Glaciers are melting, sea levels are rising, forests are drying and wildlife is suffering, these are all results of the apparent rise in global temperatures and it has become more obvious that humans over centuries are releasing harmful heat-trapping gases into the atmosphere known as greenhouse gases. The greenhouse effect causes the increase in global temperature as the gases which are released into the atmosphere allow light to be entered, but prevents heat from escaping.…
The sky is falling, the sky is falling! Growing up I heard this phrase in folktales as a “wolf cry”-- a cry that is so ridiculous that nobody would believe it. Now that global warming is a major environmental issue, the saying doesn’t sound so out of place. Most people might say: what is global warming? That’s the question that was running through my mind when I first heard we were watching a documentary on it in my English 130 class. The film is Al Gore’s An Inconvenient Truth and it is about the causes of global warming and what it is doing to our planet. Being an environmentally involved citizen and growing up with conservative Republicans as parents, I was torn between not really liking Gore and this extreme reality that I felt was an impending doom on Mother Earth. The day before my writing class my dad called me and I brought up the fact that I was watching Gore’s film; his reaction was, “I’m paying for you to do that?” I tried to tell him it wasn’t about Gore and when I brought up global warming he claimed it was a scheme to get money and that our wor...…
In the last century, the sea level has rose for about 17 centimetres. The rate in the last decade is however, nearly the double of last century. Major global surface reconstructions also showed that the Earth has warmed since 1880 and it’s still going on. Oceans are also warming up, due to the heat. Not only that, the Greenland and Antarctic ice sheets are melting, glaciers are disappearing and extreme weather events have occurred more often. All these phenomena are the evidence of the fact that the Earth is warming up, they are the cause of global warming. Many scientists and researchers are trying to find a way to reduce the heat that the Earth absorbs. But in order to do that, they need to answer one question: What is the main cause of global warming. Is it we, humans, or is it the sun that causes it? Many debates are being held about this topic. Not only that, even documentaries were made about it, like The Great Global Warming Swindle and The inconvenient truth. But still, no one knows whether we, humans, causes global warming or the sun.…
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 has been around our Earth for centuries, but recently has become a bigger problem for our environment. There has been debate whether or not global warming is a natural occurrence for our planet, and doesn’t really exist. While others argue that human activities is causing global warming. Global warming is caused by many things such as pollution that is damaging our environment. The causes are split up into two groups. There are the natural or anthropogenic causes, and then there is the man-made human activity that causes damage to our Earth more. Some people believe that the natural causes are a release of methane gas from arctic tundra and wetlands, and that the Earth is going through a natural phase that we have no control over. Many believe that though man-made pollution is what is causing global warming to occur. There are more man-made causes that do more damage because there are various causes rather than the natural causes that occur. One of the biggest causes is pollution because pollution comes in various forms and sizes. Gases known as greenhouse gas emissions kill our environment due to the deadly gases that are released into our atmosphere destroying our o-zone layer. These gases can come from factories, cars, electrical appliances, even the manufacturing of them. The fact that man-made activity is causing our pollution and there is statistics that show an increase of a rise in temperature due to greenhouse gas emissions. The problems begin when human activities distort and accelerate the natural process by creating more greenhouse gases in the atmosphere than are necessary such as in factories.…
Humans are responsible for global warming for many reasons and if it is not controlled properly it can affect the future of this planet. The burning of fossil fuels, mass deforestation, and increased population are all causes of global warming. "Global warming is believed to be caused by changes in the earth 's atmosphere as a result of industrial process."(Leggett 124) Global warming is the rise of Earth’s temperature causing a vast amount of issues. The sign that supports the human cause is abundant and powerful, some say it is normal for the planet to undergo such changes in atmospheric temperature. If we, as humans, do not change the way we use resources, our planet will be doomed for the future.…
Global warming causes many of the disastrous problems we have in our world today. The causes of global warming is what most people would be shocked about and some of the causes are being used almost every day. One cause of global warming is carbon dioxide being admitted into the air by the burning of fossil fuels. Two things that emit this is factories and cars. One used to meet the demand of buyers and the other used daily by millions around the world. A second cause is deforestation. The effects that these two causes lead two are plentiful. However, the two effects are even more dangerous storms coming our way and the extinction of animals. The more storms that come our way the more money, lives and homes we begin to lose. When it comes to the extinction of animals, we need them to survive. Without some of these animals, many people would starve. In conclusion, these are only two causes and effects of global warming, and the results are horrible.…
Global warming is the result of human actions. The atmosphere is changing, and the ozone layer is under the threat from chemicals that people use on the earth. The amount of using fossil fuels, such as oil, gas, coal, and deforestation produces carbon dioxide.…
In the mid-twentieth century the earth’s average temperature is increasing due to the fact that global warming is taking place. Global surface temperature has increased about a degree in the past century. The progressive gradual rise of the earth's surface temperature thought to be caused by the greenhouse effect is responsible for changes in global climate patterns. An increase in the earth's atmospheric and oceanic temperatures is widely predicted to occur due to an increase in the greenhouse effect resulting from pollution. Atmosphere carbon dioxide (CO2) is known as a Greenhouse gases, which means the increased levels of carbon dioxide in the atmosphere can lead to global warming which could affect the world’s environment. Scientists have determined that humans are responsible for the increases by use of cars, industries, and forest fires. An increase in the amount of carbon in the air results in more acidic rain which may cause harm to the environment, the water we drink, and the vegetables we plant. The way that these temperatures are increasing it is projected to rise 3-8 F by 2050. The three focuses of the global warming theory are Greenhouse Gases, the possible effects of greenhouse gases, and ways to limit greenhouse gases.…
Nowadays with all this technological advances and equipment we are able to determine that that distant future may not be so distant at all. The Earth is warming and it affects us all. Take this spring for example. In early March of this year we have experienced record-breaking temperatures. Temperatures that have reached low eighties, temperatures that are normally seen in Chicago during the summer months. Global warming is the theory that causes an increase in the average temperature of Earth's atmosphere and oceans motivated by the greenhouse effect caused by emissions of carbon dioxide and other gases. Global warming not only affects the temperature, but also affects the global rainfall, cloud covers and all other elements of the atmospheric system. Burning oil, coal and natural gas has caused increased carbon dioxide in the atmosphere and produces the resulting increase in temperature. This phenomenon can cause drastic changes to our planet and one of them will be the melting of the polar ice caps. Temperatures will continue to ascend if greenhouse gases emissions continue. Therefore new energy sources must be explored and developed in order to reduce the emission of carbon dioxide into the atmosphere. The Earth’s temperatures are rising drastically, which would make it difficult for the world's ecosystems to adapt at such rapid rate.…

With the rise in the Machine Age during the late 1800’s, early scientists believed that the byproducts released by these new machines would have adverse effects on the environment. The scientists began to study these effects and noticed that the earth’s global temperature was rising 1.4 degrees Fahrenheit every few years. This was the beginning basis for the scientific theory of Global Warming. Global warming has since become one of the most passionate yet controversial scientific studies. There have been many heated political debates over whether or not the theories and supporting evidence are valid or if they are over exaggerated yearly weather occurrences. While many critics disagree with the theories behind global warming, those who do believe in these theories are supported by the evidence of the rise in the global means temperature, rise in the sea level, extreme weather, and geological changes. This paper will refute all arguments against the existence of global warming by proving that global warming is affecting our planet and that it needs immediate long term attention.…
The main cause for the Global Warming is the increase in the concentration of green house gases which is being let out by the activities of human beings. A study has shown that the main reason for Global Warming is the increase in the production of Carbon dioxide from Cement production, fossil fuel, and deforestation. A report in 2013 states that, human is the main cause of the Global warming which lead to the reduction in snow in Antarctic and Arctic regions, which paved way to the increase in the sea level. This effect will include increase in sea level, expansion of subtropical Deserts. Warming is expected to be higher in the Arctic regions. This has a lot of effects which will create lot of changes in human life; like heavy rainfall, heat waves, ocean acidification, and extinction of some species. Emission of green house gases have increased about 2.2% from 2000-2010.…
Over the course of the past century, the Earth s global temperature has risen by about one degree Fahrenheit. This may not seem like a large increase, but given the time period in which this increase occurred, the change is quite amazing. Some scientists argue that this one-degree increase is just the Earth s natural changing climate, but others believe that it is due to global warming. More and more scientists are becoming convinced of global warming and its dangers. Global warming is a phenomenon that occurs when fossil fuels are burned and greenhouse gasses are ejected into the atmosphere and burn ozone; the shield that reflects ultra violet rays from the sun. Global warming doesn t just affect the temperature; it also affects all aspects of climate and weather.…
