Global warming is a progressive increase in the temperature of the earth's atmos-phere which customarily applies to the greenhouse effect, (the trapping of the sun's warmth in a planet's lower atmosphere), caused by increased levels of carbon dioxide and other pol-lutants. With the increasing temperature of the Earth (due to the sun expanding in size), ‘global warming is expected to occur in the future, glaciers will continue to melt and sea levels rise’ quoted by environmentalist, Tim Flannery.…

Global warming is the rise of average temperature in the earth’s atmosphere since the late 19th century. Since the beginning of the early 20th century, the earths mean surface temperature had increased by around 0.8 degrees. Warming of the climate system had become more obvious and scientists are 90% sure that the main cause of the increase in temperature in due to the increasing concentrations of greenhouse gases due to human activities such as deforestation and burning of fossil fuels.…

Global warming’s a severe concern that is plaguing our environments and communities. Global warming occurred when the rise in the average temperature of both the Earths atmosphere along with the oceans. Since early 20th century the Earths temperature has continued to raise giving merit to the beliefs that global warming warrens concern. Jiansong (2011) believed tropical storms became worse over the years and global warming has become such an issue become such an issue it needs to be combated. Miller (2012) preformed experiments to measure the change in the earth’s tempters over the years. Venkataramanan (2011) believed that global warming…

Global Warming refers to the gradual increase in the Earth’s temperature as a result of the growing concentration of human induced green house gases which are carbon dioxide, chlorofluorocarbons and hydro fluorocarbon in our atmosphere. Global warming can be caused by the use of fossil fuels, and industrial or agricultural processes. Man-made emissions are adding to the amount of carbon dioxide already being naturally released. These harmful processes have been leading to a large increase in the buildup of "greenhouse gases," which are carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapors. Global warming is an extremely severe problem facing the world today. Its effects and causes have been on the rise and people need to do something about it before the problem gets any worse. There are several ways to reduce the effects of global warming.…

Global warming refers to the increase in the average temperature of both the earth’s near surface air and the oceans. The temperature increase began in mid twentieth century and is predicted to continue into the future. For example, during the last hundred years ending in 2005, the earth’s surface air temperature has increased drastically (Thomas, C. D, 2004). Basically, global warming is the recent increase in the average air and ocean temperature of the Earth as well as its expected continuation. What is so controversial about it is the actual potential for danger and its causes. Though natural events like volcanoes and solar changes have caused small rises in temperatures over time, many believe that greenhouse gas emissions have a large part in this and that even if the emission levels stabilize, temperatures may continue rising for another thousand years or more. It is projected by the Intergovernmental Panel on Climate Change (IPCC) that the average global surface temperature will probably rise another 1.1-6.4 °C (2.0 to 11.5 °F) during this century. Right now the average temperature of the Earth is about 13 °C, or 56 °F.…

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. However, the larger the change in climate, the more negative the consequences will become. Global warming will make life harder for most people .When the carbon-dioxide level doubles, the temperature will go up by 5 degree Celsius. It would lead to melting of polar ice caps, rise in sea level and there would be dramatic changes in the map of the world. Global warming has been experienced all over the world. In U.S.,average temperatures have been rising because of climate change. As a result, the growing season has lengthened; tree has been sucking more carbon. Global warming is the biggest and most serious problem faced by us today.…

The advancement of technology has brought many convenience and benefits into our lives. Gone were the days when the older generations are needed to walk hundreds and hundreds of miles just to reach a destination and feel very tired and exhausted in the end. During this modern age, we can reach the destination in a very short time and without much energy wasted too. But as we become more dependent to technology, we often abuse it. The rate of factories and automobile being built has increased drastically throughout the years. This has lead to a very worrying problem that is seriously affecting our planet lately; this problem is known as Global Warming. Global warming as its name states is a global phenomenon with a number of effects that is happening in the global level. (D’Silva 2007). Global warming is poses a great threat to our personal lives and also to our world. More and more problems that are happening around us are mainly because of global warming. Our earth is not the same place anymore compared to decades ago, it is now slowly dying and this is a very serious issue that all of us should pay attention to.…

Global warming is the result of the greenhouse effect, which has increased since the human race started to burn fossil fuels in order to extract energy. When fossil fuels are being burnt, greenhouse gasses, such as carbon dioxide, set free into the atmosphere. The accumulative pollution causes the atmosphere to reflect heat radiation back towards the earth, instead of letting the gasses disappear into space, because the ozone layer gets thicker. However, without the greenhouse effect, our planet “would be 33 degrees Celsius cooler“ (“McKibben” 4). Since the carbon dioxide has already increased by one third in the atmosphere since the nineteenth century, the effect will be stronger and therefore more heat will be kept inside the atmosphere than before. This phenomenon, called global warming, leads to a hotter climate; as a matter of fact, the earth is today hotter than it has been in over 2000 years (“McKibben” 5-9).…

Global Warming is an issue that the World has been dealing with for many decades. I really did not understand about Global Warming until I enrolled in a Meteorology class at American Public University, and it was then that I was introduced to the issue of Global Warming, and the damage that is happening to our World. Global Warming refers to the gradual warming of global average temperatures due to the slow increase concentrations of greenhouses gases, primarily carbon dioxide. Burning of fossil fuels traps the heat in the atmosphere making the earth warmer. The signs of climate change are everywhere. Temperatures are warmer, snow melts earlier, and birds do not fly as far south for the winter as they once did. Giant ice sheets are melting and oceans are rising. If our planet continues to warm, because of greenhouse effects there can be more storms, flooding, droughts, heat waves, and it will begin to effect the eco system and some of our plants and animals face the danger of extinction.…

Cyclical global weather patterns and the increased usage of carbon emissions have lead to an increase of global warming. These higher temperature recordings are due to normal weather patterns according to scientists. Although there is an increase in global carbon emissions, the fact that climate measurements have been increasing since the beginning of the 20th century, long before society began using fossil fuels as an energy source in large amounts, illustrates the idea that “global warming” is actually just a normal, cyclical global weather phenomenon. According to the National Climatic Data Center of the National Oceanic and Atmospheric Administration, the average temperature in 2012 was 55.3 degrees, which is 3.2 degrees higher than the 20th-century average (NCDC). These weather patterns are “described as part of a longer-term trend of hotter, drier and potentially more extreme weather” (Eilperin 1). However, the increased usage of carbon emissions is also contributing to the increase of global temperarures. According to a Global Carbon Project report, along with the record high global temperature average that rise every year, carbon emissions also rose 54%, and will continue to rise in the future. This correlation between record high global temperatures and an increase in carbon emissions proves the point that when carbon emissions rise due to an increase in human populations, temperatures are affected by what scientists call the greenhouse effect. Although the Kyoto Protocol, an international treaty that “imposes concrete reductions in greenhouse gas emissions on a number of industrialised countries” (“The Kyoto Protocol”), was supposed to cut the world’s greenhouse-gas output, the yearly increase of the world’s population will call for more energy usage. In fact, the World Resources Institutes predicts that 1,200 new coal plants have already been proposed for construction (Yang). When one of the cheapest energy…
