Essay about Global Warming - 601 Words

Global Warming Global Warming is an important ecological issue and has many negative effects upon our environment. Global Warming, or what has been called the Greenhouse effect, is the result of a fourfold ecological process. 1-Sunlight radiates from the sun, through space, to Earth’s atmosphere. 2- The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm. 3- Infrared rays, that are remitted into the atmosphere are trapped by greenhouse gases. 4- The gas then absorbs the light and is remitted back to the Earth’s surface and warms it even more. Left on its own this natural process keeps our†¦show more content†¦Activities such as fossil fuel combustion, waste disposal, the use of refrigerators, agricultural and industrial activities, and the cutting down of forests have all played a significant role in the spread of these gases. These, and other human practices, have changed the chemical make up of the atmosphere. Between pre-industrial times and today, carbon dioxide concentrations have been on the rise. With these higher levels of gas concentration in our atmosphere the Earths climate is slowing changing for the worse. The temperature of the Earth’s surface is as warm, if not warmer than it has been in any other century. One study, conducted by the IPCC (Intergovernmental Panel on Climate Change) said that unless governments do something to restrict the emissions of greenhouse gases to a lower level, global temperatures could rise 1.6 to 5.3 degrees Fahrenheit by the year 2100. This increase is significant, because it represents the fastest global warming since the end of the last ice age more than 10,000 years ago (Houghton and Griggs). One result of these warmer temperatures is drought. With the warming of the planet, the water on the ground would quickly evaporate causing rivers and lakes to dry. This would lead to crops dying from lack of rain, which would lead to increased food prices and other associatedShow MoreRelatedGlobal Warming And The Warming1544 Words   |  7 PagesGlobal warming has become a well conversed topic among scientists and peoples in the world today. There are extremists who do everything possible to stop contributing to the warming, but the average person does little to alleviate the issue and in many cases refuses to acknowledge that there is a problem at all. Dating back to millions of years ago, even before humanity was born, the world has always experienced one form or another of warming; so the warming seen today is not as bizarre as many mayRead MoreGlobal Warming And The Warming1353 Words   |  6 PagesGlobal Warming With it being the presidential election season the talk of global warming, also known as climate change has come up in conversation more. But should it be associated with whether you are republican or democrat? Global warming should not be rather you â€Å"believe† in because it is a stated fact.

Global warming is affecting the world economy, the overall health of the population, and most importantly the environment that surrounds us. Ignoring this problem will not just make it suddenly disappear; the world has to make an effort to stop it while it can still be maintained. Accepting the fact that it is happening is just the first step, the next step is takingRead MoreGlobal Warming1677 Words   |  7 PagesThrough the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since theRead MoreGlobal Warming1410 Words   |  6 PagesGlobal warming was first mentioned by ‘Svante August Arrhenius in 1896’, but in ‘1753, Joseph Black discovered carbon dioxide’ and in ‘1827, Jean-Batiste Fourier suggested that atmospheric effect kept the earth warmer than it would otherwise be’, (Direct.gov. n.d. A history of climate change). Since this time, reports, and study have be done with graphs to show the impact of global warming and what could happen to our planet. In 1979, the first conference was held this was called ‘International climateRead MoreGlobal Warming1245 Words   |  5 PagesGlobal Warming The major threat of today’s world is global warming. Due to various reasons global warming turns out to be a serious issue in the last few years. Today people believe in global warming while this concept was not so much believed and people interpreted in some other meanings what was happening in the past. Global warming is amplification in the temperature of earth because of industrial pollution, fossil fuels, and agricultural practices caused by human being, other and natural gasRead MoreGlobal Warming1316 Words   |  6 PagesControversy over Global Warming One of the largest argued topics in our world today is over global warming. People argue that is real, and others argue that it is fake. The effects of global warming create a growing danger for the ecosystem we live in by damaging glaciers and weather patterns. Humans contribute to global warming yet non-believers will think otherwise. Global warming is the greatest challenge facing our planet.

Climate model projections made by the US Intergovernmental Panel on Climate Change (IPCC) show that, recently, global temperature has increased. This increase in temperature is referred to as global warming. One of the main causes of global warming is greenhouse gases. Greenhouse gases are gases in the atmosphere that absorb solar radiation to keep the planet warm. These gases have increased, so more solar radiation is trapped ins ide raising global temperaturesRead MoreGlobal Warming1050 Words   |  5 PagesTake a position: Global warming is a real problem. 1000 word Essay. Using persuasive technique Global warming is the increase in the average temperature of Earth’s surface. Since the late 1800’s, the global average temperature has increased about 0.7 to 1.4 degrees F (0.4 to 0.8degree C). Climate change is happening and its effects are real.
