Global warming is when the earth heats up and the temperature rises. This is caused by green house gases trap heat and light from the sun in the earth’s atmosphere which in turn causes the temperature to increase. Examples of these greenhouse gases are carbon dioxide, methane, carbon monoxide and nitrous oxide. (library.thinkquest.org, 2011).…
Global Warming is an issue demanding of world wide attention, yet widely ignored. Global Warming will change our planet drastically yet under the benefit of cheap energy we do nothing to shrink our carbon footprints. Many ignore the topic of Climate Change as they don’t believe in it, or simply don't understand why they should bother. This is exactly what Michael Pollan trys to argue in his article, “Why Bother?”, published by The New York Times,…
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.…
There are many questions about global warming, from its causes to its effects, and many people even question whether or not it even exists. Global warming is described as the increase of the average temperature of the Earth caused by increasing concentrations of greenhouse gases produced by human activities, such as deforestation, use of fertilizers, fossil fuel combustion and cement production. According to the global warming theory, the intensification of industrial activities during the twentieth century (based on the fossil fuel combustion such as petrol and coal) increased the concentration of CO2 in the atmosphere.…
Global warming refers to an increase in global temperatures that happens at a gradual scale and has been attributed to the greenhouse gasses produced by industries through the release of chlorofluorocarbons, carbon dioxide and many other air pollutants (Haldar). The gasses trap heat energy from the sun causing the gradual increase in temperatures. Global warming has had negative impacts on many ecosystems around the world among them droughts, unpredictable weather patterns, sea level rises and retreating of the major ice sheets due to melting. Global warming has had an effect even on the arctic tundra. Most researchers agree that human activity is the most responsible for causing global warming.…
Another way that humans cause global warming is by deforestation, which lowers the amount of oxygen being produced and carbon dioxide being consumed because there are less plants to facilitate these processes. This increases carbon dioxide emissions and this release of carbon dioxide heats the atmosphere. According to the National Oceanic and Atmospheric Administration, when carbon dioxide is emitted into the atmosphere, it absorbs infrared photons rising from the surface and re-emits them back towards the surface. This creates a constant heat loop which essentially heats the Earth because heat can not escape the atmosphere.…
What is global warming? Global warming is the increase in the average temperature of Earth’s surface air and oceans. This is a result of greenhouse gas; such as carbon dioxide, water vapor, nitrous oxide, and methane that traps heat and light from the sun in the Earths atmosphere. This is known as the greenhouse effect. A good example of the greenhouse effect would be your automobile. When you leave your car parked in the sun on a hot day with all the windows up, the temperature of your car will rise. This happens because the heat and light from the sun can enter into the car through the window, but it cannot exit. This is what the greenhouse effects do to our earth. The heat and light can get through the atmosphere, but it cannot get out. As a result, the temperature of earth’s surface air and oceans rises. Although the greenhouse effect is what allows us to live on earth, if too many greenhouse gases get trapped in Earths atmosphere, earth can get unusually warm.…
For the past decade now there has been a long ongoing controversy, this controversy being this issue of global climate change. It has been a subject many people have been aware of yet few have actually talked about with the general public, as a result is has become one of the most undermined, yet widely discussed issues being held today amongst primarily scientists. Although scientist heavily debate on the subject, making suggestions on what needs to be done and pointing out the causes for climate change; we as a group need to take action in finding out what is happening to the Earth. It is only educating the general public is the only way we can come closer to reversing the damaged caused by global warming and climate…
The earth has been around for billions of years and many issues in our time as a species have risen up. One matter that has come up is the issue of global warming or climate change. This conflict has been around for many years, but has started to get worse every year, since the United States and other countries have been emitting carbon dioxide into the earth’s atmosphere. Global warming is an urgent issue; moreover, there exists a controversy on whether humanity or nature is the cause, and the scientists who consider this a serious matter are entirely correct because humans are at fault.…
Global warming is the name given by scientists for the gradual increase in temperature that is from 15 Celsius to 22 Celsius of the Earth's surface that has worsened since the industrial revolution…
of us in the near future. It is very harmful to the environment, but can also be delayed.…
Global warming refers to the rise in the average temperature of the atmosphere due to the effect of greenhouse gases.…
These events are already here and will get much worse in future if we don’t act.…
Other scientists subscribe to the theory that global warming of the earth is taking place due to something called the greenhouse effect. According to this hypothesis, carbon dioxide is released into the air by the burning of fossil fuels and is trapped in the atmosphere, causing a rise in temperatures. If you agree with this theory, then you place responsibility on people and their life-styles for the warming trend and believe that action should be taken to slow down this trend.…
