop being built, that will just be a helpful tool to make the atmosphere and our Earth worst. From these explanations, details and examples, my conclusion is that someone has got to do something and not just keep inventing new technology or fancy factories because what we need now is not something that can make life easier but something that can decrease the temperature.

Answer 2

Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming. The 29th century is experiencing a continued increase of Earth’s mean atmospheric temperature by about 1.4 degrees F and about two thirds of it occurring since 1980.  This is global warming is affecting the nature’s balance and has a huge impact on life like continued heat waves, and sudden occurrence of storms and floods. Don’t we see time to time the epidemics that are devastating to human life and the flooding of the farmlands that puts economy in a deep hole? Scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from non -stop burning of fossil fuels and the razing of tropical forests. Since the industrial revolution till this day, there is a constant emission of the carbon into the atmosphere, everything we do we leave carbon footprints. It is a man made cause of the global warming.  The global emissions jumped 3 percent in 2011 and are expected to jump another 2.6 percent in 2012, researchers reported. The greenhouse effect is a process by which the greenhouse gases absorb thermal radiation; these are then reradiated in all directions. But when some of these radiations come back to the surface and lower atmosphere, it causes increase in the average surface temperature leading to global warming.
